Chapter 1. Cluster lifecycle with multicluster engine operator overview The multicluster engine operator is the cluster lifecycle operator that provides cluster management capabilities for OpenShift Container Platform and Red Hat Advanced Cluster Management hub clusters. From the hub cluster, you can create and manage clusters, as well as destroy any clusters that you created. You can also hibernate, resume, and detach clusters. Learn more about the cluster lifecycle capabilities from the following documentation. Access the multicluster engine operator Support matrix to learn about hub cluster and managed cluster requirements and support. Notes: Your cluster is created by using the OpenShift Container Platform cluster installer with the Hive resource. You can find more information about the process of installing OpenShift Container Platform clusters at Installing and configuring OpenShift Container Platform clusters in the OpenShift Container Platform documentation. With your OpenShift Container Platform cluster, you can use multicluster engine operator as a standalone cluster manager for cluster lifecycle function, or you can use it as part of a Red Hat Advanced Cluster Management hub cluster. If you are using OpenShift Container Platform only, the operator is included with subscription. Visit About multicluster engine for Kubernetes operator from the OpenShift Container Platform documentation. If you subscribe to Red Hat Advanced Cluster Management, you also receive the operator with installation. You can create, manage, and monitor other Kubernetes clusters with the Red Hat Advanced Cluster Management hub cluster. See the Red Hat Advanced Cluster Management Installing and upgrading documentation. Release images are the version of OpenShift Container Platform that you use when you create a cluster. For clusters that are created using Red Hat Advanced Cluster Management, you can enable automatic upgrading of your release images. For more information about release images in Red Hat Advanced Cluster Management, see Release images .

What's new in Cluster lifecycle with the multicluster engine operator Learn about new features for creating, importing, managing, and destroying Kubernetes clusters across various infrastructure cloud providers, private clouds, and on-premises data centers. Important: Cluster lifecycle now supports all providers that are certified through the Cloud Native Computing Foundation (CNCF) Kubernetes Conformance Program. Choose a vendor that is recognized by CNFC for your hybrid cloud multicluster management. See the following information about using CNFC providers: Learn how CNFC providers are certified at Certified Kubernetes Conformance . For Red Hat support information about CNFC third-party providers, see Red Hat support with third party components , or Contact Red Hat support . If you bring your own CNFC conformance certified cluster, you need to change the OpenShift Container Platform CLI oc command to the Kubernetes CLI command, kubectl . 1.1.1.1. New features and enhancements for components Learn more about new features for specific components. Note: Some features and components are identified and released as Technology Preview . Cluster lifecycle Hosted control planes Red Hat Advanced Cluster Management integration 1.1.1.2. Cluster lifecycle Learn about new features and enhancements for Cluster lifecycle with multicluster engine operator. You can now push custom labels to the automation job pod created by the ClusterCurator . See Pushing custom labels from the ClusterCurator resource to the automation job pod to learn more. You can now automatically apply configurations in the global KlusterletConfig on every managed cluster, without binding a managed cluster to a KlusterletConfig with an annotation. To learn more, see Configuring the global KlusterletConfig . PlacementDecision now works more efficiently by excluding managed clusters that you are deleting. To learn more about placements, see Placement overview . You can now enable a discovered cluster to automatically import supported clusters into your hub cluster with the discovery-operator . Import clusters for faster cluster management. See Enabling a discovered cluster for management You can use the ClusterCurator resource to perform easier, automatic upgrades from Extended Update Support (EUS) to EUS. The spec.upgrade.intermediateUpdate is added to the ClusterCurator resource with the intermediate release value before the final upgrade to the desiredUpdate . Find the procedure and the example at Using the ClusterCurator for Extended Update Support (EUS) upgrades . You can now use the Infrastructure Operator for Red Hat OpenShift to install a cluster in FIPS mode. See Installing a FIPS-enabled cluster by using the Infrastructure Operator for Red Hat OpenShift . The local-cluster is now imported automatically if you have both an AgentServiceConfig and ManagedCluster custom resource with the necessary annotations. 1.1.1.3. Hosted control planes Starting with OpenShift Container Platform 4.16, hosted control planes supports the user-provisioned installation and attachment of logical partition (LPAR) as compute nodes on IBM Z and IBM LinuxOne. To learn more, see Adding IBM Z LPAR as agents . Configuring hosted control plane clusters on AWS is now generally available. You can deploy the HyperShift Operator on an existing managed cluster by using the hypershift-addon managed cluster add-on to enable that cluster as a hosting cluster and start to create the hosted cluster. See Configuring hosted control plane clusters on AWS for details. The --sts-creds and --role-arn flags replace the deprecated --aws-creds flag in the hcp command line interface. Create an Amazon Web Services (AWS) Identity and Access Management (IAM) role and Security Token Service (STS) credentials to use the --sts-creds and --role-arn flags. For more information, see Creating an AWS IAM role and STS credentials . 1.1.1.4. Red Hat Advanced Cluster Management integration You can now automate the import of OpenShift Service on AWS clusters by using Red Hat Advanced Cluster Management policy enforcement with multicluster engine operator for faster cluster management. Learn more at Automating import for discovered OpenShift Service on AWS clusters . You can now discover and automate the import of hosted clusters, as well. Configure Red Hat Advanced Cluster Management to import multicluster engine operator clusters and then use policy enforcement for automation. Learn more at Automating import for discovered hosted clusters . 1.1.2. Cluster lifecycle known issues Review the known issues for cluster lifecycle with multicluster engine operator. The following list contains known issues for this release, or known issues that continued from the release. For your OpenShift Container Platform cluster, see OpenShift Container Platform release notes . Cluster lifecycle Hosted control planes 1.1.2.1. Cluster management Cluster lifecycle known issues and limitations are part of the Cluster lifecycle with multicluster engine operator documentation. 1.1.2.1.1. Limitation with nmstate Develop quicker by configuring copy and paste features. To configure the copy-from-mac feature in the assisted-installer , you must add the mac-address to the nmstate definition interface and the mac-mapping interface. The mac-mapping interface is provided outside the nmstate definition interface. As a result, you must provide the same mac-address twice. 1.1.2.1.2. Prehook failure does not fail the hosted cluster creation If you use the automation template for the hosted cluster creation and the prehook job fails, then it looks like the hosted cluster creation is still progressing. This is normal because the hosted cluster was designed with no complete failure state, and therefore, it keeps trying to create the cluster. 1.1.2.1.3. Manual removal of the VolSync CSV required on managed cluster when removing the add-on When you remove the VolSync ManagedClusterAddOn from the hub cluster, it removes the VolSync operator subscription on the managed cluster but does not remove the cluster service version (CSV). To remove the CSV from the managed clusters, run the following command on each managed cluster from which you are removing VolSync: If you have a different version of VolSync installed, replace v0.6.0 with your installed version. 1.1.2.1.4. Deleting a managed cluster set does not automatically remove its label After you delete a ManagedClusterSet , the label that is added to each managed cluster that associates the cluster to the cluster set is not automatically removed. Manually remove the label from each of the managed clusters that were included in the deleted managed cluster set. The label resembles the following example: cluster.open-cluster-management.io/clusterset:<ManagedClusterSet Name> . 1.1.2.1.5. ClusterClaim error If you create a Hive ClusterClaim against a ClusterPool and manually set the ClusterClaimspec lifetime field to an invalid golang time value, the product stops fulfilling and reconciling all ClusterClaims , not just the malformed claim. You see the following error in the clusterclaim-controller pod logs, which is a specific example with the PoolName and invalid lifetime included: You can delete the invalid claim. If the malformed claim is deleted, claims begin successfully reconciling again without any further interaction. 1.1.2.1.6. The product channel out of sync with provisioned cluster The clusterimageset is in fast channel, but the provisioned cluster is in stable channel. Currently the product does not sync the channel to the provisioned OpenShift Container Platform cluster. Change to the right channel in the OpenShift Container Platform console. Click Administration > Cluster Settings > Details Channel . 1.1.2.1.7. Restoring the connection of a managed cluster with custom CA certificates to its restored hub cluster might fail After you restore the backup of a hub cluster that managed a cluster with custom CA certificates, the connection between the managed cluster and the hub cluster might fail. This is because the CA certificate was not backed up on the restored hub cluster. To restore the connection, copy the custom CA certificate information that is in the namespace of your managed cluster to the <managed_cluster>-admin-kubeconfig secret on the restored hub cluster. Tip: If you copy this CA certificate to the hub cluster before creating the backup copy, the backup copy includes the secret information. When the backup copy is used to restore in the future, the connection between the hub and managed clusters will automatically complete. 1.1.2.1.8. The local-cluster might not be automatically recreated If the local-cluster is deleted while disableHubSelfManagement is set to false , the local-cluster is recreated by the MulticlusterHub operator. After you detach a local-cluster, the local-cluster might not be automatically recreated. To resolve this issue, modify a resource that is watched by the MulticlusterHub operator. See the following example: To properly detach the local-cluster, set the disableHubSelfManagement to true in the MultiClusterHub . 1.1.2.1.9. Selecting a subnet is required when creating an on-premises cluster When you create an on-premises cluster using the console, you must select an available subnet for your cluster. It is not marked as a required field. 1.1.2.1.10. Cluster provisioning with Infrastructure Operator fails When creating OpenShift Container Platform clusters using the Infrastructure Operator, the file name of the ISO image might be too long. The long image name causes the image provisioning and the cluster provisioning to fail. To determine if this is the problem, complete the following steps: View the bare metal host information for the cluster that you are provisioning by running the following command: Run the describe command to view the error information: An error similar to the following example indicates that the length of the filename is the problem: If this problem occurs, it is typically on the following versions of OpenShift Container Platform, because the infrastructure operator was not using image service: 4.8.17 and earlier 4.9.6 and earlier To avoid this error, upgrade your OpenShift Container Platform to version 4.8.18 or later, or 4.9.7 or later. 1.1.2.1.11. Cannot use host inventory to boot with the discovery image and add hosts automatically You cannot use a host inventory, or InfraEnv custom resource, to both boot with the discovery image and add hosts automatically. If you used your InfraEnv resource for the BareMetalHost resource, and you want to boot the image yourself, you can work around the issue by creating a new InfraEnv resource. 1.1.2.1.12. Local-cluster status offline after reimporting with a different name When you accidentally try to reimport the cluster named local-cluster as a cluster with a different name, the status for local-cluster and for the reimported cluster display offline . To recover from this case, complete the following steps: Run the following command on the hub cluster to edit the setting for self-management of the hub cluster temporarily: Add the setting spec.disableSelfManagement=true . Run the following command on the hub cluster to delete and redeploy the local-cluster: Enter the following command to remove the local-cluster management setting: Remove spec.disableSelfManagement=true that you previously added. 1.1.2.1.13. Cluster provision with Ansible automation fails in proxy environment An Automation template that is configured to automatically provision a managed cluster might fail when both of the following conditions are met: The hub cluster has cluster-wide proxy enabled. The Ansible Automation Platform can only be reached through the proxy. 1.1.2.1.14. Cannot delete managed cluster namespace manually You cannot delete the namespace of a managed cluster manually. The managed cluster namespace is automatically deleted after the managed cluster is detached. If you delete the managed cluster namespace manually before the managed cluster is detached, the managed cluster shows a continuous terminating status after you delete the managed cluster. To delete this terminating managed cluster, manually remove the finalizers from the managed cluster that you detached. 1.1.2.1.15. Hub cluster and managed clusters clock not synced Hub cluster and manage cluster time might become out-of-sync, displaying in the console unknown and eventually available within a few minutes. Ensure that the OpenShift Container Platform hub cluster time is configured correctly. See Customizing nodes . 1.1.2.1.16. Importing certain versions of IBM OpenShift Container Platform Kubernetes Service clusters is not supported You cannot import IBM OpenShift Container Platform Kubernetes Service version 3.11 clusters. Later versions of IBM OpenShift Kubernetes Service are supported. 1.1.2.1.17. Automatic secret updates for provisioned clusters is not supported When you change your cloud provider access key on the cloud provider side, you also need to update the corresponding credential for this cloud provider on the console of multicluster engine operator. This is required when your credentials expire on the cloud provider where the managed cluster is hosted and you try to delete the managed cluster. 1.1.2.1.18. Node information from the managed cluster cannot be viewed in search Search maps RBAC for resources in the hub cluster. Depending on user RBAC settings, users might not see node data from the managed cluster. Results from search might be different from what is displayed on the Nodes page for a cluster. 1.1.2.1.19. Process to destroy a cluster does not complete When you destroy a managed cluster, the status continues to display Destroying after one hour, and the cluster is not destroyed. To resolve this issue complete the following steps: Manually ensure that there are no orphaned resources on your cloud, and that all of the provider resources that are associated with the managed cluster are cleaned up. Open the ClusterDeployment information for the managed cluster that is being removed by entering the following command: Replace mycluster with the name of the managed cluster that you are destroying. Replace namespace with the namespace of the managed cluster. Remove the hive.openshift.io/deprovision finalizer to forcefully stop the process that is trying to clean up the cluster resources in the cloud. Save your changes and verify that ClusterDeployment is gone. Manually remove the namespace of the managed cluster by running the following command: Replace namespace with the namespace of the managed cluster. 1.1.2.1.20. Cannot upgrade OpenShift Container Platform managed clusters on OpenShift Container Platform Dedicated with the console You cannot use the Red Hat Advanced Cluster Management console to upgrade OpenShift Container Platform managed clusters that are in the OpenShift Container Platform Dedicated environment. 1.1.2.1.21. Work manager add-on search details The search details page for a certain resource on a certain managed cluster might fail. You must ensure that the work-manager add-on in the managed cluster is in Available status before you can search. 1.1.2.1.22. Non-OpenShift Container Platform managed clusters require ManagedServiceAccount or LoadBalancer for pod logs The ManagedServiceAccount and cluster proxy add-ons are enabled by default in Red Hat Advanced Cluster Management version 2.10 and newer. If the add-ons are disabled after upgrading, you must enable the ManagedServiceAccount and cluster proxy add-ons manually to use the pod log feature on non-OpenShift Container Platform managed clusters. See ManagedServiceAccount add-on to learn how to enable ManagedServiceAccount and see Using cluster proxy add-ons to learn how to enable a cluster proxy add-on. 1.1.2.1.23. OpenShift Container Platform 4.10.z does not support hosted control plane clusters with proxy configuration When you create a hosting service cluster with a cluster-wide proxy configuration on OpenShift Container Platform 4.10.z, the nodeip-configuration.service service does not start on the worker nodes. 1.1.2.1.24. Cannot provision OpenShift Container Platform 4.11 cluster on Azure Provisioning an OpenShift Container Platform 4.11 cluster on Azure fails due to an authentication operator timeout error. To work around the issue, use a different worker node type in the install-config.yaml file or set the vmNetworkingType parameter to Basic . See the following install-config.yaml example: compute: - hyperthreading: Enabled name: 'worker' replicas: 3 platform: azure: type: Standard_D2s_v3 osDisk: diskSizeGB: 128 vmNetworkingType: 'Basic' 1.1.2.1.25. Client cannot reach iPXE script iPXE is an open source network boot firmware. See iPXE for more details. When booting a node, the URL length limitation in some DHCP servers cuts off the ipxeScript URL in the InfraEnv custom resource definition, resulting in the following error message in the console: no bootable devices To work around the issue, complete the following steps: Apply the InfraEnv custom resource definition when using an assisted installation to expose the bootArtifacts , which might resemble the following file: Create a proxy server to expose the bootArtifacts with short URLs. Copy the bootArtifacts and add them them to the proxy by running the following commands: Add the ipxeScript artifact proxy URL to the bootp parameter in libvirt.xml . 1.1.2.1.26. Cannot delete ClusterDeployment after upgrading Red Hat Advanced Cluster Management If you are using the removed BareMetalAssets API in Red Hat Advanced Cluster Management 2.6, the ClusterDeployment cannot be deleted after upgrading to Red Hat Advanced Cluster Management 2.7 because the BareMetalAssets API is bound to the ClusterDeployment . To work around the issue, run the following command to remove the finalizers before upgrading to Red Hat Advanced Cluster Management 2.7: 1.1.2.1.27. A cluster deployed in a disconnected environment by using the central infrastructure management service might not install When you deploy a cluster in a disconnected environment by using the central infrastructure management service, the cluster nodes might not start installing. This issue occurs because the cluster uses a discovery ISO image that is created from the Red Hat Enterprise Linux CoreOS live ISO image that is shipped with OpenShift Container Platform versions 4.12.0 through 4.12.2. The image contains a restrictive /etc/containers/policy.json file that requires signatures for images sourcing from registry.redhat.io and registry.access.redhat.com . In a disconnected environment, the images that are mirrored might not have the signatures mirrored, which results in the image pull failing for cluster nodes at discovery. The Agent image fails to connect with the cluster nodes, which causes communication with the assisted service to fail. To work around this issue, apply an ignition override to the cluster that sets the /etc/containers/policy.json file to unrestrictive. The ignition override can be set in the InfraEnv custom resource definition. The following example shows an InfraEnv custom resource definition with the override: apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv metadata: name: cluster namespace: cluster spec: ignitionConfigOverride: '{"ignition":{"version":"3.2.0"},"storage":{"files":[{"path":"/etc/containers/policy.json","mode":420,"overwrite":true,"contents":{"source":"data:text/plain;charset=utf-8;base64,ewogICAgImRlZmF1bHQiOiBbCiAgICAgICAgewogICAgICAgICAgICAidHlwZSI6ICJpbnNlY3VyZUFjY2VwdEFueXRoaW5nIgogICAgICAgIH0KICAgIF0sCiAgICAidHJhbnNwb3J0cyI6CiAgICAgICAgewogICAgICAgICAgICAiZG9ja2VyLWRhZW1vbiI6CiAgICAgICAgICAgICAgICB7CiAgICAgICAgICAgICAgICAgICAgIiI6IFt7InR5cGUiOiJpbnNlY3VyZUFjY2VwdEFueXRoaW5nIn1dCiAgICAgICAgICAgICAgICB9CiAgICAgICAgfQp9"}}]}}' The following example shows the unrestrictive file that is created: After this setting is changed, the clusters install. 1.1.2.1.28. Managed cluster stuck in Pending status after deployment The converged flow is the default process of provisioning. When you use the BareMetalHost resource for the Bare Metal Operator (BMO) to connect your host to a live ISO, the Ironic Python Agent does the following actions: It runs the steps in the Bare Metal installer-provisioned-infrastructure. It starts the Assisted Installer agent, and the agent handles the rest of the install and provisioning process. If the Assisted Installer agent starts slowly and you deploy a managed cluster, the managed cluster might become stuck in the Pending status and not have any agent resources. You can work around the issue by disabling the converged flow. Important: When you disable the converged flow, only the Assisted Installer agent runs in the live ISO, reducing the number of open ports and disabling any features you enabled with the Ironic Python Agent agent, including the following: Pre-provisioning disk cleaning iPXE boot firmware BIOS configuration To decide what port numbers you want to enable or disable without disabling the converged flow, see Network configuration . To disable the converged flow, complete the following steps: Create the following ConfigMap on the hub cluster: apiVersion: v1 kind: ConfigMap metadata: name: my-assisted-service-config namespace: multicluster-engine data: ALLOW_CONVERGED_FLOW: "false" 1 1 When you set the parameter value to "false", you also disable any features enabled by the Ironic Python Agent. Apply the ConfigMap by running the following command: 1.1.2.1.29. ManagedClusterSet API specification limitation The selectorType: LaberSelector setting is not supported when using the Clustersets API . The selectorType: ExclusiveClusterSetLabel setting is supported. 1.1.2.1.30. Hub cluster communication limitations The following limitations occur if the hub cluster is not able to reach or communicate with the managed cluster: You cannot create a new managed cluster by using the console. You are still able to import a managed cluster manually by using the command line interface or by using the Run import commands manually option in the console. If you deploy an Application or ApplicationSet by using the console, or if you import a managed cluster into ArgoCD, the hub cluster ArgoCD controller calls the managed cluster API server. You can use AppSub or the ArgoCD pull model to work around the issue. The console page for pod logs does not work, and an error message that resembles the following appears: 1.1.2.1.31. installNamespace field can only have one value When enabling the managed-serviceaccount add-on, the installNamespace field in the ManagedClusterAddOn resource must have open-cluster-management-agent-addon as the value. Other values are ignored. The managed-serviceaccount add-on agent is always deployed in the open-cluster-management-agent-addon namespace on the managed cluster. 1.1.2.1.32. tolerations and nodeSelector settings do not affect the managed-serviceaccount agent The tolerations and nodeSelector settings configured on the MultiClusterEngine and MultiClusterHub resources do not affect the managed-serviceaccount agent deployed on the local cluster. The managed-serviceaccount add-on is not always required on the local cluster. If the managed-serviceaccount add-on is required, you can work around the issue by completing the following steps: Create the addonDeploymentConfig custom resource. Set the tolerations and nodeSelector values for the local cluster and managed-serviceaccount agent. Update the managed-serviceaccount ManagedClusterAddon in the local cluster namespace to use the addonDeploymentConfig custom resource you created. See Configuring nodeSelectors and tolerations for klusterlet add-ons to learn more about how to use the addonDeploymentConfig custom resource to configure tolerations and nodeSelector for add-ons. 1.1.2.1.33. Bulk destroy option on KubeVirt hosted cluster does not destroy hosted cluster Using the bulk destroy option in the console on KubeVirt hosted clusters does not destroy the KubeVirt hosted clusters. Use the row action drop-down menu to destroy the KubeVirt hosted cluster instead. 1.1.2.1.34. The Cluster curator does not support OpenShift Container Platform Dedicated clusters When you upgrade an OpenShift Container Platform Dedicated cluster by using the ClusterCurator resource, the upgrade fails because the Cluster curator does not support OpenShift Container Platform Dedicated clusters. 1.1.2.1.35. Custom ingress domain is not applied correctly You can specify a custom ingress domain by using the ClusterDeployment resource while installing a managed cluster, but the change is only applied after the installation by using the SyncSet resource. As a result, the spec field in the clusterdeployment.yaml file displays the custom ingress domain you specified, but the status still displays the default domain. 1.1.2.1.36. A single-node OpenShift cluster installation requires a matching OpenShift Container Platform with infrastructure operator for Red Hat OpenShift If you want to install a single-node OpenShift cluster with an Red Hat OpenShift Container Platform version before 4.16, your InfraEnv custom resource and your booted host must use the same OpenShift Container Platform version that you are using to install the single-node OpenShift cluster. The installation fails if the versions do not match. To work around the issue, edit your InfraEnv resource before you boot a host with the Discovery ISO, and include the following content: apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv spec: osImageVersion: 4.15 The osImageVersion field must match the Red Hat OpenShift Container Platform cluster version that you want to install. 1.1.2.2. Hosted control planes 1.1.2.2.1. Console displays hosted cluster as Pending import If the annotation and ManagedCluster name do not match, the console displays the cluster as Pending import . The cluster cannot be used by the multicluster engine operator. The same issue happens when there is no annotation and the ManagedCluster name does not match the Infra-ID value of the HostedCluster resource." 1.1.2.2.2. Console might list the same version multiple times when adding a node pool to a hosted cluster When you use the console to add a new node pool to an existing hosted cluster, the same version of OpenShift Container Platform might appear more than once in the list of options. You can select any instance in the list for the version that you want. 1.1.2.2.3. The web console lists nodes even after they are removed from the cluster and returned to the infrastructure environment When a node pool is scaled down to 0 workers, the list of hosts in the console still shows nodes in a Ready state. You can verify the number of nodes in two ways: In the console, go to the node pool and verify that it has 0 nodes. On the command line interface, run the following commands: Verify that 0 nodes are in the node pool by running the following command: oc get nodepool -A Verify that 0 nodes are in the cluster by running the following command: oc get nodes --kubeconfig Verify that 0 agents are reported as bound to the cluster by running the following command: oc get agents -A 1.1.2.2.4. Potential DNS issues in hosted clusters configured for a dual-stack network When you create a hosted cluster in an environment that uses the dual-stack network, you might encounter the following DNS-related issues: CrashLoopBackOff state in the service-ca-operator pod: When the pod tries to reach the Kubernetes API server through the hosted control plane, the pod cannot reach the server because the data plane proxy in the kube-system namespace cannot resolve the request. This issue occurs because in the HAProxy setup, the front end uses an IP address and the back end uses a DNS name that the pod cannot resolve. Pods stuck in ContainerCreating state: This issue occurs because the openshift-service-ca-operator cannot generate the metrics-tls secret that the DNS pods need for DNS resolution. As a result, the pods cannot resolve the Kubernetes API server. To resolve those issues, configure the DNS server settings by following the guidelines in Configuring DNS for a dual stack network . 1.1.2.2.5. IBM Z hosts restart in a loop In hosted control planes on the IBM Z platform, when you unbind the hosts with the cluster, the hosts restart in loop and are not ready to be used. For a workaround for this issue, see Destroying a hosted cluster on x86 bare metal with IBM Z compute nodes . 1.1.3. Errata updates For multicluster engine operator, the Errata updates are automatically applied when released. If no release notes are listed, the product does not have an Errata release at this time. Important: For reference, Jira links and Jira numbers might be added to the content and used internally. Links that require access might not be available for the user. 1.1.3.1.

About cluster lifecycle with multicluster engine operator The multicluster engine for Kubernetes operator is the cluster lifecycle operator that provides cluster management capabilities for Red Hat OpenShift Container Platform and Red Hat Advanced Cluster Management hub clusters. If you installed Red Hat Advanced Cluster Management, you do not need to install multicluster engine operator, as it is automatically installed. See the multicluster engine operator Support matrix to learn about hub cluster and managed cluster requirements and support. for support information, as well as the following documentation: Console overview multicluster engine for Kubernetes operator Role-based access control Network configuration To continue, see the remaining cluster lifecyle documentation at Cluster lifecycle with multicluster engine operator overview . 1.2.1. Console overview OpenShift Container Platform console plug-ins are available with the OpenShift Container Platform web console and can be integrated. To use this feature, the console plug-ins must remain enabled. The multicluster engine operator displays certain console features from Infrastructure and Credentials navigation items. If you install Red Hat Advanced Cluster Management, you see more console capability. Note: With the plug-ins enabled, you can access Red Hat Advanced Cluster Management within the OpenShift Container Platform console from the cluster switcher by selecting All Clusters from the drop-down menu. To disable the plug-in, be sure you are in the Administrator perspective in the OpenShift Container Platform console. Find Administration in the navigation and click Cluster Settings , then click Configuration tab. From the list of Configuration resources , click the Console resource with the operator.openshift.io API group, which contains cluster-wide configuration for the web console. Click on the Console plug-ins tab. The mce plug-in is listed. Note: If Red Hat Advanced Cluster Management is installed, it is also listed as acm . Modify plug-in status from the table. In a few moments, you are prompted to refresh the console. 1.2.2. multicluster engine operator role-based access control RBAC is validated at the console level and at the API level. Actions in the console can be enabled or disabled based on user access role permissions. View the following sections for more information on RBAC for specific lifecycles in the product: Overview of roles Cluster lifecycle RBAC Cluster pools RBAC Console and API RBAC table for cluster lifecycle Credentials role-based access control 1.2.2.1. Overview of roles Some product resources are cluster-wide and some are namespace-scoped. You must apply cluster role bindings and namespace role bindings to your users for consistent access controls. View the table list of the following role definitions that are supported: 1.2.2.1.1. Table of role definition Role Definition cluster-admin This is an OpenShift Container Platform default role. A user with cluster binding to the cluster-admin role is an OpenShift Container Platform super user, who has all access. open-cluster-management:cluster-manager-admin A user with cluster binding to the open-cluster-management:cluster-manager-admin role is a super user, who has all access. This role allows the user to create a ManagedCluster resource. open-cluster-management:admin:<managed_cluster_name> A user with cluster binding to the open-cluster-management:admin:<managed_cluster_name> role has administrator access to the ManagedCluster resource named, <managed_cluster_name> . When a user has a managed cluster, this role is automatically created. open-cluster-management:view:<managed_cluster_name> A user with cluster binding to the open-cluster-management:view:<managed_cluster_name> role has view access to the ManagedCluster resource named, <managed_cluster_name> . open-cluster-management:managedclusterset:admin:<managed_clusterset_name> A user with cluster binding to the open-cluster-management:managedclusterset:admin:<managed_clusterset_name> role has administrator access to ManagedCluster resource named <managed_clusterset_name> . The user also has administrator access to managedcluster.cluster.open-cluster-management.io , clusterclaim.hive.openshift.io , clusterdeployment.hive.openshift.io , and clusterpool.hive.openshift.io resources, which has the managed cluster set labels: cluster.open-cluster-management.io and clusterset=<managed_clusterset_name> . A role binding is automatically generated when you are using a cluster set. See Creating a ManagedClusterSet to learn how to manage the resource. open-cluster-management:managedclusterset:view:<managed_clusterset_name> A user with cluster binding to the open-cluster-management:managedclusterset:view:<managed_clusterset_name> role has view access to the ManagedCluster resource named, <managed_clusterset_name>`. The user also has view access to managedcluster.cluster.open-cluster-management.io , clusterclaim.hive.openshift.io , clusterdeployment.hive.openshift.io , and clusterpool.hive.openshift.io resources, which has the managed cluster set labels: cluster.open-cluster-management.io , clusterset=<managed_clusterset_name> . For more details on how to manage managed cluster set resources, see Creating a ManagedClusterSet . admin, edit, view Admin, edit, and view are OpenShift Container Platform default roles. A user with a namespace-scoped binding to these roles has access to open-cluster-management resources in a specific namespace, while cluster-wide binding to the same roles gives access to all of the open-cluster-management resources cluster-wide. Important : Any user can create projects from OpenShift Container Platform, which gives administrator role permissions for the namespace. If a user does not have role access to a cluster, the cluster name is not visible. The cluster name is displayed with the following symbol: - . RBAC is validated at the console level and at the API level. Actions in the console can be enabled or disabled based on user access role permissions. View the following sections for more information on RBAC for specific lifecycles in the product. 1.2.2.2. Cluster lifecycle RBAC View the following cluster lifecycle RBAC operations: Create and administer cluster role bindings for all managed clusters. For example, create a cluster role binding to the cluster role open-cluster-management:cluster-manager-admin by entering the following command: This role is a super user, which has access to all resources and actions. You can create cluster-scoped managedcluster resources, the namespace for the resources that manage the managed cluster, and the resources in the namespace with this role. You might need to add the username of the ID that requires the role association to avoid permission errors. Run the following command to administer a cluster role binding for a managed cluster named cluster-name : This role has read and write access to the cluster-scoped managedcluster resource. This is needed because the managedcluster is a cluster-scoped resource and not a namespace-scoped resource. Create a namespace role binding to the cluster role admin by entering the following command: This role has read and write access to the resources in the namespace of the managed cluster. Create a cluster role binding for the open-cluster-management:view:<cluster-name> cluster role to view a managed cluster named cluster-name Enter the following command: This role has read access to the cluster-scoped managedcluster resource. This is needed because the managedcluster is a cluster-scoped resource. Create a namespace role binding to the cluster role view by entering the following command: This role has read-only access to the resources in the namespace of the managed cluster. View a list of the managed clusters that you can access by entering the following command: This command is used by administrators and users without cluster administrator privileges. View a list of the managed cluster sets that you can access by entering the following command: This command is used by administrators and users without cluster administrator privileges. 1.2.2.2.1. Cluster pools RBAC View the following cluster pool RBAC operations: As a cluster administrator, use cluster pool provision clusters by creating a managed cluster set and grant administrator permission to roles by adding the role to the group. View the following examples: Grant admin permission to the server-foundation-clusterset managed cluster set with the following command: Grant view permission to the server-foundation-clusterset managed cluster set with the following command: Create a namespace for the cluster pool, server-foundation-clusterpool . View the following examples to grant role permissions: Grant admin permission to server-foundation-clusterpool for the server-foundation-team-admin by running the following commands: As a team administrator, create a cluster pool named ocp46-aws-clusterpool with a cluster set label, cluster.open-cluster-management.io/clusterset=server-foundation-clusterset in the cluster pool namespace: The server-foundation-webhook checks if the cluster pool has the cluster set label, and if the user has permission to create cluster pools in the cluster set. The server-foundation-controller grants view permission to the server-foundation-clusterpool namespace for server-foundation-team-user . When a cluster pool is created, the cluster pool creates a clusterdeployment . Continue reading for more details: The server-foundation-controller grants admin permission to the clusterdeployment namespace for server-foundation-team-admin . The server-foundation-controller grants view permission clusterdeployment namespace for server-foundation-team-user . Note: As a team-admin and team-user , you have admin permission to the clusterpool , clusterdeployment , and clusterclaim . 1.2.2.2.2.

Credentials role-based access control The access to credentials is controlled by Kubernetes. Credentials are stored and secured as Kubernetes secrets. The following permissions apply to accessing secrets in Red Hat Advanced Cluster Management for Kubernetes: Users with access to create secrets in a namespace can create credentials. Users with access to read secrets in a namespace can also view credentials. Users with the Kubernetes cluster roles of admin and edit can create and edit secrets. Users with the Kubernetes cluster role of view cannot view secrets because reading the contents of secrets enables access to service account credentials. 1.2.3. Network configuration Configure your network settings to allow the connections. Important: The trusted CA bundle is available in the multicluster engine operator namespace, but that enhancement requires changes to your network. The trusted CA bundle ConfigMap uses the default name of trusted-ca-bundle . You can change this name by providing it to the operator in an environment variable named TRUSTED_CA_BUNDLE . See Configuring the cluster-wide proxy in the Networking section of Red Hat OpenShift Container Platform for more information. Note: Registration Agent and Work Agent on the managed cluster do not support proxy settings because they communicate with apiserver on the hub cluster by establishing an mTLS connection, which cannot pass through the proxy. For the multicluster engine operator cluster networking requirements, see the following table: Direction Protocol Connection Port (if specified) Outbound Kubernetes API server of the provisioned managed cluster 6443 Outbound from the OpenShift Container Platform managed cluster to the hub cluster TCP Communication between the Ironic Python Agent and the bare metal operator on the hub cluster 6180, 6183, 6385, and 5050 Outbound from the hub cluster to the Ironic Python Agent on the managed cluster TCP Communication between the bare metal node where the Ironic Python Agent is running and the Ironic conductor service 9999 Outbound and inbound The WorkManager service route on the managed cluster 443 Inbound The Kubernetes API server of the multicluster engine for Kubernetes operator cluster from the managed cluster 6443 Note: The managed cluster must be able to reach the hub cluster control plane node IP addresses. 1.3. Installing and upgrading multicluster engine operator The multicluster engine operator is a software operator that enhances cluster fleet management. The multicluster engine operator supportsRed Hat OpenShift Container Platform and Kubernetes cluster lifecycle management across clouds and data centers. Deprecated: multicluster engine operator 2.3 and earlier versions are no longer supported. The documentation might remain available, but without any Errata or other updates. Best practice: Upgrade to the most recent version. The documentation references the earliest supported OpenShift Container Platform version, unless a specific component or function is introduced and tested only on a more recent version of OpenShift Container Platform. For full support information, see the multicluster engine operator Support matrix . For life cycle information, see Red Hat OpenShift Container Platform Life Cycle policy . Important: If you are using Red Hat Advanced Cluster Management version 2.5 or later, then multicluster engine for Kubernetes operator is already installed on the cluster. See the following documentation: Installing while connected online Configuring infrastructure nodes for multicluster engine operator Installing on disconnected networks Uninstalling Network configuration Upgrading disconnected clusters using policies MultiClusterEngine advanced configuration Red Hat Advanced Cluster Management integration 1.3.1. Installing while connected online The multicluster engine operator is installed with Operator Lifecycle Manager, which manages the installation, upgrade, and removal of the components that encompass the multicluster engine operator. Required access: Cluster administrator Important: You cannot install multicluster engine operator on a cluster that has a ManagedCluster resource configured in an external cluster. You must remove the ManagedCluster resource from the external cluster before you can install multicluster engine operator. For OpenShift Container Platform Dedicated environment, you must have cluster-admin permissions. By default dedicated-admin role does not have the required permissions to create namespaces in the OpenShift Container Platform Dedicated environment. By default, the multicluster engine operator components are installed on worker nodes of your OpenShift Container Platform cluster without any additional configuration. You can install multicluster engine operator onto worker nodes by using the OpenShift Container Platform OperatorHub web console interface, or by using the OpenShift Container Platform CLI. If you have configured your OpenShift Container Platform cluster with infrastructure nodes, you can install multicluster engine operator onto those infrastructure nodes by using the OpenShift Container Platform CLI with additional resource parameters. See the Installing multicluster engine on infrastructure nodes section for those details. If you plan to import Kubernetes clusters that were not created by OpenShift Container Platform or multicluster engine for Kubernetes operator, you will need to configure an image pull secret. For information on how to configure an image pull secret and other advanced configurations, see options in the Advanced configuration section of this documentation. Prerequisites Confirm your OpenShift Container Platform installation Installing from the OperatorHub web console interface Installing from the OpenShift Container Platform CLI 1.3.1.1. Prerequisites Before you install multicluster engine for Kubernetes operator, see the following requirements: Your Red Hat OpenShift Container Platform cluster must have access to the multicluster engine operator in the OperatorHub catalog from the OpenShift Container Platform console. You need access to the catalog.redhat.com . Your cluster does not have a ManagedCluster resource configured in an external cluster. You need access to the catalog.redhat.com . A supported version of OpenShift Container Platform must be deployed in your environment, and you must be logged into with the OpenShift Container Platform CLI. See the following install documentation: OpenShift Container Platform Installing Your OpenShift Container Platform command line interface (CLI) must be configured to run oc commands. See Getting started with the CLI for information about installing and configuring the OpenShift Container Platform CLI. Your OpenShift Container Platform permissions must allow you to create a namespace. You must have an Internet connection to access the dependencies for the operator. To install in a OpenShift Container Platform Dedicated environment, see the following: You must have the OpenShift Container Platform Dedicated environment configured and running. You must have cluster-admin authority to the OpenShift Container Platform Dedicated environment where you are installing the engine. If you plan to create managed clusters by using the Assisted Installer that is provided with Red Hat OpenShift Container Platform, see Preparing to install with the Assisted Installer topic in the OpenShift Container Platform documentation for the requirements. 1.3.1.2. Confirm your OpenShift Container Platform installation You must have a supported OpenShift Container Platform version, including the registry and storage services, installed and working. For more information about installing OpenShift Container Platform, see the OpenShift Container Platform documentation. Verify that multicluster engine operator is not already installed on your OpenShift Container Platform cluster. The multicluster engine operator allows only one single installation on each OpenShift Container Platform cluster. Continue with the following steps if there is no installation. To ensure that the OpenShift Container Platform cluster is set up correctly, access the OpenShift Container Platform web console with the following command: See the following example output: Open the URL in your browser and check the result. If the console URL displays console-openshift-console.router.default.svc.cluster.local , set the value for openshift_master_default_subdomain when you install OpenShift Container Platform. See the following example of a URL: https://console-openshift-console.apps.new-coral.purple-chesterfield.com . You can proceed to install multicluster engine operator. 1.3.1.3. Installing from the OperatorHub web console interface Best practice: From the Administrator view in your OpenShift Container Platform navigation, install the OperatorHub web console interface that is provided with OpenShift Container Platform. Select Operators > OperatorHub to access the list of available operators, and select multicluster engine for Kubernetes operator. Click Install . On the Operator Installation page, select the options for your installation: Namespace: The multicluster engine operator engine must be installed in its own namespace, or project. By default, the OperatorHub console installation process creates a namespace titled multicluster-engine . Best practice: Continue to use the multicluster-engine namespace if it is available. If there is already a namespace named multicluster-engine , select a different namespace. Channel: The channel that you select corresponds to the release that you are installing. When you select the channel, it installs the identified release, and establishes that the future errata updates within that release are obtained. Approval strategy: The approval strategy identifies the human interaction that is required for applying updates to the channel or release to which you subscribed. Select Automatic , which is selected by default, to ensure any updates within that release are automatically applied. Select Manual to receive a notification when an update is available. If you have concerns about when the updates are applied, this might be best practice for you. Note: To upgrade to the minor release, you must return to the OperatorHub page and select a new channel for the more current release. Select Install to apply your changes and create the operator. See the following process to create the MultiClusterEngine custom resource. In the OpenShift Container Platform console navigation, select Installed Operators > multicluster engine for Kubernetes . Select the MultiCluster Engine tab. Select Create MultiClusterEngine . Update the default values in the YAML file. See options in the MultiClusterEngine advanced configuration section of the documentation. The following example shows the default template that you can copy into the editor: apiVersion: multicluster.openshift.io/v1 kind: MultiClusterEngine metadata: name: multiclusterengine spec: {} Select Create to initialize the custom resource. It can take up to 10 minutes for the multicluster engine operator engine to build and start. After the MultiClusterEngine resource is created, the status for the resource is Available on the MultiCluster Engine tab. 1.3.1.4. Installing from the OpenShift Container Platform CLI Create a multicluster engine operator engine namespace where the operator requirements are contained. Run the following command, where namespace is the name for your multicluster engine for Kubernetes operator namespace. The value for namespace might be referred to as Project in the OpenShift Container Platform environment: Switch your project namespace to the one that you created. Replace namespace with the name of the multicluster engine for Kubernetes operator namespace that you created in step 1. Create a YAML file to configure an OperatorGroup resource. Each namespace can have only one operator group. Replace default with the name of your operator group. Replace namespace with the name of your project namespace. See the following example: apiVersion: operators.coreos.com/v1 kind: OperatorGroup metadata: name: <default> namespace: <namespace> spec: targetNamespaces: - <namespace> Run the following command to create the OperatorGroup resource. Replace operator-group with the name of the operator group YAML file that you created: Create a YAML file to configure an OpenShift Container Platform Subscription. Your file should look similar to the following example: apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: name: multicluster-engine spec: sourceNamespace: openshift-marketplace source: redhat-operators channel: stable-2.6 installPlanApproval: Automatic name: multicluster-engine Note: To configure infrastructure nodes, see Configuring infrastructure nodes for multicluster engine operator . Run the following command to create the OpenShift Container Platform Subscription. Replace subscription with the name of the subscription file that you created: Create a YAML file to configure the MultiClusterEngine custom resource. Your default template should look similar to the following example: apiVersion: multicluster.openshift.io/v1 kind: MultiClusterEngine metadata: name: multiclusterengine spec: {} Note: For installing the multicluster engine operator on infrastructure nodes, see the MultiClusterEngine custom resource additional configuration section: Run the following command to create the MultiClusterEngine custom resource. Replace custom-resource with the name of your custom resource file: If this step fails with the following error, the resources are still being created and applied. Run the command again in a few minutes when the resources are created: Run the following command to get the custom resource. It can take up to 10 minutes for the MultiClusterEngine custom resource status to display as Available in the status.phase field after you run the following command: If you are reinstalling the multicluster engine operator and the pods do not start, see Troubleshooting reinstallation failure for steps to work around this problem. Notes: A ServiceAccount with a ClusterRoleBinding automatically gives cluster administrator privileges to multicluster engine operator and to any user credentials with access to the namespace where you install multicluster engine operator. 1.3.2. Configuring infrastructure nodes for multicluster engine operator Configure your OpenShift Container Platform cluster to contain infrastructure nodes to run approved multicluster engine operator management components. Running components on infrastructure nodes avoids allocating OpenShift Container Platform subscription quota for the nodes that are running multicluster engine operator management components. After adding infrastructure nodes to your OpenShift Container Platform cluster, follow the Installing from the OpenShift Container Platform CLI instructions and add the following configurations to the Operator Lifecycle Manager Subscription and MultiClusterEngine custom resource. 1.3.2.1. Configuring infrastructure nodes to the OpenShift Container Platform cluster Follow the procedures that are described in Creating infrastructure machine sets in the OpenShift Container Platform documentation. Infrastructure nodes are configured with a Kubernetes taints and labels to keep non-management workloads from running on them. To be compatible with the infrastructure node enablement provided by multicluster engine operator, ensure your infrastructure nodes have the following taints and labels applied: metadata: labels: node-role.kubernetes.io/infra: "" spec: taints: - effect: NoSchedule key: node-role.kubernetes.io/infra 1.3.2.2. Operator Lifecycle Manager subscription configuration Add the following additional configuration before applying the Operator Lifecycle Manager Subscription: spec: config: nodeSelector: node-role.kubernetes.io/infra: "" tolerations: - key: node-role.kubernetes.io/infra effect: NoSchedule operator: Exists 1.3.2.3. MultiClusterEngine custom resource additional configuration Add the following additional configuration before applying the MultiClusterEngine custom resource: spec: nodeSelector: node-role.kubernetes.io/infra: "" 1.3.3. Install on disconnected networks You might need to install the multicluster engine operator on Red Hat OpenShift Container Platform clusters that are not connected to the Internet. The procedure to install on a disconnected engine requires some of the same steps as the connected installation. Important: You must install multicluster engine operator on a cluster that does not have Red Hat Advanced Cluster Management for Kubernetes earlier than 2.5 installed. The multicluster engine operator cannot co-exist with Red Hat Advanced Cluster Management for Kubernetes on versions earlier than 2.5 because they provide some of the same management components. It is recommended that you install multicluster engine operator on a cluster that has never previously installed Red Hat Advanced Cluster Management. If you are using Red Hat Advanced Cluster Management for Kubernetes at version 2.5.0 or later then multicluster engine operator is already installed on the cluster with it. You must download copies of the packages to access them during the installation, rather than accessing them directly from the network during the installation. Prerequisites Confirm your OpenShift Container Platform installation Installing in a disconnected environment 1.3.3.1. Prerequisites You must meet the following requirements before you install The multicluster engine operator: A supported OpenShift Container Platform version must be deployed in your environment, and you must be logged in with the command line interface (CLI). You need access to catalog.redhat.com . Note: For managing bare metal clusters, you need a supported OpenShift Container Platform version. See the OpenShift Container Platform Installing . Your Red Hat OpenShift Container Platform permissions must allow you to create a namespace. You must have a workstation with Internet connection to download the dependencies for the operator. 1.3.3.2. Confirm your OpenShift Container Platform installation You must have a supported OpenShift Container Platform version, including the registry and storage services, installed and working in your cluster. For information about OpenShift Container Platform, see OpenShift Container Platform documentation . When and if you are connected, accessing the OpenShift Container Platform web console with the following command to verify: See the following example output: The console URL in this example is: https:// console-openshift-console.apps.new-coral.purple-chesterfield.com . Open the URL in your browser and check the result. If the console URL displays console-openshift-console.router.default.svc.cluster.local , set the value for openshift_master_default_subdomain when you install OpenShift Container Platform. 1.3.3.3. Installing in a disconnected environment Important: You need to download the required images to a mirroring registry to install the operators in a disconnected environment. Without the download, you might receive ImagePullBackOff errors during your deployment. Follow these steps to install the multicluster engine operator in a disconnected environment: Create a mirror registry. If you do not already have a mirror registry, create one by completing the procedure in the Disconnected installation mirroring topic of the Red Hat OpenShift Container Platform documentation. If you already have a mirror registry, you can configure and use your existing one. Note: For bare metal only, you need to provide the certificate information for the disconnected registry in your install-config.yaml file. To access the image in a protected disconnected registry, you must provide the certificate information so the multicluster engine operator can access the registry. Copy the certificate information from the registry. Open the install-config.yaml file in an editor. Find the entry for additionalTrustBundle: | . Add the certificate information after the additionalTrustBundle line. The resulting content should look similar to the following example: additionalTrustBundle: | -----BEGIN CERTIFICATE----- certificate_content -----END CERTIFICATE----- sshKey: >- Important: Additional mirrors for disconnected image registries are needed if the following Governance policies are required: Container Security Operator policy: Locate the images in the registry.redhat.io/quay source. Compliance Operator policy: Locate the images in the registry.redhat.io/compliance source. Gatekeeper Operator policy: Locate the images in the registry.redhat.io/gatekeeper source. See the following example of mirrors lists for all three operators: - mirrors: - <your_registry>/rhacm2 source: registry.redhat.io/rhacm2 - mirrors: - <your_registry>/quay source: registry.redhat.io/quay - mirrors: - <your_registry>/compliance source: registry.redhat.io/compliance Save the install-config.yaml file. Create a YAML file that contains the ImageContentSourcePolicy with the name mce-policy.yaml . Note: If you modify this on a running cluster, it causes a rolling restart of all nodes. apiVersion: operator.openshift.io/v1alpha1 kind: ImageContentSourcePolicy metadata: name: mce-repo spec: repositoryDigestMirrors: - mirrors: - mirror.registry.com:5000/multicluster-engine source: registry.redhat.io/multicluster-engine Apply the ImageContentSourcePolicy file by entering the following command: Enable the disconnected Operator Lifecycle Manager Red Hat Operators and Community Operators. the multicluster engine operator is included in the Operator Lifecycle Manager Red Hat Operator catalog. Configure the disconnected Operator Lifecycle Manager for the Red Hat Operator catalog. Follow the steps in the Using Operator Lifecycle Manager on restricted networks topic of theRed Hat OpenShift Container Platform documentation. Continue to install the multicluster engine operator for Kubernetes from the Operator Lifecycle Manager catalog. See Installing while connected online for the required steps. 1.3.4. Upgrading disconnected clusters by using policies If you have the Red Hat Advanced Cluster Management for Kubernetes hub cluster, which uses the MultiClusterHub operator to manage, upgrade, and install hub cluster components, you can use OpenShift Update Service with Red Hat Advanced Cluster Management policies to upgrade multiple clusters in a disconnected environment. OpenShift Update Service is a separate operator and operand that monitors the available versions of your managed clusters and makes them available for upgrading in a disconnected environment. OpenShift Update Service can perform the following actions: Monitor when upgrades are available for your disconnected clusters. Identify which updates are mirrored to your local site for upgrading by using the graph data file. Notify you that an upgrade is available for your cluster by using the console. Prerequisites Prepare your disconnected mirror registry Deploy the operator for OpenShift Update Service Build the graph data init container Configuring the certificate for the mirrored registry Deploy the OpenShift Update Service instance Optional: Deploying a policy to override the default registry Deploying a policy to deploy a disconnected catalog source Deploying a policy to change the managed cluster parameter Viewing available upgrades Selecting a channel Upgrading the cluster Additional resources See Configuring additional trust stores for image registry access in the OpenShift Container Platform documentation to learn more about the external registry CA certificate. 1.3.4.1. Prerequisites You must have the following prerequisites before you can use OpenShift Update Service to upgrade your disconnected clusters: You need to install Red Hat Advanced Cluster Management. See the Red Hat Advanced Cluster Management Installing and upgrading documentation. You need a hub cluster that is running on a supported Red Hat OpenShift Container Platform version with restricted OLM configured. See Using Operator Lifecycle Manager on restricted networks for details about how to configure restricted OLM. Take note of the catalog source image when you configure restricted OLM. You need an OpenShift Container Platform cluster that the hub cluster manages. You need access credentials to a local repository where you can mirror the cluster images. See Disconnected installation mirroring for more information. Note: The image for the current version of the cluster that you upgrade must remain available as one of the mirrored images. If an upgrade fails, the cluster reverts back to the version of the cluster when you tried to upgrade. 1.3.4.2. Preparing your disconnected mirror registry You must mirror both the image that you want to upgrade to and the current image that you are upgrading from to your local mirror registry. Complete the following steps to mirror the images: Create a script file with content that resembles the following example. Replace <pull-secret> with the path to your OpenShift Container Platform pull secret: UPSTREAM_REGISTRY=quay.io PRODUCT_REPO=openshift-release-dev RELEASE_NAME=ocp-release OCP_RELEASE=4.15.2-x86_64 LOCAL_REGISTRY=USD(hostname):5000 LOCAL_SECRET_JSON=<pull-secret> oc adm -a USD{LOCAL_SECRET_JSON} release mirror \ --from=USD{UPSTREAM_REGISTRY}/USD{PRODUCT_REPO}/USD{RELEASE_NAME}:USD{OCP_RELEASE} \ --to=USD{LOCAL_REGISTRY}/ocp4 \ --to-release-image=USD{LOCAL_REGISTRY}/ocp4/release:USD{OCP_RELEASE} Run the script to mirror the images, configure settings, and separate the release images from the release content. 1.3.4.3. Deploying the operator for OpenShift Update Service To deploy the operator for OpenShift Update Service in your OpenShift Container Platform environment, complete the following steps: On your hub cluster, access the OpenShift Container Platform operator hub. Deploy the operator by selecting OpenShift Update Service Operator and update the default values if needed. The deployment of the operator creates a new project named openshift-update-service . Wait for the installation of the operator to finish. You can check the status of the installation by running the oc get pods command. Verify that the operator is in the running state. 1.3.4.4. Building the graph data init container OpenShift Update Service uses graph data information to find the available upgrades. In a connected environment, OpenShift Update Service pulls the graph data information for available upgrades directly from the update-service graph data GitHub repository . In a disconnected environment, you must make the graph data available in a local repository by using an init container . Complete the following steps to create a graph data init container : Clone the graph data Git repository by running the following command: git clone https://github.com/openshift/cincinnati-graph-data Create a file that has the information for your graph data init . You can find a sample Dockerfile in the cincinnati-operator GitHub repository. The FROM value is the external registry where OpenShift Update Service finds the images. The RUN commands create the directory and package the upgrade files. The CMD command copies the package file to the local repository and extracts the files for an upgrade. Run the following command to build the graph data init container : podman build -f <docker-path> -t <graph-path>:latest Replace <docker-path> with the path to the file that you created in the step. Replace <graph-path> with the path to your local graph data init container. Run the following command to push the graph data init container : podman push <graph-path>:latest --authfile=<pull-secret>.json Replace <graph-path> with the path to your local graph data init container. Replace <pull-secret> with the path to your pull secret file. Optional: If you do not have podman installed, replace podman with docker in step three and four. 1.3.4.5. Configuring the certificate for the mirrored registry If you are using a secure external container registry to store your mirrored OpenShift Container Platform release images, OpenShift Update Service requires access to this registry to build an upgrade graph. Complete the following steps to configure your CA certificate to work with the OpenShift Update Service pod: Find the OpenShift Container Platform external registry API, which is located in image.config.openshift.io . This is where the external registry CA certificate is stored. See Configuring additional trust stores for image registry access in the additional resources section to learn more. Create a ConfigMap in the openshift-config namespace and add your CA certificate in the updateservice-registry section. See the following example: apiVersion: v1 kind: ConfigMap metadata: name: trusted-ca data: updateservice-registry: | -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- Edit the cluster resource in the image.config.openshift.io API to set the additionalTrustedCA field to the name of the ConfigMap that you created. Run the following command and replace <trusted_ca> with the path to your new ConfigMap: The OpenShift Update Service Operator watches the image.config.openshift.io API and the ConfigMap you created in the openshift-config namespace for changes, then restarts the deployment if the CA cert has changed. 1.3.4.6. Deploying the OpenShift Update Service instance When you finish deploying the OpenShift Update Service instance on your hub cluster, the instance is located where the images for the cluster upgrades are mirrored and made available to the disconnected managed cluster. Complete the following steps to deploy the instance: If you do not want to use the default namespace of the operator, navigate to Administration > Namespaces in the console to change it. In the Installed Operators section of the OpenShift Container Platform console, select OpenShift Update Service Operator . Select Create Instance in the menu. Paste the contents from your OpenShift Update Service instance. Your YAML instance might resemble the following manifest: apiVersion: update-service.openshift.io/v1beta2 kind: update-service metadata: name: openshift-cincinnati-instance namespace: openshift-update-service spec: registry: <registry-host-name>:<port> 1 replicas: 1 repository: USD{LOCAL_REGISTRY}/ocp4/release graphDataImage: '<host-name>:<port>/cincinnati-graph-data-container' 2 1 Replace with the path to your local disconnected registry for your images. 2 Replace with the path to your graph data init container. This is the same value that you used when you ran the podman push command to push your graph data init container. Select Create to create the instance. From the hub cluster CLI, enter the oc get pods command to view the status of the instance creation. It might take a few minutes. The process is complete when the result of the command shows that the instance and the operator are running. 1.3.4.7. Optional: Deploying a policy to override the default registry The following steps only apply if you have mirrored your releases into your mirrored registry. Deprecated: PlacementRule OpenShift Container Platform has a default image registry value that specifies where it finds the upgrade packages. In a disconnected environment, you can create a policy to replace that value with the path to your local image registry where you mirrored your release images. Complete the following steps to create the policy: Log in to the OpenShift Container Platform environment of your hub cluster. From the console, select Governance > Create policy . Set the YAML switch to On to view the YAML version of the policy. Delete all of the content in the YAML code. Paste the following YAML content into the window to create a custom policy: apiVersion: policy.open-cluster-management.io/v1 kind: Policy metadata: name: policy-mirror namespace: default spec: disabled: false remediationAction: enforce policy-templates: - objectDefinition: apiVersion: policy.open-cluster-management.io/v1 kind: ConfigurationPolicy metadata: name: policy-image-content-source-policy spec: object-templates: - complianceType: musthave objectDefinition: apiVersion: operator.openshift.io/v1alpha1 kind: ImageContentSourcePolicy metadata: name: <your-local-mirror-name> 1 spec: repositoryDigestMirrors: - mirrors: - <your-registry> 2 source: registry.redhat.io --- apiVersion: policy.open-cluster-management.io/v1 kind: PlacementBinding metadata: name: binding-policy-mirror namespace: default placementRef: name: placement-policy-mirror kind: PlacementRule apiGroup: apps.open-cluster-management.io subjects: - name: policy-mirror kind: Policy apiGroup: policy.open-cluster-management.io --- apiVersion: apps.open-cluster-management.io/v1 kind: PlacementRule metadata: name: placement-policy-mirror namespace: default spec: clusterConditions: - status: "True" type: ManagedClusterConditionAvailable clusterSelector: matchExpressions: [] 3 1 Replace with your local mirror name. 2 Replace with the path to your local mirror repository. You can find the path to your local mirror by running the oc adm release mirror command. 3 Selects all clusters if not specified. Select Enforce if supported . Select Create to create the policy. 1.3.4.8. Deploying a policy to deploy a disconnected catalog source You can push the Catalogsource policy to the managed cluster to change the default location from a connected location to your disconnected local registry. Complete the following steps to change the default location: In the console menu, select Governance > Create policy . Set the YAML switch to On to view the YAML version of the policy. Delete all of the content in the YAML code. Paste the following YAML content into the window to create a custom policy: apiVersion: policy.open-cluster-management.io/v1 kind: Policy metadata: name: policy-catalog namespace: default spec: disabled: false remediationAction: enforce policy-templates: - objectDefinition: apiVersion: policy.open-cluster-management.io/v1 kind: ConfigurationPolicy metadata: name: policy-catalog spec: object-templates: - complianceType: musthave objectDefinition: apiVersion: config.openshift.io/v1 kind: OperatorHub metadata: name: cluster spec: disableAllDefaultSources: true - complianceType: musthave objectDefinition: apiVersion: operators.coreos.com/v1alpha1 kind: CatalogSource metadata: name: my-operator-catalog namespace: openshift-marketplace spec: sourceType: grpc image: '<registry_host_name>:<port>/olm/redhat-operators:v1' 1 displayName: My Operator Catalog publisher: grpc --- apiVersion: policy.open-cluster-management.io/v1 kind: PlacementBinding metadata: name: binding-policy-catalog namespace: default placementRef: name: placement-policy-catalog kind: PlacementRule apiGroup: apps.open-cluster-management.io subjects: - name: policy-catalog kind: Policy apiGroup: policy.open-cluster-management.io --- apiVersion: apps.open-cluster-management.io/v1 kind: PlacementRule metadata: name: placement-policy-catalog namespace: default spec: clusterConditions: - status: "True" type: ManagedClusterConditionAvailable clusterSelector: matchExpressions: [] 2 1 Replace with the path to your local restricted catalog source image. 2 Selects all clusters if not specified. Select Enforce if supported . Select Create to create the policy. 1.3.4.9. Deploying a policy to change the managed cluster parameter You can push the ClusterVersion policy to the managed cluster to change the default location where it retrieves its upgrades. Complete the following steps: From the managed cluster, confirm that the ClusterVersion upstream parameter is currently the default public OpenShift Update Service operand by running the following command: oc get clusterversion -o yaml From the hub cluster, identify the route URL to the OpenShift Update Service operand by running the following command: oc get routes Remember the result for later. In the hub cluster console menu, select Governance > Create a policy . Set the YAML switch to On to view the YAML version of the policy. Delete all of the content in the YAML code. Paste the following YAML content into the window to create a custom policy: apiVersion: policy.open-cluster-management.io/v1 kind: Policy metadata: name: policy-cluster-version namespace: default annotations: policy.open-cluster-management.io/standards: null policy.open-cluster-management.io/categories: null policy.open-cluster-management.io/controls: null spec: disabled: false remediationAction: enforce policy-templates: - objectDefinition: apiVersion: policy.open-cluster-management.io/v1 kind: ConfigurationPolicy metadata: name: policy-cluster-version spec: object-templates: - complianceType: musthave objectDefinition: apiVersion: config.openshift.io/v1 kind: ClusterVersion metadata: name: version spec: channel: stable-4.4 upstream: >- https://example-cincinnati-policy-engine-uri/api/upgrades_info/v1/graph 1 --- apiVersion: policy.open-cluster-management.io/v1 kind: PlacementBinding metadata: name: binding-policy-cluster-version namespace: default placementRef: name: placement-policy-cluster-version kind: PlacementRule apiGroup: apps.open-cluster-management.io subjects: - name: policy-cluster-version kind: Policy apiGroup: policy.open-cluster-management.io --- apiVersion: apps.open-cluster-management.io/v1 kind: PlacementRule metadata: name: placement-policy-cluster-version namespace: default spec: clusterConditions: - status: "True" type: ManagedClusterConditionAvailable clusterSelector: matchExpressions: [] 2 1 Replace with the path to your hub cluster OpenShift Update Service operand. Selects all clusters if not specified. You can complete the following steps to determine the path to the operand: Run the oc get get routes -A command on the hub cluster. Find the route to update-service . The path to the operand is the value in the HOST/PORT field. Select Enforce if supported . Select Create to create the policy. In the managed cluster CLI, confirm that the upstream parameter in the ClusterVersion is updated with the local hub cluster OpenShift Update Service URL by running the following command: oc get clusterversion -o yaml Verify that the results resemble the following content: apiVersion: v1 items: - apiVersion: config.openshift.io/v1 kind: ClusterVersion [..] spec: channel: stable-4.4 upstream: https://<hub-cincinnati-uri>/api/upgrades_info/v1/graph 1.3.4.10. Viewing available upgrades You can view a list of available upgrades for your managed cluster by completing the following steps: From the console, select Infrastructure > Clusters . Select a cluster that is in the Ready state. From the Actions menu, select Upgrade cluster . Verify that the optional upgrade paths are available. Note: No available upgrade versions are shown if the current version is not mirrored into the local image repository. 1.3.4.11. Selecting a channel You can use the Red Hat Advanced Cluster Management console to select a channel for your cluster upgrades on OpenShift Container Platform. Those versions must be available on the mirror registry. Complete the steps in Selecting a channel to specify a channel for your upgrades. 1.3.4.12. Upgrading the cluster After configuring the disconnected registry, Red Hat Advanced Cluster Management and OpenShift Update Service use the disconnected registry to find if upgrades are available. If no available upgrades are displayed, make sure that you have the release image of the current level of the cluster and at least one later level mirrored in the local repository. If the release image for the current version of the cluster is not available, no upgrades are available. Complete the following steps to upgrade: In the console, select Infrastructure > Clusters . Find the cluster that you want to choose if there is an available upgrade. If there is an upgrade available, the Distribution version column for the cluster shows an upgrade available. Select the Options menu for the cluster, and select Upgrade cluster . Select the target version for the upgrade, and select Upgrade . If your cluster upgrade fails, the Operator generally retries the upgrade a few times, stops, and reports the status of the failing component. In some cases, the upgrade process continues to cycle through attempts to complete the process. Rolling your cluster back to a version after a failed upgrade is not supported. Contact Red Hat support for assistance if your cluster upgrade fails. 1.3.4.12.1. Additional resources See Configuring additional trust stores for image registry access in the OpenShift Container Platform documentation to learn more about the external registry CA certificate. 1.3.5. Advanced configuration The multicluster engine operator is installed using an operator that deploys all of the required components. The multicluster engine operator can be further configured during or after installation. Learn more about the advanced configuration options. 1.3.5.1. Deployed components Add one or more of the following attributes to the MultiClusterEngine custom resource: Table 1.3. Table list of the deployed components Name Description Enabled assisted-service Installs OpenShift Container Platform with minimal infrastructure prerequisites and comprehensive pre-flight validations True cluster-lifecycle Provides cluster management capabilities for OpenShift Container Platform and Kubernetes hub clusters True cluster-manager Manages various cluster-related operations within the cluster environment True cluster-proxy-addon Automates the installation of apiserver-network-proxy on both hub and managed clusters using a reverse proxy server True console-mce Enables the multicluster engine operator console plug-in True discovery Discovers and identifies new clusters within the OpenShift Cluster Manager True hive Provisions and performs initial configuration of OpenShift Container Platform clusters True hypershift Hosts OpenShift Container Platform control planes at scale with cost and time efficiency, and cross-cloud portability True hypershift-local-hosting Enables local hosting capabilities for within the local cluster environment True local-cluster Enables the import and self-management of the local hub cluster where the multicluster engine operator is deployed True managedserviceacccount Synchronizes service accounts to managed clusters, and collects tokens as secret resources to give back to the hub cluster True server-foundation Provides foundational services for server-side operations within the multicluster environment True When you install multicluster engine operator on to the cluster, not all of the listed components are enabled by default. You can further configure multicluster engine operator during or after installation by adding one or more attributes to the MultiClusterEngine custom resource. Continue reading for information about the attributes that you can add. 1.3.5.2. Console and component configuration The following example displays the spec.overrides default template that you can use to enable or disable the component: apiVersion: operator.open-cluster-management.io/v1 kind: MultiClusterEngine metadata: name: multiclusterengine spec: overrides: components: - name: <name> 1 enabled: true Replace name with the name of the component. Alternatively, you can run the following command. Replace namespace with the name of your project and name with the name of the component: 1.3.5.3. Local-cluster enablement By default, the cluster that is running multicluster engine operator manages itself. To install multicluster engine operator without the cluster managing itself, specify the following values in the spec.overrides.components settings in the MultiClusterEngine section: apiVersion: multicluster.openshift.io/v1 kind: MultiClusterEngine metadata: name: multiclusterengine spec: overrides: components: - name: local-cluster enabled: false The name value identifies the hub cluster as a local-cluster . The enabled setting specifies whether the feature is enabled or disabled. When the value is true , the hub cluster manages itself. When the value is false , the hub cluster does not manage itself. A hub cluster that is managed by itself is designated as the local-cluster in the list of clusters. 1.3.5.4. Custom image pull secret If you plan to import Kubernetes clusters that were not created by OpenShift Container Platform or the multicluster engine operator, generate a secret that contains your OpenShift Container Platform pull secret information to access the entitled content from the distribution registry. The secret requirements for OpenShift Container Platform clusters are automatically resolved by OpenShift Container Platform and multicluster engine for Kubernetes operator, so you do not have to create the secret if you are not importing other types of Kubernetes clusters to be managed. Important: These secrets are namespace-specific, so make sure that you are in the namespace that you use for your engine. Download your OpenShift Container Platform pull secret file from cloud.redhat.com/openshift/install/pull-secret by selecting Download pull secret . Your OpenShift Container Platform pull secret is associated with your Red Hat Customer Portal ID, and is the same across all Kubernetes providers. Run the following command to create your secret: Replace secret with the name of the secret that you want to create. Replace namespace with your project namespace, as the secrets are namespace-specific. Replace path-to-pull-secret with the path to your OpenShift Container Platform pull secret that you downloaded. The following example displays the spec.imagePullSecret template to use if you want to use a custom pull secret. Replace secret with the name of your pull secret: apiVersion: multicluster.openshift.io/v1 kind: MultiClusterEngine metadata: name: multiclusterengine spec: imagePullSecret: <secret> 1.3.5.5. Target namespace The operands can be installed in a designated namespace by specifying a location in the MultiClusterEngine custom resource. This namespace is created upon application of the MultiClusterEngine custom resource. Important: If no target namespace is specified, the operator will install to the multicluster-engine namespace and will set it in the MultiClusterEngine custom resource specification. The following example displays the spec.targetNamespace template that you can use to specify a target namespace. Replace target with the name of your destination namespace. Note: The target namespace cannot be the default namespace: apiVersion: multicluster.openshift.io/v1 kind: MultiClusterEngine metadata: name: multiclusterengine spec: targetNamespace: <target> 1.3.5.6. availabilityConfig The hub cluster has two availabilities: High and Basic . By default, the hub cluster has an availability of High , which gives hub cluster components a replicaCount of 2 . This provides better support in cases of failover but consumes more resources than the Basic availability, which gives components a replicaCount of 1 . Important: Set spec.availabilityConfig to Basic if you are using multicluster engine operator on a single-node OpenShift cluster. The following examples shows the spec.availabilityConfig template with Basic availability: apiVersion: multicluster.openshift.io/v1 kind: MultiClusterEngine metadata: name: multiclusterengine spec: availabilityConfig: "Basic" 1.3.5.7. nodeSelector You can define a set of node selectors in the MultiClusterEngine to install to specific nodes on your cluster. The following example shows spec.nodeSelector to assign pods to nodes with the label node-role.kubernetes.io/infra : spec: nodeSelector: node-role.kubernetes.io/infra: "" To define a set of node selectors for the Red Hat Advanced Cluster Management hub cluster, see nodeSelector in the product documentation. 1.3.5.8. tolerations You can define a list of tolerations to allow the MultiClusterEngine to tolerate specific taints defined on the cluster. The following example shows a spec.tolerations that matches a node-role.kubernetes.io/infra taint: spec: tolerations: - key: node-role.kubernetes.io/infra effect: NoSchedule operator: Exists The infra-node toleration is set on pods by default without specifying any tolerations in the configuration. Customizing tolerations in the configuration will replace this default behavior. To define a list of tolerations for the Red Hat Advanced Cluster Management hub cluster, see tolerations in the product documentation. 1.3.5.9. ManagedServiceAccount add-on The ManagedServiceAccount add-on allows you to create or delete a service account on a managed cluster. To install with this add-on enabled, include the following in the MultiClusterEngine specification in spec.overrides : apiVersion: multicluster.openshift.io/v1 kind: MultiClusterEngine metadata: name: multiclusterengine spec: overrides: components: - name: managedserviceaccount enabled: true The ManagedServiceAccount add-on can be enabled after creating MultiClusterEngine by editing the resource on the command line and setting the managedserviceaccount component to enabled: true . Alternatively, you can run the following command and replace <multiclusterengine-name> with the name of your MultiClusterEngine resource. 1.3.6. Uninstalling When you uninstall multicluster engine for Kubernetes operator, you see two different levels of the process: A custom resource removal and a complete operator uninstall . It might take up to five minutes to complete the uninstall process. The custom resource removal is the most basic type of uninstall that removes the custom resource of the MultiClusterEngine instance but leaves other required operator resources. This level of uninstall is helpful if you plan to reinstall using the same settings and components. The second level is a more complete uninstall that removes most operator components, excluding components such as custom resource definitions. When you continue with this step, it removes all of the components and subscriptions that were not removed with the custom resource removal. After this uninstall, you must reinstall the operator before reinstalling the custom resource. 1.3.6.1. Prerequisite: Detach enabled services Before you uninstall the multicluster engine for Kubernetes operator, you must detach all of the clusters that are managed by that engine. To avoid errors, detach all clusters that are still managed by the engine, then try to uninstall again. If you have managed clusters attached, you might see the following message. For more information about detaching clusters, see the Removing a cluster from management section by selecting the information for your provider in Cluster creation introduction . 1.3.6.2. Removing resources by using commands If you have not already. ensure that your OpenShift Container Platform CLI is configured to run oc commands. See Getting started with the OpenShift CLI in the OpenShift Container Platform documentation for more information about how to configure the oc commands. Change to your project namespace by entering the following command. Replace namespace with the name of your project namespace: Enter the following command to remove the MultiClusterEngine custom resource: You can view the progress by entering the following command: Enter the following commands to delete the multicluster-engine ClusterServiceVersion in the namespace it is installed in: The CSV version shown here may be different. 1.3.6.3. Deleting the components by using the console When you use the RedHat OpenShift Container Platform console to uninstall, you remove the operator. Complete the following steps to uninstall by using the console: In the OpenShift Container Platform console navigation, select Operators > Installed Operators > multicluster engine for Kubernetes . Remove the MultiClusterEngine custom resource. Select the tab for Multiclusterengine . Select the Options menu for the MultiClusterEngine custom resource. Select Delete MultiClusterEngine . Run the clean-up script according to the procedure in the following section. Tip: If you plan to reinstall the same multicluster engine for Kubernetes operator version, you can skip the rest of the steps in this procedure and reinstall the custom resource. Navigate to Installed Operators . Remove the _ multicluster engine for Kubernetes_ operator by selecting the Options menu and selecting Uninstall operator . 1.3.6.4. Troubleshooting Uninstall If the multicluster engine custom resource is not being removed, remove any potential remaining artifacts by running the clean-up script. Copy the following script into a file: See Disconnected installation mirroring for more information. 1.4. Red Hat Advanced Cluster Management integration If you are using multicluster engine operator with Red Hat Advanced Cluster Management installed, you can access more multicluster management features, such as Observability and Policy . For integrated capability, see the following requirements: Install Red Hat Advanced Cluster Management. See the Red Hat Advanced Cluster Management Installing and upgrading documentation. See MultiClusterHub advanced configuration for details about Red Hat Advanced Cluster Management after you install. See the following procedures for multicluster engine operator and Red Hat Advanced Cluster Management multicluster management: Discovering multicluster engine operator hosted clusters in Red Hat Advanced Cluster Management Automating import for discovered hosted clusters Automating import for discovered OpenShift Service on AWS clusters Observability integration 1.4.1. Discovering multicluster engine operator hosted clusters in Red Hat Advanced Cluster Management If you have multicluster engine operator clusters that are hosting multiple hosted clusters , you can bring those hosted clusters to a Red Hat Advanced Cluster Management hub cluster to manage with Red Hat Advanced Cluster Management management components, such as Application lifecycle and Governance . You can have those hosted clusters automatically discovered and imported as managed clusters. Note: Since the hosted control planes run on the managed multicluster engine operator cluster nodes, the number of hosted control planes that the cluster can host is determined by the resource availability of managed multicluster engine operator cluster nodes, as well as the number of managed multicluster engine operator clusters. You can add more nodes or managed clusters to host more hosted control planes. Required access: Cluster administrator Prerequisites Configuring Red Hat Advanced Cluster Management to import multicluster engine operator clusters Importing multicluster engine operator manually Discovering hosted clusters from multicluster engine operator 1.4.1.1. Prerequisites You need one or more multicluster engine operator clusters. You need a Red Hat Advanced Cluster Management cluster set as your hub cluster. Install the clusteradm CLI by running the following command: curl -L https://raw.githubusercontent.com/open-cluster-management-io/clusteradm/main/install.sh | bash 1.4.1.2. Configuring Red Hat Advanced Cluster Management to import multicluster engine operator clusters multicluster engine operator has a local-cluster , which is a hub cluster that is managed. The following default addons are enabled for this local-cluster in the open-cluster-management-agent-addon namespace: cluster-proxy managed-serviceaccount work-manager 1.4.1.2.1. Configuring add-ons When your multicluster engine operator is imported into Red Hat Advanced Cluster Management, Red Hat Advanced Cluster Management enables the same set of add-ons to manage the multicluster engine operator. Install those add-ons in a different multicluster engine operator namespace so that the multicluster engine operator can self-manage with the local-cluster add-ons while Red Hat Advanced Cluster Management manages multicluster engine operator at the same time. Complete the following procedure: Log in to your Red Hat Advanced Cluster Management with the CLI. Create the addonDeploymentConfig resource to specify a different add-on installation namespace. See the following example where agentInstallNamespace points to open-cluster-management-agent-addon-discovery : apiVersion: addon.open-cluster-management.io/v1alpha1 kind: addonDeploymentConfig metadata: name: addon-ns-config namespace: multicluster-engine spec: agentInstallNamespace: open-cluster-management-agent-addon-discovery Run oc apply -f <filename>.yaml to apply the file. Update the existing ClusterManagementAddOn resources for the add-ons so that the add-ons are installed in the open-cluster-management-agent-addon-discovery namespace that is specified in the addonDeploymentConfig resource that you created. See the following example with open-cluster-management-global-set as the namespace: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: ClusterManagementAddOn metadata: name: work-manager spec: addonMeta: displayName: work-manager installStrategy: placements: - name: global namespace: open-cluster-management-global-set rolloutStrategy: type: All type: Placements Add the addonDeploymentConfigs to the ClusterManagementAddOn . See the following example: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: ClusterManagementAddOn metadata: name: work-manager spec: addonMeta: displayName: work-manager installStrategy: placements: - name: global namespace: open-cluster-management-global-set rolloutStrategy: type: All configs: - group: addon.open-cluster-management.io name: addon-ns-config namespace: multicluster-engine resource: addondeploymentconfigs type: Placements Add the addonDeploymentConfig to the managed-serviceaccount . See the following example: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: ClusterManagementAddOn metadata: name: managed-serviceaccount spec: addonMeta: displayName: managed-serviceaccount installStrategy: placements: - name: global namespace: open-cluster-management-global-set rolloutStrategy: type: All configs: - group: addon.open-cluster-management.io name: addon-ns-config namespace: multicluster-engine resource: addondeploymentconfigs type: Placements Add the addondeploymentconfigs value to the ClusterManagementAddOn resource named, cluster-proxy . See the following example: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: ClusterManagementAddOn metadata: name: cluster-proxy spec: addonMeta: displayName: cluster-proxy installStrategy: placements: - name: global namespace: open-cluster-management-global-set rolloutStrategy: type: All configs: - group: addon.open-cluster-management.io name: addon-ns-config namespace: multicluster-engine resource: addondeploymentconfigs type: Placements Run the following command to verify that the add-ons for the Red Hat Advanced Cluster Management local-cluster are re-installed into the namespace that you specified: oc get deployment -n open-cluster-management-agent-addon-discovery See the following output example: NAME READY UP-TO-DATE AVAILABLE AGE cluster-proxy-proxy-agent 1/1 1 1 24h klusterlet-addon-workmgr 1/1 1 1 24h managed-serviceaccount-addon-agent 1/1 1 1 24h 1.4.1.2.2. Creating a KlusterletConfig resource multicluster engine operator has a local-cluster, which is a hub cluster that is managed. A resource named klusterlet is created for this local-cluster. When your multicluster engine operator is imported into Red Hat Advanced Cluster Management, Red Hat Advanced Cluster Management installs the klusterlet with the same name, klusterlet , to manage the multicluster engine operator. This conflicts with the multicluster engine operator local-cluster klusterlet. You need to create a KlusterletConfig resource that is used by ManagedCluster resources to import multicluster engine operator clusters so that the klusterlet is installed with a different name to avoid the conflict. Complete the following procedure: Create a KlusterletConfig resource using the following example. When this KlusterletConfig resource is referenced in a managed cluster, the value in the spec.installMode.noOperator.postfix field is used as a suffix to the klusterlet name, such as klusterlet-mce-import : kind: KlusterletConfig apiVersion: config.open-cluster-management.io/v1alpha1 metadata: name: mce-import-klusterlet-config spec: installMode: type: noOperator noOperator: postfix: mce-import Run oc apply -f <filename>.yaml to apply the file. 1.4.1.2.3. Configure for backup and restore Since you installed Red Hat Advanced Cluster Management, you can also use the Backup and restore feature. If the hub cluster is restored in a disaster recovery scenario, the imported multicluster engine operator clusters and hosted clusters are imported to the newer Red Hat Advanced Cluster Management hub cluster. In this scenario, you need to restore the configurations as part of Red Hat Advanced Cluster Management hub cluster restore. Add the backup=true label to enable backup. See the following steps for each add-on: For your addon-ns-config , run the following command: oc label addondeploymentconfig addon-ns-config -n multicluster-engine cluster.open-cluster-management.io/backup=true For your hypershift-addon-deploy-config , run the following command: oc label addondeploymentconfig hypershift-addon-deploy-config -n multicluster-engine cluster.open-cluster-management.io/backup=true For your work-manager , run the following command: oc label clustermanagementaddon work-manager cluster.open-cluster-management.io/backup=true For your `cluster-proxy `, run the following command: oc label clustermanagementaddon cluster-proxy cluster.open-cluster-management.io/backup=true For your managed-serviceaccount , run the following command: oc label clustermanagementaddon managed-serviceaccount cluster.open-cluster-management.io/backup=true For your mce-import-klusterlet-config , run the following command: oc label KlusterletConfig mce-import-klusterlet-config cluster.open-cluster-management.io/backup=true 1.4.1.3. Importing multicluster engine operator manually To manually import an multicluster engine operator cluster from your Red Hat Advanced Cluster Management cluster, complete the following procedure: From your Red Hat Advanced Cluster Management cluster, create a ManagedCluster resource manually to import an multicluster engine operator cluster. See the following file example: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: annotations: agent.open-cluster-management.io/klusterlet-config: mce-import-klusterlet-config 1 labels: cloud: auto-detect vendor: auto-detect name: mce-a 2 spec: hubAcceptsClient: true leaseDurationSeconds: 60 1 1 The mce-import-klusterlet-config annotation references the KlusterletConfig resource that you created in the step to install the Red Hat Advanced Cluster Management klusterlet with a different name in multicluster engine operator. 2 The example imports an multicluster engine operator managed cluster named mce-a . Run oc apply -f <filename>.yaml to apply the file. Create the auto-import-secret secret that references the kubeconfig of the multicluster engine operator cluster. Go to Importing a cluster by using the auto import secret to add the auto import secret to complete the multicluster engine operator auto-import process. After you create the auto import secret in the multicluster engine operator managed cluster namespace in the Red Hat Advanced Cluster Management cluster, the managed cluster is registered. Run the following command to get the status: oc get managedcluster See following example output with the status and example URLs of managed clusters: NAME HUB ACCEPTED MANAGED CLUSTER URLS JOINED AVAILABLE AGE local-cluster true https://<api.acm-hub.com:port> True True 44h mce-a true https://<api.mce-a.com:port> True True 27s Important: Do not enable any other Red Hat Advanced Cluster Management add-ons for the imported multicluster engine operator. 1.4.1.4. Discovering hosted clusters After all your multicluster engine operator clusters are imported into Red Hat Advanced Cluster Management, you need to enable the hypershift-addon for those managed multicluster engine operator clusters to discover the hosted clusters. Default add-ons are installed into a different namespace in the procedures. Similarly, you install the hypershift-addon into a different namespace in multicluster engine operator so that the add-ons agent for multicluster engine operator local-cluster and the agent for Red Hat Advanced Cluster Management can work in multicluster engine operator. Important: For all the following commands, replace <managed-cluster-names> with comma-separated managed cluster names for multicluster engine operator. Run the following command to set the agentInstallNamespace namespace of the add-on to open-cluster-management-agent-addon-discovery : oc patch addondeploymentconfig hypershift-addon-deploy-config -n multicluster-engine --type=merge -p '{"spec":{"agentInstallNamespace":"open-cluster-management-agent-addon-discovery"}}' Run the following command to disable metrics and to disable the HyperShift operator management: oc patch addondeploymentconfig hypershift-addon-deploy-config -n multicluster-engine --type=merge -p '{"spec":{"customizedVariables":[{"name":"disableMetrics","value": "true"},{"name":"disableHOManagement","value": "true"}]}}' Run the following command to enable the hypershift-addon for multicluster engine operator: clusteradm addon enable --names hypershift-addon --clusters <managed-cluster-names> You can get the multicluster engine operator managed cluster names by running the following command in Red Hat Advanced Cluster Management. oc get managedcluster Log into multicluster engine operator clusters and verify that the hypershift-addon is installed in the namespace that you specified. Run the following command: oc get deployment -n open-cluster-management-agent-addon-discovery See the following example output that lists the add-ons: NAME READY UP-TO-DATE AVAILABLE AGE cluster-proxy-proxy-agent 1/1 1 1 24h klusterlet-addon-workmgr 1/1 1 1 24h hypershift-addon-agent 1/1 1 1 24h managed-serviceaccount-addon-agent 1/1 1 1 24h Red Hat Advanced Cluster Management deploys the hypershift-addon , which is the discovery agent that discovers hosted clusters from multicluster engine operator. The agent creates the corresponding DiscoveredCluster custom resource in the multicluster engine operator managed cluster namespace in the Red Hat Advanced Cluster Management hub cluster when the hosted cluster kube-apiserver becomes available. You can view your discovered clusters in the console. Log into hub cluster console and navigate to All Clusters > Infrastructure > Clusters . Find the Discovered clusters tab to view all discovered hosted clusters from multicluster engine operator with type MultiClusterEngineHCP . , visit Automating import for discovered hosted clusters to learn how to automatically import clusters. 1.4.2. Automating import for discovered hosted clusters Automate the import of hosted clusters by using the DiscoveredCluster resource for faster cluster management, without manually importing individual clusters. When you automatically import a discovered hosted cluster into Red Hat Advanced Cluster Management, all Red Hat Advanced Cluster Management add-ons are enabled so that you can start managing the hosted clusters with the available management tools. The hosted cluster is also auto-imported into multicluster engine operator. Through the multicluster engine operator console, you can manage the hosted cluster lifecycle. However, you cannot manage the hosted cluster lifecycle from the Red Hat Advanced Cluster Management console. Required access: Cluster administrator Prerequisites Configure settings for automatic import Creating the placement definition Binding the import policy to a placement definition 1.4.2.1. Prerequisites You need Red Hat Advanced Cluster Management installed. See the Red Hat Advanced Cluster Management Installing and upgrading documentation. You need to learn about Policies . See the introduction to Governance in the Red Hat Advanced Cluster Management documentation. 1.4.2.2. Configuring settings for automatic import Discovered hosted clusters from managed multicluster engine operator clusters are represented in DiscoveredCluster custom resources, which are located in the managed multicluster engine operator cluster namespace in Red Hat Advanced Cluster Management. See the following DiscoveredCluster resource and namespace example: apiVersion: discovery.open-cluster-management.io/v1 kind: DiscoveredCluster metadata: creationTimestamp: "2024-05-30T23:05:39Z" generation: 1 labels: hypershift.open-cluster-management.io/hc-name: hosted-cluster-1 hypershift.open-cluster-management.io/hc-namespace: clusters name: hosted-cluster-1 namespace: mce-1 resourceVersion: "1740725" uid: b4c36dca-a0c4-49f9-9673-f561e601d837 spec: apiUrl: https://a43e6fe6dcef244f8b72c30426fb6ae3-ea3fec7b113c88da.elb.us-west-1.amazonaws.com:6443 cloudProvider: aws creationTimestamp: "2024-05-30T23:02:45Z" credential: {} displayName: mce-1-hosted-cluster-1 importAsManagedCluster: false isManagedCluster: false name: hosted-cluster-1 openshiftVersion: 0.0.0 status: Active type: MultiClusterEngineHCP These discovered hosted clusters are not automatically imported into Red Hat Advanced Cluster Management until the spec.importAsManagedCluster field is set to true . Learn how to use a Red Hat Advanced Cluster Management policy to automatically set this field to true for all type.MultiClusterEngineHCP within DiscoveredCluster resources so that discovered hosted clusters are immediately automatically imported into Red Hat Advanced Cluster Management. Configure your Policy to import all your discovered hosted clusters automatically. Log in to your hub cluster from the CLI to complete the following procedure: Create a YAML file for your DiscoveredCluster custom resource and edit the configuration that is referenced in the following example: apiVersion: policy.open-cluster-management.io/v1 kind: Policy metadata: name: policy-mce-hcp-autoimport namespace: open-cluster-management-global-set annotations: policy.open-cluster-management.io/standards: NIST SP 800-53 policy.open-cluster-management.io/categories: CM Configuration Management policy.open-cluster-management.io/controls: CM-2 Baseline Configuration policy.open-cluster-management.io/description: Discovered clusters that are of type MultiClusterEngineHCP can be automatically imported into ACM as managed clusters.

Run oc apply -f <filename>.yaml -n <namespace> to apply the file. 1.4.2.3. Creating the placement definition You need to create a placement definition that specifies the managed cluster for the policy deployment. Complete the following procedure: Create the Placement definition that selects only the local-cluster , which is a hub cluster that is managed. Use the following YAML sample: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: policy-mce-hcp-autoimport-placement namespace: open-cluster-management-global-set spec: tolerations: - key: cluster.open-cluster-management.io/unreachable operator: Exists - key: cluster.open-cluster-management.io/unavailable operator: Exists clusterSets: - global predicates: - requiredClusterSelector: labelSelector: matchExpressions: - key: local-cluster operator: In values: - "true" Run oc apply -f placement.yaml -n <namespace> , where namespace matches the namespace that you used for the policy that you previously created. 1.4.2.4. Binding the import policy to a placement definition After you create the policy and the placement, you need to connect the two resources. Complete the following steps: Connect the resources by using a PlacementBinding resource. See the following example where placementRef points to the Placement that you created, and subjects points to the Policy that you created: apiVersion: policy.open-cluster-management.io/v1 kind: PlacementBinding metadata: name: policy-mce-hcp-autoimport-placement-binding namespace: open-cluster-management-global-set placementRef: name: policy-mce-hcp-autoimport-placement apiGroup: cluster.open-cluster-management.io kind: Placement subjects: - name: policy-mce-hcp-autoimport apiGroup: policy.open-cluster-management.io kind: Policy To verify, run the following command: oc get policy policy-mce-hcp-autoimport -n <namespace> Important: You can detach a hosted cluster from Red Hat Advanced Cluster Management by using the Detach option in the Red Hat Advanced Cluster Management console, or by removing the corresponding ManagedCluster custom resource from the command line. For best results, detach the managed hosted cluster before destroying the hosted cluster. When a discovered cluster is detached, the following annotation is added to the DiscoveredCluster resource to prevent the policy to import the discovered cluster again. annotations: discovery.open-cluster-management.io/previously-auto-imported: "true" If you want the detached discovered cluster to be reimported, remove this annotation. 1.4.3. Automating import for discovered OpenShift Service on AWS clusters Automate the import of OpenShift Service on AWS clusters by using Red Hat Advanced Cluster Management policy enforcement for faster cluster management, without manually importing individual clusters.

The rosa-filter has no value by default, so the filter does not restrict cluster names without a subset value. Run oc apply -f <filename>.yaml -n <namespace> to apply the file. 1.4.3.3. Creating the placement definition You need to create a placement definition that specifies the managed cluster for the policy deployment. Create the placement definition that selects only the local-cluster , which is a hub cluster that is managed. Use the following YAML sample: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement-openshift-plus-hub spec: predicates: - requiredClusterSelector: labelSelector: matchExpressions: - key: name operator: In values: - local-cluster Run oc apply -f placement.yaml -n <namespace> , where namespace matches the namespace that you used for the policy that you previously created. 1.4.3.4. Binding the import policy to a placement definition After you create the policy and the placement, you need to connect the two resources. Connect the resources by using a PlacementBinding . See the following example where placementRef points to the Placement that you created, and subjects points to the Policy that you created: apiVersion: policy.open-cluster-management.io/v1 kind: PlacementBinding metadata: name: binding-policy-rosa-autoimport placementRef: apiGroup: cluster.open-cluster-management.io kind: Placement name: placement-policy-rosa-autoimport subjects: - apiGroup: policy.open-cluster-management.io kind: Policy name: policy-rosa-autoimport To verify, run the following command: 1.4.4. Observability integration With the Red Hat Advanced Cluster Management Observability feature, you can view health and utilization of clusters across your fleet. You can install Red Hat Advanced Cluster Management and enable Observability. 1.4.4.1. Observing hosted control planes After you enable the multicluster-observability pod, you can use Red Hat Advanced Cluster Management Observability Grafana dashboards to view the following information about your hosted control planes: ACM > Hosted Control Planes Overview dashboard to see cluster capacity estimates for hosting hosted control planes, the related cluster resources, and the list and status of existing hosted control planes. ACM > Resources > Hosted Control Plane dashboard that you can access from the Overview page to see the resource utilizations of the selected hosted control plane. To enable, see Observability service . 1.5. Managing credentials A credential is required to create and manage a Red Hat OpenShift Container Platform cluster on a cloud service provider with multicluster engine operator. The credential stores the access information for a cloud provider. Each provider account requires its own credential, as does each domain on a single provider. You can create and manage your cluster credentials. Credentials are stored as Kubernetes secrets. Secrets are copied to the namespace of a managed cluster so that the controllers for the managed cluster can access the secrets. When a credential is updated, the copies of the secret are automatically updated in the managed cluster namespaces. Note: Changes to the pull secret, SSH keys, or base domain of the cloud provider credentials are not reflected for existing managed clusters, as they have already been provisioned using the original credentials. Required access: Edit Creating a credential for Amazon Web Services Creating a credential for Microsoft Azure Creating a credential for Google Cloud Platform Creating a credential for VMware vSphere Creating a credential for Red Hat OpenStack Platform Creating a credential for Red Hat OpenShift Cluster Manager Creating a credential for Ansible Automation Platform Creating a credential for an on-premises environment 1.5.1.

Managing a credential by using the console To create a credential from the multicluster engine operator console, complete the steps in the console. Start at the navigation menu. Click Credentials to choose from existing credential options. Tip: Create a namespace specifically to host your credentials, both for convenience and added security. You can optionally add a Base DNS domain for your credential. If you add the base DNS domain to the credential, it is automatically populated in the correct field when you create a cluster with this credential. See the following steps: Add your AWS access key ID for your AWS account. See Log in to AWS to find your ID. Provide the contents for your new AWS Secret Access Key . If you want to enable a proxy, enter the proxy information: HTTP proxy URL: The URL that should be used as a proxy for HTTP traffic. HTTPS proxy URL: The secure proxy URL that should be used for HTTPS traffic. If no value is provided, the same value as the HTTP Proxy URL is used for both HTTP and HTTPS . No proxy domains: A comma-separated list of domains that should bypass the proxy. Begin a domain name with a period . to include all of the subdomains that are in that domain. Add an asterisk * to bypass the proxy for all destinations. Additional trust bundle: One or more additional CA certificates that are required for proxying HTTPS connections. Enter your Red Hat OpenShift pull secret. See Download your Red Hat OpenShift pull secret to download your pull secret. Add your SSH private key and SSH public key , which allows you to connect to the cluster. You can use an existing key pair, or create a new one with key generation program. You can create a cluster that uses this credential by completing the steps in Creating a cluster on Amazon Web Services or Creating a cluster on Amazon Web Services GovCloud . You can edit your credential in the console. If the cluster was created by using this provider connection, then the <cluster-name>-aws-creds> secret from <cluster-namespace> will get updated with the new credentials. Note: Updating credentials does not work for cluster pool claimed clusters. When you are no longer managing a cluster that is using a credential, delete the credential to protect the information in the credential. Select Actions to delete in bulk, or select the options menu beside the credential that you want to delete. 1.5.1.2.1.

Cluster lifecycle introduction The multicluster engine operator is the cluster lifecycle operator that provides cluster management capabilities for OpenShift Container Platform and Red Hat Advanced Cluster Management hub clusters. The multicluster engine operator is a software operator that enhances cluster fleet management and supports OpenShift Container Platform cluster lifecycle management across clouds and data centers. You can use multicluster engine operator with or without Red Hat Advanced Cluster Management. Red Hat Advanced Cluster Management also installs multicluster engine operator automatically and offers further multicluster capabilities. See the following documentation: Cluster lifecycle architecture Managing credentials overview Release images Specifying Release images Maintaining a custom list of release images while connected Maintaining a custom list of release images while disconnected Host inventory introduction Creating clusters Creating a cluster with the CLI Configuring additional manifests during cluster creation Creating a cluster on Amazon Web Services Creating a cluster on Amazon Web Services GovCloud Creating a cluster on Microsoft Azure Creating a cluster on Google Cloud Platform Creating a cluster on VMware vSphere Creating a cluster on Red Hat OpenStack Platform Creating a cluster in an on-premise environment Creating a cluster in a proxy environment Cluster import Importing a managed cluster by using the console Importing a managed cluster by using the CLI Specifying image registry on managed clusters for import Accessing your cluster Scaling managed clusters Hibernating a created cluster Upgrading your cluster Upgrading a disconnected cluster Enabling cluster proxy add-ons Configuring Ansible Automation Platform tasks to run on managed clusters ClusterClaims List existing ClusterClaims Create custom ClusterClaims ManagedClusterSets Creating a ManagedClusterSet Assigning RBAC permissions to a ManagedClusterSet Creating a ManagedClusterSetBinding resource Placing managed clusters by using taints and tolerations Removing a managed cluster from a ManagedClusterSet Placement Managing cluster pools (Technology Preview) Creating a cluster pool Claiming clusters from cluster pools Updating the cluster pool release image Scaling cluster pools Destroying a cluster pool Enabling ManagedServiceAccount Cluster lifecycle advanced configuration Removing a cluster from management 1.6.1. Cluster lifecycle architecture Cluster lifecycle requires two types of clusters: hub clusters and managed clusters . The hub cluster is the OpenShift Container Platform (or Red Hat Advanced Cluster Management) main cluster with the multicluster engine operator automatically installed. You can create, manage, and monitor other Kubernetes clusters with the hub cluster. You can create clusters by using the hub cluster, while you can also import existing clusters to be managed by the hub cluster. When you create a managed cluster, the cluster is created using the Red Hat OpenShift Container Platform cluster installer with the Hive resource. You can find more information about the process of installing clusters with the OpenShift Container Platform installer by reading Installing and configuring OpenShift Container Platform clusters in the OpenShift Container Platform documentation. The following diagram shows the components that are installed with the multicluster engine for Kubernetes operator for cluster management: The components of the cluster lifecycle management architecture include the following items: 1.6.1.1. Hub cluster The managed cluster import controller deploys the klusterlet operator to the managed clusters. The Hive controller provisions the clusters that you create by using the multicluster engine for Kubernetes operator. The Hive Controller also destroys managed clusters that were created by the multicluster engine for Kubernetes operator. The cluster curator controller creates the Ansible jobs as the pre-hook or post-hook to configure the cluster infrastructure environment when creating or upgrading managed clusters. When a managed cluster add-on is enabled on the hub cluster, its add-on hub controller is deployed on the hub cluster. The add-on hub controller deploys the add-on agent to the managed clusters. 1.6.1.2. Managed cluster The klusterlet operator deploys the registration and work controllers on the managed cluster. The Registration Agent registers the managed cluster and the managed cluster add-ons with the hub cluster. The Registration Agent also maintains the status of the managed cluster and the managed cluster add-ons. The following permissions are automatically created within the Clusterrole to allow the managed cluster to access the hub cluster: Allows the agent to get or update its owned cluster that the hub cluster manages Allows the agent to update the status of its owned cluster that the hub cluster manages Allows the agent to rotate its certificate Allows the agent to get or update the coordination.k8s.io lease Allows the agent to get its managed cluster add-ons Allows the agent to update the status of its managed cluster add-ons The work agent applies the Add-on Agent to the managed cluster. The permission to allow the managed cluster to access the hub cluster is automatically created within the Clusterrole and allows the agent to send events to the hub cluster. To continue adding and managing clusters, see the Cluster lifecycle introduction . 1.6.2. Release images When you build your cluster, use the version of Red Hat OpenShift Container Platform that the release image specifies. By default, OpenShift Container Platform uses the clusterImageSets resources to get the list of supported release images. Continue reading to learn more about release images: Specifying release images Maintaining a custom list of release images while connected Maintaining a custom list of release images while disconnected Synchronizing available release images 1.6.2.1. Specifying release images When you create a cluster on a provider by using multicluster engine for Kubernetes operator, specify a release image to use for your new cluster. To specify a release image, see the following topics: Locating ClusterImageSets Configuring ClusterImageSets Creating a release image to deploy a cluster on a different architecture 1.6.2.1.1. Locating ClusterImageSets The YAML files referencing the release images are maintained in the acm-hive-openshift-releases GitHub repository. The files are used to create the list of the available release images in the console. This includes the latest fast channel images from OpenShift Container Platform. The console only displays the latest release images for the three latest versions of OpenShift Container Platform. For example, you might see the following release image displayed in the console options: quay.io/openshift-release-dev/ocp-release:4.14.1-x86_64 The console displays the latest versions to help you create a cluster with the latest release images. If you need to create a cluster that is a specific version, older release image versions are also available. Note: You can only select images with the visible: 'true' label when creating clusters in the console. An example of this label in a ClusterImageSet resource is provided in the following content. Replace 4.x.1 with the current version of the product: apiVersion: hive.openshift.io/v1 kind: ClusterImageSet metadata: labels: channel: fast visible: 'true' name: img4.x.1-x86-64-appsub spec: releaseImage: quay.io/openshift-release-dev/ocp-release:4.x.1-x86_64 Additional release images are stored, but are not visible in the console. To view all of the available release images, run the following command: The repository has the clusterImageSets directory, which is the directory that you use when working with the release images. The clusterImageSets directory has the following directories: Fast: Contains files that reference the latest versions of the release images for each supported OpenShift Container Platform version. The release images in this folder are tested, verified, and supported. Releases: Contains files that reference all of the release images for each OpenShift Container Platform version (stable, fast, and candidate channels) Note: These releases have not all been tested and determined to be stable. Stable: Contains files that reference the latest two stable versions of the release images for each supported OpenShift Container Platform version.. Note: By default, the current list of release images updates one time every hour. After upgrading the product, it might take up to one hour for the list to reflect the recommended release image versions for the new version of the product. 1.6.2.1.2. Configuring ClusterImageSets You can configure your ClusterImageSets with the following options: Option 1: To create a cluster in the console, specify the image reference for the specific ClusterImageSet that you want to us. Each new entry you specify persists and is available for all future cluster provisions See the following example entry: Option 2: Manually create and apply a ClusterImageSets YAML file from the acm-hive-openshift-releases GitHub repository. Option 3: To enable automatic updates of ClusterImageSets from a forked GitHub repository, follow the README.md in the cluster-image-set-controller GitHub repository. 1.6.2.1.3. Creating a release image to deploy a cluster on a different architecture You can create a cluster on an architecture that is different from the architecture of the hub cluster by manually creating a release image that has the files for both architectures. For example, you might need to create an x86_64 cluster from a hub cluster that is running on the ppc64le , aarch64 , or s390x architecture. If you create the release image with both sets of files, the cluster creation succeeds because the new release image enables the OpenShift Container Platform release registry to provide a multi-architecture image manifest. OpenShift Container Platform supports multiple architectures by default. You can use the following clusterImageSet to provision a cluster. Replace 4.x.0 with the current supported version: apiVersion: hive.openshift.io/v1 kind: ClusterImageSet metadata: labels: channel: fast visible: 'true' name: img4.x.0-multi-appsub spec: releaseImage: quay.io/openshift-release-dev/ocp-release:4.x.0-multi To create the release image for OpenShift Container Platform images that do not support multiple architectures, complete steps similar to the following example for your architecture type: From the OpenShift Container Platform release registry , create a manifest list that includes x86_64 , s390x , aarch64 , and ppc64le release images. Pull the manifest lists for both architectures in your environment from the Quay repository by running the following example commands. Replace 4.x.1 with the current version of the product: Log in to your private repository where you maintain your images by running the following command. Replace <private-repo> with the path to your repository: Add the release image manifest to your private repository by running the following commands that apply to your environment. Replace 4.x.1 with the current version of the product. Replace <private-repo> with the path to your repository: Create a manifest for the new information by running the following command: Add references to both release images to the manifest list by running the following commands. Replace 4.x.1 with the current version of the product. Replace <private-repo> with the path to your repository: Merge the list in your manifest list with the existing manifest by running the following command. Replace <private-repo> with the path to your repository. Replace 4.x.1 with the current version: On the hub cluster, create a release image that references the manifest in your repository. Create a YAML file that contains information that is similar to the following example. Replace <private-repo> with the path to your repository. Replace 4.x.1 with the current version: apiVersion: hive.openshift.io/v1 kind: ClusterImageSet metadata: labels: channel: fast visible: "true" name: img4.x.1-appsub spec: releaseImage: <private-repo>/ocp-release:4.x.1 Run the following command on your hub cluster to apply the changes. Replace <file-name> with the name of the YAML file that you created in the step: Select the new release image when you create your OpenShift Container Platform cluster. If you deploy the managed cluster by using the Red Hat Advanced Cluster Management console, specify the architecture for the managed cluster in the Architecture field during the cluster creation process. The creation process uses the merged release images to create the cluster. 1.6.2.1.4. Additional resources See the acm-hive-openshift-releases GitHub repository for the YAML files that reference the release images. See the cluster-image-set-controller GitHub repository to learn how to enable enable automatic updates of ClusterImageSets resources from a forked GitHub repository. 1.6.2.2. Maintaining a custom list of release images when connected You might want to use the same release image for all of your clusters. To simplify, you can create your own custom list of release images that are available when creating a cluster. Complete the following steps to manage your available release images: Fork the acm-hive-openshift-releases GitHub . Add the YAML files for the images that you want available when you create a cluster. Add the images to the ./clusterImageSets/stable/ or ./clusterImageSets/fast/ directory by using the Git console or the terminal. Create a ConfigMap in the multicluster-engine namespace named cluster-image-set-git-repo . See the following example, but replace 2.x with 2.6: apiVersion: v1 kind: ConfigMap metadata: name: cluster-image-set-git-repo namespace: multicluster-engine data: gitRepoUrl: <forked acm-hive-openshift-releases repository URL> gitRepoBranch: backplane-<2.x> gitRepoPath: clusterImageSets channel: <fast or stable> You can retrieve the available YAML files from the main repository by merging changes in to your forked repository with the following procedure: Commit and merge your changes to your forked repository. To synchronize your list of fast release images after you clone the acm-hive-openshift-releases repository, update the value of channel field in the cluster-image-set-git-repo ConfigMap to fast . To synchronize and display the stable release images, update the value of channel field in the cluster-image-set-git-repo ConfigMap to stable . After updating the ConfigMap , the list of available stable release images updates with the currently available images in about one minute. You can use the following commands to list what is available and remove the defaults. Replace <clusterImageSet_NAME> with the correct name: View the list of currently available release images in the console when you are creating a cluster. For information regarding other fields available through the ConfigMap , view the cluster-image-set-controller GitHub repository README . 1.6.2.3. Maintaining a custom list of release images while disconnected In some cases, you need to maintain a custom list of release images when the hub cluster has no Internet connection. You can create your own custom list of release images that are available when creating a cluster. Complete the following steps to manage your available release images while disconnected: While you are on a connected system, navigate to the acm-hive-openshift-releases GitHub repository to access the cluster image sets that are available. Copy the clusterImageSets directory to a system that can access the disconnected multicluster engine operator cluster. Add the mapping between the managed cluster and the disconnected repository with your cluster image sets by completing the following steps that fits your managed cluster: For an OpenShift Container Platform managed cluster, see Configuring image registry repository mirroring for information about using your ImageContentSourcePolicy object to complete the mapping. For a managed cluster that is not an OpenShift Container Platform cluster, use the ManageClusterImageRegistry custom resource definition to override the location of the image sets. See Specifying registry images on managed clusters for import for information about how to override the cluster for the mapping. Add the YAML files for the images that you want available when you create a cluster by using the console or CLI to manually add the clusterImageSet YAML content. Modify the clusterImageSet YAML files for the remaining OpenShift Container Platform release images to reference the correct offline repository where you store the images. Your updates resemble the following example where spec.releaseImage uses your offline image registry of the release image, and the release image is referenced by digest: apiVersion: hive.openshift.io/v1 kind: ClusterImageSet metadata: labels: channel: fast name: img<4.x.x>-x86-64-appsub spec: releaseImage: IMAGE_REGISTRY_IPADDRESS_or__DNSNAME/REPO_PATH/ocp-release@sha256:073a4e46289be25e2a05f5264c8f1d697410db66b960c9ceeddebd1c61e58717 Ensure that the images are loaded in the offline image registry that is referenced in the YAML file. Obtain the image digest by running the following command: oc adm release info <tagged_openshift_release_image> | grep "Pull From" Replace <tagged_openshift_release_image> with the tagged image for the supported OpenShift Container Platform version. See the following example output: Pull From: quay.io/openshift-release-dev/ocp-release@sha256:69d1292f64a2b67227c5592c1a7d499c7d00376e498634ff8e1946bc9ccdddfe To learn more about the image tag and digest, see Referencing images in imagestreams . Create each of the clusterImageSets by entering the following command for each YAML file: Replace clusterImageSet_FILE with the name of the cluster image set file. For example: After running this command for each resource you want to add, the list of available release images are available. Alternately you can paste the image URL directly in the create cluster console. Adding the image URL creates new clusterImageSets if they do not exist. View the list of currently available release images in the console when you are creating a cluster. 1.6.2.4. Synchronizing available release images If you have the Red Hat Advanced Cluster Management hub cluster, which uses the MultiClusterHub operator to manage, upgrade, and install hub cluster components, you can synchronize the list of release images to ensure that you can select the latest available versions. Release images are available in the acm-hive-openshift-releases repository and are updated frequently. 1.6.2.4.1. Stability levels There are three levels of stability of the release images, as displayed in the following table: Table 1.4. Stability levels of release images Category Description candidate The most current images, which are not tested and might have some bugs. fast Images that are partially tested, but likely less stable than a stable version. stable These fully-tested images are confirmed to install and build clusters correctly. 1.6.2.4.2. Refreshing the release images list Complete the following steps to refresh and synchronize the list of images by using a Linux or Mac operating system: If the installer-managed acm-hive-openshift-releases subscription is enabled, disable the subscription by setting the value of disableUpdateClusterImageSets to true in the MultiClusterHub resource. Clone the acm-hive-openshift-releases GitHub repository. Remove the subscription by running the following command: oc delete -f subscribe/subscription-fast To synchronize and display the candidate release images, run the following command by using a Linux or Mac operating system: make subscribe-candidate After about one minute, the latest list of candidate release images is available. To synchronize and display the fast release images, run the following command: make subscribe-fast After about one minute, the latest list of fast release images is available. Connect to the stable release images and synchronize your Red Hat Advanced Cluster Management hub cluster. Run the following command using a Linux or Mac operating system: make subscribe-stable After about one minute, the list of available candidate , fast , and stable release images updates with the currently available images. View the list of currently available release images in the Red Hat Advanced Cluster Management console when you are creating a cluster. Unsubscribe from any of these channels to stop viewing the updates by running the following command: oc delete -f subscribe/subscription-fast 1.6.3. Host inventory introduction The host inventory management and on-premises cluster installation are available using the multicluster engine operator central infrastructure management feature. Central infrastructure management runs the Assisted Installer (also called infrastructure operator) as an operator on the hub cluster. You can use the console to create a host inventory, which is a pool of bare metal or virtual machines that you can use to create on-premises OpenShift Container Platform clusters. These clusters can be standalone, with dedicated machines for the control plane, or hosted control planes , where the control plane runs as pods on a hub cluster. You can install standalone clusters by using the console, API, or GitOps by using Zero Touch Provisioning (ZTP). See Installing GitOps ZTP in a disconnected environment in the Red Hat OpenShift Container Platform documentation for more information on ZTP. A machine joins the host inventory after booting with a Discovery Image. The Discovery Image is a Red Hat CoreOS live image that contains the following: An agent that performs discovery, validation, and installation tasks. The necessary configuration for reaching the service on the hub cluster, including the endpoint, token, and static network configuration, if applicable. You generally have a single Discovery Image for each infrastructure environment, which is a set of hosts sharing a common set of properties. The InfraEnv custom resource definition represents this infrastructure environment and associated Discovery Image. The image used is based on your OpenShift Container Platform version, which determines the operating system version that is selected. After the host boots and the agent contacts the service, the service creates a new Agent custom resource on the hub cluster representing that host. The Agent resources make up the host inventory. You can install hosts in the inventory as OpenShift nodes later. The agent writes the operating system to the disk, along with the necessary configuration, and reboots the host. Note: Red Hat Advanced Cluster Management 2.9 and later and central infrastructure management support the Nutanix platform by using AgentClusterInstall , which requires additional configuration by creating the Nutanix virtual machines. To learn more, see Optional: Installing on Nutanix in the Assisted Installer documentation.

Enabling the central infrastructure management service The central infrastructure management service is provided with the multicluster engine operator and deploys OpenShift Container Platform clusters. Central infrastructure management is deployed automatically when you enable the MultiClusterHub Operator on the hub cluster, but you have to enable the service manually. See the following sections: Creating a bare metal host custom resource definition Creating or modifying the Provisioning resource Enabling central infrastructure management in disconnected environments Enabling central infrastructure management in connected environments Installing a FIPS-enabled cluster by using the Infrastructure Operator for Red Hat OpenShift 1.6.3.1.1. Prerequisites See the following prerequisites before enabling the central infrastructure management service: You must have a deployed hub cluster on a supported OpenShift Container Platform version and a supported Red Hat Advanced Cluster Management for Kubernetes version. You need internet access for your hub cluster (connected), or a connection to an internal or mirror registry that has a connection to the internet (disconnected) to retrieve the required images for creating the environment. You must open the required ports for bare metal provisioning. See Ensuring required ports are open in the OpenShift Container Platform documentation. You need a bare metal host custom resource definition. You need an OpenShift Container Platform pull secret . See Using image pull secrets for more information. You need a configured default storage class. For disconnected environments only, complete the procedure for Clusters at the network far edge in the OpenShift Container Platform documentation. 1.6.3.1.2. Creating a bare metal host custom resource definition You need a bare metal host custom resource definition before enabling the central infrastructure management service. Check if you already have a bare metal host custom resource definition by running the following command: oc get crd baremetalhosts.metal3.io If you have a bare metal host custom resource definition, the output shows the date when the resource was created. If you do not have the resource, you receive an error that resembles the following: Error from server (NotFound): customresourcedefinitions.apiextensions.k8s.io "baremetalhosts.metal3.io" not found If you do not have a bare metal host custom resource definition, download the metal3.io_baremetalhosts.yaml file and apply the content by running the following command to create the resource: oc apply -f 1.6.3.1.3. Creating or modifying the Provisioning resource You need a Provisioning resource before enabling the central infrastructure management service. Check if you have the Provisioning resource by running the following command: oc get provisioning If you already have a Provisioning resource, continue by Modifying the Provisioning resource . If you do not have a Provisioning resource, you receive a No resources found error. Continue by Creating the Provisioning resource . 1.6.3.1.3.1. Modifying the Provisioning resource If you already have a Provisioning resource, you must modify the resource if your hub cluster is installed on one of the following platforms: Bare metal Red Hat OpenStack Platform VMware vSphere User-provisioned infrastructure (UPI) method and the platform is None If your hub cluster is installed on a different platform, continue at Enabling central infrastructure management in disconnected environments or Enabling central infrastructure management in connected environments . Modify the Provisioning resource to allow the Bare Metal Operator to watch all namespaces by running the following command: oc patch provisioning provisioning-configuration --type merge -p '{"spec":{"watchAllNamespaces": true }}' 1.6.3.1.3.2. Creating the Provisioning resource If you do not have a Provisioning resource, complete the following steps: Create the Provisioning resource by adding the following YAML content: apiVersion: metal3.io/v1alpha1 kind: Provisioning metadata: name: provisioning-configuration spec: provisioningNetwork: "Disabled" watchAllNamespaces: true Apply the content by running the following command: oc apply -f 1.6.3.1.4. Enabling central infrastructure management in disconnected environments To enable central infrastructure management in disconnected environments, complete the following steps: Create a ConfigMap in the same namespace as your infrastructure operator to specify the values for ca-bundle.crt and registries.conf for your mirror registry. Your file ConfigMap might resemble the following example: apiVersion: v1 kind: ConfigMap metadata: name: <mirror-config> namespace: multicluster-engine labels: app: assisted-service data: ca-bundle.crt: | <certificate-content> registries.conf: | unqualified-search-registries = ["registry.access.redhat.com", "docker.io"] [[registry]] prefix = "" location = "registry.redhat.io/multicluster-engine" mirror-by-digest-only = true [[registry.mirror]] location = "mirror.registry.com:5000/multicluster-engine" Note: You must set mirror-by-digest-only to true because release images are specified by using a digest. Registries in the list of unqualified-search-registries are automatically added to an authentication ignore list in the PUBLIC_CONTAINER_REGISTRIES environment variable. The specified registries do not require authentication when the pull secret of the managed cluster is validated. Write the key pairs representing the headers and query parameters that you want to send with every osImage request. If you don't need both parameters, write key pairs for only headers or query parameters. Important: Headers and query parameters are only encrypted if you use HTTPS. Make sure to use HTTPS to avoid security issues. Create a file named headers and add content that resembles the following example: { "Authorization": "Basic xyz" } Create a file named query_params and add content that resembles the following example: { "api_key": "myexampleapikey", } Create a secret from the parameter files that you created by running the following command. If you only created one parameter file, remove the argument for the file that you didn't create: oc create secret generic -n multicluster-engine os-images-http-auth --from-file=./query_params --from-file=./headers If you want to use HTTPS osImages with a self-signed or third-party CA certificate, add the certificate to the image-service-additional-ca ConfigMap . To create a certificate, run the following command: oc -n multicluster-engine create configmap image-service-additional-ca --from-file=tls.crt Create the AgentServiceConfig custom resource by saving the following YAML content in the agent_service_config.yaml file: apiVersion: agent-install.openshift.io/v1beta1 kind: AgentServiceConfig metadata: name: agent spec: databaseStorage: accessModes: - ReadWriteOnce resources: requests: storage: <db_volume_size> filesystemStorage: accessModes: - ReadWriteOnce resources: requests: storage: <fs_volume_size> mirrorRegistryRef: name: <mirror_config> 1 unauthenticatedRegistries: - <unauthenticated_registry> 2 imageStorage: accessModes: - ReadWriteOnce resources: requests: storage: <img_volume_size> 3 OSImageAdditionalParamsRef: name: os-images-http-auth OSImageCACertRef: name: image-service-additional-ca osImages: - openshiftVersion: "<ocp_version>" 4 version: "<ocp_release_version>" 5 url: "<iso_url>" 6 cpuArchitecture: "x86_64" + 1 Replace mirror_config with the name of the ConfigMap that contains your mirror registry configuration details. 2 Include the optional unauthenticated_registry parameter if you are using a mirror registry that does not require authentication. Entries on this list are not validated or required to have an entry in the pull secret. 3 Replace img_volume_size with the size of the volume for the imageStorage field, for example 10Gi per operating system image. The minimum value is 10Gi , but the recommended value is at least 50Gi . This value specifies how much storage is allocated for the images of the clusters. You need to allow 1 GB of image storage for each instance of Red Hat Enterprise Linux CoreOS that is running. You might need to use a higher value if there are many clusters and instances of Red Hat Enterprise Linux CoreOS. 4 Replace ocp_version with the OpenShift Container Platform version to install, for example, 4.14 . 5 Replace ocp_release_version with the specific install version, for example, 49.83.202103251640-0 . 6 Replace iso_url with the ISO url, for example, https://mirror.openshift.com/pub/openshift-v4/x86_64/dependencies/rhcos/4.13/4.13.3/rhcos-4.13.3-x86_64-live.x86_64.iso . You can find other values at the rhoc . If you are using HTTPS osImages with self-signed or third-party CA certificates, reference the certificate in the OSImageCACertRef spec. Important: If you are using the late binding feature and the spec.osImages releases in the AgentServiceConfig custom resource are version 4.13 or later, the OpenShift Container Platform release images that you use when creating your clusters must be the same. The Red Hat Enterprise Linux CoreOS images for version 4.13 and later are not compatible with earlier images. You can verify that your central infrastructure management service is healthy by checking the assisted-service and assisted-image-service deployments and ensuring that their pods are ready and running. 1.6.3.1.5. Enabling central infrastructure management in connected environments To enable central infrastructure management in connected environments, create the AgentServiceConfig custom resource by saving the following YAML content in the agent_service_config.yaml file: apiVersion: agent-install.openshift.io/v1beta1 kind: AgentServiceConfig metadata: name: agent spec: databaseStorage: accessModes: - ReadWriteOnce resources: requests: storage: <db_volume_size> 1 filesystemStorage: accessModes: - ReadWriteOnce resources: requests: storage: <fs_volume_size> 2 imageStorage: accessModes: - ReadWriteOnce resources: requests: storage: <img_volume_size> 3 1 Replace db_volume_size with the volume size for the databaseStorage field, for example 10Gi . This value specifies how much storage is allocated for storing files such as database tables and database views for the clusters. The minimum value that is required is 1Gi . You might need to use a higher value if there are many clusters. 2 Replace fs_volume_size with the size of the volume for the filesystemStorage field, for example 200M per cluster and 2-3Gi per supported OpenShift Container Platform version. The minimum value that is required is 1Gi , but the recommended value is at least 100Gi . This value specifies how much storage is allocated for storing logs, manifests, and kubeconfig files for the clusters. You might need to use a higher value if there are many clusters. 3 Replace img_volume_size with the size of the volume for the imageStorage field, for example 10Gi per operating system image. The minimum value is 10Gi , but the recommended value is at least 50Gi . This value specifies how much storage is allocated for the images of the clusters. You need to allow 1 GB of image storage for each instance of Red Hat Enterprise Linux CoreOS that is running. You might need to use a higher value if there are many clusters and instances of Red Hat Enterprise Linux CoreOS. Your central infrastructure management service is configured. You can verify that it is healthy by checking the assisted-service and assisted-image-service deployments and ensuring that their pods are ready and running. 1.6.3.1.6. Installing a FIPS-enabled cluster by using the Infrastructure Operator for Red Hat OpenShift When you install a OpenShift Container Platform cluster version 4.15 and earlier that is in FIPS mode, you must specify that the installers run Red Hat Enterprise Linux (RHEL) version 8 in the AgentServiceConfig resource. Required access: You must have access to edit the AgentServiceConfig and AgentClusterInstall resources. Complete the following steps to update the AgentServiceConfig resource: Log in to you managed cluster by using the following command: oc login Add the agent-install.openshift.io/service-image-base: el8 annotation in the AgentServiceConfig resource. Your AgentServiceConfig resource might resemble the following YAML: apiVersion: agent-install.openshift.io/v1beta1 kind: AgentServiceConfig metadata: annotations: agent-install.openshift.io/service-image-base: el8 ... 1.6.3.1.7. Additional resources For additional information about zero touch provisioning, see Clusters at the network far edge in the OpenShift Container Platform documentation. See Using image pull secrets 1.6.3.2. Enabling central infrastructure management on Amazon Web Services If you are running your hub cluster on Amazon Web Services and want to enable the central infrastructure management service, complete the following steps after Enabling the central infrastructure management service : Make sure you are logged in at the hub cluster and find the unique domain configured on the assisted-image-service by running the following command: Your domain might resemble the following example: assisted-image-service-multicluster-engine.apps.<yourdomain>.com Make sure you are logged in at the hub cluster and create a new IngressController with a unique domain using the NLB type parameter. See the following example: apiVersion: operator.openshift.io/v1 kind: IngressController metadata: name: ingress-controller-with-nlb namespace: openshift-ingress-operator spec: domain: nlb-apps.<domain>.com routeSelector: matchLabels: router-type: nlb endpointPublishingStrategy: type: LoadBalancerService loadBalancer: scope: External providerParameters: type: AWS aws: type: NLB Add <yourdomain> to the domain parameter in IngressController by replacing <domain> in nlb-apps.<domain>.com with <yourdomain> . Apply the new IngressController by running the following command: Make sure that the value of the spec.domain parameter of the new IngressController is not in conflict with an existing IngressController by completing the following steps: List all IngressControllers by running the following command: Run the following command on each of the IngressControllers , except the ingress-controller-with-nlb that you just created: If the spec.domain report is missing, add a default domain that matches all of the routes that are exposed in the cluster except nlb-apps.<domain>.com . If the spec.domain report is provided, make sure that the nlb-apps.<domain>.com route is excluded from the specified range. Run the following command to edit the assisted-image-service route to use the nlb-apps location: The default namespace is where you installed the multicluster engine operator. Add the following lines to the assisted-image-service route: metadata: labels: router-type: nlb name: assisted-image-service In the assisted-image-service route, find the URL value of spec.host . The URL might resemble the following example: Replace apps in the URL with nlb-apps to match the domain configured in the new IngressController . To verify that the central infrastructure management service is enabled on Amazon Web Services, run the following command to verify that the pods are healthy: Create a new host inventory and ensure that the download URL uses the new nlb-apps URL. 1.6.3.3. Creating a host inventory by using the console You can create a host inventory (infrastructure environment) to discover physical or virtual machines that you can install your OpenShift Container Platform clusters on. 1.6.3.3.1. Prerequisites You must enable the central infrastructure management service. See Enabling the central infrastructure management service for more information. 1.6.3.3.2. Creating a host inventory Complete the following steps to create a host inventory by using the console: From the console, navigate to Infrastructure > Host inventory and click Create infrastructure environment . Add the following information to your host inventory settings: Name: A unique name for your infrastructure environment. Creating an infrastructure environment by using the console also creates a new namespace for the InfraEnv resource with the name you chose. If you create InfraEnv resources by using the command line interface and want to monitor the resources in the console, use the same name for your namespace and the InfraEnv . Network type: Specifies if the hosts you add to your infrastructure environment use DHCP or static networking. Static networking configuration requires additional steps. Location: Specifies the geographic location of the hosts. The geographic location can be used to define which data center the hosts are located. Labels: Optional field where you can add labels to the hosts that are discovered with this infrastructure environment. The specified location is automatically added to the list of labels. Infrastructure provider credentials: Selecting an infrastructure provider credential automatically populates the pull secret and SSH public key fields with information in the credential. For more information, see Creating a credential for an on-premises environment . Pull secret: Your OpenShift Container Platform pull secret that enables you to access the OpenShift Container Platform resources. This field is automatically populated if you selected an infrastructure provider credential. SSH public key: The SSH key that enables the secure communication with the hosts. You can use it to connect to the host for troubleshooting. After installing a cluster, you can no longer connect to the host with the SSH key. The key is generally in your id_rsa.pub file. The default file path is ~/.ssh/id_rsa.pub . This field is automatically populated if you selected an infrastructure provider credential that contains the value of a SSH public key. If you want to enable proxy settings for your hosts, select the setting to enable it and enter the following information: HTTP Proxy URL: The URL of the proxy for HTTP requests. HTTPS Proxy URL: The URL of the proxy for HTTP requests. The URL must start with HTTP. HTTPS is not supported. If you do not provide a value, your HTTP proxy URL is used by default for both HTTP and HTTPS connections. No Proxy domains: A list of domains separated by commas that you do not want to use the proxy with. Start a domain name with a period ( . ) to include all of the subdomains that are in that domain. Add an asterisk ( * ) to bypass the proxy for all destinations. Optionally add your own Network Time Protocol (NTP) sources by providing a comma separated list of IP or domain names of the NTP pools or servers. If you need advanced configuration options that are not available in the console, continue to Creating a host inventory by using the command line interface . If you do not need advanced configuration options, you can continue by configuring static networking, if required, and begin adding hosts to your infrastructure environment. 1.6.3.3.3. Accessing a host inventory To access a host inventory, select Infrastructure > Host inventory in the console. Select your infrastructure environment from the list to view the details and hosts. 1.6.3.3.4.

Apply the YAML content by running the following command: Create the infrastructure environment. Create the infra-env.yaml file and add the following content. Replace values where needed: apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv metadata: name: myinfraenv namespace: <your_namespace> spec: proxy: httpProxy: <http://user:password@ipaddr:port> httpsProxy: <http://user:password@ipaddr:port> noProxy: additionalNTPSources: sshAuthorizedKey: pullSecretRef: name: <name> agentLabels: <key>: <value> nmStateConfigLabelSelector: matchLabels: <key>: <value> clusterRef: name: <cluster_name> namespace: <project_name> ignitionConfigOverride: '{"ignition": {"version": "3.1.0"}, ...}' cpuArchitecture: x86_64 ipxeScriptType: DiscoveryImageAlways kernelArguments: - operation: append value: audit=0 additionalTrustBundle: <bundle> osImageVersion: <version> Table 1.5. InfraEnv field table Field Optional or required Description proxy Optional Defines the proxy settings for agents and clusters that use the InfraEnv resource. If you do not set the proxy value, agents are not configured to use a proxy. httpProxy Optional The URL of the proxy for HTTP requests. The URL must start with http . HTTPS is not supported.. httpsProxy Optional The URL of the proxy for HTTP requests. The URL must start with http . HTTPS is not supported. noProxy Optional A list of domains and CIDRs separated by commas that you do not want to use the proxy with. additionalNTPSources Optional A list of Network Time Protocol (NTP) sources (hostname or IP) to add to all hosts. They are added to NTP sources that are configured by using other options, such as DHCP. sshAuthorizedKey Optional SSH public keys that are added to all hosts for use in debugging during the discovery phase. The discovery phase is when the host boots the Discovery Image. name Required The name of the Kubernetes secret containing your pull secret. agentLabels Optional Labels that are automatically added to the Agent resources representing the hosts that are discovered with your InfraEnv . Make sure to add your key and value. nmStateConfigLabelSelector Optional Consolidates advanced network configuration such as static IPs, bridges, and bonds for the hosts. The host network configuration is specified in one or more NMStateConfig resources with labels you choose. The nmStateConfigLabelSelector property is a Kubernetes label selector that matches your chosen labels. The network configuration for all NMStateConfig labels that match this label selector is included in the Discovery Image. When you boot, each host compares each configuration to its network interfaces and applies the appropriate configuration. To learn more about advanced network configuration, see link to section Configuring advanced networking for a host inventory . clusterRef Optional References an existing ClusterDeployment resource that describes a standalone on-premises cluster. Not set by default. If clusterRef is not set, then the hosts can be bound to one or more clusters later. You can remove the host from one cluster and add it to another. If clusterRef is set, then all hosts discovered with your InfraEnv are automatically bound to the specified cluster. If the cluster is not installed yet, then all discovered hosts are part of its installation. If the cluster is already installed, then all discovered hosts are added. ignitionConfigOverride Optional Modifies the ignition configuration of the Red Hat CoreOS live image, such as adding files. Make sure to only use ignitionConfigOverride if you need it. Must use ignition version 3.1.0, regardless of the cluster version. cpuArchitecture Optional Choose one of the following supported CPU architectures: x86_64, aarch64, ppc64le, or s390x. The default value is x86_64. ipxeScriptType Optional Causes the image service to always serve the iPXE script when set to the default value of DiscoveryImageAlways and when you are using iPXE to boot. As a result, the host boots from the network discovery image. Setting the value to BootOrderControl causes the image service to decide when to return the iPXE script, depending on the host state, which causes the host to boot from the disk when the host is provisioned and is part of a cluster. kernelArguments Optional Allows modifying the kernel arguments for when the Discovery Image boots. Possible values for operation are append , replace , or delete . additionalTrustBundle Optional A PEM-encoded X.509 certificate bundle, usually needed if the hosts are in a network with a re-encrypting man-in-the-middle (MITM) proxy, or if the hosts need to trust certificates for other purposes, such as container image registries. Hosts discovered by your InfraEnv trust the certificates in this bundle. Clusters created from the hosts discovered by your InfraEnv also trust the certificates in this bundle. osImageVersion Optional The Red Hat CoreOS image version to use for your InfraEnv . Make sure the version refers to the OS image specified in either the AgentServiceConfig.spec.osImages or in the default OS images list. Each release has a specific set of Red Hat CoreOS image versions. The OSImageVersion must match an OpenShift Container Platform version in the OS images list. You cannot specify OSImageVersion and ClusterRef at the same time. If you want to use another version of the Red Hat CoreOS image that does not exist by default, then you must manually add the version by specifying it in the AgentServiceConfig.spec.osImages . To learn more about adding versions, see Enabling the central infrastructure management service . Apply the YAML content by running the following command: To verify that your host inventory is created, check the status with the following command: See the following list of notable properties: conditions : The standard Kubernetes conditions indicating if the image was created succesfully. isoDownloadURL : The URL to download the Discovery Image. createdTime : The time at which the image was last created. If you modify the InfraEnv , make sure that the timestamp has been updated before downloading a new image. Note: If you modify the InfraEnv resource, make sure that the InfraEnv has created a new Discovery Image by looking at the createdTime property. If you already booted hosts, boot them again with the latest Discovery Image. You can continue by configuring static networking, if required, and begin adding hosts to your infrastructure environment. 1.6.3.4.3. Additional resources See Enabling the central infrastructure management service . 1.6.3.5. Configuring advanced networking for an infrastructure environment For hosts that require networking beyond DHCP on a single interface, you must configure advanced networking. The required configuration includes creating one or more instances of the NMStateConfig resource that describes the networking for one or more hosts. Each NMStateConfig resource must contain a label that matches the nmStateConfigLabelSelector on your InfraEnv resource. See Creating a host inventory by using the command line interface to learn more about the nmStateConfigLabelSelector . The Discovery Image contains the network configurations defined in all referenced NMStateConfig resources. After booting, each host compares each configuration to its network interfaces and applies the appropriate configuration. 1.6.3.5.1. Prerequisites You must enable the central infrastructure management service. You must create a host inventory. 1.6.3.5.2. Configuring advanced networking by using the command line interface To configure advanced networking for your infrastructure environment by using the command line interface, complete the following steps: Create a file named nmstateconfig.yaml and add content that is similar to the following template. Replace values where needed: apiVersion: agent-install.openshift.io/v1beta1 kind: NMStateConfig metadata: name: mynmstateconfig namespace: <your-infraenv-namespace> labels: some-key: <some-value> spec: config: interfaces: - name: eth0 type: ethernet state: up mac-address: 02:00:00:80:12:14 ipv4: enabled: true address: - ip: 192.168.111.30 prefix-length: 24 dhcp: false - name: eth1 type: ethernet state: up mac-address: 02:00:00:80:12:15 ipv4: enabled: true address: - ip: 192.168.140.30 prefix-length: 24 dhcp: false dns-resolver: config: server: - 192.168.126.1 routes: config: - destination: 0.0.0.0/0 -hop-address: 192.168.111.1 -hop-interface: eth1 table-id: 254 - destination: 0.0.0.0/0 -hop-address: 192.168.140.1 -hop-interface: eth1 table-id: 254 interfaces: - name: "eth0" macAddress: "02:00:00:80:12:14" - name: "eth1" macAddress: "02:00:00:80:12:15" Table 1.6. NMStateConfig field table Field Optional or required Description name Required Use a name that is relevant to the host or hosts you are configuring. namespace Required The namespace must match the namespace of your InfraEnv resource. some-key Required Add one or more labels that match the nmStateConfigLabelSelector on your InfraEnv resource. config Optional Describes the network settings in NMstate format. See Declarative Network API for the format specification and additional examples. The configuration can also apply to a single host, where you have one NMStateConfig resource per host, or can describe the interfaces for multiple hosts in a single NMStateConfig resource. interfaces Optional Describes the mapping between interface names found in the specified NMstate configuration and MAC addresses found on the hosts. Make sure the mapping uses physical interfaces present on a host. For example, when the NMState configuration defines a bond or VLAN, the mapping only contains an entry for parent interfaces. The mapping has the following purposes: * Allows you to use interface names in the configuration that do not match the interface names on a host. You might find this useful because the operating system chooses the interface names, which might not be predictable. * Tells a host what MAC addresses to look for after booting and applies the correct NMstate configuration. Note: The Image Service automatically creates a new image when you update any InfraEnv properties or change the NMStateConfig resources that match its label selector. If you add NMStateConfig resources after creating the InfraEnv resource, make sure that the InfraEnv creates a new Discovery Image by checking the createdTime property in your InfraEnv . If you already booted hosts, boot them again with the latest Discovery Image. Apply the YAML content by running the following command: 1.6.3.5.3. Additional resources See Creating a host inventory by using the command line interface See Declarative Network API 1.6.3.6. Adding hosts to the host inventory by using the Discovery Image After you create your host inventory (infrastructure environment), you can discover your hosts and add them to your inventory. To add hosts to your inventory, choose a method to download an ISO file and attach it to each server. For example, you can download ISO files by using a virtual media, or by writing the ISO file to a USB drive. Important: To prevent the installation from failing, keep the Discovery ISO media connected to the device during the installation process, and set each host to boot from the device one time. Prerequisites Adding hosts by using the console Adding hosts by using the command line interface 1.6.3.6.1. Prerequisites You must enable the central infrastructure management service.

See Creating a host inventory by using the command line interface for more information about the InfraEnv resource. Each booted host creates an Agent resource in the same namespace. Run the following command to view the download URL in the InfraEnv custom resource: oc get infraenv -n <infra env namespace> <infra env name> -o jsonpath='{.status.isoDownloadURL}' See the following output: Note: By default, the ISO that is provided is a minimal ISO. The minimal ISO does not contain the root file system, RootFS . The RootFS is downloaded later. To display full ISO, replace minimal.iso in the URL with full.iso . Use the URL to download the ISO file and boot your hosts with the ISO file. , you need to approve each host. See the following procedure: Run the following command to list all of your Agents : oc get agent -n <infra env namespace> You get an output that is similar to the following output: Approve any Agent from the list with a false approval status. Run the following command: oc patch agent -n <infra env namespace> <agent name> -p '{"spec":{"approved":true}}' --type merge Run the following command to confirm approval status: oc get agent -n <infra env namespace> You get an output that is similar to the following output with a true value: 1.6.3.6.4.

Automatically adding bare metal hosts to the host inventory After creating your infrastructure environment, you can discover your hosts and add them to your host inventory. You can automate booting the Discovery Image of your infrastructure environment by making the bare metal operator communicate with the Baseboard Management Controller (BMC) of each bare metal host. Create a BareMetalHost resource and associated BMC secret for each host. The automation is initiated by a label on the BareMetalHost that references your infrastructure environment. The automation performs the following actions: Boots each bare metal host with the Discovery Image represented by the infrastructure environment Reboots each host with the latest Discovery Image in case the infrastructure environment or any associated network configurations is updated Associates each Agent resource with its corresponding BareMetalHost resource upon discovery Updates Agent resource properties based on information from the BareMetalHost , such as hostname, role, and installation disk Approves the Agent for use as a cluster node 1.6.3.7.1. Prerequisites You must enable the central infrastructure management service. You must create a host inventory. 1.6.3.7.2. Adding bare metal hosts by using the console Complete the following steps to automatically add bare metal hosts to your host inventory by using the console: Select Infrastructure > Host inventory in the console. Select your infrastructure environment from the list. Click Add hosts and select With BMC Form . Add the required information and click Create . To learn more about BMC address formatting, see BMC addressing in the additional resources section. 1.6.3.7.3. Adding bare metal hosts by using the command line interface Complete the following steps to automatically add bare metal hosts to your host inventory by using the command line interface. Create a BMC secret by applying the following YAML content and replacing values where needed: apiVersion: v1 kind: Secret metadata: name: <bmc-secret-name> namespace: <your_infraenv_namespace> 1 type: Opaque data: username: <username> password: <password> 1 The namespace must be the same as the namespace of your InfraEnv . Create a bare metal host by applying the following YAML content and replacing values where needed: apiVersion: metal3.io/v1alpha1 kind: BareMetalHost metadata: name: <bmh-name> namespace: <your-infraenv-namespace> 1 annotations: inspect.metal3.io: disabled bmac.agent-install.openshift.io/hostname: <hostname> 2 bmac.agent-install.openshift.io/role: <role> 3 labels: infraenvs.agent-install.openshift.io: <your-infraenv> 4 spec: online: true automatedCleaningMode: disabled 5 bootMACAddress: <your-mac-address> 6 bmc: address: <machine-address> 7 credentialsName: <bmc-secret-name> 8 rootDeviceHints: deviceName: /dev/sda 9 1 The namespace must be the same as the namespace of your InfraEnv . 2 Optional: Replace with the name of your host. 3 Optional: Possible values are master or worker . 4 The name must match the name of your InfrEnv and exist in the same namespace. 5 If you do not set a value, the metadata value is automatically used. 6 Make sure the MAC address matches the MAC address of one of your host interfaces. 7 Use the address of the BMC. To learn more, see Port access for the out-of-band management IP address and BMC addressing in the additional resources section. 8 Make sure that the credentialsName value matches the name of the BMC secret you created. 9 Optional: Select the installation disk. See The BareMetalHost spec for the available root device hints. After the host is booted with the Discovery Image and the corresponding Agent resource is created, the installation disk is set according to this hint. After turning on the host, the image starts downloading. This might take a few minutes. When the host is discovered, an Agent custom resource is created automatically. 1.6.3.7.4. Disabling converged flow Converged flow is enabled by default. If your hosts do not appear, you might need to temporarily disable converged flow. To disable converged flow, complete the following steps: Create the following config map on your hub cluster: apiVersion: v1 kind: ConfigMap metadata: name: my-assisted-service-config namespace: multicluster-engine data: ALLOW_CONVERGED_FLOW: "false" Note: When you set ALLOW_CONVERGED_FLOW to "false" , you also disable any features enabled by the Ironic Python Agent. Apply the config map by running the following command: oc annotate --overwrite AgentServiceConfig agent unsupported.agent-install.openshift.io/assisted-service-configmap=my-assisted-service-config 1.6.3.7.5. Removing managed cluster nodes by using the command line interface To remove managed cluster nodes from a managed cluster, you need a hub cluster that is running on a supported OpenShift Container Platform version. Any static networking configuration required for the node to boot must be available. Make sure to not delete NMStateConfig resources when you delete the agent and bare metal host. 1.6.3.7.5.1. Removing managed cluster nodes with a bare metal host If you have a bare metal host on your hub cluster and want remove managed cluster nodes from a managed cluster, complete the following steps: Add the following annotation to the BareMetalHost resource of the node that you want to delete: Delete the BareMetalHost resource by running the following command. Replace <bmh-name> with the name of your BareMetalHost : 1.6.3.7.5.2. Removing managed cluster nodes without a bare metal host If you do not have a bare metal host on your hub cluster and you want to remove managed cluster nodes from a managed cluster, you can unbind the agent by removing the clusterDeploymentName field from the Agent specification, or delete the Agent custom resource that corresponds with the node that you are removing. If you want to delete an Agent resource from the hub cluster, but do not want the node removed from the managed cluster, you can set the annotation agent.agent-install.openshift.io/skip-spoke-cleanup to true on the Agent resource before you remove it. See the Deleting nodes instructions in the OpenShift Container Platform documentation. 1.6.3.7.6. Binding and unbinding hosts You can bind hosts to an Red Hat OpenShift Container Platform cluster by setting the spec.clusterDeploymentName field in the Agent custom resource, or by setting the {}bmac.agent-install.openshift.io/cluster-reference bare metal host annotation. The {}bmac.agent-install.openshift.io/cluster-reference bare metal host annotation controls the connection to your OpenShift Container Platform cluster, and binds or unbinds hosts to a specific cluster. You can use the {}bmac.agent-install.openshift.io/cluster-reference annotation in one of the following three ways: If you do not set the annotation in the bare metal host, no changes apply to the host. If you set the annotation with an empty string value, the host unbinds. If you set the annotation and use a string value that follows the <cluster-namespace>/<cluster-name> format, the host binds to the cluster that your ClusterDeployment custom resource represents. Note: If the InfraEnv that the host belongs to already contains a cluster-reference annotation, the {}bmac.agent-install.openshift.io/cluster-reference annotation is ignored. 1.6.3.7.7.

Managing your host inventory You can manage your host inventory and edit existing hosts by using the console, or by using the command line interface and editing the Agent resource. 1.6.3.8.1. Managing your host inventory by using the console Each host that you successfully boot with the Discovery ISO appears as a row in your host inventory. You can use the console to edit and manage your hosts. If you booted the host manually and are not using the bare metal operator automation, you must approve the host in the console before you can use it. Hosts that are ready to be installed as OpenShift nodes have the Available status. 1.6.3.8.2. Managing your host inventory by using the command line interface An Agent resource represents each host. You can set the following properties in an Agent resource: clusterDeploymentName Set this property to the namespace and name of the ClusterDeployment you want to use if you want to install the host as a node in a cluster. Optional: role Sets the role for the host in the cluster. Possible values are master , worker , and auto-assign . The default value is auto-assign . hostname Sets the host name for the host. Optional if the host is automatically assigned a valid host name, for example by using DHCP. approved Indicates if the host can be installed as an OpenShift node. This property is a boolean with a default value of False . If you booted the host manually and are not using the bare metal operator automation, you must set this property to True before installing the host. installation_disk_id The ID of the installation disk you chose that is visible in the inventory of the host. installerArgs A JSON-formatted string containing overrides for the coreos-installer arguments of the host. You can use this property to modify kernel arguments. See the following example syntax: ignitionConfigOverrides A JSON-formatted string containing overrides for the ignition configuration of the host. You can use this property to add files to the host by using ignition. See the following example syntax: nodeLabels A list of labels that are applied to the node after the host is installed. The status of an Agent resource has the following properties: role Sets the role for the host in the cluster. If you previously set a role in the Agent resource, the value appears in the status . inventory Contains host properties that the agent running on the host discovers. progress The host installation progress. ntpSources The configured Network Time Protocol (NTP) sources of the host. conditions Contains the following standard Kubernetes conditions with a True or False value: SpecSynced: True if all specified properties are successfully applied. False if some error was encountered. Connected: True if the agent connection to the installation service is not obstructed. False if the agent has not contacted the installation service in some time. RequirementsMet: True if the host is ready to begin the installation. Validated: True if all host validations pass. Installed: True if the host is installed as an OpenShift node. Bound: True if the host is bound to a cluster. Cleanup: False if the request to delete the Agent resouce fails. debugInfo Contains URLs for downloading installation logs and events. validationsInfo Contains information about validations that the agent runs after the host is discovered to ensure that the installation is successful. Troubleshoot if the value is False . installation_disk_id The ID of the installation disk you chose that is visible in the inventory of the host. 1.6.3.8.3. Additional resources See Accessing a host inventory See coreos-installer install 1.6.4. Cluster creation Learn how to create Red Hat OpenShift Container Platform clusters across cloud providers with multicluster engine operator. multicluster engine operator uses the Hive operator that is provided with OpenShift Container Platform to provision clusters for all providers except the on-premises clusters and hosted control planes. When provisioning the on-premises clusters, multicluster engine operator uses the central infrastructure management and Assisted Installer function that are provided with OpenShift Container Platform. The hosted clusters for hosted control planes are provisioned by using the HyperShift operator.

Creating a cluster with the CLI The multicluster engine for Kubernetes operator uses internal Hive components to create Red Hat OpenShift Container Platform clusters. See the following information to learn how to create clusters. Prerequisites Create a cluster with ClusterDeployment Create a cluster with cluster pool 1.6.4.1.1. Prerequisites Before creating a cluster, you must clone the clusterImageSets repository and apply it to your hub cluster. See the following steps: Run the following command to clone, but replace 2.x with 2.6: Run the following command to apply it to your hub cluster: Select the Red Hat OpenShift Container Platform release images when you create a cluster. Note: If you use the Nutanix platform, be sure to use x86_64 architecture for the releaseImage in the ClusterImageSet resource and set the visible label value to 'true' . See the following example: apiVersion: hive.openshift.io/v1 kind: ClusterImageSet metadata: labels: channel: stable visible: 'true' name: img4.x.47-x86-64-appsub spec: releaseImage: quay.io/openshift-release-dev/ocp-release:4.x.47-x86_64 1.6.4.1.2. Create a cluster with ClusterDeployment A ClusterDeployment is a Hive custom resource that is used to control the lifecycle of a cluster. Follow the Using Hive documentation to create the ClusterDeployment custom resource and create an individual cluster. 1.6.4.1.3. Create a cluster with ClusterPool A ClusterPool is also a Hive custom resource that is used to create multiple clusters. Follow the Cluster Pools documentation to create a cluster with the Hive ClusterPool API. 1.6.4.2. Configuring additional manifests during cluster creation You can configure additional Kubernetes resource manifests during the installation process of creating your cluster. This can help if you need to configure additional manifests for scenarios such as configuring networking or setting up a load balancer. 1.6.4.2.1. Prerequisite Add a reference to the ClusterDeployment resource that specifies a config map resource that contains the additional resource manifests. Note: The ClusterDeployment resource and the config map must be in the same namespace. 1.6.4.2.2. Configuring additional manifests during cluster creation by using examples If you want to configure additional manifests by using a config map with resource manifests, complete the following steps: Create a YAML file and add the following example content: kind: ConfigMap apiVersion: v1 metadata: name: <my-baremetal-cluster-install-manifests> namespace: <mynamespace> data: 99_metal3-config.yaml: | kind: ConfigMap apiVersion: v1 metadata: name: metal3-config namespace: openshift-machine-api data: http_port: "6180" provisioning_interface: "enp1s0" provisioning_ip: "172.00.0.3/24" dhcp_range: "172.00.0.10,172.00.0.100" deploy_kernel_url: "http://172.00.0.3:6180/images/ironic-python-agent.kernel" deploy_ramdisk_url: "http://172.00.0.3:6180/images/ironic-python-agent.initramfs" ironic_endpoint: "http://172.00.0.3:6385/v1/" ironic_inspector_endpoint: "http://172.00.0.3:5150/v1/" cache_url: "http://192.168.111.1/images" rhcos_image_url: "https://releases-art-rhcos.svc.ci.openshift.org/art/storage/releases/rhcos-4.3/43.81.201911192044.0/x86_64/rhcos-43.81.201911192044.0-openstack.x86_64.qcow2.gz" Note: The example ConfigMap contains a manifest with another ConfigMap resource. The resource manifest ConfigMap can contain multiple keys with resource configurations added in the following pattern, data.<resource_name>\.yaml . Apply the file by running the following command: oc apply -f <filename>.yaml If you want to configure additional manifests by using a ClusterDeployment by referencing a resource manifest ConfigMap , complete the following steps: Create a YAML file and add the following example content. The resource manifest ConfigMap is referenced in spec.provisioning.manifestsConfigMapRef : apiVersion: hive.openshift.io/v1 kind: ClusterDeployment metadata: name: <my-baremetal-cluster> namespace: <mynamespace> annotations: hive.openshift.io/try-install-once: "true" spec: baseDomain: test.example.com clusterName: <my-baremetal-cluster> controlPlaneConfig: servingCertificates: {} platform: baremetal: libvirtSSHPrivateKeySecretRef: name: provisioning-host-ssh-private-key provisioning: installConfigSecretRef: name: <my-baremetal-cluster-install-config> sshPrivateKeySecretRef: name: <my-baremetal-hosts-ssh-private-key> manifestsConfigMapRef: name: <my-baremetal-cluster-install-manifests> imageSetRef: name: <my-clusterimageset> sshKnownHosts: - "10.1.8.90 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXvVVVKUYVkuyvkuygkuyTCYTytfkufTYAAAAIbmlzdHAyNTYAAABBBKWjJRzeUVuZs4yxSy4eu45xiANFIIbwE3e1aPzGD58x/NX7Yf+S8eFKq4RrsfSaK2hVJyJjvVIhUsU9z2sBJP8=" pullSecretRef: name: <my-baremetal-cluster-pull-secret> Apply the file by running the following command: oc apply -f <filename>.yaml 1.6.4.3. Creating a cluster on Amazon Web Services You can use the multicluster engine operator console to create a Red Hat OpenShift Container Platform cluster on Amazon Web Services (AWS). When you create a cluster, the creation process uses the OpenShift Container Platform installer with the Hive resource. If you have questions about cluster creation after completing this procedure, see Installing on AWS in the OpenShift Container Platform documentation for more information about the process. Prerequisites Creating your AWS cluster Creating your cluster with the console 1.6.4.3.1. Prerequisites See the following prerequisites before creating a cluster on AWS: You must have a deployed hub cluster. You need an AWS credential. See Creating a credential for Amazon Web Services for more information. You need a configured domain in AWS. See Configuring an AWS account for instructions on how to configure a domain. You must have Amazon Web Services (AWS) login credentials, which include user name, password, access key ID, and secret access key. See Understanding and Getting Your Security Credentials . You must have an OpenShift Container Platform image pull secret. See Using image pull secrets . Note: If you change your cloud provider access key on the cloud provider, you also need to manually update the corresponding credential for the cloud provider on the console. This is required when your credentials expire on the cloud provider where the managed cluster is hosted and you try to delete the managed cluster. 1.6.4.3.2. Creating your AWS cluster See the following important information about creating an AWS cluster: When you review your information and optionally customize it before creating the cluster, you can select YAML: On to view the install-config.yaml file content in the panel. You can edit the YAML file with your custom settings, if you have any updates. When you create a cluster, the controller creates a namespace for the cluster and the resources. Ensure that you include only resources for that cluster instance in that namespace. Destroying the cluster deletes the namespace and all of the resources in it. If you want to add your cluster to an existing cluster set, you must have the correct permissions on the cluster set to add it. If you do not have cluster-admin privileges when you are creating the cluster, you must select a cluster set on which you have clusterset-admin permissions. If you do not have the correct permissions on the specified cluster set, the cluster creation fails. Contact your cluster administrator to provide you with clusterset-admin permissions to a cluster set if you do not have any cluster set options to select. Every managed cluster must be associated with a managed cluster set. If you do not assign the managed cluster to a ManagedClusterSet , it is automatically added to the default managed cluster set. If there is already a base DNS domain that is associated with the selected credential that you configured with your AWS account, that value is populated in the field. You can change the value by overwriting it. This name is used in the hostname of the cluster. The release image identifies the version of the OpenShift Container Platform image that is used to create the cluster. Select the image from the list of images that are available. If the image that you want to use is not available, you can enter the URL to the image that you want to use. The node pools include the control plane pool and the worker pools. The control plane nodes share the management of the cluster activity. The information includes the following fields: Region: Specify the region where you want the node pool. CPU architecture: If the architecture type of the managed cluster is not the same as the architecture of your hub cluster, enter a value for the instruction set architecture of the machines in the pool. Valid values are amd64 , ppc64le , s390x , and arm64 . Zones: Specify where you want to run your control plane pools. You can select multiple zones within the region for a more distributed group of control plane nodes. A closer zone might provide faster performance, but a more distant zone might be more distributed. Instance type: Specify the instance type for your control plane node. You can change the type and size of your instance after it is created. Root storage: Specify the amount of root storage to allocate for the cluster. You can create zero or more worker nodes in a worker pool to run the container workloads for the cluster. This can be in a single worker pool, or distributed across multiple worker pools. If zero worker nodes are specified, the control plane nodes also function as worker nodes. The optional information includes the following fields: Zones: Specify where you want to run your worker pools. You can select multiple zones within the region for a more distributed group of nodes. A closer zone might provide faster performance, but a more distant zone might be more distributed. Instance type: Specify the instance type of your worker pools. You can change the type and size of your instance after it is created. Node count: Specify the node count of your worker pool. This setting is required when you define a worker pool. Root storage: Specify the amount of root storage allocated for your worker pool. This setting is required when you define a worker pool. Networking details are required for your cluster, and multiple networks are required for using IPv6. You can add an additional network by clicking Add network . Proxy information that is provided in the credential is automatically added to the proxy fields. You can use the information as it is, overwrite it, or add the information if you want to enable a proxy. The following list contains the required information for creating a proxy: HTTP proxy: Specify the URL that should be used as a proxy for HTTP traffic. HTTPS proxy: Specify the secure proxy URL that should be used for HTTPS traffic. If no value is provided, the same value as the HTTP Proxy URL is used for both HTTP and HTTPS . No proxy sites: A comma-separated list of sites that should bypass the proxy. Begin a domain name with a period . to include all of the subdomains that are in that domain. Add an asterisk * to bypass the proxy for all destinations. Additional trust bundle: One or more additional CA certificates that are required for proxying HTTPS connections. 1.6.4.3.3. Creating your cluster with the console To create a new cluster, see the following procedure. If you have an existing cluster that you want to import instead, see Cluster import . Note: You do not have to run the oc command that is provided with the cluster details to import the cluster. When you create the cluster, it is automatically configured under the management of multicluster engine operator. Navigate to Infrastructure > Clusters . On the Clusters page. Click Cluster > Create cluster and complete the steps in the console. Optional: Select YAML: On to view content updates as you enter the information in the console. If you need to create a credential, see Creating a credential for Amazon Web Services for more information. The name of the cluster is used in the hostname of the cluster. If you are using Red Hat Advanced Cluster Management for Kubernetes and want to configure your managed cluster klusterlet to run on specific nodes, see Optional: Configuring the klusterlet to run on specific nodes for the required steps. 1.6.4.3.4. Additional resources The AWS private configuration information is used when you are creating an AWS GovCloud cluster. See Creating a cluster on Amazon Web Services GovCloud for information about creating a cluster in that environment. See Configuring an AWS account for more information. See Release images for more information about release images. Find more information about supported instant types by visiting your cloud provider sites, such as AWS General purpose instances . 1.6.4.4. Creating a cluster on Amazon Web Services GovCloud You can use the console to create a Red Hat OpenShift Container Platform cluster on Amazon Web Services (AWS) or on AWS GovCloud. This procedure explains how to create a cluster on AWS GovCloud. See Creating a cluster on Amazon Web Services for the instructions for creating a cluster on AWS. AWS GovCloud provides cloud services that meet additional requirements that are necessary to store government documents on the cloud. When you create a cluster on AWS GovCloud, you must complete additional steps to prepare your environment. When you create a cluster, the creation process uses the OpenShift Container Platform installer with the Hive resource. If you have questions about cluster creation after completing this procedure, see Installing a cluster on AWS into a government region in the OpenShift Container Platform documentation for more information about the process. The following sections provide the steps for creating a cluster on AWS GovCloud: Prerequisites Configure Hive to deploy on AWS GovCloud Creating your cluster with the console 1.6.4.4.1. Prerequisites You must have the following prerequisites before creating an AWS GovCloud cluster: You must have AWS login credentials, which include user name, password, access key ID, and secret access key. See Understanding and Getting Your Security Credentials . You need an AWS credential. See Creating a credential for Amazon Web Services for more information. You need a configured domain in AWS. See Configuring an AWS account for instructions on how to configure a domain. You must have an OpenShift Container Platform image pull secret. See Using image pull secrets . You must have an Amazon Virtual Private Cloud (VPC) with an existing Red Hat OpenShift Container Platform cluster for the hub cluster. This VPC must be different from the VPCs that are used for the managed cluster resources or the managed cluster service endpoints. You need a VPC where the managed cluster resources are deployed. This cannot be the same as the VPCs that are used for the hub cluster or the managed cluster service endpoints. You need one or more VPCs that provide the managed cluster service endpoints. This cannot be the same as the VPCs that are used for the hub cluster or the managed cluster resources. Ensure that the IP addresses of the VPCs that are specified by Classless Inter-Domain Routing (CIDR) do not overlap. You need a HiveConfig custom resource that references a credential within the Hive namespace. This custom resource must have access to create resources on the VPC that you created for the managed cluster service endpoints. Note: If you change your cloud provider access key on the cloud provider, you also need to manually update the corresponding credential for the cloud provider on the multicluster engine operator console. This is required when your credentials expire on the cloud provider where the managed cluster is hosted and you try to delete the managed cluster. 1.6.4.4.2. Configure Hive to deploy on AWS GovCloud While creating a cluster on AWS GovCloud is almost identical to creating a cluster on standard AWS, you have to complete some additional steps to prepare an AWS PrivateLink for the cluster on AWS GovCloud. 1.6.4.4.2.1. Create the VPCs for resources and endpoints As listed in the prerequisites, two VPCs are required in addition to the VPC that contains the hub cluster. See Create a VPC in the Amazon Web Services documentation for specific steps for creating a VPC. Create a VPC for the managed cluster with private subnets. Create one or more VPCs for the managed cluster service endpoints with private subnets. Each VPC in a region has a limit of 255 VPC endpoints, so you need multiple VPCs to support more than 255 clusters in that region. For each VPC, create subnets in all of the supported availability zones of the region. Each subnet must have at least 255 usable IP addresses because of the controller requirements. The following example shows how you might structure subnets for VPCs that have 6 availability zones in the us-gov-east-1 region: Ensure that all of the hub environments (hub cluster VPCs) have network connectivity to the VPCs that you created for VPC endpoints that use peering, transit gateways, and that all DNS settings are enabled. Collect a list of VPCs that are needed to resolve the DNS setup for the AWS PrivateLink, which is required for the AWS GovCloud connectivity. This includes at least the VPC of the multicluster engine operator instance that you are configuring, and can include the list of all of the VPCs where various Hive controllers exist. 1.6.4.4.2.2. Configure the security groups for the VPC endpoints Each VPC endpoint in AWS has a security group attached to control access to the endpoint. When Hive creates a VPC endpoint, it does not specify a security group. The default security group of the VPC is attached to the VPC endpoint. The default security group of the VPC must have rules to allow traffic where VPC endpoints are created from the Hive installer pods. See Control access to VPC endpoints using endpoint policies in the AWS documentation for details. For example, if Hive is running in hive-vpc(10.1.0.0/16) , there must be a rule in the default security group of the VPC where the VPC endpoint is created that allows ingress from 10.1.0.0/16 . 1.6.4.4.2.3. Set permissions for AWS PrivateLink You need multiple credentials to configure the AWS PrivateLink. The required permissions for these credentials depend on the type of credential. The credentials for ClusterDeployment require the following permissions: The credentials for HiveConfig for endpoint VPCs account .spec.awsPrivateLink.credentialsSecretRef require the following permissions: The credentials specified in the HiveConfig custom resource for associating VPCs to the private hosted zone ( .spec.awsPrivateLink.associatedVPCs[USDidx].credentialsSecretRef ). The account where the VPC is located requires the following permissions: Ensure that there is a credential secret within the Hive namespace on the hub cluster. The HiveConfig custom resource needs to reference a credential within the Hive namespace that has permissions to create resources in a specific provided VPC. If the credential that you are using to provision an AWS cluster in AWS GovCloud is already in the Hive namespace, then you do not need to create another one. If the credential that you are using to provision an AWS cluster in AWS GovCloud is not already in the Hive namespace, you can either replace your current credential or create an additional credential in the Hive namespace. The HiveConfig custom resource needs to include the following content: An AWS GovCloud credential that has the required permissions to provision resources for the given VPC. The addresses of the VPCs for the OpenShift Container Platform cluster installation, as well as the service endpoints for the managed cluster. Best practice: Use different VPCs for the OpenShift Container Platform cluster installation and the service endpoints.

When you review your information and optionally customize it before creating the cluster, you can click the YAML switch On to view the install-config.yaml file content in the panel. You can edit the YAML file with your custom settings, if you have any updates. When creating a cluster that uses an internal certificate authority (CA), you need to customize the YAML file for your cluster by completing the following steps: With the YAML switch on at the review step, insert a Secret object at the top of the list with the CA certificate bundle. Note: If the Red Hat OpenStack Platform environment provides services using certificates signed by multiple authorities, the bundle must include the certificates to validate all of the required endpoints. The addition for a cluster named ocp3 resembles the following example: apiVersion: v1 kind: Secret type: Opaque metadata: name: ocp3-openstack-trust namespace: ocp3 stringData: ca.crt: | -----BEGIN CERTIFICATE----- <Base64 certificate contents here> -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- <Base64 certificate contents here> -----END CERTIFICATE---- Modify the Hive ClusterDeployment object to specify the value of certificatesSecretRef in spec.platform.openstack , similar to the following example: platform: openstack: certificatesSecretRef: name: ocp3-openstack-trust credentialsSecretRef: name: ocp3-openstack-creds cloud: openstack The example assumes that the cloud name in the clouds.yaml file is openstack . If you are using Red Hat Advanced Cluster Management for Kubernetes and want to configure your managed cluster klusterlet to run on specific nodes, see Optional: Configuring the klusterlet to run on specific nodes for the required steps. Note: You do not have to run the oc command that is provided with the cluster details to import the cluster. When you create the cluster, it is automatically configured under the management of multicluster engine operator. Continue with Accessing your cluster for instructions for accessing your cluster. 1.6.4.9. Creating a cluster in an on-premises environment You can use the console to create on-premises Red Hat OpenShift Container Platform clusters. The clusters can be single-node OpenShift clusters, multi-node clusters, and compact three-node clusters on VMware vSphere, Red Hat OpenStack, Nutanix, or in a bare metal environment. There is no platform integration with the platform where you install the cluster, as the platform value is set to platform=none . A single-node OpenShift cluster contains only a single node, which hosts the control plane services and the user workloads. This configuration can be helpful when you want to minimize the resource footprint of the cluster. You can also provision multiple single-node OpenShift clusters on edge resources by using the zero touch provisioning feature, which is a feature that is available with Red Hat OpenShift Container Platform. For more information about zero touch provisioning, see Clusters at the network far edge in the OpenShift Container Platform documentation. Prerequisites Creating your cluster with the console Creating your cluster with the command line 1.6.4.9.1. Prerequisites See the following prerequisites before creating a cluster in an on-premises environment: You must have a deployed hub cluster on a supported OpenShift Container Platform version. You need a configured infrastructure environment with a host inventory of configured hosts. You must have internet access for your hub cluster (connected), or a connection to an internal or mirror registry that has a connection to the internet (disconnected) to retrieve the required images for creating the cluster. You need a configured on-premises credential. You need an OpenShift Container Platform image pull secret. See Using image pull secrets . You need the following DNS records: The following API base domain must point to the static API VIP: The following application base domain must point to the static IP address for Ingress VIP: 1.6.4.9.2. Creating your cluster with the console To create a cluster from the console, complete the following steps: Navigate to Infrastructure > Clusters . On the Clusters page, click Create cluster and complete the steps in the console. Select Host inventory as the type of cluster. The following options are available for your assisted installation: Use existing discovered hosts : Select your hosts from a list of hosts that are in an existing host inventory. Discover new hosts : Discover hosts that are not already in an existing infrastructure environment. Discover your own hosts, rather than using one that is already in an infrastructure environment. If you need to create a credential, see Creating a credential for an on-premises environment for more information. The name for your cluster is used in the hostname of the cluster. Important: When you create a cluster, the controller creates a namespace for the cluster and its resources. Ensure that you include only resources for that cluster instance in that namespace. Destroying the cluster deletes the namespace and all of the resources in it. Note: Select YAML: On to view content updates as you enter the information in the console. If you want to add your cluster to an existing cluster set, you must have the correct permissions on the cluster set to add it. If you do not have cluster-admin privileges when you are creating the cluster, you must select a cluster set on which you have clusterset-admin permissions. If you do not have the correct permissions on the specified cluster set, the cluster creation fails. Contact your cluster administrator to provide you with clusterset-admin permissions to a cluster set if you do not have any cluster set options to select. Every managed cluster must be associated with a managed cluster set. If you do not assign the managed cluster to a ManagedClusterSet , it is automatically added to the default managed cluster set. If there is already a base DNS domain that is associated with the selected credential that you configured for your provider account, that value is populated in that field. You can change the value by overwriting it, but this setting cannot be changed after the cluster is created. The base domain of your provider is used to create routes to your Red Hat OpenShift Container Platform cluster components. It is configured in the DNS of your cluster provider as a Start of Authority (SOA) record. The OpenShift version identifies the version of the OpenShift Container Platform image that is used to create the cluster. If the version that you want to use is available, you can select the image from the list of images. If the image that you want to use is not a standard image, you can enter the URL to the image that you want to use. See Release images to learn more. When you select a supported OpenShift Container Platform version, an option to select Install single-node OpenShift is displayed. A single-node OpenShift cluster contains a single node which hosts the control plane services and the user workloads. See Scaling hosts to an infrastructure environment to learn more about adding nodes to a single-node OpenShift cluster after it is created. If you want your cluster to be a single-node OpenShift cluster, select the single-node OpenShift option. You can add additional workers to single-node OpenShift clusters by completing the following steps: From the console, navigate to Infrastructure > Clusters and select the name of the cluster that you created or want to access. Select Actions > Add hosts to add additional workers. Note: The single-node OpenShift control plane requires 8 CPU cores, while a control plane node for a multinode control plane cluster only requires 4 CPU cores. After you review and save the cluster, your cluster is saved as a draft cluster. You can close the creation process and finish the process later by selecting the cluster name on the Clusters page. If you are using existing hosts, select whether you want to select the hosts yourself, or if you want them to be selected automatically. The number of hosts is based on the number of nodes that you selected. For example, a single-node OpenShift cluster only requires one host, while a standard three-node cluster requires three hosts. The locations of the available hosts that meet the requirements for this cluster are displayed in the list of Host locations . For distribution of the hosts and a more high-availability configuration, select multiple locations. If you are discovering new hosts with no existing infrastructure environment, complete the steps in Adding hosts to the host inventory by using the Discovery Image . After the hosts are bound, and the validations pass, complete the networking information for your cluster by adding the following IP addresses: API VIP: Specifies the IP address to use for internal API communication. Note: This value must match the name that you used to create the DNS records listed in the prerequisites section. If not provided, the DNS must be pre-configured so that api. resolves correctly. Ingress VIP: Specifies the IP address to use for ingress traffic. Note: This value must match the name that you used to create the DNS records listed in the prerequisites section. If not provided, the DNS must be pre-configured so that test.apps. resolves correctly. If you are using Red Hat Advanced Cluster Management for Kubernetes and want to configure your managed cluster klusterlet to run on specific nodes, see Optional: Configuring the klusterlet to run on specific nodes for the required steps. You can view the status of the installation on the Clusters navigation page. Continue with Accessing your cluster for instructions for accessing your cluster. 1.6.4.9.3. Creating your cluster with the command line You can also create a cluster without the console by using the assisted installer feature within the central infrastructure management component. After you complete this procedure, you can boot the host from the discovery image that is generated. The order of the procedures is generally not important, but is noted when there is a required order. 1.6.4.9.3.1. Create the namespace You need a namespace for your resources. It is more convenient to keep all of the resources in a shared namespace. This example uses sample-namespace for the name of the namespace, but you can use any name except assisted-installer . Create a namespace by creating and applying the following file: apiVersion: v1 kind: Namespace metadata: name: sample-namespace 1.6.4.9.3.2. Add the pull secret to the namespace Add your pull secret to your namespace by creating and applying the following custom resource: apiVersion: v1 kind: Secret type: kubernetes.io/dockerconfigjson metadata: name: <pull-secret> namespace: sample-namespace stringData: .dockerconfigjson: 'your-pull-secret-json' 1 1 Add the content of the pull secret. For example, this can include a cloud.openshift.com , quay.io , or registry.redhat.io authentication. 1.6.4.9.3.3. Generate a ClusterImageSet Generate a CustomImageSet to specify the version of OpenShift Container Platform for your cluster by creating and applying the following custom resource: apiVersion: hive.openshift.io/v1 kind: ClusterImageSet metadata: name: openshift-v4.14.0 spec: releaseImage: quay.io/openshift-release-dev/ocp-release:4.14.0-rc.0-x86_64 Note: You need to create a multi-architecture ClusterImageSet if you install a managed cluster that has a different architecture than the hub cluster. To learn more, see Creating a release image to deploy a cluster on a different architecture . 1.6.4.9.3.4. Create the ClusterDeployment custom resource The ClusterDeployment custom resource definition is an API that controls the lifecycle of the cluster. It references the AgentClusterInstall custom resource in the spec.ClusterInstallRef setting which defines the cluster parameters. Create and apply a ClusterDeployment custom resource based on the following example: apiVersion: hive.openshift.io/v1 kind: ClusterDeployment metadata: name: single-node namespace: demo-worker4 spec: baseDomain: hive.example.com clusterInstallRef: group: extensions.hive.openshift.io kind: AgentClusterInstall name: test-agent-cluster-install 1 version: v1beta1 clusterName: test-cluster controlPlaneConfig: servingCertificates: {} platform: agentBareMetal: agentSelector: matchLabels: location: internal pullSecretRef: name: <pull-secret> 2 1 Use the name of your AgentClusterInstall resource. 2 Use the pull secret that you downloaded in Add the pull secret to the namespace . 1.6.4.9.3.5. Create the AgentClusterInstall custom resource In the AgentClusterInstall custom resource, you can specify many of the requirements for the clusters. For example, you can specify the cluster network settings, platform, number of control planes, and worker nodes. Create and add the a custom resource that resembles the following example: apiVersion: extensions.hive.openshift.io/v1beta1 kind: AgentClusterInstall metadata: name: test-agent-cluster-install namespace: demo-worker4 spec: platformType: BareMetal 1 clusterDeploymentRef: name: single-node 2 imageSetRef: name: openshift-v4.14.0 3 networking: clusterNetwork: - cidr: 10.128.0.0/14 hostPrefix: 23 machineNetwork: - cidr: 192.168.111.0/24 serviceNetwork: - 172.30.0.0/16 provisionRequirements: controlPlaneAgents: 1 sshPublicKey: ssh-rsa <your-public-key-here> 4 1 Specify the platform type of the environment where the cluster is created. Valid values are: BareMetal , None , VSphere , Nutanix , or External . 2 Use the same name that you used for your ClusterDeployment resource. 3 Use the ClusterImageSet that you generated in Generate a ClusterImageSet . 4 You can specify your SSH public key, which enables you to access the host after it is installed. 1.6.4.9.3.6. Optional: Create the NMStateConfig custom resource The NMStateConfig custom resource is only required if you have a host-level network configuration, such as static IP addresses. If you include this custom resource, you must complete this step before creating an InfraEnv custom resource. The NMStateConfig is referred to by the values for spec.nmStateConfigLabelSelector in the InfraEnv custom resource. Create and apply your NMStateConfig custom resource, which resembles the following example. Replace values where needed: apiVersion: agent-install.openshift.io/v1beta1 kind: NMStateConfig metadata: name: <mynmstateconfig> namespace: <demo-worker4> labels: demo-nmstate-label: <value> spec: config: interfaces: - name: eth0 type: ethernet state: up mac-address: 02:00:00:80:12:14 ipv4: enabled: true address: - ip: 192.168.111.30 prefix-length: 24 dhcp: false - name: eth1 type: ethernet state: up mac-address: 02:00:00:80:12:15 ipv4: enabled: true address: - ip: 192.168.140.30 prefix-length: 24 dhcp: false dns-resolver: config: server: - 192.168.126.1 routes: config: - destination: 0.0.0.0/0 -hop-address: 192.168.111.1 -hop-interface: eth1 table-id: 254 - destination: 0.0.0.0/0 -hop-address: 192.168.140.1 -hop-interface: eth1 table-id: 254 interfaces: - name: "eth0" macAddress: "02:00:00:80:12:14" - name: "eth1" macAddress: "02:00:00:80:12:15" Note: You must include the demo-nmstate-label label name and value in the InfraEnv resource spec.nmStateConfigLabelSelector.matchLabels field. 1.6.4.9.3.7. Create the InfraEnv custom resource The InfraEnv custom resource provides the configuration to create the discovery ISO. Within this custom resource, you identify values for proxy settings, ignition overrides, and specify NMState labels. The value of spec.nmStateConfigLabelSelector in this custom resource references the NMStateConfig custom resource. Note: If you plan to include the optional NMStateConfig custom resource, you must reference it in the InfraEnv custom resource. If you create the InfraEnv custom resource before you create the NMStateConfig custom resource edit the InfraEnv custom resource to reference the NMStateConfig custom resource and download the ISO after the reference is added. Create and apply the following custom resource: apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv metadata: name: myinfraenv namespace: demo-worker4 spec: clusterRef: name: single-node 1 namespace: demo-worker4 2 pullSecretRef: name: pull-secret sshAuthorizedKey: <your_public_key_here> nmStateConfigLabelSelector: matchLabels: demo-nmstate-label: value proxy: httpProxy: http://USERNAME:PASSWORD@proxy.example.com:PORT httpsProxy: https://USERNAME:PASSWORD@proxy.example.com:PORT noProxy: .example.com,172.22.0.0/24,10.10.0.0/24 1 Replace the clusterDeployment resource name from Create the ClusterDeployment . 2 Replace the clusterDeployment resource namespace from Create the ClusterDeployment . 1.6.4.9.3.7.1. InfraEnv field table Field Optional or required Description sshAuthorizedKey Optional You can specify your SSH public key, which enables you to access the host when it is booted from the discovery ISO image. nmStateConfigLabelSelector Optional Consolidates advanced network configuration such as static IPs, bridges, and bonds for the hosts. The host network configuration is specified in one or more NMStateConfig resources with labels you choose. The nmStateConfigLabelSelector property is a Kubernetes label selector that matches your chosen labels. The network configuration for all NMStateConfig labels that match this label selector is included in the Discovery Image. When you boot, each host compares each configuration to its network interfaces and applies the appropriate configuration. proxy Optional You can specify proxy settings required by the host during discovery in the proxy section. Note: When provisioning with IPv6, you cannot define a CIDR address block in the noProxy settings. You must define each address separately. 1.6.4.9.3.8. Boot the host from the discovery image The remaining steps explain how to boot the host from the discovery ISO image that results from the procedures. Download the discovery image from the namespace by running the following command: Move the discovery image to virtual media, a USB drive, or another storage location and boot the host from the discovery image that you downloaded. The Agent resource is created automatically. It is registered to the cluster and represents a host that booted from a discovery image. Approve the Agent custom resource and start the installation by running the following command: Replace the agent name and UUID with your values. You can confirm that it was approved when the output of the command includes an entry for the target cluster that includes a value of true for the APPROVED parameter. 1.6.4.9.4. Additional resources For additional steps that are required when creating a cluster on the Nutanix platform with the CLI, see Adding hosts on Nutanix with the API and Nutanix post-installation configuration in the Red Hat OpenShift Container Platform documentation. For additional information about zero touch provisioning, see Clusters at the network far edge in the OpenShift Container Platform documentation. See Using image pull secrets See Creating a credential for an on-premises environment See Release images See Adding hosts to the host inventory by using the Discovery Image 1.6.4.10. Creating a cluster in a proxy environment You can create a Red Hat OpenShift Container Platform cluster when your hub cluster is connected through a proxy server. One of the following situations must be true for the cluster creation to succeed: multicluster engine operator has a private network connection with the managed cluster that you are creating, with managed cluster access to the Internet by using a proxy. The managed cluster is on an infrastructure provider, but the firewall ports enable communication from the managed cluster to the hub cluster. To create a cluster that is configured with a proxy, complete the following steps: Configure the cluster-wide-proxy setting on the hub cluster by adding the following information to your install-config YAML that is stored in your Secret: apiVersion: v1 kind: Proxy baseDomain: <domain> proxy: httpProxy: http://<username>:<password>@<proxy.example.com>:<port> httpsProxy: https://<username>:<password>@<proxy.example.com>:<port> noProxy: <wildcard-of-domain>,<provisioning-network/CIDR>,<BMC-address-range/CIDR> Replace username with the username for your proxy server. Replace password with the password to access your proxy server. Replace proxy.example.com with the path of your proxy server. Replace port with the communication port with the proxy server. Replace wildcard-of-domain with an entry for domains that should bypass the proxy. Replace provisioning-network/CIDR with the IP address of the provisioning network and the number of assigned IP addresses, in CIDR notation. Replace BMC-address-range/CIDR with the BMC address and the number of addresses, in CIDR notation. After you add the values, the settings are applied to your clusters. Provision the cluster by completing the procedure for creating a cluster. See Creating a cluster to select your provider. Note: You can only use install-config YAML when deploying your cluster. After deploying your cluster, any new changes you make to install-config YAML do not apply. To update the configuration after deployment, you must use policies. See Pod policy for more information. 1.6.4.10.1. Additional resources See Creating clusters to select your provider. See Pod policy to learn how to make configuration changes after deploying your cluster. See Cluster lifecycle introduction for more topics. Return to Creating a cluster in a proxy environment . 1.6.4.11. Configuring AgentClusterInstall proxy The AgentClusterInstall proxy fields determine the proxy settings during installation, and are used to create the cluster-wide proxy resource in the created cluster. 1.6.4.11.1. Configuring AgentClusterInstall To configure the AgentClusterInstall proxy, add the proxy settings to the AgentClusterInstall resource. See the following YAML sample with httpProxy , httpsProxy , and noProxy : apiVersion: extensions.hive.openshift.io/v1beta1 kind: AgentClusterInstall spec: proxy: httpProxy: http://<username>:<password>@<proxy.example.com>:<port> 1 httpsProxy: https://<username>:<password>@<proxy.example.com>:<port> 2 noProxy: <wildcard-of-domain>,<provisioning-network/CIDR>,<BMC-address-range/CIDR> 3 1 httpProxy is the URL of the proxy for HTTP requests. Replace the username and password values with your credentials for your proxy server. Replace proxy.example.com with the path of your proxy server. 2 httpsProxy is the URL of the proxy for HTTPS requests. Replace the values with your credentials. Replace port with the communication port with the proxy server. 3 noProxy is a comma-separated list of domains and CIDRs for which the proxy should not be used. Replace wildcard-of-domain with an entry for domains that should bypass the proxy. Replace provisioning-network/CIDR with the IP address of the provisioning network and the number of assigned IP addresses, in CIDR notation. Replace BMC-address-range/CIDR with the BMC address and the number of addresses, in CIDR notation. 1.6.5. Cluster import You can import clusters from different Kubernetes cloud providers. After you import, the target cluster becomes a managed cluster for the multicluster engine operator hub cluster. You can generally complete the import tasks anywhere that you can access the hub cluster and the target managed cluster, unless otherwise specified. A hub cluster cannot manage any other hub cluster, but can manage itself. The hub cluster is configured to automatically be imported and self-managed. You do not need to manually import the hub cluster. If you remove a hub cluster and try to import it again, you must add the local-cluster:true label to the ManagedCluster resource. Important: Cluster lifecycle now supports all providers that are certified through the Cloud Native Computing Foundation (CNCF) Kubernetes Conformance Program. Choose a vendor that is recognized by CNFC for your hybrid cloud multicluster management. See the following information about using CNFC providers: Learn how CNFC providers are certified at Certified Kubernetes Conformance . For Red Hat support information about CNFC third-party providers, see Red Hat support with third party components , or Contact Red Hat support . If you bring your own CNFC conformance certified cluster, you need to change the OpenShift Container Platform CLI oc command to the Kubernetes CLI command, kubectl . Read the following topics to learn more about importing a cluster so that you can manage it: Required user type or access level : Cluster administrator Importing an existing cluster by using the console Importing a managed cluster by using the CLI Importing a managed cluster by using agent registration Importing an on-premises Red Hat OpenShift Container Platform cluster 1.6.5.1. Importing a managed cluster by using the console After you install multicluster engine for Kubernetes operator, you are ready to import a cluster to manage. Continue reading the following topics learn how to import a managed cluster by using the console: Prerequisites Creating a new pull secret Importing a cluster Optional: Configuring the cluster API address Removing a cluster 1.6.5.1.1. Prerequisites A deployed hub cluster. If you are importing bare metal clusters, the hub cluster must be installed on a supported Red Hat OpenShift Container Platform version. A cluster you want to manage. The base64 command line tool. A defined multiclusterhub.spec.imagePullSecret if you are importing a cluster that was not created by OpenShift Container Platform. This secret might have been created when multicluster engine for Kubernetes operator was installed. See Custom image pull secret for more information about how to define this secret. Required user type or access level: Cluster administrator 1.6.5.1.2. Creating a new pull secret If you need to create a new pull secret, complete the following steps: Download your Kubernetes pull secret from cloud.redhat.com . Add the pull secret to the namespace of your hub cluster. Run the following command to create a new secret in the open-cluster-management namespace: Replace open-cluster-management with the name of the namespace of your hub cluster. The default namespace of the hub cluster is open-cluster-management . Replace path-to-pull-secret with the path to the pull secret that you downloaded. The secret is automatically copied to the managed cluster when it is imported. Ensure that a previously installed agent is deleted from the cluster that you want to import. You must remove the open-cluster-management-agent and open-cluster-management-agent-addon namespaces to avoid errors. For importing in a Red Hat OpenShift Dedicated environment, see the following notes: You must have the hub cluster deployed in a Red Hat OpenShift Dedicated environment. The default permission in Red Hat OpenShift Dedicated is dedicated-admin, but that does not contain all of the permissions to create a namespace. You must have cluster-admin permissions to import and manage a cluster with multicluster engine operator. 1.6.5.1.3. Importing a cluster You can import existing clusters from the console for each of the available cloud providers. Note: A hub cluster cannot manage a different hub cluster. A hub cluster is set up to automatically import and manage itself, so you do not have to manually import a hub cluster to manage itself. By default, the namespace is used for the cluster name and namespace, but you can change it. Important: When you create a cluster, the controller creates a namespace for the cluster and its resources. Ensure that you include only resources for that cluster instance in that namespace. Destroying the cluster deletes the namespace and all of the resources in it. Every managed cluster must be associated with a managed cluster set. If you do not assign the managed cluster to a ManagedClusterSet , the cluster is automatically added to the default managed cluster set. If you want to add the cluster to a different cluster set, you must have clusterset-admin privileges to the cluster set. If you do not have cluster-admin privileges when you are importing the cluster, you must select a cluster set on which you have clusterset-admin permissions. If you do not have the correct permissions on the specified cluster set, the cluster importing fails. Contact your cluster administrator to provide you with clusterset-admin permissions to a cluster set if you do not have cluster set options to select. If you import a OpenShift Container Platform Dedicated cluster and do not specify a vendor by adding a label for vendor=OpenShiftDedicated , or if you add a label for vendor=auto-detect , a managed-by=platform label is automatically added to the cluster. You can use this added label to identify the cluster as a OpenShift Container Platform Dedicated cluster and retrieve the OpenShift Container Platform Dedicated clusters as a group. The following table provides the available options for import mode , which specifies the method for importing the cluster: Run import commands manually After completing and submitting the information in the console, including any Red Hat Ansible Automation Platform templates, run the provided command on the target cluster to import the cluster. Enter your server URL and API token for the existing cluster Provide the server URL and API token of the cluster that you are importing. You can specify a Red Hat Ansible Automation Platform template to run when the cluster is upgraded. Provide the kubeconfig file Copy and paste the contents of the kubeconfig file of the cluster that you are importing. You can specify a Red Hat Ansible Automation Platform template to run when the cluster is upgraded. Note: You must have the Red Hat Ansible Automation Platform Resource Operator installed from OperatorHub to create and run an Ansible Automation Platform job. To configure a cluster API address, see Optional: Configuring the cluster API address . To configure your managed cluster klusterlet to run on specific nodes, see Optional: Configuring the klusterlet to run on specific nodes . 1.6.5.1.3.1. Optional: Configuring the cluster API address Complete the following steps to optionally configure the Cluster API address that is on the cluster details page by configuring the URL that is displayed in the table when you run the oc get managedcluster command: Log in to your hub cluster with an ID that has cluster-admin permissions. Configure a kubeconfig file for your targeted managed cluster. Edit the managed cluster entry for the cluster that you are importing by running the following command, replacing cluster-name with the name of the managed cluster: Add the ManagedClusterClientConfigs section to the ManagedCluster spec in the YAML file, as shown in the following example: spec: hubAcceptsClient: true managedClusterClientConfigs: - url: <https://api.new-managed.dev.redhat.com> 1 1 Replace the value of the URL with the URL that provides external access to the managed cluster that you are importing. 1.6.5.1.3.2. Optional: Configuring the klusterlet to run on specific nodes You can specify which nodes you want the managed cluster klusterlet to run on by configuring the nodeSelector and tolerations annotation for the managed cluster. Complete the following steps to configure these settings: Select the managed cluster that you want to update from the clusters page in the console. Set the YAML switch to On to view the YAML content. Note: The YAML editor is only available when importing or creating a cluster. To edit the managed cluster YAML definition after importing or creating, you must use the OpenShift Container Platform command-line interface or the Red Hat Advanced Cluster Management search feature. Add the nodeSelector annotation to the managed cluster YAML definition. The key for this annotation is: open-cluster-management/nodeSelector . The value of this annotation is a string map with JSON formatting. Add the tolerations entry to the managed cluster YAML definition. The key of this annotation is: open-cluster-management/tolerations . The value of this annotation represents a toleration list with JSON formatting. The resulting YAML might resemble the following example: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: annotations: open-cluster-management/nodeSelector: '{"dedicated":"acm"}' open-cluster-management/tolerations: '[{"key":"dedicated","operator":"Equal","value":"acm","effect":"NoSchedule"}]' You can also use a KlusterletConfig to configure the nodeSelector and tolerations for the managed cluster. Complete the following steps to configure these settings: Note: If you use a KlusterletConfig , the managed cluster uses the configuration in the KlusterletConfig settings instead of the settings in the managed cluster annotation. Apply the following sample YAML content. Replace value where needed: apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: <klusterletconfigName> spec: nodePlacement: nodeSelector: dedicated: acm tolerations: - key: dedicated operator: Equal value: acm effect: NoSchedule Add the agent.open-cluster-management.io/klusterlet-config: `<klusterletconfigName> annotation to the managed cluster, replacing <klusterletconfigName> with the name of your KlusterletConfig . 1.6.5.1.4. Removing an imported cluster Complete the following procedure to remove an imported cluster and the open-cluster-management-agent-addon that was created on the managed cluster. On the Clusters page, click Actions > Detach cluster to remove your cluster from management. Note: If you attempt to detach the hub cluster, which is named local-cluster , be aware that the default setting of disableHubSelfManagement is false . This setting causes the hub cluster to reimport itself and manage itself when it is detached and it reconciles the MultiClusterHub controller. It might take hours for the hub cluster to complete the detachment process and reimport. If you want to reimport the hub cluster without waiting for the processes to finish, you can run the following command to restart the multiclusterhub-operator pod and reimport faster: You can change the value of the hub cluster to not import automatically by changing the disableHubSelfManagement value to true . For more information, see the disableHubSelfManagement topic. 1.6.5.1.4.1. Additional resources See Custom image pull secret for more information about how to define a custom image pull secret. See the disableHubSelfManagement topic. 1.6.5.2. Importing a managed cluster by using the CLI After you install multicluster engine for Kubernetes operator, you are ready to import a cluster and manage it by using the Red Hat OpenShift Container Platform CLI. Continue reading the following topics to learn how to import a managed cluster with the CLI by using the auto import secret, or by using manual commands. Prerequisites Supported architectures Preparing cluster import Importing a cluster by using the auto import secret Importing a cluster manually Importing the klusterlet add-on Removing an imported cluster by using the CLI Important: A hub cluster cannot manage a different hub cluster. A hub cluster is set up to automatically import and manage itself as a local cluster . You do not have to manually import a hub cluster to manage itself. If you remove a hub cluster and try to import it again, you need to add the local-cluster:true label. 1.6.5.2.1. Prerequisites A deployed hub cluster. If you are importing bare metal clusters, the hub cluster must be installed on a supported OpenShift Container Platform version. A separate cluster you want to manage. The OpenShift Container Platform CLI. See Getting started with the OpenShift CLI for information about installing and configuring the OpenShift Container Platform CLI. A defined multiclusterhub.spec.imagePullSecret if you are importing a cluster that was not created by OpenShift Container Platform. This secret might have been created when multicluster engine for Kubernetes operator was installed. See Custom image pull secret for more information about how to define this secret. 1.6.5.2.2. Supported architectures Linux (x86_64, s390x, ppc64le) macOS 1.6.5.2.3. Preparing for cluster import Before importing a managed cluster by using the CLI, you must complete the following steps: Log in to your hub cluster by running the following command: Run the following command on the hub cluster to create the project and namespace. The cluster name that is defined in <cluster_name> is also used as the cluster namespace in the YAML file and commands: Important: The cluster.open-cluster-management.io/managedCluster label is automatically added to and removed from a managed cluster namespace. Do not manually add it to or remove it from a managed cluster namespace. Create a file named managed-cluster.yaml with the following example content: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: name: <cluster_name> labels: cloud: auto-detect vendor: auto-detect spec: hubAcceptsClient: true When the values for cloud and vendor are set to auto-detect , Red Hat Advanced Cluster Management detects the cloud and vendor types automatically from the cluster that you are importing. You can optionally replace the values for auto-detect with with the cloud and vendor values for your cluster. See the following example: cloud: Amazon vendor: OpenShift Apply the YAML file to the ManagedCluster resource by running the following command: You can now continue with either Importing the cluster by using the auto import secret or Importing the cluster manually . 1.6.5.2.4. Importing a cluster by using the auto import secret To import a managed cluster by using the auto import secret, you must create a secret that contains either a reference to the kubeconfig file of the cluster, or the kube API server and token pair of the cluster. Complete the following steps to import a cluster by using the auto import secret: Retrieve the kubeconfig file, or the kube API server and token, of the managed cluster that you want to import. See the documentation for your Kubernetes cluster to learn where to locate your kubeconfig file or your kube API server and token. Create the auto-import-secret.yaml file in the USD{CLUSTER_NAME} namespace. Create a YAML file named auto-import-secret.yaml by using content that is similar to the following template: apiVersion: v1 kind: Secret metadata: name: auto-import-secret namespace: <cluster_name> stringData: autoImportRetry: "5" # If you are using the kubeconfig file, add the following value for the kubeconfig file # that has the current context set to the cluster to import: kubeconfig: |- <kubeconfig_file> # If you are using the token/server pair, add the following two values instead of # the kubeconfig file: token: <Token to access the cluster> server: <cluster_api_url> type: Opaque Apply the YAML file in the <cluster_name> namespace by running the following command: Note: By default, the auto import secret is used one time and deleted when the import process completes. If you want to keep the auto import secret, add managedcluster-import-controller.open-cluster-management.io/keeping-auto-import-secret to the secret. You can add it by running the following command: Validate the JOINED and AVAILABLE status for your imported cluster. Run the following command from the hub cluster: Log in to the managed cluster by running the following command on the cluster: You can validate the pod status on the cluster that you are importing by running the following command: You can now continue with Importing the klusterlet add-on . 1.6.5.2.5. Importing a cluster manually Important: The import command contains pull secret information that is copied to each of the imported managed clusters. Anyone who can access the imported clusters can also view the pull secret information. Complete the following steps to import a managed cluster manually: Obtain the klusterlet-crd.yaml file that was generated by the import controller on your hub cluster by running the following command: Obtain the import.yaml file that was generated by the import controller on your hub cluster by running the following command: Proceed with the following steps in the cluster that you are importing: Log in to the managed cluster that you are importing by entering the following command: Apply the klusterlet-crd.yaml that you generated in step 1 by running the following command: Apply the import.yaml file that you previously generated by running the following command: You can validate the JOINED and AVAILABLE status for the managed cluster that you are importing by running the following command from the hub cluster: You can now continue with Importing the klusterlet add-on . 1.6.5.2.6. Importing the klusterlet add-on Implement the KlusterletAddonConfig klusterlet add-on configuration to enable other add-ons on your managed clusters. Create and apply the configuration file by completing the following steps: Create a YAML file that is similar to the following example: apiVersion: agent.open-cluster-management.io/v1 kind: KlusterletAddonConfig metadata: name: <cluster_name> namespace: <cluster_name> spec: applicationManager: enabled: true certPolicyController: enabled: true policyController: enabled: true searchCollector: enabled: true Save the file as klusterlet-addon-config.yaml . Apply the YAML by running the following command: Add-ons are installed after the managed cluster status you are importing is AVAILABLE . You can validate the pod status of add-ons on the cluster you are importing by running the following command: 1.6.5.2.7. Removing an imported cluster by using the command line interface To remove a managed cluster by using the command line interface, run the following command: Replace <cluster_name> with the name of the cluster. 1.6.5.3.

This secret might have been created when multicluster engine for Kubernetes operator was installed. See Custom image pull secret for more information about how to define this secret. If you need to create a new secret, see Creating a new pull secret . 1.6.5.3.2. Supported architectures Linux (x86_64, s390x, ppc64le) macOS 1.6.5.3.3. Importing a cluster To import a managed cluster by using the agent registration endpoint, complete the following steps: Get the agent registration server URL by running the following command on the hub cluster: Note: If your hub cluster is using a cluster-wide-proxy, make sure that you are using the URL that managed cluster can access. Get the cacert by running the following command: Note: If you are not using the kube-root-ca issued endpoint, use the public agent-registration API endpoint CA instead of the kube-root-ca CA. Get the token for the agent registration sever to authorize by applying the following YAML content: apiVersion: v1 kind: ServiceAccount metadata: name: managed-cluster-import-agent-registration-sa namespace: multicluster-engine --- apiVersion: v1 kind: Secret type: kubernetes.io/service-account-token metadata: name: managed-cluster-import-agent-registration-sa-token namespace: multicluster-engine annotations: kubernetes.io/service-account.name: "managed-cluster-import-agent-registration-sa" --- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRole metadata: name: managedcluster-import-controller-agent-registration-client rules: - nonResourceURLs: ["/agent-registration/*"] verbs: ["get"] --- kind: ClusterRoleBinding apiVersion: rbac.authorization.k8s.io/v1 metadata: name: managed-cluster-import-agent-registration roleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: managedcluster-import-controller-agent-registration-client subjects: - kind: ServiceAccount name: managed-cluster-import-agent-registration-sa namespace: multicluster-engine Run the following command to export the token: Enable the automatic approval and patch the content to cluster-manager by running the following command: Note: You can also disable automatic approval and manually approve certificate signing requests from managed clusters. Switch to your managed cluster and get the cacert by running the following command: Run the following command to import the managed cluster to the hub cluster: Replace <clusterName> with the name of you cluster. Optional: Replace <klusterletconfigName> with the name of your KlusterletConfig. 1.6.5.4. Importing an on-premises Red Hat OpenShift Container Platform cluster manually After you install multicluster engine for Kubernetes operator, you are ready to import a cluster to manage. You can import an existing OpenShift Container Platform cluster so that you can add additional nodes. Your hub cluster is automatically imported when you install multicluster engine operator, so you can add nodes to your hub cluster without completing the following procedure. Continue reading the following topics to learn more: Prerequisites Importing a cluster 1.6.5.4.1. Prerequisites Enable the central infrastructure management service. 1.6.5.4.2. Importing a cluster Complete the following steps to import an OpenShift Container Platform cluster manually, without a static network or a bare metal host, and prepare it for adding nodes: Create a namespace for the OpenShift Container Platform cluster that you want to import by applying the following YAML content: apiVersion: v1 kind: Namespace metadata: name: managed-cluster Make sure that a ClusterImageSet matching the OpenShift Container Platform cluster you are importing exists by applying the following YAML content: apiVersion: hive.openshift.io/v1 kind: ClusterImageSet metadata: name: openshift-v4.11.18 spec: releaseImage: quay.io/openshift-release-dev/ocp-release@sha256:22e149142517dfccb47be828f012659b1ccf71d26620e6f62468c264a7ce7863 Add your pull secret to access the image by applying the following YAML content: apiVersion: v1 kind: Secret type: kubernetes.io/dockerconfigjson metadata: name: pull-secret namespace: managed-cluster stringData: .dockerconfigjson: <pull-secret-json> 1 1 Replace <pull-secret-json> with your pull secret JSON. Copy the kubeconfig from your OpenShift Container Platform cluster to the hub cluster. Get the kubeconfig from your OpenShift Container Platform cluster by running the following command. Make sure that kubeconfig is set as the cluster being imported: Note: If your cluster API is accessed through a custom domain, you must first edit this kubeconfig by adding your custom certificates in the certificate-authority-data field and by changing the server field to match your custom domain. Copy the kubeconfig to the hub cluster by running the following command. Make sure that kubeconfig is set as your hub cluster: Create an AgentClusterInstall custom resource by applying the following YAML content. Replace values where needed: apiVersion: extensions.hive.openshift.io/v1beta1 kind: AgentClusterInstall metadata: name: <your-cluster-name> 1 namespace: <managed-cluster> spec: networking: userManagedNetworking: true clusterDeploymentRef: name: <your-cluster> imageSetRef: name: openshift-v4.11.18 provisionRequirements: controlPlaneAgents: 2 sshPublicKey: <""> 3 1 Choose a name for your cluster. 2 Use 1 if you are using a single-node OpenShift cluster. Use 3 if you are using a multinode cluster. 3 Add the optional sshPublicKey field to log in to nodes for troubleshooting. Create a ClusterDeployment by applying the following YAML content. Replace values where needed: apiVersion: hive.openshift.io/v1 kind: ClusterDeployment metadata: name: <your-cluster-name> 1 namespace: managed-cluster spec: baseDomain: <redhat.com> 2 installed: <true> 3 clusterMetadata: adminKubeconfigSecretRef: name: <your-cluster-name-admin-kubeconfig> 4 clusterID: <""> 5 infraID: <""> 6 clusterInstallRef: group: extensions.hive.openshift.io kind: AgentClusterInstall name: your-cluster-name-install version: v1beta1 clusterName: your-cluster-name platform: agentBareMetal: pullSecretRef: name: pull-secret 1 Choose a name for your cluster. 2 Make sure baseDomain matches the domain you are using for your OpenShift Container Platform cluster. 3 Set to true to automatically import your OpenShift Container Platform cluster as a production environment cluster. 4 Reference the kubeconfig you created in step 4. 5 6 Leave clusterID and infraID empty in production environments. Add an InfraEnv custom resource to discover new hosts to add to your cluster by applying the following YAML content. Replace values where needed: Note: The following example might require additional configuration if you are not using a static IP address. apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv metadata: name: your-infraenv namespace: managed-cluster spec: clusterRef: name: your-cluster-name namespace: managed-cluster pullSecretRef: name: pull-secret sshAuthorizedKey: "" Table 1.7. InfraEnv field table Field Optional or required Description clusterRef Optional The clusterRef field is optional if you are using late binding. If you are not using late binding, you must add the clusterRef . sshAuthorizedKey Optional Add the optional sshAuthorizedKey field to log in to nodes for troubleshooting. If the import is successful, a URL to download an ISO file appears. Download the ISO file by running the following command, replacing <url> with the URL that appears: Note: You can automate host discovery by using bare metal host. Optional: If you want to use Red Hat Advanced Cluster Management features, such as policies, on your OpenShift Container Platform cluster, create a ManagedCluster resource. Make sure that the name of your ManagedCluster resource matches the name of your ClusterDeplpoyment resource. If you are missing the ManagedCluster resource, your cluster status is detached in the console. 1.6.5.5. Specifying image registry on managed clusters for import You might need to override the image registry on the managed clusters that you are importing. You can do this by creating a ManagedClusterImageRegistry custom resource definition. The ManagedClusterImageRegistry custom resource definition is a namespace-scoped resource. The ManagedClusterImageRegistry custom resource definition specifies a set of managed clusters for a Placement to select, but needs different images from the custom image registry. After the managed clusters are updated with the new images, the following label is added to each managed cluster for identification: open-cluster-management.io/image-registry=<namespace>.<managedClusterImageRegistryName> . The following example shows a ManagedClusterImageRegistry custom resource definition: apiVersion: imageregistry.open-cluster-management.io/v1alpha1 kind: ManagedClusterImageRegistry metadata: name: <imageRegistryName> namespace: <namespace> spec: placementRef: group: cluster.open-cluster-management.io resource: placements name: <placementName> 1 pullSecret: name: <pullSecretName> 2 registries: 3 - mirror: <mirrored-image-registry-address> source: <image-registry-address> - mirror: <mirrored-image-registry-address> source: <image-registry-address> 1 Replace with the name of a Placement in the same namespace that selects a set of managed clusters. 2 Replace with the name of the pull secret that is used to pull images from the custom image registry. 3 List the values for each of the source and mirror registries. Replace the mirrored-image-registry-address and image-registry-address with the value for each of the mirror and source values of the registries. Example 1: To replace the source image registry named registry.redhat.io/rhacm2 with localhost:5000/rhacm2 , and registry.redhat.io/multicluster-engine with localhost:5000/multicluster-engine , use the following example: registries: - mirror: localhost:5000/rhacm2/ source: registry.redhat.io/rhacm2 - mirror: localhost:5000/multicluster-engine source: registry.redhat.io/multicluster-engine Example 2: To replace the source image, registry.redhat.io/rhacm2/registration-rhel8-operator with localhost:5000/rhacm2-registration-rhel8-operator , use the following example: registries: - mirror: localhost:5000/rhacm2-registration-rhel8-operator source: registry.redhat.io/rhacm2/registration-rhel8-operator Important: If you are importing a managed cluster by using agent registration, you must create a KlusterletConfig that contains image registries. See the following example. Replace values where needed: apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: <klusterletconfigName> spec: pullSecret: namespace: <pullSecretNamespace> name: <pullSecretName> registries: - mirror: <mirrored-image-registry-address> source: <image-registry-address> - mirror: <mirrored-image-registry-address> source: <image-registry-address> See Importing a managed cluster by using the agent registration endpoint to learn more. 1.6.5.5.1. Importing a cluster that has a ManagedClusterImageRegistry Complete the following steps to import a cluster that is customized with a ManagedClusterImageRegistry custom resource definition: Create a pull secret in the namespace where you want your cluster to be imported. For these steps, the namespace is myNamespace . Create a Placement in the namespace that you created. apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: myPlacement namespace: myNamespace spec: clusterSets: - myClusterSet tolerations: - key: "cluster.open-cluster-management.io/unreachable" operator: Exists Note: The unreachable toleration is required for the Placement to be able to select the cluster. Create a ManagedClusterSet resource and bind it to your namespace. apiVersion: cluster.open-cluster-management.io/v1beta2 kind: ManagedClusterSet metadata: name: myClusterSet --- apiVersion: cluster.open-cluster-management.io/v1beta2 kind: ManagedClusterSetBinding metadata: name: myClusterSet namespace: myNamespace spec: clusterSet: myClusterSet Create the ManagedClusterImageRegistry custom resource definition in your namespace. apiVersion: imageregistry.open-cluster-management.io/v1alpha1 kind: ManagedClusterImageRegistry metadata: name: myImageRegistry namespace: myNamespace spec: placementRef: group: cluster.open-cluster-management.io resource: placements name: myPlacement pullSecret: name: myPullSecret registry: myRegistryAddress Import a managed cluster from the console and add it to a managed cluster set. Copy and run the import commands on the managed cluster after the open-cluster-management.io/image-registry=myNamespace.myImageRegistry label is added to the managed cluster. 1.6.6. Accessing your cluster To access an Red Hat OpenShift Container Platform cluster that was created and is managed, complete the following steps: From the console, navigate to Infrastructure > Clusters and select the name of the cluster that you created or want to access. Select Reveal credentials to view the user name and password for the cluster. Note these values to use when you log in to the cluster. Note: The Reveal credentials option is not available for imported clusters. Select Console URL to link to the cluster. Log in to the cluster by using the user ID and password that you found in step three. 1.6.7. Scaling managed clusters For clusters that you created, you can customize and resize your managed cluster specifications, such as virtual machine sizes and number of nodes. See the following option if you are using installer-provisioned infrastructure for cluster deployment: Scaling with MachinePool See the following options if you are using central infrastructure management for cluster deployment: Adding worker nodes to OpenShift Container Platform clusters Adding control plane nodes to managed clusters 1.6.7.1. Scaling with MachinePool For clusters that you provision with multicluster engine operator, a MachinePool resource is automatically created for you. You can further customize and resize your managed cluster specifications, such as virtual machine sizes and number of nodes, by using MachinePool . Using the MachinePool resource is not supported for bare metal clusters. A MachinePool resource is a Kubernetes resource on the hub cluster that groups the MachineSet resources together on the managed cluster. The MachinePool resource uniformly configures a set of machine resources, including zone configurations, instance type, and root storage. With MachinePool , you can manually configure the desired number of nodes or configure autoscaling of nodes on the managed cluster. 1.6.7.1.1. Configure autoscaling Configuring autoscaling provides the flexibility of your cluster to scale as needed to lower your cost of resources by scaling down when traffic is low, and by scaling up to ensure that there are enough resources when there is a higher demand for resources. To enable autoscaling on your MachinePool resources using the console, complete the following steps: In the navigation, select Infrastructure > Clusters . Click the name of your target cluster and select the Machine pools tab. From the machine pools page, select Enable autoscale from the Options menu for the target machine pool. Select the minimum and maximum number of machine set replicas. A machine set replica maps directly to a node on the cluster. The changes might take several minutes to reflect on the console after you click Scale . You can view the status of the scaling operation by clicking View machines in the notification of the Machine pools tab. To enable autoscaling on your MachinePool resources using the command line, complete the following steps: Enter the following command to view your list of machine pools, replacing managed-cluster-namespace with the namespace of your target managed cluster. Enter the following command to edit the YAML file for the machine pool: Replace MachinePool-resource-name with the name of your MachinePool resource. Replace managed-cluster-namespace with the name of the namespace of your managed cluster. Delete the spec.replicas field from the YAML file. Add the spec.autoscaling.minReplicas setting and spec.autoscaling.maxReplicas fields to the resource YAML. Add the minimum number of replicas to the minReplicas setting. Add the maximum number of replicas into the maxReplicas setting. Save the file to submit the changes. 1.6.7.1.2. Disabling autoscaling You can disable autoscaling by using the console or the command line. To disable autoscaling by using the console, complete the following steps: In the navigation, select Infrastructure > Clusters . Click the name of your target cluster and select the Machine pools tab. From the machine pools page, select Disable autoscale from the Options menu for the target machine pool. Select the number of machine set replicas that you want. A machine set replica maps directly with a node on the cluster. It might take several minutes to display in the console after you click Scale . You can view the status of the scaling by clicking View machines in the notification on the Machine pools tab. To disable autoscaling by using the command line, complete the following steps: Enter the following command to view your list of machine pools: Replace managed-cluster-namespace with the namespace of your target managed cluster. Enter the following command to edit the YAML file for the machine pool: Replace name-of-MachinePool-resource with the name of your MachinePool resource. Replace namespace-of-managed-cluster with the name of the namespace of your managed cluster. Delete the spec.autoscaling field from the YAML file. Add the spec.replicas field to the resource YAML. Add the number of replicas to the replicas setting. Save the file to submit the changes. 1.6.7.1.3. Enabling manual scaling You can scale manually from the console and from the command line. 1.6.7.1.3.1. Enabling manual scaling with the console To scale your MachinePool resources using the console, complete the following steps: Disable autoscaling for your MachinePool if it is enabled. See the steps. From the console, click Infrastructure > Clusters . Click the name of your target cluster and select the Machine pools tab. From the machine pools page, select Scale machine pool from the Options menu for the targeted machine pool. Select the number of machine set replicas that you want. A machine set replica maps directly with a node on the cluster. Changes might take several minutes to reflect on the console after you click Scale . You can view the status of the scaling operation by clicking View machines from the notification of the Machine pools tab. 1.6.7.1.3.2. Enabling manual scaling with the command line To scale your MachinePool resources by using the command line, complete the following steps: Enter the following command to view your list of machine pools, replacing <managed-cluster-namespace> with the namespace of your target managed cluster namespace: Enter the following command to edit the YAML file for the machine pool: Replace MachinePool-resource-name with the name of your MachinePool resource. Replace managed-cluster-namespace with the name of the namespace of your managed cluster. Delete the spec.autoscaling field from the YAML file. Modify the spec.replicas field in the YAML file with the number of replicas you want. Save the file to submit the changes. 1.6.7.2. Adding worker nodes to OpenShift Container Platform clusters If you are using central infrastructure management, you can customize your OpenShift Container Platform clusters by adding additional production environment nodes. Required access: Administrator Prerequisite Creating a valid kubeconfig Adding worker nodes 1.6.7.2.1. Prerequisite You must have the new CA certificates required to trust the managed cluster API. 1.6.7.2.2. Creating a valid kubeconfig Before adding production environment worker nodes to OpenShift Container Platform clusters, you must check if you have a valid kubeconfig . If the API certificates in your managed cluster changed, complete the following steps to update the kubeconfig with new CA certificates: Check if the kubeconfig for your clusterDeployment is valid by running the following commands. Replace <kubeconfig_name> with the name of your current kubeconfig and replace <cluster_name> with the name of your cluster: export <kubeconfig_name>=USD(oc get cd USD<cluster_name> -o "jsonpath={.spec.clusterMetadata.adminKubeconfigSecretRef.name}") oc extract secret/USD<kubeconfig_name> --keys=kubeconfig --to=- > original-kubeconfig oc --kubeconfig=original-kubeconfig get node If you receive the following error message, you must update your kubeconfig secret. If you receive no error message, continue to Adding worker nodes : Get the base64 encoded certificate bundle from your kubeconfig certificate-authority-data field and decode it by running the following command: echo <base64 encoded blob> | base64 --decode > decoded-existing-certs.pem Create an updated kubeconfig file by copying your original file. Run the following command and replace <new_kubeconfig_name> with the name of your new kubeconfig file: cp original-kubeconfig <new_kubeconfig_name> Append new certificates to the decoded pem by running the following command: cat decoded-existing-certs.pem new-ca-certificate.pem | openssl base64 -A Add the base64 output from the command as the value of the certificate-authority-data key in your new kubeconfig file by using a text editor. Check if the new kubeconfig is valid by querying the API with the new kubeconfig . Run the following command. Replace <new_kubeconfig_name> with the name of your new kubeconfig file: KUBECONFIG=<new_kubeconfig_name> oc get nodes If you receive a successful output, the kubeconfig is valid. Update the kubeconfig secret in the Red Hat Advanced Cluster Management hub cluster by running the following command. Replace <new_kubeconfig_name> with the name of your new kubeconfig file: oc patch secret USDoriginal-kubeconfig --type='json' -p="[{'op': 'replace', 'path': '/data/kubeconfig', 'value': 'USD(openssl base64 -A -in <new_kubeconfig_name>)'},{'op': 'replace', 'path': '/data/raw-kubeconfig', 'value': 'USD(openssl base64 -A -in <new_kubeconfig_name>)'}]" 1.6.7.2.3. Adding worker nodes If you have a valid kubeconfig , complete the following steps to add production environment worker nodes to OpenShift Container Platform clusters: Boot the machine that you want to use as a worker node from the ISO you previously downloaded. Note: Make sure that the worker node meets the requirements for an OpenShift Container Platform worker node. Wait for an agent to register after running the following command: watch -n 5 "oc get agent -n managed-cluster" If the agent registration is succesful, an agent is listed. Approve the agent for installation. This can take a few minutes. Note: If the agent is not listed, exit the watch command by pressing Ctrl and C, then log in to the worker node to troubleshoot. If you are using late binding, run the following command to associate pending unbound agents with your OpenShift Container Platform cluster. Skip to step 5 if you are not using late binding: oc get agent -n managed-cluster -ojson | jq -r '.items[] | select(.spec.approved==false) |select(.spec.clusterDeploymentName==null) | .metadata.name'| xargs oc -n managed-cluster patch -p '{"spec":{"clusterDeploymentName":{"name":"some-other-cluster","namespace":"managed-cluster"}}}' --type merge agent Approve any pending agents for installation by running the following command: oc get agent -n managed-cluster -ojson | jq -r '.items[] | select(.spec.approved==false) | .metadata.name'| xargs oc -n managed-cluster patch -p '{"spec":{"approved":true}}' --type merge agent Wait for the installation of the worker node. When the worker node installation is complete, the worker node contacts the managed cluster with a Certificate Signing Request (CSR) to start the joining process. The CSR is automatically signed. 1.6.7.3. Adding control plane nodes to managed clusters You can replace a failing control plane by adding control plane nodes to healthy or unhealthy managed clusters. Required access: Administrator 1.6.7.3.1. Adding control plane nodes to healthy managed clusters Complete the following steps to add control plane nodes to healthy managed clusters: Complete the steps in Adding worker nodes to OpenShift Container Platform clusters for your the new control plane node.

If you are using a BareMetalHost to add a node, add the following line to your BareMetalHost annotations when creating the BareMetalHost resource: bmac.agent-install.openshift.io/role: master Follow the steps in Installing a primary control plane node on a healthy cluster in the Assisted Installer for OpenShift Container Platform documentation 1.6.7.3.2. Adding control plane nodes to unhealthy managed clusters Complete the following steps to add control plane nodes to unhealthy managed clusters: Remove the agent for unhealthy control plane nodes. If you used the zero-touch provisioning flow for deployment, remove the bare metal host. Complete the steps in Adding worker nodes to OpenShift Container Platform clusters for your the new control plane node. Set the agent to master before you approve the agent by running the following command: oc patch agent <AGENT-NAME> -p '{"spec":{"role": "master"}}' --type=merge Note: CSRs are not automatically approved. Follow the steps in Installing a primary control plane node on an unhealthy cluster in the Assisted Installer for OpenShift Container Platform documentation 1.6.8. Hibernating a created cluster You can hibernate a cluster that was created using multicluster engine operator to conserve resources. A hibernating cluster requires significantly fewer resources than one that is running, so you can potentially lower your provider costs by moving clusters in and out of a hibernating state. This feature only applies to clusters that were created by multicluster engine operator in the following environments: Amazon Web Services Microsoft Azure Google Cloud Platform 1.6.8.1. Hibernate a cluster by using the console To use the console to hibernate a cluster that was created by multicluster engine operator, complete the following steps: From the navigation menu, select Infrastructure > Clusters . Ensure that the Manage clusters tab is selected. Select Hibernate cluster from the Options menu for the cluster. Note: If the Hibernate cluster option is not available, you cannot hibernate the cluster. This can happen when the cluster is imported, and not created by multicluster engine operator. The status for the cluster on the Clusters page is Hibernating when the process completes. Tip: You can hibernate multiple clusters by selecting the clusters that you want to hibernate on the Clusters page, and selecting Actions > Hibernate clusters . Your selected cluster is hibernating. 1.6.8.2. Hibernate a cluster by using the CLI To use the CLI to hibernate a cluster that was created by multicluster engine operator, complete the following steps: Enter the following command to edit the settings for the cluster that you want to hibernate: Replace name-of-cluster with the name of the cluster that you want to hibernate. Replace namespace-of-cluster with the namespace of the cluster that you want to hibernate. Change the value for spec.powerState to Hibernating . Enter the following command to view the status of the cluster: Replace name-of-cluster with the name of the cluster that you want to hibernate. Replace namespace-of-cluster with the namespace of the cluster that you want to hibernate. When the process of hibernating the cluster is complete, the value of the type for the cluster is type=Hibernating . Your selected cluster is hibernating. 1.6.8.3. Resuming normal operation of a hibernating cluster by using the console To resume normal operation of a hibernating cluster by using the console, complete the following steps: From the navigation menu, select Infrastructure > Clusters . Ensure that the Manage clusters tab is selected. Select Resume cluster from the Options menu for the cluster that you want to resume. The status for the cluster on the Clusters page is Ready when the process completes. Tip: You can resume multiple clusters by selecting the clusters that you want to resume on the Clusters page, and selecting Actions > Resume clusters . Your selected cluster is resuming normal operation. 1.6.8.4. Resuming normal operation of a hibernating cluster by using the CLI To resume normal operation of a hibernating cluster by using the CLI, complete the following steps: Enter the following command to edit the settings for the cluster: Replace name-of-cluster with the name of the cluster that you want to hibernate. Replace namespace-of-cluster with the namespace of the cluster that you want to hibernate. Change the value for spec.powerState to Running . Enter the following command to view the status of the cluster: Replace name-of-cluster with the name of the cluster that you want to hibernate. Replace namespace-of-cluster with the namespace of the cluster that you want to hibernate. When the process of resuming the cluster is complete, the value of the type for the cluster is type=Running . Your selected cluster is resuming normal operation. 1.6.9. Upgrading your cluster After you create Red Hat OpenShift Container Platform clusters that you want to manage with multicluster engine operator, you can use the multicluster engine operator console to upgrade those clusters to the latest minor version that is available in the version channel that the managed cluster uses. In a connected environment, the updates are automatically identified with notifications provided for each cluster that requires an upgrade in the console. 1.6.9.1. Prerequisites Verify that you meet all of the prerequisites for upgrading to that version. You must update the version channel on the managed cluster before you can upgrade the cluster with the console. Note: After you update the version channel on the managed cluster, the multicluster engine operator console displays the latest versions that are available for the upgrade. Your OpenShift Container Platform managed clusters must be in a Ready state. Important: You cannot upgrade Red Hat OpenShift Kubernetes Service managed clusters or OpenShift Container Platform managed clusters on Red Hat OpenShift Dedicated by using the multicluster engine operator console. 1.6.9.2. Upgrading your cluster in a connected environment To upgrade your cluster in a connected environment, complete the following steps: From the navigation menu, go to Infrastructure > Clusters . If an upgrade is available, it appears in the Distribution version column. Select the clusters in Ready state that you want to upgrade. You can only upgrade OpenShift Container Platform clusters in the console. Select Upgrade . Select the new version of each cluster. Select Upgrade . If your cluster upgrade fails, the Operator generally retries the upgrade a few times, stops, and reports the status of the failing component. In some cases, the upgrade process continues to cycle through attempts to complete the process. Rolling your cluster back to a version following a failed upgrade is not supported. Contact Red Hat support for assistance if your cluster upgrade fails. 1.6.9.3. Selecting a channel You can use the console to select a channel for your cluster upgrades on OpenShift Container Platform. After selecting a channel, you are automatically reminded of cluster upgrades that are available for both Errata versions and release versions. To select a channel for your cluster, complete the following steps: From the navigation, select Infrastructure > Clusters . Select the name of the cluster that you want to change to view the Cluster details page. If a different channel is available for the cluster, an edit icon is displayed in the Channel field. Click the Edit icon to change the setting in the field. Select a channel in the New channel field. You can find the reminders for the available channel updates in the Cluster details page of the cluster. 1.6.9.4. Upgrading a disconnected cluster You can use {cincinnati} with multicluster engine operator to upgrade clusters in a disconnected environment. In some cases, security concerns prevent clusters from being connected directly to the internet. This makes it difficult to know when upgrades are available, and how to process those upgrades. Configuring {cincinnati-short} can help. {cincinnati-short} is a separate operator and operand that monitors the available versions of your managed clusters in a disconnected environment, and makes them available for upgrading your clusters in a disconnected environment. After you configure {cincinnati-short}, it can perform the following actions: Monitor when upgrades are available for your disconnected clusters. Identify which updates are mirrored to your local site for upgrading by using the graph data file. Notify you that an upgrade is available for your cluster by using the console. The following topics explain the procedure for upgrading a disconnected cluster: Prerequisites Prepare your disconnected mirror registry Deploy the operator for {cincinnati-short} Build the graph data init container Configure certificate for the mirrored registry Deploy the {cincinnati-short} instance Override the default registry (optional) Deploy a disconnected catalog source Change the managed cluster parameter Viewing available upgrades Selecting a channel Upgrading the cluster 1.6.9.4.1. Prerequisites You must have the following prerequisites before you can use {cincinnati-short} to upgrade your disconnected clusters: A deployed hub cluster that is running on a supported OpenShift Container Platform version with restricted OLM configured. See Using Operator Lifecycle Manager on restricted networks for details about how to configure restricted OLM. Note: Make a note of the catalog source image when you configure restricted OLM. An OpenShift Container Platform cluster that is managed by the hub cluster Access credentials to a local repository where you can mirror the cluster images. See Disconnected installation mirroring for more information about how to create this repository. Note: The image for the current version of the cluster that you upgrade must always be available as one of the mirrored images. If an upgrade fails, the cluster reverts back to the version of the cluster at the time that the upgrade was attempted. 1.6.9.4.2. Prepare your disconnected mirror registry You must mirror both the image that you want to upgrade to and the current image that you are upgrading from to your local mirror registry. Complete the following steps to mirror the images: Create a script file that contains content that resembles the following example: 1 Replace /path/to/pull/secret with the path to your OpenShift Container Platform pull secret. Run the script to mirror the images, configure settings, and separate the release images from the release content. You can use the output of the last line of this script when you create your ImageContentSourcePolicy . 1.6.9.4.3. Deploy the operator for {cincinnati-short} To deploy the operator for {cincinnati-short} in your OpenShift Container Platform environment, complete the following steps: On the hub cluster, access the OpenShift Container Platform operator hub. Deploy the operator by selecting {cincinnati} Operator . Update the default values, if necessary. The deployment of the operator creates a new project named openshift-cincinnati . Wait for the installation of the operator to finish. You can check the status of the installation by entering the oc get pods command on your OpenShift Container Platform command line. Verify that the operator is in the running state. 1.6.9.4.4. Build the graph data init container {cincinnati-short} uses graph data information to determine the available upgrades. In a connected environment, {cincinnati-short} pulls the graph data information for available upgrades directly from the Cincinnati graph data GitHub repository . Because you are configuring a disconnected environment, you must make the graph data available in a local repository by using an init container . Complete the following steps to create a graph data init container : Clone the graph data Git repository by entering the following command: Create a file that contains the information for your graph data init . You can find this sample Dockerfile in the cincinnati-operator GitHub repository. The contents of the file is shown in the following sample: In this example: 1 The FROM value is the external registry where {cincinnati-short} finds the images. 2 3 The RUN commands create the directory and package the upgrade files. 4 The CMD command copies the package file to the local repository and extracts the files for an upgrade. Run the following commands to build the graph data init container : 1 Replace path_to_Dockerfile with the path to the file that you created in the step. 2 Replace USD{DISCONNECTED_REGISTRY}/cincinnati/cincinnati-graph-data-container with the path to your local graph data init container. 3 Replace /path/to/pull_secret with the path to your pull secret file. Note: You can also replace podman in the commands with docker , if you don't have podman installed. 1.6.9.4.5. Configure certificate for the mirrored registry If you are using a secure external container registry to store your mirrored OpenShift Container Platform release images, {cincinnati-short} requires access to this registry to build an upgrade graph. Complete the following steps to configure your CA certificate to work with the {cincinnati-short} pod: Find the OpenShift Container Platform external registry API, which is located in image.config.openshift.io . This is where the external registry CA certificate is stored. See Configuring additional trust stores for image registry access in the OpenShift Container Platform documentation for more information. Create a ConfigMap in the openshift-config namespace. Add your CA certificate under the key updateservice-registry . {cincinnati-short} uses this setting to locate your certificate: apiVersion: v1 kind: ConfigMap metadata: name: trusted-ca data: updateservice-registry: | -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- Edit the cluster resource in the image.config.openshift.io API to set the additionalTrustedCA field to the name of the ConfigMap that you created. Replace trusted-ca with the path to your new ConfigMap. The {cincinnati-short} Operator watches the image.config.openshift.io API and the ConfigMap you created in the openshift-config namespace for changes, then restart the deployment if the CA cert has changed. 1.6.9.4.6. Deploy the {cincinnati-short} instance When you finish deploying the {cincinnati-short} instance on your hub cluster, this instance is located where the images for the cluster upgrades are mirrored and made available to the disconnected managed cluster. Complete the following steps to deploy the instance: If you do not want to use the default namespace of the operator, which is openshift-cincinnati , create a namespace for your {cincinnati-short} instance: In the OpenShift Container Platform hub cluster console navigation menu, select Administration > Namespaces . Select Create Namespace . Add the name of your namespace, and any other information for your namespace. Select Create to create the namespace. In the Installed Operators section of the OpenShift Container Platform console, select {cincinnati} Operator . Select Create Instance in the menu. Paste the contents from your {cincinnati-short} instance. Your YAML instance might resemble the following manifest: apiVersion: cincinnati.openshift.io/v1beta2 kind: Cincinnati metadata: name: openshift-update-service-instance namespace: openshift-cincinnati spec: registry: <registry_host_name>:<port> 1 replicas: 1 repository: USD{LOCAL_REGISTRY}/ocp4/release graphDataImage: '<host_name>:<port>/cincinnati-graph-data-container' 2 1 Replace the spec.registry value with the path to your local disconnected registry for your images. 2 Replace the spec.graphDataImage value with the path to your graph data init container. This is the same value that you used when you ran the podman push command to push your graph data init container. Select Create to create the instance. From the hub cluster CLI, enter the oc get pods command to view the status of the instance creation. It might take a while, but the process is complete when the result of the command shows that the instance and the operator are running. 1.6.9.4.7. Override the default registry (optional) Note: The steps in this section only apply if you have mirrored your releases into your mirrored registry. OpenShift Container Platform has a default image registry value that specifies where it finds the upgrade packages. In a disconnected environment, you can create an override to replace that value with the path to your local image registry where you mirrored your release images. Complete the following steps to override the default registry: Create a YAML file named mirror.yaml that resembles the following content: apiVersion: operator.openshift.io/v1alpha1 kind: ImageContentSourcePolicy metadata: name: <your-local-mirror-name> 1 spec: repositoryDigestMirrors: - mirrors: - <your-registry> 2 source: registry.redhat.io 1 Replace your-local-mirror-name with the name of your local mirror. 2 Replace your-registry with the path to your local mirror repository. Note: You can find your path to your local mirror by entering the oc adm release mirror command. Using the command line of the managed cluster, run the following command to override the default registry: 1.6.9.4.8. Deploy a disconnected catalog source On the managed cluster, disable all of the default catalog sources and create a new one. Complete the following steps to change the default location from a connected location to your disconnected local registry: Create a YAML file named source.yaml that resembles the following content: apiVersion: config.openshift.io/v1 kind: OperatorHub metadata: name: cluster spec: disableAllDefaultSources: true --- apiVersion: operators.coreos.com/v1alpha1 kind: CatalogSource metadata: name: my-operator-catalog namespace: openshift-marketplace spec: sourceType: grpc image: '<registry_host_name>:<port>/olm/redhat-operators:v1' 1 displayName: My Operator Catalog publisher: grpc 1 Replace the value of spec.image with the path to your local restricted catalog source image. On the command line of the managed cluster, change the catalog source by running the following command: 1.6.9.4.9. Change the managed cluster parameter Update the ClusterVersion resource information on the managed cluster to change the default location from where it retrieves its upgrades. From the managed cluster, confirm that the ClusterVersion upstream parameter is currently the default public {cincinnati-short} operand by entering the following command: The returned content might resemble the following content with 4.x set as the supported version: apiVersion: v1 items: - apiVersion: config.openshift.io/v1 kind: ClusterVersion [..] spec: channel: stable-4.x upstream: https://api.openshift.com/api/upgrades_info/v1/graph From the hub cluster, identify the route URL to the {cincinnati-short} operand by entering the following command: Note the returned value for later steps. On the command line of the managed cluster, edit the ClusterVersion resource by entering the following command: Replace the value of spec.channel with your new version. Replace the value of spec.upstream with the path to your hub cluster {cincinnati-short} operand. You can complete the following steps to determine the path to your operand: Run the following command on the hub cluster: Find the path to cincinnati . The path the operand is the value in the HOST/PORT field. On the command line of the managed cluster, confirm that the upstream parameter in the ClusterVersion is updated with the local hub cluster {cincinnati-short} URL by entering the following command: The results resemble the following content: apiVersion: v1 items: - apiVersion: config.openshift.io/v1 kind: ClusterVersion [..] spec: channel: stable-4.x upstream: https://<hub-cincinnati-uri>/api/upgrades_info/v1/graph 1.6.9.4.10. Viewing available upgrades On the Clusters page, the Distribution version of the cluster indicates that there is an upgrade available, if there is an upgrade in the disconnected registry. You can view the available upgrades by selecting the cluster and selecting Upgrade clusters from the Actions menu. If the optional upgrade paths are available, the available upgrades are listed. Note: No available upgrade versions are shown if the current version is not mirrored into the local image repository. 1.6.9.4.11. Selecting a channel You can use the console to select a channel for your cluster upgrades on OpenShift Container Platform version 4.6 or later. Those versions must be available on the mirror registry. Complete the steps in Selecting a channel to specify a channel for your upgrades. 1.6.9.4.12. Upgrading the cluster After you configure the disconnected registry, multicluster engine operator and {cincinnati-short} use the disconnected registry to determine if upgrades are available. If no available upgrades are displayed, make sure that you have the release image of the current level of the cluster and at least one later level mirrored in the local repository. If the release image for the current version of the cluster is not available, no upgrades are available. On the Clusters page, the Distribution version of the cluster indicates that there is an upgrade available, if there is an upgrade in the disconnected registry. You can upgrade the image by clicking Upgrade available and selecting the version for the upgrade. The managed cluster is updated to the selected version. If your cluster upgrade fails, the Operator generally retries the upgrade a few times, stops, and reports the status of the failing component. In some cases, the upgrade process continues to cycle through attempts to complete the process. Rolling your cluster back to a version following a failed upgrade is not supported. Contact Red Hat support for assistance if your cluster upgrade fails. 1.6.10. Using cluster proxy add-ons In some environments, a managed cluster is behind a firewall and cannot be accessed directly by the hub cluster. To gain access, you can set up a proxy add-on to access the kube-apiserver of the managed cluster to provide a more secure connection. Important: There must not be a cluster-wide proxy configuration on your hub cluster. Required access: Editor To configure a cluster proxy add-on for a hub cluster and a managed cluster, complete the following steps: Configure the kubeconfig file to access the managed cluster kube-apiserver by completing the following steps: Provide a valid access token for the managed cluster. Note: : You can use the corresponding token of the service account. You can also use the default service account that is in the default namespace. Export the kubeconfig file of the managed cluster by running the following command: Add a role to your service account that allows it to access pods by running the following commands: Run the following command to locate the secret of the service account token: Replace default-token with the name of your secret. Run the following command to copy the token: Replace default-token with the name of your secret. Configure the kubeconfig file on the Red Hat Advanced Cluster Management hub cluster. Export the current kubeconfig file on the hub cluster by running the following command: Modify the server file with your editor. This example uses commands when using sed . Run alias sed=gsed , if you are using OSX. Delete the original user credentials by entering the following commands: Add the token of the service account: List all of the pods on the target namespace of the target managed cluster by running the following command: Replace the default namespace with the namespace that you want to use. Access other services on the managed cluster. This feature is available when the managed cluster is a Red Hat OpenShift Container Platform cluster. The service must use service-serving-certificate to generate server certificates: From the managed cluster, use the following service account token: From the hub cluster, convert the certificate authority to a file by running the following command: Get Prometheus metrics of the managed cluster by using the following commands: 1.6.10.1. Configuring proxy settings for cluster proxy add-ons You can configure the proxy settings for cluster proxy add-ons to allow a managed cluster to communicate with the hub cluster through a HTTP and HTTPS proxy server. You might need to configure the proxy settings if the cluster proxy add-on agent requires access to the hub cluster through the proxy server. To configure the proxy settings for the cluster proxy add-on, complete the following steps: Create an AddOnDeploymentConfig resource on your hub cluster and add the spec.proxyConfig parameter. See the following example: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: AddOnDeploymentConfig metadata: name: <name> 1 namespace: <namespace> 2 spec: agentInstallNamespace: open-cluster-managment-agent-addon proxyConfig: httpsProxy: "http://<username>:<password>@<ip>:<port>" 3 noProxy: ".cluster.local,.svc,172.30.0.1" 4 caBundle: <value> 5 1 Add your add-on deployment config name. 2 Add your managed cluster name. 3 Specify either a HTTP proxy or a HTTPS proxy. 4 Add the IP address of the kube-apiserver . To get the IP address, run following command on your managed cluster: oc -n default describe svc kubernetes | grep IP: 5 If you specify a HTTPS proxy in the httpsProxy field, set the proxy server CA bundle. Update the ManagedClusterAddOn resource by referencing the AddOnDeploymentConfig resource that you created. See the following example: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: ManagedClusterAddOn metadata: name: cluster-proxy namespace: <namespace> 1 spec: installNamespace: open-cluster-managment-addon configs: group: addon.open-cluster-management.io resource: AddonDeploymentConfig name: <name> 2 namespace: <namespace> 3 1 Add your managed cluster name. 2 Add your add-on deployment config name. 3 Add your managed cluster name. Verify the proxy settings by checking if the cluster proxy agent pod in the open-cluster-managment-addon namespace has HTTPS_PROXY or NO_PROXY environment variables on the managed cluster. 1.6.11. Configuring Ansible Automation Platform tasks to run on managed clusters multicluster engine operator is integrated with Red Hat Ansible Automation Platform so that you can create prehook and posthook Ansible job instances that occur before or after creating or upgrading your clusters. Configuring prehook and posthook jobs for cluster destroy, and cluster scale actions are not supported. Required access: Cluster administrator Prerequisites Configuring an Automation template to run on a cluster by using the console Creating an Automation template Viewing the status of an Ansible job Pushing custom labels from the ClusterCurator resource to the automation job pod Using the ClusterCurator for Extended Update Support (EUS) upgrades 1.6.11.1. Prerequisites You must meet the following prerequisites to run Automation templates on your clusters: Install OpenShift Container Platform. Install the Ansible Automation Platform Resource Operator to connect Ansible jobs to the lifecycle of Git subscriptions. For best results when using the Automation template to launch Ansible Automation Platform jobs, the Ansible Automation Platform job template should be idempotent when it is run. You can find the Ansible Automation Platform Resource Operator in the OpenShift Container Platform OperatorHub . 1.6.11.2. Configuring an Automation template to run on a cluster by using the console You can specify the Automation template that you want to use for a cluster when you create the cluster, when you import the cluster, or after you create the cluster. To specify the template when creating or importing a cluster, select the Ansible template that you want to apply to the cluster in the Automation step. If there are no Automation templates, click Add automation template to create one. To specify the template after creating a cluster, click Update automation template in the action menu of an existing cluster. You can also use the Update automation template option to update an existing automation template. 1.6.11.3. Creating an Automation template To initiate an Ansible job with a cluster installation or upgrade, you must create an Automation template to specify when you want the jobs to run. They can be configured to run before or after the cluster installs or upgrades. To specify the details about running the Ansible template while creating a template, complete the steps in the console: Select Infrastructure > Automation from the navigation. Select the applicable path for your situation: If you want to create a new template, click Create Ansible template and continue with step 3. If you want to modify an existing template, click Edit template from the Options menu of the template that you want to modify and continue with step 5. Enter a unique name for your template, which contains lowercase alphanumeric characters or a hyphen (-). Select the credential that you want to use for the new template. After you select a credential, you can select an Ansible inventory to use for all the jobs. To link an Ansible credential to an Ansible template, complete the following steps: From the navigation, select Automation . Any template in the list of templates that is not linked to a credential contains a Link to credential icon that you can use to link the template to an existing credential. Only the credentials in the same namespace as the template are displayed. If there are no credentials that you can select, or if you do not want to use an existing credential, select Edit template from the Options menu for the template that you want to link. Click Add credential and complete the procedure in Creating a credential for Ansible Automation Platform if you have to create your credential. After you create your credential in the same namespace as the template, select the credential in the Ansible Automation Platform credential field when you edit the template. If you want to initiate any Ansible jobs before the cluster is installed, select Add an Automation template in the Pre-install Automation templates section. Select between a Job template or a Workflow job template in the modal that appears. You can also add job_tags , skip_tags , and workflow types. Use the Extra variables field to pass data to the AnsibleJob resource in the form of key=value pairs. Special keys cluster_deployment and install_config are passed automatically as extra variables. They contain general information about the cluster and details about the cluster installation configuration. Select the name of the prehook and posthook Ansible jobs to add to the installation or upgrade of the cluster. Drag the Ansible jobs to change the order, if necessary. Repeat steps 5 - 7 for any Automation templates that you want to initiate after the cluster is installed in the Post-install Automation templates section, the Pre-upgrade Automation templates section, and the Post-upgrade Automation templates section. When upgrading a cluster, you can use the Extra variables field to pass data to the AnsibleJob resource in the form of key=value pairs. In addition to the cluster_deployment and install_config special keys, the cluster_info special key is also passed automatically as an extra variable containing data from the ManagedClusterInfo resource. Your Ansible template is configured to run on clusters that specify this template when the designated actions occur. 1.6.11.4. Viewing the status of an Ansible job You can view the status of a running Ansible job to ensure that it started, and is running successfully. To view the current status of a running Ansible job, complete the following steps: In the menu, select Infrastructure > Clusters to access the Clusters page. Select the name of the cluster to view its details. View the status of the last run of the Ansible job on the cluster information. The entry shows one of the following statuses: When an install prehook or posthook job fails, the cluster status shows Failed . When an upgrade prehook or posthook job fails, a warning is displayed in the Distribution field that the upgrade failed. 1.6.11.5. Running a failed Ansible job again You can retry an upgrade from the Clusters page if the cluster prehook or posthook failed. To save time, you can also run only the failed Ansible posthooks that are part of cluster automation templates. Complete the following steps to run only the posthooks again, without retrying the entire upgrade: Add the following content to the root of the ClusterCurator resource to run the install posthook again: operation: retryPosthook: installPosthook Add the following content to the root of the ClusterCurator resource to run the upgrade posthook again: operation: retryPosthook: upgradePosthook After adding the content, a new job is created to run the Ansible posthook. 1.6.11.6. Specifying an Ansible inventory to use for all jobs You can use the ClusterCurator resource to specify an Ansible inventory to use for all jobs. See the following example. Replace channel and desiredUpdate with the correct values for your ClusterCurator : apiVersion: cluster.open-cluster-management.io/v1beta1 kind: ClusterCurator metadata: name: test-inno namespace: test-inno spec: desiredCuration: upgrade destroy: {} install: {} scale: {} upgrade: channel: stable-4.x desiredUpdate: 4.x.1 monitorTimeout: 150 posthook: - extra_vars: {} clusterName: test-inno type: post_check name: ACM Upgrade Checks prehook: - extra_vars: {} clusterName: test-inno type: pre_check name: ACM Upgrade Checks towerAuthSecret: awx inventory: Demo Inventory Note: To use the example resource, the inventory must already exist in Ansible. You can verify that the inventory is created by checking the list of available Ansible inventories from the console. 1.6.11.7. Pushing custom labels from the ClusterCurator resource to the automation job pod You can use the ClusterCurator resource to push custom labels to the automation job pod created by the Cluster Curator. You can push the custom labels on all curation types. See the following example: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: ClusterCurator metadata: name: cluster1 {{{} namespace: cluster1 labels: test1: test1 test2: test2 {}}}spec: desiredCuration: install install: jobMonitorTimeout: 5 posthook: - extra_vars: {} name: Demo Job Template type: Job prehook: - extra_vars: {} name: Demo Job Template type: Job towerAuthSecret: toweraccess 1.6.11.8. Using the ClusterCurator for Extended Update Support (EUS) upgrades You can use the ClusterCurator resource to perform an easier, automatic upgrade between EUS releases. Add spec.upgrade.intermediateUpdate to the ClusterCurator resource with the intermediate release value. See the following sample, where the intermediate release is 4.13.x , and the desiredUpdate is 4.14.x : spec: desiredCuration: upgrade upgrade: intermediateUpdate: 4.13.x desiredUpdate: 4.14.x monitorTimeout: 120 Optional: You can pause the machineconfigpools to skip the intermediate release for faster upgrade. Enter Unpause machinepool in the posthook job, and pause machinepool in the prehook job. See the following example: posthook: - extra_vars: {} name: Unpause machinepool type: Job prehook: - extra_vars: {} name: Pause machinepool type: Job See the following full example of the ClusterCurator that is configured to upgrade EUS to EUS: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: ClusterCurator metadata: annotations: cluster.open-cluster-management.io/upgrade-clusterversion-backoff-limit: "10" name: your-name namespace: your-namespace spec: desiredCuration: upgrade upgrade: intermediateUpdate: 4.13.x desiredUpdate: 4.14.x monitorTimeout: 120 posthook: - extra_vars: {} name: Unpause machinepool type: Job prehook: - extra_vars: {} name: Pause machinepool type: Job 1.6.12. Configuring Ansible Automation Platform jobs to run on hosted clusters Red Hat Ansible Automation Platform is integrated with multicluster engine operator so that you can create prehook and posthook Ansible Automation Platform job instances that occur before or after you create or update hosted clusters.

ClusterClaims A ClusterClaim is a cluster-scoped custom resource definition (CRD) on a managed cluster. A ClusterClaim represents a piece of information that a managed cluster claims. You can use the ClusterClaim to determine the Placement of the resource on the target clusters. The following example shows a ClusterClaim that is identified in the YAML file: apiVersion: cluster.open-cluster-management.io/v1alpha1 kind: ClusterClaim metadata: name: id.openshift.io spec: value: 95f91f25-d7a2-4fc3-9237-2ef633d8451c The following table shows the defined ClusterClaim list for a cluster that multicluster engine operator manages: Claim name Reserved Mutable Description id.k8s.io true false ClusterID defined in upstream proposal kubeversion.open-cluster-management.io true true Kubernetes version platform.open-cluster-management.io true false Platform the managed cluster is running on, such as AWS, GCE, and Equinix Metal product.open-cluster-management.io true false Product name, such as OpenShift, Anthos, EKS and GKE id.openshift.io false false OpenShift Container Platform external ID, which is only available for an OpenShift Container Platform cluster consoleurl.openshift.io false true URL of the management console, which is only available for an OpenShift Container Platform cluster version.openshift.io false true OpenShift Container Platform version, which is only available for an OpenShift Container Platform cluster If any of the claims are deleted or updated on managed cluster, they are restored or rolled back to a version automatically. After the managed cluster joins the hub, any ClusterClaim that is created on a managed cluster is synchronized with the status of the ManagedCluster resource on the hub cluster. See the following example of clusterClaims for a ManagedCluster , replacing 4.x with a supported version of OpenShift Container Platform: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: labels: cloud: Amazon clusterID: 95f91f25-d7a2-4fc3-9237-2ef633d8451c installer.name: multiclusterhub installer.namespace: open-cluster-management name: cluster1 vendor: OpenShift name: cluster1 spec: hubAcceptsClient: true leaseDurationSeconds: 60 status: allocatable: cpu: '15' memory: 65257Mi capacity: cpu: '18' memory: 72001Mi clusterClaims: - name: id.k8s.io value: cluster1 - name: kubeversion.open-cluster-management.io value: v1.18.3+6c42de8 - name: platform.open-cluster-management.io value: AWS - name: product.open-cluster-management.io value: OpenShift - name: id.openshift.io value: 95f91f25-d7a2-4fc3-9237-2ef633d8451c - name: consoleurl.openshift.io value: 'https://console-openshift-console.apps.xxxx.dev04.red-chesterfield.com' - name: version.openshift.io value: '4.x' conditions: - lastTransitionTime: '2020-10-26T07:08:49Z' message: Accepted by hub cluster admin reason: HubClusterAdminAccepted status: 'True' type: HubAcceptedManagedCluster - lastTransitionTime: '2020-10-26T07:09:18Z' message: Managed cluster joined reason: ManagedClusterJoined status: 'True' type: ManagedClusterJoined - lastTransitionTime: '2020-10-30T07:20:20Z' message: Managed cluster is available reason: ManagedClusterAvailable status: 'True' type: ManagedClusterConditionAvailable version: kubernetes: v1.18.3+6c42de8 1.6.13.1. Create custom ClusterClaims You can create a ClusterClaim resource with a custom name on a managed cluster, which makes it easier to identify. The custom ClusterClaim resource is synchronized with the status of the ManagedCluster resource on the hub cluster. The following content shows an example of a definition for a customized ClusterClaim resource: apiVersion: cluster.open-cluster-management.io/v1alpha1 kind: ClusterClaim metadata: name: <custom_claim_name> spec: value: <custom_claim_value> The length of spec.value field must be 1024 or less. The create permission on resource clusterclaims.cluster.open-cluster-management.io is required to create a ClusterClaim resource. 1.6.13.2. List existing ClusterClaims You can use the kubectl command to list the ClusterClaims that apply to your managed cluster so that you can compare your ClusterClaim to an error message. Note: Make sure you have list permission on resource clusterclaims.cluster.open-cluster-management.io . Run the following command to list all existing ClusterClaims that are on the managed cluster: 1.6.14. ManagedClusterSets A ManagedClusterSet is a group of managed clusters. A managed cluster set, can help you manage access to all of your managed clusters. You can also create a ManagedClusterSetBinding resource to bind a ManagedClusterSet resource to a namespace. Each cluster must be a member of a managed cluster set. When you install the hub cluster, a ManagedClusterSet resource is created called default . All clusters that are not assigned to a managed cluster set are automatically assigned to the default managed cluster set. You cannot delete or update the default managed cluster set. Continue reading to learn more about how to create and manage managed cluster sets: Creating a ManagedClusterSet Assigning RBAC permissions to ManagedClusterSets Creating a ManagedClusterSetBinding resource Removing a cluster from a ManagedClusterSet 1.6.14.1. Creating a ManagedClusterSet You can group managed clusters together in a managed cluster set to limit the user access on managed clusters. Required access: Cluster administrator A ManagedClusterSet is a cluster-scoped resource, so you must have cluster administration permissions for the cluster where you are creating the ManagedClusterSet . A managed cluster cannot be included in more than one ManagedClusterSet . You can create a managed cluster set from either the multicluster engine operator console or from the CLI. Note: Cluster pools that are not added to a managed cluster set are not added to the default ManagedClusterSet resource. After a cluster is claimed from the cluster pool, the cluster is added to the default ManagedClusterSet . When you create a managed cluster, the following are automatically created to ease management: A ManagedClusterSet called global . The namespace called open-cluster-management-global-set . A ManagedClusterSetBinding called global to bind the global ManagedClusterSet to the open-cluster-management-global-set namespace. Important: You cannot delete, update, or edit the global managed cluster set. The global managed cluster set includes all managed clusters. See the following example: apiVersion: cluster.open-cluster-management.io/v1beta2 kind: ManagedClusterSetBinding metadata: name: global namespace: open-cluster-management-global-set spec: clusterSet: global 1.6.14.1.1. Creating a ManagedClusterSet by using the CLI Add the following definition of the managed cluster set to your YAML file to create a managed cluster set by using the CLI: apiVersion: cluster.open-cluster-management.io/v1beta2 kind: ManagedClusterSet metadata: name: <cluster_set> Replace <cluster_set> with the name of your managed cluster set. 1.6.14.1.2. Adding a cluster to a ManagedClusterSet After you create your ManagedClusterSet , you can add clusters to your managed cluster set by either following the instructions in the console or by using the CLI. 1.6.14.1.3. Adding clusters to a ManagedClusterSet by using the CLI Complete the following steps to add a cluster to a managed cluster set by using the CLI: Ensure that there is an RBAC ClusterRole entry that allows you to create on a virtual subresource of managedclustersets/join . Note: Without this permission, you cannot assign a managed cluster to a ManagedClusterSet . If this entry does not exist, add it to your YAML file. See the following example: kind: ClusterRole apiVersion: rbac.authorization.k8s.io/v1 metadata: name: clusterrole1 rules: - apiGroups: ["cluster.open-cluster-management.io"] resources: ["managedclustersets/join"] resourceNames: ["<cluster_set>"] verbs: ["create"] Replace <cluster_set> with the name of your ManagedClusterSet . Note: If you are moving a managed cluster from one ManagedClusterSet to another, you must have that permission available on both managed cluster sets. Find the definition of the managed cluster in the YAML file. See the following example definition: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: name: <cluster_name> spec: hubAcceptsClient: true Add the cluster.open-cluster-management.io/clusterset paremeter and specify the name of the ManagedClusterSet . See the following example: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: name: <cluster_name> labels: cluster.open-cluster-management.io/clusterset: <cluster_set> spec: hubAcceptsClient: true 1.6.14.2. Assigning RBAC permissions to a ManagedClusterSet You can assign users or groups to your cluster set that are provided by the configured identity providers on the hub cluster. Required access: Cluster administrator See the following table for the three ManagedClusterSet API RBAC permission levels: Cluster set Access permissions Create permissions admin Full access permission to all of the cluster and cluster pool resources that are assigned to the managed cluster set. Permission to create clusters, import clusters, and create cluster pools. The permissions must be assigned to the managed cluster set when it is created. bind Permission to bind the cluster set to a namespace by creating a ManagedClusterSetBinding . The user or group must also have permission to create the ManagedClusterSetBinding in the target namespace. Read only permissions to all of the cluster and cluster pool resources that are assigned to the managed cluster set. No permission to create clusters, import clusters, or create cluster pools. view Read only permission to all of the cluster and cluster pool resources that are assigned to the managed cluster set. No permission to create clusters, import clusters, or create cluster pools. Note: You cannot apply the Cluster set admin permission for the global cluster set. Complete the following steps to assign users or groups to your managed cluster set from the console: From the OpenShift Container Platform console, navigate to Infrastructure > Clusters . Select the Cluster sets tab. Select your target cluster set. Select the Access management tab. Select Add user or group . Search for, and select the user or group that you want to provide access. Select the Cluster set admin or Cluster set view role to give to the selected user or user group. See Overview of roles in multicluster engine operator Role-based access control for more information. Select Add to submit the changes. Your user or group is displayed in the table. It might take a few seconds for the permission assignments for all of the managed cluster set resources to be propagated to your user or group. See Filtering ManagedClusters from ManagedCusterSets for placement information. 1.6.14.3. Creating a ManagedClusterSetBinding resource A ManagedClusterSetBinding resource binds a ManagedClusterSet resource to a namespace. Applications and policies that are created in the same namespace can only access clusters that are included in the bound managed cluster set resource. Access permissions to the namespace automatically apply to a managed cluster set that is bound to that namespace. If you have access permissions to that namespace, you automatically have permissions to access any managed cluster set that is bound to that namespace. If you only have permissions to access the managed cluster set, you do not automatically have permissions to access other managed cluster sets on the namespace. You can create a managed cluster set binding by using the console or the command line. 1.6.14.3.1. Creating a ManagedClusterSetBinding by using the console Complete the following steps to create a ManagedClusterSetBinding by using the console: From the OpenShift Container Platform console, navigate to Infrastructure > Clusters and select the Cluster sets tab. Select the name of the cluster set that you want to create a binding for. Navigate to Actions > Edit namespace bindings . On the Edit namespace bindings page, select the namespace to which you want to bind the cluster set from the drop-down menu. 1.6.14.3.2. Creating a ManagedClusterSetBinding by using the CLI Complete the following steps to create a ManagedClusterSetBinding by using the CLI: Create the ManagedClusterSetBinding resource in your YAML file. Note: When you create a managed cluster set binding, the name of the managed cluster set binding must match the name of the managed cluster set to bind. Your ManagedClusterSetBinding resource might resemble the following information: apiVersion: cluster.open-cluster-management.io/v1beta2 kind: ManagedClusterSetBinding metadata: namespace: <namespace> name: <cluster_set> spec: clusterSet: <cluster_set> Ensure that you have the bind permission on the target managed cluster set. View the following example of a ClusterRole resource, which contains rules that allow the user to bind to <cluster_set> : apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRole metadata: name: <clusterrole> rules: - apiGroups: ["cluster.open-cluster-management.io"] resources: ["managedclustersets/bind"] resourceNames: ["<cluster_set>"] verbs: ["create"] 1.6.14.4. Placing managed clusters by using taints and tolerations You can control the placement of your managed clusters or managed cluster sets by using taints and tolerations. Taints and tolerations provide a way to prevent managed clusters from being selected for certain placements. This control can be helpful if you want to prevent certain managed clusters from being included in some placements. You can add a taint to the managed cluster, and add a toleration to the placement. If the taint and the toleration do not match, then the managed cluster is not selected for that placement. 1.6.14.4.1. Adding a taint to a managed cluster Taints are specified in the properties of a managed cluster and allow a placement to repel a managed cluster or a set of managed clusters. If the taints section does not exist, you can add a taint to a managed cluster by running a command that resembles the following example: oc patch managedcluster <managed_cluster_name> -p '{"spec":{"taints":[{"key": "key", "value": "value", "effect": "NoSelect"}]}}' --type=merge Alternatively, you can append a taint to existing taints by running a command similar to the following example: oc patch managedcluster <managed_cluster_name> --type='json' -p='[{"op": "add", "path": "/spec/taints/-", "value": {"key": "key", "value": "value", "effect": "NoSelect"}}]' The specification of a taint includes the following fields: Required Key - The taint key that is applied to a cluster. This value must match the value in the toleration for the managed cluster to meet the criteria for being added to that placement. You can determine this value. For example, this value could be bar or foo.example.com/bar . Optional Value - The taint value for the taint key. This value must match the value in the toleration for the managed cluster to meet the criteria for being added to that placement. For example, this value could be value . Required Effect - The effect of the taint on placements that do not tolerate the taint, or what occurs when the taint and the toleration of the placement do not match. The value of the effects must be one of the following values: NoSelect - Placements are not allowed to select a cluster unless they tolerate this taint. If the cluster was selected by the placement before the taint was set, the cluster is removed from the placement decision. NoSelectIfNew - The scheduler cannot select the cluster if it is a new cluster. Placements can only select the cluster if they tolerate the taint and already have the cluster in their cluster decisions. Required TimeAdded - The time when the taint was added. This value is automatically set. 1.6.14.4.2. Identifying built-in taints to reflect the status of managed clusters When a managed cluster is not accessible, you do not want the cluster added to a placement. The following taints are automatically added to managed clusters that are not accessible: cluster.open-cluster-management.io/unavailable - This taint is added to a managed cluster when the cluster has a condition of ManagedClusterConditionAvailable with status of False . The taint has the effect of NoSelect and an empty value to prevent an unavailable cluster from being scheduled. An example of this taint is provided in the following content: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: name: cluster1 spec: hubAcceptsClient: true taints: - effect: NoSelect key: cluster.open-cluster-management.io/unavailable timeAdded: '2022-02-21T08:11:54Z' cluster.open-cluster-management.io/unreachable - This taint is added to a managed cluster when the status of the condition for ManagedClusterConditionAvailable is either Unknown or has no condition. The taint has effect of NoSelect and an empty value to prevent an unreachable cluster from being scheduled. An example of this taint is provided in the following content: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: name: cluster1 spec: hubAcceptsClient: true taints: - effect: NoSelect key: cluster.open-cluster-management.io/unreachable timeAdded: '2022-02-21T08:11:06Z' 1.6.14.4.3. Adding a toleration to a placement Tolerations are applied to placements, and allow the placements to repel managed clusters that do not have taints that match the tolerations of the placement. The specification of a toleration includes the following fields: Optional Key - The key matches the taint key to allow the placement. Optional Value - The value in the toleration must match the value of the taint for the toleration to allow the placement. Optional Operator - The operator represents the relationship between a key and a value. Valid operators are equal and exists . The default value is equal . A toleration matches a taint when the keys are the same, the effects are the same, and the operator is one of the following values: equal - The operator is equal and the values are the same in the taint and the toleration. exists - The wildcard for value, so a placement can tolerate all taints of a particular category. Optional Effect - The taint effect to match. When left empty, it matches all taint effects. The allowed values when specified are NoSelect or NoSelectIfNew . Optional TolerationSeconds - The length of time, in seconds, that the toleration tolerates the taint before moving the managed cluster to a new placement. If the effect value is not NoSelect or PreferNoSelect , this field is ignored. The default value is nil , which indicates that there is no time limit. The starting time of the counting of the TolerationSeconds is automatically listed as the TimeAdded value in the taint, rather than in the value of the cluster scheduled time or the TolerationSeconds added time. The following example shows how to configure a toleration that tolerates clusters that have taints: Taint on the managed cluster for this example: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: name: cluster1 spec: hubAcceptsClient: true taints: - effect: NoSelect key: gpu value: "true" timeAdded: '2022-02-21T08:11:06Z' Toleration on the placement that allows the taint to be tolerated apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement1 namespace: default spec: tolerations: - key: gpu value: "true" operator: Equal With the example tolerations defined, cluster1 could be selected by the placement because the key: gpu and value: "true" match. Note: A managed cluster is not guaranteed to be placed on a placement that contains a toleration for the taint. If other placements contain the same toleration, the managed cluster might be placed on one of those placements. 1.6.14.4.4. Specifying a temporary toleration The value of TolerationSeconds specifies the period of time that the toleration tolerates the taint. This temporary toleration can be helpful when a managed cluster is offline and you can transfer applications that are deployed on this cluster to another managed cluster for a tolerated time. For example, the managed cluster with the following taint becomes unreachable: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: name: cluster1 spec: hubAcceptsClient: true taints: - effect: NoSelect key: cluster.open-cluster-management.io/unreachable timeAdded: '2022-02-21T08:11:06Z' If you define a placement with a value for TolerationSeconds , as in the following example, the workload transfers to another available managed cluster after 5 minutes. apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: demo4 namespace: demo1 spec: tolerations: - key: cluster.open-cluster-management.io/unreachable operator: Exists tolerationSeconds: 300 The application is moved to another managed cluster after the managed cluster is unreachable for 5 minutes. 1.6.14.4.5. Additional resources To learn more about taints and tolerations, see Using taints and tolerations to control logging pod placement in the OpenShift Container Platform documentation. To learn how to use oc patch , see oc patch the OpenShift Container Platform documentation 1.6.14.5. Removing a managed cluster from a ManagedClusterSet You might want to remove a managed cluster from a managed cluster set to move it to a different managed cluster set, or remove it from the management settings of the set. You can remove a managed cluster from a managed cluster set by using the console or the CLI. Notes: Every managed cluster must be assigned to a managed cluster set. If you remove a managed cluster from a ManagedClusterSet and do not assign it to a different ManagedClusterSet , the cluster is automatically added to the default managed cluster set. If the Submariner add-on is installed on your managed cluster, you must uninstall the add-on before removing your managed cluster from a ManagedClusterSet . 1.6.14.5.1. Removing a cluster from a ManagedClusterSet by using the console Complete the following steps to remove a cluster from a managed cluster set by using the console: Click Infrastructure > Clusters and ensure that the Cluster sets tab is selected. Select the name of the cluster set that you want to remove from the managed cluster set to view the cluster set details. Select Actions > Manage resource assignments . On the Manage resource assignments page, remove the checkbox for the resources that you want to remove from the cluster set. This step removes a resource that is already a member of the cluster set. You can see if the resource is already a member of a cluster set by viewing the details of the managed cluster. Note: If you are moving a managed cluster from one managed cluster set to another, you must have the required RBAC permissions on both managed cluster sets. 1.6.14.5.2. Removing a cluster from a ManagedClusterSet by using the CLI To remove a cluster from a managed cluster set by using the command line, complete the following steps: Run the following command to display a list of managed clusters in the managed cluster set: Replace cluster_set with the name of the managed cluster set. Locate the entry for the cluster that you want to remove. Remove the label from the YAML entry for the cluster that you want to remove. See the following code for an example of the label: labels: cluster.open-cluster-management.io/clusterset: clusterset1 Note: If you are moving a managed cluster from one cluster set to another, you must have the required RBAC permission on both managed cluster sets. 1.6.15. Placement A placement resource is a namespace-scoped resource that defines a rule to select a set of ManagedClusters from the ManagedClusterSets , which are bound to the placement namespace. Required access: Cluster administrator, Cluster set administrator Continue reading to learn more about how to use placements: Placement overview Filtering ManagedClusters from ManagedCusterSets Checking selected ManagedClusters by using PlacementDecisions 1.6.15.1. Placement overview See the following information about how placement with managed clusters works: Kubernetes clusters are registered with the hub cluster as cluster-scoped ManagedClusters . The ManagedClusters are organized into cluster-scoped ManagedClusterSets . The ManagedClusterSets are bound to workload namespaces. The namespace-scoped placements specify a portion of ManagedClusterSets that select a working set of the potential ManagedClusters . Placements filter ManagedClusters from ManagedClusterSets by using labelSelector and claimSelector . The placement of ManagedClusters can be controlled by using taints and tolerations. Placements rank the clusters by the requirements and select a subset of clusters from them. Placements do not select managed clusters that you are deleting. Notes: You must bind at least one ManagedClusterSet to a namespace by creating a ManagedClusterSetBinding in that namespace. You must have role-based access to CREATE on the virtual sub-resource of managedclustersets/bind . 1.6.15.1.1. Additional resources See Using taints and tolerations to place managed clusters for more information. See Placements API to learn more about the API. Return to Selecting ManagedClusters with placement . 1.6.15.2. Filtering ManagedClusters from ManagedClusterSets You can select which ManagedClusters to filter by using labelSelector or claimSelector . See the following examples to learn how to use both filters: In the following example, the labelSelector only matches clusters with the label vendor: OpenShift : apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement namespace: ns1 spec: predicates: - requiredClusterSelector: labelSelector: matchLabels: vendor: OpenShift In the following example, claimSelector only matches clusters with region.open-cluster-management.io with us-west-1 : apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement namespace: ns1 spec: predicates: - requiredClusterSelector: claimSelector: matchExpressions: - key: region.open-cluster-management.io operator: In values: - us-west-1 You can also filter ManagedClusters from particular cluster sets by using the clusterSets parameter. In the following example, claimSelector only matches the cluster sets clusterset1 and clusterset2 : apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement namespace: ns1 spec: clusterSets: - clusterset1 - clusterset2 predicates: - requiredClusterSelector: claimSelector: matchExpressions: - key: region.open-cluster-management.io operator: In values: - us-west-1 You can also choose how many ManagedClusters you want to filter by using the numberOfClusters paremeter. See the following example: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement namespace: ns1 spec: numberOfClusters: 3 1 predicates: - requiredClusterSelector: labelSelector: matchLabels: vendor: OpenShift claimSelector: matchExpressions: - key: region.open-cluster-management.io operator: In values: - us-west-1 1 Specify how many ManagedClusters you want to select. The example is set to 3 . 1.6.15.2.1. Filtering ManagedClusters by defining tolerations with placement To learn how to filter ManagedClusters with matching taints, see the following examples: By default, the placement cannot select cluster1 in the following example: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: name: cluster1 spec: hubAcceptsClient: true taints: - effect: NoSelect key: gpu value: "true" timeAdded: '2022-02-21T08:11:06Z' To select cluster1 you must define tolerations. See the following example: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement namespace: ns1 spec: tolerations: - key: gpu value: "true" operator: Equal You can also select ManagedClusters with matching taints for a specified amount of time by using the tolerationSeconds parameter. tolerationSeconds defines how long a toleration stays bound to a taint. tolerationSeconds can automatically transfer applications that are deployed on a cluster that goes offline to another managed cluster after a specified length of time. Learn how to use tolerationSeconds by viewing the following examples: In the following example, the managed cluster becomes unreachable: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: name: cluster1 spec: hubAcceptsClient: true taints: - effect: NoSelect key: cluster.open-cluster-management.io/unreachable timeAdded: '2022-02-21T08:11:06Z' If you define a placement with tolerationSeconds , the workload is transferred to another available managed cluster. See the following example: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement namespace: ns1 spec: tolerations: - key: cluster.open-cluster-management.io/unreachable operator: Exists tolerationSeconds: 300 1 1 Specify after how many seconds you want the workload to be transferred. 1.6.15.2.2. Prioritizing ManagedClusters by defining prioritizerPolicy with placement View the following examples to learn how to prioritize ManagedClusters by using the prioritizerPolicy parameter with placement. The following example selects a cluster with the largest allocatable memory: Note: Similar to Kubernetes Node Allocatable , 'allocatable' is defined as the amount of compute resources that are available for pods on each cluster. apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement namespace: ns1 spec: numberOfClusters: 1 prioritizerPolicy: configurations: - scoreCoordinate: builtIn: ResourceAllocatableMemory The following example selects a cluster with the largest allocatable CPU and memory, and makes placement sensitive to resource changes: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement namespace: ns1 spec: numberOfClusters: 1 prioritizerPolicy: configurations: - scoreCoordinate: builtIn: ResourceAllocatableCPU weight: 2 - scoreCoordinate: builtIn: ResourceAllocatableMemory weight: 2 The following example selects two clusters with the largest addOn score CPU ratio, and pins the placement decisions: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement namespace: ns1 spec: numberOfClusters: 2 prioritizerPolicy: mode: Exact configurations: - scoreCoordinate: builtIn: Steady weight: 3 - scoreCoordinate: type: AddOn addOn: resourceName: default scoreName: cpuratio 1.6.15.2.3. Filtering ManagedClusters based on add-on status You might want to select managed clusters for your placements based on the status of the add-ons that are deployed on them. For example, you can select a managed cluster for your placement only if there is a specific add-on that is enabled on the managed cluster. You can specify the label for the add-on, as well as its status, when you create the placement. A label is automatically created on a ManagedCluster resource if an add-on is enabled on the managed cluster. The label is automatically removed if the add-on is disabled. Each add-on is represented by a label in the format of feature.open-cluster-management.io/addon-<addon_name>=<status_of_addon> . Replace addon_name with the name of the add-on that you want to enable on the selected managed cluster. Replace status_of_addon with the status that you want the add-on to have if the managed cluster is selected. See the following table of possible value for status_of_addon : Value Description available The add-on is enabled and available. unhealthy The add-on is enabled, but the lease is not updated continuously. unreachable The add-on is enabled, but there is no lease found for it. This can also be caused when the managed cluster is offline. For example, an available application-manager add-on is represented by a label on the managed cluster that reads the following: See the following examples to learn how to create placements based on add-ons and their status: The following placement example includes all managed clusters that have application-manager enabled on them: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement1 namespace: ns1 spec: predicates: - requiredClusterSelector: labelSelector: matchExpressions: - key: feature.open-cluster-management.io/addon-application-manager operator: Exists The following placement example includes all managed clusters that have application-manager enabled with an available status: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement2 namespace: ns1 spec: predicates: - requiredClusterSelector: labelSelector: matchLabels: "feature.open-cluster-management.io/addon-application-manager": "available" The following placement example includes all managed clusters that have application-manager disabled: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: Placement metadata: name: placement3 namespace: ns1 spec: predicates: - requiredClusterSelector: labelSelector: matchExpressions: - key: feature.open-cluster-management.io/addon-application-manager operator: DoesNotExist 1.6.15.2.4. Additional resources See Node Allocatable for more details. Return to Selecting ManagedClusters with placement for other topics. 1.6.15.3. Checking selected ManagedClusters by using PlacementDecisions One or more PlacementDecision kinds with the label cluster.open-cluster-management.io/placement={placement_name} are created to represent ManagedClusters selected by a placement. If a ManagedCluster is selected and added to a PlacementDecision , components that consume this placement might apply the workload on this ManagedCluster . After the ManagedCluster is no longer selected and is removed from the PlacementDecision , the workload that is applied on this ManagedCluster is removed. See PlacementDecisions API to learn more about the API. See the following PlacementDecision example: apiVersion: cluster.open-cluster-management.io/v1beta1 kind: PlacementDecision metadata: labels: cluster.open-cluster-management.io/placement: placement1 name: placement1-kbc7q namespace: ns1 ownerReferences: - apiVersion: cluster.open-cluster-management.io/v1beta1 blockOwnerDeletion: true controller: true kind: Placement name: placement1 uid: 05441cf6-2543-4ecc-8389-1079b42fe63e status: decisions: - clusterName: cluster1 reason: '' - clusterName: cluster2 reason: '' - clusterName: cluster3 reason: '' 1.6.15.3.1.

Managing cluster pools (Technology Preview) Cluster pools provide rapid and cost-effective access to configured Red Hat OpenShift Container Platform clusters on-demand and at scale. Cluster pools provision a configurable and scalable number of OpenShift Container Platform clusters on Amazon Web Services, Google Cloud Platform, or Microsoft Azure that can be claimed when they are needed. They are especially useful when providing or replacing cluster environments for development, continuous integration, and production scenarios. You can specify a number of clusters to keep running so that they are available to be claimed immediately, while the remainder of the clusters will be kept in a hibernating state so that they can be resumed and claimed within a few minutes. ClusterClaim resources are used to check out clusters from cluster pools. When a cluster claim is created, the pool assigns a running cluster to it. If no running clusters are available, a hibernating cluster is resumed to provide the cluster or a new cluster is provisioned. The cluster pool automatically creates new clusters and resumes hibernating clusters to maintain the specified size and number of available running clusters in the pool. Creating a cluster pool Claiming clusters from cluster pools Updating the cluster pool release image Scaling cluster pools Destroying a cluster pool The procedure for creating a cluster pool is similar to the procedure for creating a cluster. Clusters in a cluster pool are not created for immediate use. 1.6.16.1. Creating a cluster pool The procedure for creating a cluster pool is similar to the procedure for creating a cluster. Clusters in a cluster pool are not created for immediate use. Required access : Administrator 1.6.16.1.1. Prerequisites See the following prerequisites before creating a cluster pool: You need to deploy a multicluster engine operator hub cluster. You need Internet access for your multicluster engine operator hub cluster so that it can create the Kubernetes cluster on the provider environment. You need an AWS, GCP, or Microsoft Azure provider credential. See Managing credentials overview for more information. You need a configured domain in your provider environment. See your provider documentation for instructions about how to configure a domain. You need provider login credentials. You need your OpenShift Container Platform image pull secret. See Using image pull secrets . Note: Adding a cluster pool with this procedure configures it so it automatically imports the cluster for multicluster engine operator management when you claim a cluster from the pool. If you want to create a cluster pool that does not automatically import the claimed cluster for management with the cluster claim, add the following annotation to your clusterClaim resource: kind: ClusterClaim metadata: annotations: cluster.open-cluster-management.io/createmanagedcluster: "false" 1 1 The word "false" must be surrounded by quotation marks to indicate that it is a string. 1.6.16.1.2. Create the cluster pool To create a cluster pool, select Infrastructure > Clusters in the navigation menu. The Cluster pools tab lists the cluster pools that you can access. Select Create cluster pool and complete the steps in the console. If you do not have a infrastructure credential that you want to use for the cluster pool, you can create one by selecting Add credential . You can either select an existing namespace from the list, or type the name of a new one to create one. The cluster pool does not have to be in the same namespace as the clusters. You can select a cluster set name if you want the RBAC roles for your cluster pool to share the role assignments of an existing cluster set. The cluster set for the clusters in the cluster pool can only be set when you create the cluster pool. You cannot change the cluster set association for the cluster pool or for the clusters in the cluster pool after you create the cluster pool. Any cluster that you claim from the cluster pool is automatically added to the same cluster set as the cluster pool. Note: If you do not have cluster admin permissions, you must select a cluster set. The request to create a cluster set is rejected with a forbidden error if you do not include the cluster set name in this situation. If no cluster sets are available for you to select, contact your cluster administrator to create a cluster set and give you clusterset admin permissions to it. The cluster pool size specifies the number of clusters that you want provisioned in your cluster pool, while the cluster pool running count specifies the number of clusters that the pool keeps running and ready to claim for immediate use. The procedure is very similar to the procedure for creating clusters. For specific information about the information that is required for your provider, see the following information: Creating a cluster on Amazon Web Services Creating a cluster on Google Cloud Platform Creating a cluster on Microsoft Azure 1.6.16.2. Claiming clusters from cluster pools ClusterClaim resources are used to check out clusters from cluster pools. A claim is completed when a cluster is running and ready in the cluster pool. The cluster pool automatically creates new running and hibernated clusters in the cluster pool to maintain the requirements that are specified for the cluster pool. Note: When a cluster that was claimed from the cluster pool is no longer needed and is destroyed, the resources are deleted. The cluster does not return to the cluster pool. Required access : Administrator 1.6.16.2.1. Prerequisite You must have the following available before claiming a cluster from a cluster pool: A cluster pool with or without available clusters. If there are available clusters in the cluster pool, the available clusters are claimed. If there are no available clusters in the cluster pool, a cluster is created to fulfill the claim. See Creating a cluster pool for information about how to create a cluster pool. 1.6.16.2.2. Claim the cluster from the cluster pool When you create a cluster claim, you request a new cluster from the cluster pool. A cluster is checked out from the pool when a cluster is available. The claimed cluster is automatically imported as one of your managed clusters, unless you disabled automatic import. Complete the following steps to claim a cluster: From the navigation menu, click Infrastructure > Clusters , and select the Cluster pools tab. Find the name of the cluster pool you want to claim a cluster from and select Claim cluster . If a cluster is available, it is claimed and immediately appears in the Managed clusters tab. If there are no available clusters, it might take several minutes to resume a hibernated cluster or provision a new cluster. During this time, the claim status is pending . Expand the cluster pool to view or delete pending claims against it. The claimed cluster remains a member of the cluster set that it was associated with when it was in the cluster pool. You cannot change the cluster set of the claimed cluster when you claim it. Note: Changes to the pull secret, SSH keys, or base domain of the cloud provider credentials are not reflected for existing clusters that are claimed from a cluster pool, as they have already been provisioned using the original credentials. You cannot edit cluster pool information by using the console, but you can update it by updating its information using the CLI interface. You can also create a new cluster pool with a credential that contains the updated information. The clusters that are created in the new pool use the settings provided in the new credential. 1.6.16.3. Updating the cluster pool release image When the clusters in your cluster pool remain in hibernation for some time, the Red Hat OpenShift Container Platform release image of the clusters might become backlevel. If this happens, you can upgrade the version of the release image of the clusters that are in your cluster pool. Required access : Edit Complete the following steps to update the OpenShift Container Platform release image for the clusters in your cluster pool: Note: This procedure does not update clusters from the cluster pool that are already claimed in the cluster pool. After you complete this procedure, the updates to the release images only apply to the following clusters that are related to the cluster pool: Clusters that are created by the cluster pool after updating the release image with this procedure. Clusters that are hibernating in the cluster pool. The existing hibernating clusters with the old release image are destroyed, and new clusters with the new release image replace them. From the navigation menu, click Infrastructure > Clusters . Select the Cluster pools tab. Find the name of the cluster pool that you want to update in the Cluster pools table. Click the Options menu for the Cluster pools in the table, and select Update release image . Select a new release image to use for future cluster creations from this cluster pool. The cluster pool release image is updated. Tip: You can update the release image for multiple cluster pools with one action by selecting the box for each of the cluster pools and using the Actions menu to update the release image for the selected cluster pools. 1.6.16.4. Scaling cluster pools (Technology Preview) You can change the number of clusters in the cluster pool by increasing or decreasing the number of clusters in the cluster pool size. Required access : Cluster administrator Complete the following steps to change the number of clusters in your cluster pool: From the navigation menu, click Infrastructure > Clusters . Select the Cluster pools tab. In the Options menu for the cluster pool that you want to change, select Scale cluster pool . Change the value of the pool size. Optionally, you can update the number of running clusters to increase or decrease the number of clusters that are immediately available when you claim them. Your cluster pools are scaled to reflect your new values. 1.6.16.5. Destroying a cluster pool If you created a cluster pool and determine that you no longer need it, you can destroy the cluster pool. Important: You can only destroy cluster pools that do not have any cluster claims. Required access : Cluster administrator To destroy a cluster pool, complete the following steps: From the navigation menu, click Infrastructure > Clusters . Select the Cluster pools tab. In the Options menu for the cluster pool that you want to delete, type confirm in the confirmation box and select Destroy . Notes: The Destroy button is disabled if the cluster pool has any cluster claims. The namespace that contains the cluster pool is not deleted. Deleting the namespace destroys any clusters that have been claimed from the cluster pool, since the cluster claim resources for these clusters are created in the same namespace. Tip: You can destroy multiple cluster pools with one action by selecting the box for each of the cluster pools and using the Actions menu to destroy the selected cluster pools. 1.6.17. Enabling ManagedServiceAccount add-ons When you install a supported version of multicluster engine operator, the ManagedServiceAccount add-on is enabled by default. Important: If you upgraded your hub cluster from multicluster engine operator version 2.4 and did not enable the ManagedServiceAccount add-on before upgrading, you must enable the add-on manually. The ManagedServiceAccount allows you to create or delete a service account on a managed cluster. Required access: Editor When a ManagedServiceAccount custom resource is created in the <managed_cluster> namespace on the hub cluster, a ServiceAccount is created on the managed cluster. A TokenRequest is made with the ServiceAccount on the managed cluster to the Kubernetes API server on the managed cluster. The token is then stored in a Secret in the <target_managed_cluster> namespace on the hub cluster. Note: The token can expire and be rotated. See TokenRequest for more information about token requests. 1.6.17.1. Prerequisites You need a supported Red Hat OpenShift Container Platform environment. You need the multicluster engine operator installed. 1.6.17.2. Enabling ManagedServiceAccount To enable a ManagedServiceAccount add-on for a hub cluster and a managed cluster, complete the following steps: Enable the ManagedServiceAccount add-on on hub cluster. See Advanced configuration to learn more. Deploy the ManagedServiceAccount add-on and apply it to your target managed cluster. Create the following YAML file and replace target_managed_cluster with the name of the managed cluster where you are applying the Managed-ServiceAccount add-on: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: ManagedClusterAddOn metadata: name: managed-serviceaccount namespace: <target_managed_cluster> spec: installNamespace: open-cluster-management-agent-addon Run the following command to apply the file: You have now enabled the ManagedServiceAccount plug-in for your managed cluster. See the following steps to configure a ManagedServiceAccount . Create a ManagedServiceAccount custom resource with the following YAML source: apiVersion: authentication.open-cluster-management.io/v1alpha1 kind: ManagedServiceAccount metadata: name: <managedserviceaccount_name> namespace: <target_managed_cluster> spec: rotation: {} Replace managed_serviceaccount_name with the name of your ManagedServiceAccount . Replace target_managed_cluster with the name of the managed cluster to which you are applying the ManagedServiceAccount . To verify, view the tokenSecretRef attribute in the ManagedServiceAccount object status to find the secret name and namespace. Run the following command with your account and cluster name: View the Secret containing the retrieved token that is connected to the created ServiceAccount on the managed cluster. Run the following command: 1.6.18. Cluster lifecycle advanced configuration You can configure some cluster settings during or after installation. 1.6.18.1. Customizing API server certificates The managed clusters communicate with the hub cluster through a mutual connection with the OpenShift Kube API server external load balancer. The default OpenShift Kube API server certificate is issued by an internal Red Hat OpenShift Container Platform cluster certificate authority (CA) when OpenShift Container Platform is installed. If necessary, you can add or change certificates. Changing the API server certificate might impact the communication between the managed cluster and the hub cluster. When you add the named certificate before installing the product, you can avoid an issue that might leave your managed clusters in an offline state. The following list contains some examples of when you might need to update your certificates: You want to replace the default API server certificate for the external load balancer with your own certificate. By following the guidance in Adding API server certificates in the OpenShift Container Platform documentation, you can add a named certificate with host name api.<cluster_name>.<base_domain> to replace the default API server certificate for the external load balancer. Replacing the certificate might cause some of your managed clusters to move to an offline state. If your clusters are in an offline state after upgrading the certificates, follow the troubleshooting instructions for Troubleshooting imported clusters offline after certificate change to resolve it. Note: Adding the named certificate before installing the product helps to avoid your clusters moving to an offline state. The named certificate for the external load balancer is expiring and you need to replace it. If both the old and the new certificate share the same root CA certificate, despite the number of intermediate certificates, you can follow the guidance in Adding API server certificates in the OpenShift Container Platform documentation to create a new secret for the new certificate. Then update the serving certificate reference for host name api.<cluster_name>.<base_domain> to the new secret in the APIServer custom resource. Otherwise, when the old and new certificates have different root CA certificates, complete the following steps to replace the certificate: Locate your APIServer custom resource, which resembles the following example: apiVersion: config.openshift.io/v1 kind: APIServer metadata: name: cluster spec: audit: profile: Default servingCerts: namedCertificates: - names: - api.mycluster.example.com servingCertificate: name: old-cert-secret Create a new secret in the openshift-config namespace that contains the content of the existing and new certificates by running the following commands: Copy the old certificate into a new certificate: cp old.crt combined.crt Add the contents of the new certificate to the copy of the old certificate: cat new.crt >> combined.crt Apply the combined certificates to create a secret: oc create secret tls combined-certs-secret --cert=combined.crt --key=old.key -n openshift-config Update your APIServer resource to reference the combined certificate as the servingCertificate . apiVersion: config.openshift.io/v1 kind: APIServer metadata: name: cluster spec: audit: profile: Default servingCerts: namedCertificates: - names: - api.mycluster.example.com servingCertificate: name: combined-cert-secret After about 15 minutes, the CA bundle containing both new and old certificates is propagated to the managed clusters. Create another secret named new-cert-secret in the openshift-config namespace that contains only the new certificate information by entering the following command: oc create secret tls new-cert-secret --cert=new.crt --key=new.key -n openshift-config {code} Update the APIServer resource by changing the name of servingCertificate to reference the new-cert-secret . Your resource might resemble the following example: apiVersion: config.openshift.io/v1 kind: APIServer metadata: name: cluster spec: audit: profile: Default servingCerts: namedCertificates: - names: - api.mycluster.example.com servingCertificate: name: new-cert-secret After about 15 minutes, the old certificate is removed from the CA bundle, and the change is automatically propagated to the managed clusters. Note: Managed clusters must use the host name api.<cluster_name>.<base_domain> to access the hub cluster. You cannot use named certificates that are configured with other host names. 1.6.18.2. Configuring the proxy between hub cluster and managed cluster To register a managed cluster to your multicluster engine for Kubernetes operator hub cluster, you need to transport the managed cluster to your multicluster engine operator hub cluster. Sometimes your managed cluster cannot directly reach your multicluster engine operator hub cluster. In this instance, configure the proxy settings to allow the communications from the managed cluster to access the multicluster engine operator hub cluster through a HTTP or HTTPS proxy server. For example, the multicluster engine operator hub cluster is in a public cloud, and the managed cluster is in a private cloud environment behind firewalls. The communications out of the private cloud can only go through a HTTP or HTTPS proxy server. 1.6.18.2.1. Prerequisites You have a HTTP or HTTPS proxy server running that supports HTTP tunnels. For example, HTTP connect method. You have a manged cluster that can reach the HTTP or HTTPS proxy server, and the proxy server can access the multicluster engine operator hub cluster. Complete the following steps to configure the proxy settings between hub cluster and managed cluster: Create a KlusterConfig resource with proxy settings. See the following configuration with HTTP proxy: apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: http-proxy spec: hubKubeAPIServerProxyConfig: httpProxy: "http://<username>:<password>@<ip>:<port>" See the following configuration with HTTPS proxy: apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: https-proxy spec: hubKubeAPIServerProxyConfig: httpsProxy: "https://<username>:<password>@<ip>:<port>" caBundle: <user-ca-bundle> Note: A CA certificate is required when the HTTPS proxy server is configured. The HTTPS proxy is used if both HTTP proxy and HTTPS proxy are specified. When creating a managed cluster, choose the KlusterletConfig resource by adding an annotation that refers to the KlusterletConfig resource. See the following example: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: annotations: agent.open-cluster-management.io/klusterlet-config: <klusterlet-config-name> name:<managed-cluster-name> spec: hubAcceptsClient: true leaseDurationSeconds: 60 Notes: You might need to toggle the YAML view to add the annotation to the ManagedCluster resource when you operate on the multicluster engine operator console. You can use a global KlusterletConfig to enable the configuration on every managed cluster without using an annotation for binding. 1.6.18.2.2. Disabling the proxy between hub cluster and managed cluster If your development changes, you might need to disable the HTTP or HTTPS proxy. Go to ManagedCluster resource. Remove the annotation, agent.open-cluster-management.io/klusterlet-config . 1.6.18.2.3. Optional: Configuring the klusterlet to run on specific nodes When you create a cluster using Red Hat Advanced Cluster Management for Kubernetes, you can specify which nodes you want to run the managed cluster klusterlet to run on by configuring the nodeSelector and tolerations annotation for the managed cluster. Complete the following steps to configure these settings: Select the managed cluster that you want to update from the clusters page in the console. Set the YAML switch to On to view the YAML content. Note: The YAML editor is only available when importing or creating a cluster. To edit the managed cluster YAML definition after importing or creating, you must use the OpenShift Container Platform command-line interface or the Red Hat Advanced Cluster Management search feature. Add the nodeSelector annotation to the managed cluster YAML definition. The key for this annotation is: open-cluster-management/nodeSelector . The value of this annotation is a string map with JSON formatting. Add the tolerations entry to the managed cluster YAML definition. The key of this annotation is: open-cluster-management/tolerations . The value of this annotation represents a toleration list with JSON formatting. The resulting YAML might resemble the following example: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: annotations: open-cluster-management/nodeSelector: '{"dedicated":"acm"}' open-cluster-management/tolerations: '[{"key":"dedicated","operator":"Equal","value":"acm","effect":"NoSchedule"}]' 1.6.18.3. Customizing the server URL and CA bundle of the hub cluster API server when importing a managed cluster (Technology Preview) You might not be able to register a managed cluster on your multicluster engine operator hub cluster if intermediate components exist between the managed cluster and the hub cluster. Example intermediate components include a Virtual IP, load balancer, reverse proxy, or API gateway. If you have an intermediate component, you must use a custom server URL and CA bundle for the hub cluster API server when importing a managed cluster. 1.6.18.3.1. Prerequisites You must configure the intermediate component so that the hub cluster API server is accessible for the managed cluster. If the intermediate component terminates the SSL connections between the managed cluster and hub cluster API server, you must bridge the SSL connections and pass the authentication information from the original requests to the back end of the hub cluster API server. You can use the User Impersonation feature of the Kubernetes API server to bridge the SSL connections. The intermediate component extracts the client certificate from the original requests, adds Common Name (CN) and Organization (O) of the certificate subject as impersonation headers, and then forwards the modified impersonation requests to the back end of the hub cluster API server. Note: If you bridge the SSL connections, the cluster proxy add-on does not work. 1.6.18.3.2. Customizing the server URL and hub cluster CA bundle To use a custom hub API server URL and CA bundle when importing a managed cluster, complete the following steps: Create a KlusterConfig resource with the custom hub cluster API server URL and CA bundle. See the following example: apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: 1 spec: hubKubeAPIServerURL: "https://api.example.com:6443" 2 hubKubeAPIServerCABundle: "LS0tLS1CRU...LS0tCg==" 3 1 Add your klusterlet config name. 2 Add your custom server URL. 3 Add your custom CA bundle. Select the KlusterletConfig resource when creating a managed cluster by adding an annotation that refers to the resource. See the following example: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: annotations: agent.open-cluster-management.io/klusterlet-config: 1 name: 2 spec: hubAcceptsClient: true leaseDurationSeconds: 60 1 Add your klusterlet config name. 2 Add your cluster name. Notes: If you use the console, you might need to enable the YAML view to add the annotation to the ManagedCluster resource. You can use a global KlusterletConfig to enable the configuration on every managed cluster without using an annotation for binding. 1.6.18.3.3. Configuring the global KlusterletConfig If you create a KlusterletConfig resource and set the name to global , the configurations in the global KlusterletConfig are automatically applied on every managed cluster. If you create another KlusterletConfig in an environment that has a global KlusterletConfig and bind it with a managed cluster, the value of your KlusterletConfig overrides the global KlusterletConfig value if you set different values for the same field. See the following example where the hubKubeAPIServerURL field has different values set in your KlusterletConfig and the global KlusterletConfig . The "example.test.com" value overrides the "example.global.com" value: apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: test spec: hubKubeAPIServerURL: "example.test.com" - apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: global spec: hubKubeAPIServerURL: "example.global.com" If you create another KlusterletConfig in an environment that has a global KlusterletConfig and bind it with a managed cluster, the value of the global KlusterletConfig is used if the same field is missing or does not have a value in your KlusterletConfig . See the following examples, where the "example.global.com" value in the hubKubeAPIServerURL field of the global KlusterletConfig overrides your KlusterletConfig . apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: test spec: hubKubeAPIServerURL: "" - apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: global spec: hubKubeAPIServerURL: "example.global.com" apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: test - apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: global spec: hubKubeAPIServerURL: "example.global.com" 1.6.18.4.

Removing a cluster from management When you remove an OpenShift Container Platform cluster from management that was created with multicluster engine operator, you can either detach it or destroy it. Detaching a cluster removes it from management, but does not completely delete it. You can import it again if you want to manage it. This is only an option when the cluster is in a Ready state. The following procedures remove a cluster from management in either of the following situations: You already deleted the cluster and want to remove the deleted cluster from Red Hat Advanced Cluster Management. You want to remove the cluster from management, but have not deleted the cluster. Important: Destroying a cluster removes it from management and deletes the components of the cluster. When you detach or destroy a managed cluster, the related namespace is automatically deleted. Do not place custom resources in this namespace. Removing a cluster by using the console Removing a cluster by using the command line Removing remaining resources after removing a cluster Defragmenting the etcd database after removing a cluster 1.6.19.1. Removing a cluster by using the console From the navigation menu, navigate to Infrastructure > Clusters and select Destroy cluster or Detach cluster from the options menu beside the cluster that you want to remove from management. Tip: You can detach or destroy multiple clusters by selecting the check boxes of the clusters that you want to detach or destroy and selecting Detach or Destroy . Note: If you attempt to detach the hub cluster while it is managed, which is called a local-cluster , check to see if the default setting of disableHubSelfManagement is false . This setting causes the hub cluster to reimport itself and manage itself when it is detached, and it reconciles the MultiClusterHub controller. It might take hours for the hub cluster to complete the detachment process and reimport. To reimport the hub cluster without waiting for the processes to finish, you can enter the following command to restart the multiclusterhub-operator pod and reimport faster: You can change the value of the hub cluster to not import automatically by changing the disableHubSelfManagement value to true , as described in Installing while connected online . 1.6.19.2. Removing a cluster by using the command line To detach a managed cluster by using the command line of the hub cluster, run the following command: To destroy the managed cluster after detaching, run the following command: Notes: To prevent destroying the managed cluster, set the spec.preserveOnDelete parameter to true in the ClusterDeployment custom resource. The default setting of disableHubSelfManagement is false . The false`setting causes the hub cluster, also called `local-cluster , to reimport and manage itself when it is detached and it reconciles the MultiClusterHub controller. The detachment and reimport process might take hours might take hours for the hub cluster to complete. If you want to reimport the hub cluster without waiting for the processes to finish, you can enter the following command to restart the multiclusterhub-operator pod and reimport faster: You can change the value of the hub cluster to not import automatically by changing the disableHubSelfManagement value to true . See Installing while connected online . 1.6.19.3. Removing remaining resources after removing a cluster If there are remaining resources on the managed cluster that you removed, there are additional steps that are required to ensure that you remove all of the remaining components. Situations when these extra steps are required include the following examples: The managed cluster was detached before it was completely created, and components like the klusterlet remain on the managed cluster. The hub that was managing the cluster was lost or destroyed before detaching the managed cluster, and there is no way to detach the managed cluster from the hub. The managed cluster was not in an online state when it was detached. If one of these situations apply to your attempted detachment of a managed cluster, there are some resources that cannot be removed from managed cluster. Complete the following steps to detach the managed cluster: Make sure you have the oc command line interface configured. Make sure you have KUBECONFIG configured on your managed cluster. If you run oc get ns | grep open-cluster-management-agent , you should see two namespaces: Remove the klusterlet custom resource by using the following command: oc get klusterlet | grep klusterlet | awk '{print USD1}' | xargs oc patch klusterlet --type=merge -p '{"metadata":{"finalizers": []}}' Run the following command to remove the remaining resources: oc delete namespaces open-cluster-management-agent open-cluster-management-agent-addon --wait=false oc get crds | grep open-cluster-management.io | awk '{print USD1}' | xargs oc delete crds --wait=false oc get crds | grep open-cluster-management.io | awk '{print USD1}' | xargs oc patch crds --type=merge -p '{"metadata":{"finalizers": []}}' Run the following command to ensure that both namespaces and all open cluster management crds are removed: oc get crds | grep open-cluster-management.io | awk '{print USD1}' oc get ns | grep open-cluster-management-agent 1.6.19.4. Defragmenting the etcd database after removing a cluster Having many managed clusters can affect the size of the etcd database in the hub cluster. In OpenShift Container Platform 4.8, when you delete a managed cluster, the etcd database in the hub cluster is not automatically reduced in size. In some scenarios, the etcd database can run out of space. An error etcdserver: mvcc: database space exceeded is displayed. To correct this error, reduce the size of the etcd database by compacting the database history and defragmenting the etcd database. Note: For OpenShift Container Platform version 4.9 and later, the etcd Operator automatically defragments disks and compacts the etcd history. No manual intervention is needed. The following procedure is for OpenShift Container Platform version 4.8 and earlier. Compact the etcd history and defragment the etcd database in the hub cluster by completing the following procedure. 1.6.19.4.1. Prerequisites Install the OpenShift CLI ( oc ). Log in as a user with cluster-admin privileges. 1.6.19.4.2. Procedure Compact the etcd history. Open a remote shell session to the etcd member, for example: USD oc rsh -n openshift-etcd etcd-control-plane-0.example.com etcdctl endpoint status --cluster -w table Run the following command to compact the etcd history: sh-4.4#etcdctl compact USD(etcdctl endpoint status --write-out="json" | egrep -o '"revision":[0-9]*' | egrep -o '[0-9]*' -m1) Example output USD compacted revision 158774421 Defragment the etcd database and clear any NOSPACE alarms as outlined in Defragmenting etcd data . 1.7. Discovery service introduction You can discover OpenShift 4 clusters that are available from OpenShift Cluster Manager . After discovery, you can import your clusters to manage. The Discovery services uses the Discover Operator for back-end and console usage. You must have an OpenShift Cluster Manager credential. See Creating a credential for Red Hat OpenShift Cluster Manager if you need to create a credential. Required access : Administrator Configure Discovery with the console Configure Discovery using the CLI Enabling a discovered cluster for management 1.7.1. Configure Discovery with the console Configure Discovery in the console to find clusters. When you configure the Discovery feature on your cluster, you must enable a DiscoveryConfig resource to connect to the OpenShift Cluster Manager to begin discovering clusters that are a part of your organization. You can create multiple DiscoveryConfig resources with separate credentials. After you discover clusters, you can import clusters that appear in the Discovered clusters tab of the console. Use the product console to enable Discovery. Required access : Access to the namespace where the credential was created. 1.7.1.1. Prerequisites You need a credential. See Creating a credential for Red Hat OpenShift Cluster Manager to connect to OpenShift Cluster Manager. You need access to the namespaces that were used to configure Discovery. 1.7.1.2. Import discovered clusters from the console To manually import other infrastructure provider discovered clusters, complete the following steps: Go to the existing Clusters page and click the Discovered clusters tab. From the Discovered clusters table, find the cluster that you want to import. From the options menu, choose Import cluster . For discovered clusters, you can import manually using the documentation, or you can choose Import clusters automatically. To import automatically with your credentials or Kubeconfig file, copy and paste the content. Click Import . 1.7.1.3. View discovered clusters After you set up your credentials and discover your clusters for import, you can view them in the console. Click Clusters > Discovered clusters View the populated table with the following information: Name is the display name that is designated in OpenShift Cluster Manager. If the cluster does not have a display name, a generated name based on the cluster console URL is displayed. If the console URL is missing or was modified manually in OpenShift Cluster Manager, the cluster external ID is displayed. Namespace is the namespace where you created the credential and discovered clusters. Type is the discovered cluster Red Hat OpenShift type. Distribution version is the discovered cluster Red Hat OpenShift version. Infrastructure provider is the cloud provider of the discovered cluster. Last active is the last time the discovered cluster was active. Created when the discovered cluster was created. Discovered when the discovered cluster was discovered. You can search for any information in the table, as well. For example, to show only Discovered clusters in a particular namespace, search for that namespace. You can now click Import cluster to create managed clusters. 1.7.2. Enable Discovery using the CLI Enable discovery using the CLI to find clusters that are available from Red Hat OpenShift Cluster Manager. Required access : Administrator 1.7.2.1. Prerequisites Create a credential to connect to Red Hat OpenShift Cluster Manager. 1.7.2.2. Discovery set up and process Note: The DiscoveryConfig must be named discovery and must be created in the same namespace as the selected credential . See the following DiscoveryConfig sample: apiVersion: discovery.open-cluster-management.io/v1 kind: DiscoveryConfig metadata: name: discovery namespace: <NAMESPACE_NAME> spec: credential: <SECRET_NAME> filters: lastActive: 7 openshiftVersions: - "4.14" Replace SECRET_NAME with the credential that you previously set up. Replace NAMESPACE_NAME with the namespace of SECRET_NAME . Enter the maximum time since last activity of your clusters (in days) to discover. For example, with lastActive: 7 , clusters that active in the last 7 days are discovered. Enter the versions of Red Hat OpenShift clusters to discover as a list of strings. Note: Every entry in the openshiftVersions list specifies an OpenShift major and minor version. For example, specifying "4.11" will include all patch releases for the OpenShift version 4.11 , for example 4.11.1 , 4.11.2 . 1.7.2.3. View discovered clusters View discovered clusters by running oc get discoveredclusters -n <namespace> where namespace is the namespace where the discovery credential exists. 1.7.2.3.1. DiscoveredClusters Objects are created by the Discovery controller. These DiscoveredClusters represent the clusters that are found in OpenShift Cluster Manager by using the filters and credentials that are specified in the DiscoveryConfig discoveredclusters.discovery.open-cluster-management.io API. The value for name is the cluster external ID: apiVersion: discovery.open-cluster-management.io/v1 kind: DiscoveredCluster metadata: name: fd51aafa-95a8-41f7-a992-6fb95eed3c8e namespace: <NAMESPACE_NAME> spec: activity_timestamp: "2021-04-19T21:06:14Z" cloudProvider: vsphere console: https://console-openshift-console.apps.qe1-vmware-pkt.dev02.red-chesterfield.com creation_timestamp: "2021-04-19T16:29:53Z" credential: apiVersion: v1 kind: Secret name: <SECRET_NAME> namespace: <NAMESPACE_NAME> display_name: qe1-vmware-pkt.dev02.red-chesterfield.com name: fd51aafa-95a8-41f7-a992-6fb95eed3c8e openshiftVersion: 4.14 status: Stale 1.7.3. Enabling a discovered cluster for management Automatically import supported clusters into your hub cluster with the Discovery-Operator for faster cluster management, without manually importing individual clusters. Required access: Cluster administrator 1.7.3.1. Prerequisite Discovery is enabled by default. If you changed default settings, you need to enable Discovery. You must set up the OpenShift Service on AWS command line interface. See Getting started with the OpenShift Service on AWS CLI documentation. 1.7.3.2. Importing discovered OpenShift Service on AWS and hosted control plane clusters automatically The following procedure is an example of how to import your discovered OpenShift Service on AWS and hosted control planes clusters automatically by using the Discovery-Operator . 1.7.3.2.1. Importing from the console To automatically import the DiscoveredCluster resource, you must modify the resource and set the importAsManagedCluster field to true in the console. See the following procedure: Log in to your hub cluster from the console. Select Search from the navigation menu. From the search bar, enter the following query: "DiscoveredCluster". The DiscoveredCluster resource results appear. Go to the DiscoveredCluster resource and set importAsManagedCluster to true . See the following example, where importAsManagedCluster is set to true and <4.x.z> is your supported OpenShift Container Platform version: apiVersion: discovery.open-cluster-management.io/v1 kind: DiscoveredCluster metadata: name: 28c17977-fc73-4050-b5cc-a5aa2d1d6892 namespace: discovery spec: openshiftVersion: <4.x.z> isManagedCluster: false cloudProvider: aws name: 28c17977-fc73-4050-b5cc-a5aa2d1d6892 displayName: rosa-dc status: Active importAsManagedCluster: true 1 type: <supported-type> 2 1 By setting the field to true , the Discovery-Operator imports the DiscoveredCluster resource, creates a ManagedCluster resource and if the Red Hat Advanced Cluster Management is installed, creates the KlusterletAddOnConfig resource. It also creates the Secret resources for your automatic import. 2 You must use ROSA or MultiClusterEngineHCP as the parameter value. To verify that the DiscoveredCluster resource is imported, go to the Clusters page. Check the import status of your cluster from the Cluster list tab. If you want to detach managed clusters for Discovery to prevent automatic reimport, select the Detach cluster option. The Discovery-Operator adds the following annotation, discovery.open-cluster-management.io/previously-auto-imported: 'true' . Your DiscoveredCluster resource might resemble the following YAML: apiVersion: discovery.open-cluster-management.io/v1 kind: DiscoveredCluster metadata: annotations: discovery.open-cluster-management.io/previously-auto-imported: 'true' To verify that the DiscoveredCluster resource is not reimported automatically, check for the following message in the Discovery-Operator logs, where "rosa-dc" is this discovered cluster: 2024-06-12T14:11:43.366Z INFO reconcile Skipped automatic import for DiscoveredCluster due to existing 'discovery.open-cluster-management.io/previously-auto-imported' annotation {"Name": "rosa-dc"} If you want to reimport the DiscoveredCluster resource automatically, you must remove the previously mentioned annotation. 1.7.3.2.2. Importing from the command line interface To automatically import the DiscoveredCluster resource from the command line complete the following steps: To automatically import the DiscoveredCluster resource, set the importAsManagedCluster paramater to true by using the following command after you log in. Replace <name> and <namespace> with your name and namespace: oc patch discoveredcluster <name> -n <namespace> --type='json' -p='[{"op": "replace", "path": "/spec/importAsManagedCluster", "value": true}]' Run the following command to verify that the cluster was imported as a managed cluster: oc get managedcluster <name> To get a description of your OpenShift Service on AWS cluster ID, run the following command from the OpenShift Service on AWS command line interface: rosa describe cluster --cluster=<cluster-name> | grep -o '^ID:.* For other Kubernetes providers, you must import these infrastructure provider DiscoveredCluster resources manually. Directly apply Kubernetes configurations to the other types of DiscoveredCluster resources. If you enable the importAsManagedCluster field from the DiscoveredCluster resource, it is not imported due to the Discovery webhook. 1.7.3.3. Additional resources See Discovery service introduction . 1.8. Hosted control planes With multicluster engine operator cluster management, you can deploy OpenShift Container Platform clusters by using two different control plane configurations: standalone or hosted control planes. The standalone configuration uses dedicated virtual machines or physical machines to host the OpenShift Container Platform control plane. With hosted control planes for OpenShift Container Platform, you create control planes as pods on a hosting cluster without the need for dedicated physical machines for each control plane. Hosted control planes for OpenShift Container Platform are available on Amazon Web Services (AWS), IBM Power, IBM Z, Red Hat OpenShift Virtualization, bare metal, and non bare metal agent machines. The hosted control planes feature is enabled by default. Hosted control plane clusters offer several advantages: Saves cost by removing the need to host dedicated control plane nodes Introduces separation between the control plane and the workloads, which improves isolation and reduces configuration errors that can require changes Decreases the cluster creation time by removing the requirement for control plane node bootstrapping Supports turn-key deployments or fully customized OpenShift Container Platform provisioning 1.8.1. Requirements The hosting cluster and workers must run on the same infrastructure. For example, you cannot run your hosting cluster on bare metal and your workers on the cloud. However, the hub cluster and workers do not need to run on the same platform. For example, you might run your hosting cluster on bare metal and workers on OpenShift Virtualization. The control plane is associated with a hosted cluster and runs as pods in a single namespace. When the cluster service consumer creates a hosted cluster, it creates a worker node that is independent of the control plane. If you are using a proxy and you want traffic from pods to the Kubernetes API server to not use the proxy, add the default Kubernetes API server address, 172.20.0.1, to the no_proxy list. The following table indicates which OpenShift Container Platform versions are supported for each platform. In the table, Hosting OpenShift Container Platform version refers to the OpenShift Container Platform version where multicluster engine operator is enabled: Platform Hosting OpenShift Container Platform version Hosted OpenShift Container Platform version AWS 4.11 - 4.16 4.14 - 4.16 (only) IBM Power 4.16 4.16 (only) IBM Z 4.16 4.16 (only) Red Hat OpenShift Virtualization 4.14 - 4.16 4.14 - 4.16 (only) Bare metal 4.14 - 4.16 4.14 - 4.16 (only) Non bare metal agent machines 4.16 4.16 (only) 1.8.1.1.

Hosted control plane sizing guidance Many factors, including hosted cluster workload and worker node count, affect how many hosted clusters can fit within a certain number of control-plane nodes. Use this sizing guide to help with hosted cluster capacity planning. This guidance assumes a highly available hosted control plane topology. The load-based sizing examples were measured on a bare-metal cluster. Cloud-based instances might have different limiting factors, such as memory size. For more information about highly available hosted control plane topology, see Distributing hosted cluster workloads . You can override the following resource utilization sizing measurements and disable the metric service monitoring. For more information, see Overriding resource utilization measurements in the Additional resources section. See the following highly available hosted control plane requirements, which were tested with OpenShift Container Platform version 4.12.9 and later: 78 pods Three 8 GiB PVs for etcd Minimum vCPU: approximately 5.5 cores Minimum memory: approximately 19 GiB 1.8.2.1. Pod limits The maxPods setting for each node affects how many hosted clusters can fit in a control-plane node. It is important to note the maxPods value on all control-plane nodes. Plan for about 75 pods for each highly available hosted control plane. For bare-metal nodes, the default maxPods setting of 250 is likely to be a limiting factor because roughly three hosted control planes fit for each node given the pod requirements, even if the machine has plenty of resources to spare. Setting the maxPods value to 500 by configuring the KubeletConfig value allows for greater hosted control plane density, which can help you take advantage of additional compute resources. For more information, see Configuring the maximum number of pods per node in the OpenShift Container Platform documentation. 1.8.2.2. Request-based resource limit The maximum number of hosted control planes that the cluster can host is calculated based on the hosted control plane CPU and memory requests from the pods. A highly available hosted control plane consists of 78 pods that request 5 vCPUs and 18 GB memory. These baseline numbers are compared to the cluster worker node resource capacities to estimate the maximum number of hosted control planes. 1.8.2.3. Load-based limit The maximum number of hosted control planes that the cluster can host is calculated based on the hosted control plane pods CPU and memory utilizations when some workload is put on the hosted control plane Kubernetes API server. The following method is used to measure the hosted control plane resource utilizations as the workload increases: A hosted cluster with 9 workers that use 8 vCPU and 32 GiB each, while using the KubeVirt platform The workload test profile that is configured to focus on API control-plane stress, based on the following definition: Created objects for each namespace, scaling up to 100 namespaces total Additional API stress with continuous object deletion and creation Workload queries-per-second (QPS) and Burst settings set high to remove any client-side throttling As the load increases by 1000 QPS, the hosted control plane resource utilization increases by 9 vCPUs and 2.5 GB memory. For general sizing purposes, consider the 1000 QPS API rate that is a medium hosted cluster load, and a 2000 QPS API that is a heavy hosted cluster load. Note: This test provides an estimation factor to increase the compute resource utilization based on the expected API load. Exact utilization rates can vary based on the type and pace of the cluster workload. Table 1.8. Load table Hosted control plane resource utilization scaling vCPUs Memory (GiB) Resource utilization with no load 2.9 11.1 Resource utilization with 1000 QPS 9.0 2.5 As the load increases by 1000 QPS, the hosted control plane resource utilization increases by 9 vCPUs and 2.5 GB memory. For general sizing purposes, consider a 1000 QPS API rate to be a medium hosted cluster load and a 2000 QPS API to be a heavy hosted cluster load. The following example shows hosted control plane resource scaling for the workload and API rate definitions: Table 1.9. API rate table QPS (API rate) vCPU usage Memory usage (GiB) Low load (Less than 50 QPS) 2.9 11.1 Medium load (1000 QPS) 11.9 13.6 High load (2000 QPS) 20.9 16.1 The hosted control plane sizing is about control-plane load and workloads that cause heavy API activity, etcd activity, or both. Hosted pod workloads that focus on data-plane loads, such as running a database, might not result in high API rates. 1.8.2.4. Sizing calculation example This example provides sizing guidance for the following scenario: Three bare-metal workers that are labeled as hypershift.openshift.io/control-plane nodes maxPods value set to 500 The expected API rate is medium or about 1000, according to the load-based limits Table 1.10.

Additional resources Distribute hosted cluster workloads Configuring the maximum number of pods per node Overriding resource utilization measurements 1.8.3. Overriding resource utilization measurements The set of baseline measurements for resource utilization can vary in every cluster. Fore more information, see Hosted control plane sizing guidance . You can override the resource utilization measurements based on the type and pace of your cluster workload. Complete the following steps: Create the ConfigMap resource by running the following command: Replace <your-config-map-file.yaml> with the name of your YAML file that contains your hcp-sizing-baseline config map. Create the hcp-sizing-baseline config map in the local-cluster namespace to specify the measurements you want to override. Your config map might resemble the following YAML file: kind: ConfigMap apiVersion: v1 metadata: name: hcp-sizing-baseline namespace: local-cluster data: incrementalCPUUsagePer1KQPS: "9.0" memoryRequestPerHCP: "18" minimumQPSPerHCP: "50.0" Delete the hypershift-addon-agent deployment to restart the hypershift-addon-agent pod by running the following command: Observe the hypershift-addon-agent pod logs. Verify that the overridden measurements are updated in the config map by running the following command: Your logs might resemble the following output: If the overridden measurements are not updated properly in the hcp-sizing-baseline config map, you might see the following error message in the hypershift-addon-agent pod logs: 1.8.3.1. Disabling the metric service monitoring After enabling the hypershift-addon managed cluster addon, the metric service monitoring is configured by default so that OpenShift Container Platform monitoring can gather metrics from hypershift-addon . You can disable the metric service monitoring by completing the following steps: Log in to your hub cluster by running the following command: Open the hypershift-addon-deploy-config add-on deployment configuration specification for editing by running the following command: Add the disableMetrics=true customized variable to the specification, as shown in the following example: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: AddOnDeploymentConfig metadata: name: hypershift-addon-deploy-config namespace: multicluster-engine spec: customizedVariables: - name: hcMaxNumber value: "80" - name: hcThresholdNumber value: "60" - name: disableMetrics value: "true" Save the changes. The disableMetrics=true customized variable disables the metric service monitoring configuration for both new and existing hypershift-addon managed cluster add-ons. 1.8.3.2. Additional resources Hosted control plane sizing guidance 1.8.4. Installing the hosted control plane command line interface The hosted control plane command line interface, hcp , is a tool that you can use to get started with hosted control planes. For Day 2 operations, such as management and configuration, use GitOps or your own automation tool. You can install the hosted control plane command line interface, hcp , by completing the following steps: From the OpenShift Container Platform console, click the Help icon > Command Line Tools . Click Download hcp CLI for your platform. Unpack the downloaded archive by running the following command: Run the following command to make the binary file executable: Run the following command to move the binary file to a directory in your path: You can now use the hcp create cluster command to create and manage hosted clusters. To list the available parameters, enter the following command: 1 The supported platforms are aws , agent , and kubevirt . 1.8.4.1. Installing the hosted control plane command line interface by using the CLI You can install the hosted control plane command line interface, hcp , by using the CLI, by completing the following steps: Get the URL to download the hcp binary by running the following command: Download the hcp binary by running the following command: 1 Replace hcp_cli_download_url with the URL that you obtained from the step. Unpack the downloaded archive by running the following command: Run the following command to make the binary file executable: Run the following command to move the binary file to a directory in your path: 1.8.4.2. Installing the hosted control plane command line interface by using the content gateway You can install the hosted control plane command line interface, hcp , by using the content gateway. Complete the following steps: Navigate to the content gateway and download the hcp binary. Unpack the downloaded archive by running the following command: Run the following command to make the binary file executable: Run the following command to move the binary file to a directory in your path: You can now use the hcp create cluster command to create and manage hosted clusters. To list the available parameters, enter the following command: 1 The supported platforms are aws , agent , and kubevirt . 1.8.5. Distributing hosted cluster workloads Before you get started with hosted control planes for OpenShift Container Platform, you must properly label nodes so that the pods of hosted clusters can be scheduled into infrastructure nodes. Node labeling is also important for the following reasons: To ensure high availability and proper workload deployment. For example, you can set the node-role.kubernetes.io/infra label to avoid having the control-plane workload count toward your OpenShift Container Platform subscription. To ensure that control plane workloads are separate from other workloads in the management cluster. Important: Do not use the management cluster for your workload. Workloads must not run on nodes where control planes run. 1.8.5.1. Labels and taints for management cluster nodes As a management cluster administrator, use the following labels and taints in management cluster nodes to schedule a control plane workload: hypershift.openshift.io/control-plane: true : Use this label and taint to dedicate a node to running hosted control plane workloads. By setting a value of true , you avoid sharing the control plane nodes with other components, for example, the infrastructure components of the management cluster or any other mistakenly deployed workload. hypershift.openshift.io/cluster: USD{HostedControlPlane Namespace} : Use this label and taint when you want to dedicate a node to a single hosted cluster. Apply the following labels on the nodes that host control-plane pods: node-role.kubernetes.io/infra : Use this label to avoid having the control-plane workload count toward your subscription. topology.kubernetes.io/zone : Use this label on the management cluster nodes to deploy highly available clusters across failure domains. The zone might be a location, rack name, or the hostname of the node where the zone is set. For example, a management cluster has the following nodes: worker-1a , worker-1b , worker-2a , and worker-2b . The worker-1a and worker-1b nodes are in rack1 , and the worker-2a and worker-2b nodes are in rack2 . To use each rack as an availability zone, enter the following commands: Pods for a hosted cluster have tolerations, and the scheduler uses affinity rules to schedule them. Pods tolerate taints for control-plane and the cluster for the pods. The scheduler prioritizes the scheduling of pods into nodes that are labeled with hypershift.openshift.io/control-plane and hypershift.openshift.io/cluster: USD{HostedControlPlane Namespace} . For the ControllerAvailabilityPolicy option, use HighlyAvailable , which is the default value that the hosted control planes command line interface, hcp , deploys. When you use that option, you can schedule pods for each deployment within a hosted cluster across different failure domains by setting topology.kubernetes.io/zone as the topology key. Control planes that are not highly available are not supported. Important: Proper node labeling, which is detailed in the following procedure, is a prerequisite to deploying hosted control planes. 1.8.5.2. Labeling nodes for hosted clusters To enable a hosted cluster to require its pods to be scheduled into infrastructure nodes, set HostedCluster.spec.nodeSelector , as shown in the following example: spec: nodeSelector: role.kubernetes.io/infra: "" This way, hosted control planes for each hosted cluster are eligible infrastructure node workloads, and you do not need to entitle the underlying OpenShift Container Platform nodes. 1.8.5.3. Priority classes Four built-in priority classes influence the priority and preemption of the hosted cluster pods. You can create the pods in the management cluster in the following order from highest to lowest: hypershift-operator : HyperShift Operator pods. hypershift-etcd : Pods for etcd. hypershift-api-critical : Pods that are required for API calls and resource admission to succeed. These pods include pods such as kube-apiserver , aggregated API servers, and web hooks. hypershift-control-plane : Pods in the control plane that are not API-critical but still need elevated priority, such as the cluster version Operator. 1.8.5.4. Additional resources For more information about hosted control planes, see the following topics: Configuring hosted control plane clusters on bare metal Managing hosted control plane clusters on OpenShift Virtualization Configuring hosted control plane clusters on AWS 1.8.6. Configuring hosted control plane clusters on AWS To configure hosted control planes, you need a hosting cluster and a hosted cluster. By deploying the HyperShift Operator on an existing managed cluster by using the hypershift-addon managed cluster add-on, you can enable that cluster as a hosting cluster and start to create the hosted cluster. The hypershift-addon managed cluster add-on is enabled by default for the local-cluster managed cluster. A hosted cluster is an OpenShift Container Platform cluster with its API endpoint and control plane that are hosted on the hosting cluster. The hosted cluster includes the control plane and its corresponding data plane. You can use the multicluster engine operator console or the hosted control plane command line interface, hcp , to create a hosted cluster. The hosted cluster is automatically imported as a managed cluster. If you want to disable this automatic import feature, see Disabling the automatic import of hosted clusters into multicluster engine operator . Important: Each hosted cluster must have a cluster-wide unique name. A hosted cluster name cannot be the same as any existing managed cluster in order for multicluster engine operator to manage it. Do not use clusters as a hosted cluster name. Run the hub cluster and workers on the same platform for hosted control planes. A hosted cluster cannot be created in the namespace of a multicluster engine operator managed cluster. 1.8.6.1. Prerequisites You must have the following prerequisites to configure a hosting cluster: The multicluster engine for Kubernetes operator 2.5 and later installed on an OpenShift Container Platform cluster. The multicluster engine operator is automatically installed when you install Red Hat Advanced Cluster Management. The multicluster engine operator can also be installed without Red Hat Advanced Cluster Management as an Operator from the OpenShift Container Platform OperatorHub. The multicluster engine operator must have at least one managed OpenShift Container Platform cluster. The local-cluster is automatically imported in multicluster engine operator 2.5 and later. See Advanced configuration for more information about the local-cluster . You can check the status of your hub cluster by running the following command: The AWS command line interface The hosted control plane command line interface For additional resources about hosted control planes, see the following documentation: To disable the hosted control planes feature or, if you already disabled it and want to manually enable it, see Enabling or disabling the hosted control planes feature . To manage hosted clusters by running Red Hat Ansible Automation Platform jobs, see Configuring Ansible Automation Platform jobs to run on hosted clusters . To deploy the SR-IOV Operator, see Deploying the SR-IOV Operator for hosted control planes . 1.8.6.2. Creating the Amazon Web Services S3 bucket and S3 OIDC secret If you plan to create and manage hosted clusters on AWS, complete the following steps: Create an S3 bucket that has public access to host OIDC discovery documents for your clusters. To create the bucket in the us-east-1 region, enter the following code: To create the bucket in a region other than the us-east-1 region, enter the following code: Create an OIDC S3 secret named hypershift-operator-oidc-provider-s3-credentials for the HyperShift operator. Save the secret in the local-cluster namespace. See the following table to verify that the secret contains the following fields: Field name Description bucket Contains an S3 bucket with public access to host OIDC discovery documents for your hosted clusters. credentials A reference to a file that contains the credentials of the default profile that can access the bucket. By default, HyperShift only uses the default profile to operate the bucket . region Specifies the region of the S3 bucket. The following example shows a sample AWS secret template: Note: Disaster recovery backup for the secret is not automatically enabled. Run the following command to add the label that enables the hypershift-operator-oidc-provider-s3-credentials secret to be backed up for disaster recovery: 1.8.6.3. Creating a routable public zone To access applications in your guest clusters, the public zone must be routable. If the public zone exists, skip this step. Otherwise, the public zone will affect the existing functions. Run the following command to create a public zone for cluster DNS records: Replace your-basedomain with your base domain, for example, www.example.com . 1.8.6.4. Creating an AWS IAM role and STS credentials Before creating hosted clusters on Amazon Web Services (AWS), you must create AWS Security Token Service (STS) credentials and an AWS Identity and Access Management (IAM) role for the hcp command line interface (CLI). Get the Amazon Resource Name (ARN) of your user by running the following command: aws sts get-caller-identity --query "Arn" --output text See the following example output: You need the arn value from the output to use in the step. Create a JSON file named trust-relationship.json that contains the trust relationship configuration for your role. Replace <arn> with the ARN of your user that you noted in the step.

Retrieve STS credentials in a JSON file named sts-creds.json by running the following command: aws sts get-session-token --output json > sts-creds.json See the following example content of the sts-creds.json file : 1.8.6.5. Enabling external DNS The control plane and the data plane are separate in hosted control planes. You can configure DNS in two independent areas: Ingress for workloads within the hosted cluster, such as the following domain: *.apps.service-consumer-domain.com Ingress for service endpoints within the management cluster, such as API or OAUTH endpoints through the service provider domain: *.service-provider-domain.com The input for the hostedCluster.spec.dns manages the ingress for workloads within the hosted cluster. The input for hostedCluster.spec.services.servicePublishingStrategy.route.hostname manages the ingress for service endpoints within the management cluster. External DNS creates name records for hosted cluster Services that specify a publishing type of LoadBalancer or Route and provide a hostname for that publishing type. For hosted clusters with Private or PublicAndPrivate endpoint access types, only the APIServer and OAuth services support hostnames. For Private hosted clusters, the DNS record resolves to a private IP address of a Virtual Private Cloud (VPC) endpoint in your VPC. A hosted control plane exposes the following services: APIServer OAuthServer Konnectivity Ignition OVNSbDb OIDC You can expose these services by using the servicePublishingStrategy field in the HostedCluster specification. By default, for the LoadBalancer and Route types of servicePublishingStrategy , you can publish the service in one of the following ways: By using the hostname of the load balancer that is in the status of the Service with the LoadBalancer type By using the status.host field of the Route resource However, when you deploy hosted control planes in a managed service context, those methods can expose the ingress subdomain of the underlying management cluster and limit options for the management cluster lifecycle and disaster recovery. When a DNS indirection is layered on the LoadBalancer and Route publishing types, a managed service operator can publish all public hosted cluster services by using a service-level domain. This architecture allows remapping on the DNS name to a new LoadBalancer or Route and does not expose the ingress domain of the management cluster. Hosted control planes uses external DNS to achieve that indirection layer. You can deploy external-dns alongside the HyperShift Operator in the hypershift namespace of the management cluster. External DNS watches for Services or Routes that have the external-dns.alpha.kubernetes.io/hostname annotation. That annotation is used to create a DNS record that points to the Service , such as a record, or the Route , such as a CNAME record. You can use external DNS on cloud environments only. For the other environments, you need to manually configure DNS and services. For more information about external DNS, see external DNS . 1.8.6.5.1. Prerequisites Before you can set up external DNS for hosted control planes, you must meet the following prerequisites: You created an external public domain You have access to the AWS Route53 Management console 1.8.6.5.2. Setting up external DNS for hosted control planes To provision hosted control plane clusters with service-level DNS (external DNS), complete the following steps: Create an AWS credential secret for the HyperShift Operator and name it hypershift-operator-external-dns-credentials in the local-cluster namespace. See the following table to verify that the secret has the required fields: Field name Description Optional or required provider The DNS provider that manages the service-level DNS zone. Required domain-filter The service-level domain. Required credentials The credential file that supports all external DNS types. Optional when you use AWS keys aws-access-key-id The credential access key id. Optional when you use the AWS DNS service aws-secret-access-key The credential access key secret. Optional when you use the AWS DNS service The following example shows the sample hypershift-operator-external-dns-credentials secret template: oc create secret generic hypershift-operator-external-dns-credentials --from-literal=provider=aws --from-literal=domain-filter=<domain_name> --from-file=credentials=<path_to_aws_credentials_file> -n local-cluster Note: Disaster recovery backup for the secret is not automatically enabled. To back up the secret for disaster recovery, add the hypershift-operator-external-dns-credentials by entering the following command: oc label secret hypershift-operator-external-dns-credentials -n local-cluster cluster.open-cluster-management.io/backup="" 1.8.6.5.3. Creating the public DNS hosted zone The External DNS Operator uses the public DNS hosted zone to create your public hosted cluster. You can create the public DNS hosted zone to use as the external DNS domain-filter. Complete the following steps in the AWS Route 53 management console: In the Route 53 management console, click Create hosted zone . On the Hosted zone configuration page, type a domain name, verify that Publish hosted zone is selected as the type, and click Create hosted zone . After the zone is created, on the Records tab, note the values in the Value/Route traffic to column. In the main domain, create an NS record to redirect the DNS requests to the delegated zone. In the Value field, enter the values that you noted in the step. Click Create records . Verify that the DNS hosted zone is working by creating a test entry in the new subzone and testing it with a dig command like the following example: To create a hosted cluster that sets the hostname for LoadBalancer and Route services, enter the following command: Replace <public_hosted_zone> with the public hosted zone that you created. This example shows the resulting services block for the hosted cluster: platform: aws: endpointAccess: PublicAndPrivate ... services: - service: APIServer servicePublishingStrategy: route: hostname: api-example.service-provider-domain.com type: Route - service: OAuthServer servicePublishingStrategy: route: hostname: oauth-example.service-provider-domain.com type: Route - service: Konnectivity servicePublishingStrategy: type: Route - service: Ignition servicePublishingStrategy: type: Route The Control Plane Operator creates the Services and Routes resources and annotates them with the external-dns.alpha.kubernetes.io/hostname annotation. For Services and Routes , the Control Plane Operator uses a value of the hostname parameter in the servicePublishingStrategy field for the service endpoints. To create the DNS records, you can use a mechanism, such as the external-dns deployment. You can configure service-level DNS indirection for public services only. You cannot set hostname for private services because they use the hypershift.local private zone. The following table notes when it is valid to set hostname for a service and endpoint combination: Service Public PublicAndPrivate Private APIServer Y Y N OAuthServer Y Y N Konnectivity Y N N Ignition Y N N 1.8.6.5.4. Deploying a cluster by using the command line interface and external DNS To create a hosted cluster by using the PublicAndPrivate or Public publishing strategy, you must have the following artifacts configured in your management cluster: The public DNS hosted zone The External DNS Operator The HyperShift Operator To deploy a hosted cluster by using the command line interface, complete the following steps: To access your management cluster, enter the following command: export KUBECONFIG=<path_to_management_cluster_kubeconfig> Verify that the External DNS Operator is running by entering the following command: oc get pod -n hypershift -lapp=external-dns See the following example output: To create a hosted cluster by using external DNS, enter the following command: hcp create cluster aws \ --role-arn <arn_role> \ 1 --instance-type <instance_type> \ 2 --region <region> \ 3 --auto-repair \ --generate-ssh \ --name <hosted_cluster_name> \ 4 --namespace clusters \ --base-domain <service_consumer_domain> \ 5 --node-pool-replicas <node_replica_count> \ 6 --pull-secret <path_to_your_pull_secret> \ 7 --release-image quay.io/openshift-release-dev/ocp-release:<ocp_release_image> \ 8 --external-dns-domain=<service_provider_domain> \ 9 --endpoint-access=PublicAndPrivate 10 --sts-creds <path_to_sts_credential_file> 11 1 Specify the Amazon Resource Name (ARN), for example, arn:aws:iam::820196288204:role/myrole . 2 Specify the instance type, for example, m6i.xlarge . 3 Specify the AWS region, for example, us-east-1 . 4 Specify your hosted cluster name, for example, my-external-aws . 5 Specify the public hosted zone that the service consumer owns, for example, service-consumer-domain.com . 6 Specify the node replica count, for example, 2 . 7 Specify the path to your pull secret file. 8 Specify the supported OpenShift Container Platform version that you want to use, for example, 4.14.0-x86_64 . 9 Specify the public hosted zone that the service provider owns, for example, service-provider-domain.com . 10 Set as PublicAndPrivate . You can use external DNS with Public or PublicAndPrivate configurations only. 11 Specify the path to your AWS STS credentials file, for example, /home/user/sts-creds/sts-creds.json . 1.8.6.6. Enabling AWS PrivateLink If you plan to provision hosted control plane clusters on the AWS platform with PrivateLink, complete the following steps: Create an AWS credential secret for the HyperShift Operator and name it hypershift-operator-private-link-credentials . The secret must reside in the managed cluster namespace that is the namespace of the managed cluster being used as the hosting cluster. If you used local-cluster , create the secret in the local-cluster namespace. See the following table to confirm that the secret contains the required fields: Field name Description Optional or required region Region for use with Private Link Required aws-access-key-id The credential access key id. Required aws-secret-access-key The credential access key secret. Required The following example shows the sample hypershift-operator-private-link-credentials secret template: Note: Disaster recovery backup for the secret is not automatically enabled. Run the following command to add the label that enables the hypershift-operator-private-link-credentials secret to be backed up for disaster recovery: 1.8.6.7. Disaster recovery for a hosted cluster The hosted control plane runs on the multicluster engine operator hub cluster. The data plane runs on a separate platform that you choose. When recovering the multicluster engine operator hub cluster from a disaster, you might also want to recover the hosted control planes. See Disaster recovery for a hosted cluster within an AWS region to learn how to back up a hosted control plane cluster and restore it on a different cluster. Important: Disaster recovery for hosted clusters is available on AWS only. 1.8.6.8. Deploying a hosted cluster on AWS Before you deploy a hosted cluster on Amazon Web Services (AWS), you must perform the following actions: Set up the hosted control plane command line interface, hcp . Enable the local-cluster managed cluster as the hosting cluster. Create an AWS Identity and Access Management (IAM) role and AWS Security Token Service (STS) credentials. See Creating an AWS IAM role and STS credentials . If you want to deploy a private hosted cluster, see Deploying a private hosted cluster on AWS .

Additional resources For instructions to install the AWS Elastic File Service (EFS) CSI Driver Operator on a hosted cluster, see Configuring AWS EFS CSI Driver Operator with Security Token Service . 1.8.6.10. Enabling hosted clusters to run on different architectures (Technology Preview) By default for hosted control planes on AWS, you use an AMD64 hosted cluster. However, you can enable hosted control planes to run on an ARM64 hosted cluster. You can also create node pools of different architecture types for the same hosted cluster. See the following table for compatible combinations of node pools and hosted clusters: Hosted cluster Node pool AMD64 AMD64 or ARM64 ARM64 ARM64 or AMD64 1.8.6.10.1. Prerequisites You must have an OpenShift Container Platform cluster with a 64-bit ARM infrastructure that is installed on Amazon Web Serivces (AWS). For more information, see Create an OpenShift Cluster: AWS (ARM) . You must create an AWS Identity and Access Management (IAM) role and AWS Security Token Service (STS) credentials. See Creating an AWS IAM role and STS credentials . 1.8.6.10.2. Running a hosted cluster on an ARM64 OpenShift Container Platform cluster You can run a hosted cluster on an ARM64 OpenShift Container Platform cluster by overriding the default release image with a multi-architecture release image. Complete the following steps: Create a hosted cluster by running the following command: hcp create cluster aws \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <node_pool_replica_count> \ 2 --base-domain <basedomain> \ 3 --pull-secret <path_to_pull_secret> \ 4 --sts-creds <path_to_sts_credential_file> \ 5 --region <region> \ 6 --release-image quay.io/openshift-release-dev/ocp-release:<ocp_release_image> \ 7 --role-arn <role_name> \ 8 --multi-arch 9 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the node pool replica count, for example, 3 . 3 Specify your base domain, for example, example.com . 4 Specify the path to your pull secret, for example, /user/name/pullsecret . 5 Specify the path to your AWS STS credentials file, for example, /home/user/sts-creds/sts-creds.json . 6 Specify the AWS region name, for example, us-east-1 . 7 Specify the supported OpenShift Container Platform version that you want to use, for example, 4.14.0-x86_64 .

When you set the flag and supply a release image or release stream, the release image or stream must be a multi-architecture release image or stream. If you do not set the multi-arch flag and you use a multi-architecture release image or stream, the CLI automatically sets the flag to true and generates a log message. A node pool supports only one CPU architecture within the same node pool. Add a NodePool object to the hosted cluster by running the following command: hcp create nodepool aws \ --cluster-name <hosted_cluster_name> \ 1 --name <nodepool_name> \ 2 --node-count <node_pool_replica_count> 3 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the node pool name. 3 Specify the node pool replica count, for example, 3 . 1.8.6.10.3. Creating ARM NodePool objects on AWS hosted clusters You can schedule application workloads ( NodePool objects) on 64-bit ARM and AMD64 from the same hosted control plane. You can define the arch field in the NodePool specification to set the required processor architecture for the NodePool object. The valid values for the arch field are as follows: arm64 amd64 If you do not specify a value for the arch field, the amd64 value is used by default. 1.8.6.10.3.1. Prerequisites You must have a multi-architecture image for the HostedCluster custom resource to use. You can access multi-architecture nightly images at https://multi.ocp.releases.ci.openshift.org/ . 1.8.6.10.3.2. Creating an ARM or AMD NodePool object on an AWS hosted cluster To create an ARM or AMD NodePool object on a hosted cluster on AWS, complete the following steps: Add a NodePool object to the hosted cluster by running the following command: hcp create nodepool aws \ --cluster-name <hosted_cluster_name> \ 1 --name <node_pool_name> \ 2 --node-count <node_pool_replica_count> 3 --arch <architecture> 4 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the node pool name. 3 Specify the node pool replica count, for example, 3 . 4 Specify the architecture type, such as arm64 or amd64 . 1.8.6.11. Accessing the hosted cluster You can access the hosted cluster by either getting the kubeconfig file and kubeadmin credential directly from resources, or by using the hcp command line interface to generate a kubeconfig file. To access the hosted cluster by getting the kubeconfig file and credentials directly from resources, you need to be familiar with the access secrets for hosted control plane clusters. The secrets are stored in the hosted cluster (hosting) namespace. The hosted cluster (hosting) namespace contains hosted cluster resources, and the hosted control plane namespace is where the hosted control plane runs. The secret name formats are as follows: kubeconfig secret: <hosted-cluster-namespace>-<name>-admin-kubeconfig (clusters-hypershift-demo-admin-kubeconfig) kubeadmin password secret: <hosted-cluster-namespace>-<name>-kubeadmin-password (clusters-hypershift-demo-kubeadmin-password) The kubeconfig secret contains a Base64-encoded kubeconfig field, which you can decode and save into a file to use with the following command: The kubeadmin password secret is also Base64-encoded. You can decode it and use the password to log in to the API server or console of the hosted cluster. To access the hosted cluster by using the hcp CLI to generate the kubeconfig file, take the following steps: Generate the kubeconfig file by entering the following command: After you save the kubeconfig file, you can access the hosted cluster by entering the following example command: 1.8.6.11.1. Additional resources After you access the hosted cluster, you can scale a node pool or enable node auto-scaling for the hosted cluster. For more information, read these topics: Scaling a node pool Enabling node auto-scaling for the hosted cluster To configure node tuning for a hosted cluster, see the following topics: Configuring node tuning in a hosted cluster Advanced node tuning for hosted clusters by setting kernel boot parameters . 1.8.6.12. Deploying a private hosted cluster on AWS After you set up the hosted control planes command line interface, hcp , and enable the local-cluster as the hosting cluster, you can deploy a hosted cluster or a private hosted cluster on Amazon Web Services (AWS). To deploy a public hosted cluster on AWS, see Deploying a hosted cluster on AWS . By default, hosted control plane guest clusters are publicly accessible through public DNS and the default router for the management cluster. For private clusters on AWS, all communication with the guest cluster occurs over AWS PrivateLink. To configure hosted control planes for private cluster support on AWS, take the following steps. Important: Although public clusters can be created in any region, you can create private clusters only in the region that is specified by the --aws-private-region flag. Prerequisites Creating a private hosted cluster on AWS Accessing a private hosting cluster on AWS 1.8.6.12.1. Prerequisites To enable private hosted clusters for AWS, you must first enable AWS PrivateLink. For more information, see Enabling AWS PrivateLink . You must create an AWS Identity and Access Management (IAM) role and AWS Security Token Service (STS) credentials. For more information, see Creating an AWS IAM role and STS credentials and Identity and Access Management (IAM) permissions . To access a private cluster, you need a bastion instance on AWS. For more information, see Linux Bastion Hosts on AWS in the AWS documentation. 1.8.6.12.2. Creating a private hosted cluster on AWS To create a private hosted cluster on AWS, complete the following steps: Create a private hosted cluster by entering the following command, replacing variables with your values as needed: hcp create cluster aws \ --name <hosted_cluster_name> \ 1 --node-pool-replicas=<node_pool_replica_count> \ 2 --base-domain <basedomain> \ 3 --pull-secret <path_to_pull_secret> \ 4 --sts-creds <path_to_sts_credential_file> \ 5 --region <region> \ 6 --endpoint-access Private 7 --role-arn <role_name> 8 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the node pool replica count, for example, 3 . 3 Specify your base domain, for example, example.com . 4 Specify the path to your pull secret, for example, /user/name/pullsecret . 5 Specify the path to your AWS STS credentials file, for example, /home/user/sts-creds/sts-creds.json . 6 Specify the AWS region name, for example, us-east-1 . 7 Defines whether a cluster is public or private. 8 Specify the Amazon Resource Name (ARN), for example, arn:aws:iam::820196288204:role/myrole .

Managing AWS infrastructure and IAM permissions for hosted control planes When you use hosted control planes for Red Hat OpenShift Container Platform on Amazon Web Services (AWS), the infrastructure requirements vary based on your setup. Prerequisites AWS infrastructure requirements Identity and Access Management permissions Creating AWS infrastructure and IAM resources separately 1.8.6.13.1. Prerequisites You must configure hosted control planes before you can create hosted control plane clusters. See Configuring hosted control plane clusters on AWS for more information. You must create an AWS Identity and Access Management (IAM) role and AWS Security Token Service (STS) credentials. See Creating an AWS IAM role and STS credentials . 1.8.6.13.2. AWS infrastructure requirements When you use hosted control planes on AWS, the infrastructure requirements fit in the following categories: Prerequired and unmanaged infrastructure for the HyperShift Operator in an arbitrary AWS account Prerequired and unmanaged infrastructure in a hosted cluster AWS account Hosted control planes-managed infrastructure in a management AWS account Hosted control planes-managed infrastructure in a hosted cluster AWS account Kubernetes-managed infrastructure in a hosted cluster AWS account Prerequired means that hosted control planes requires AWS infrastructure to properly work. Unmanaged means that no Operator or controller creates the infrastructure for you. The following sections contain details about the creation of the AWS resources. 1.8.6.13.2.1. Prerequired and unmanaged infrastructure for the HyperShift Operator in an arbitrary AWS account An arbitrary AWS account depends on the provider of the hosted control planes service. In self-managed hosted control planes, the cluster service provider controls the AWS account. The cluster service provider is the administrator who hosts cluster control planes and is responsible for uptime. In managed hosted control planes, the AWS account belongs to Red Hat. In a prerequired and unmanaged infrastructure for the HyperShift Operator, the following infrastructure requirements apply for a management cluster AWS account: One S3 Bucket OpenID Connect (OIDC) Route 53 hosted zones A domain to host private and public entries for hosted clusters 1.8.6.13.2.2. Prerequired and unmanaged infrastructure in a hosted cluster AWS account When your infrastructure is prerequired and unmanaged in a hosted cluster AWS account, the infrastructure requirements for all access modes are as follows: One VPC One DHCP Option Two subnets A private subnet that is an internal data plane subnet A public subnet that enables access to the internet from the data plane One internet gateway One elastic IP One NAT gateway One security group (worker nodes) Two route tables (one private and one public) Two Route 53 hosted zones Enough quota for the following items: One Ingress service load balancer for public hosted clusters One private link endpoint for private hosted clusters Note: For private link networking to work, the endpoint zone in the hosted cluster AWS account must match the zone of the instance that is resolved by the service endpoint in the management cluster AWS account. In AWS, the zone names are aliases, such as us-east-2b , which do not necessarily map to the same zone in different accounts. As a result, for private link to work, the management cluster must have subnets or workers in all zones of its region. 1.8.6.13.2.3. Hosted control planes-managed infrastructure in a management AWS account When your infrastructure is managed by hosted control planes in a management AWS account, the infrastructure requirements differ depending on whether your clusters are public, private, or a combination. For accounts with public clusters, the infrastructure requirements are as follows: Network load balancer: a load balancer Kube API server Kubernetes creates a security group Volumes For etcd (one or three depending on high availability) For OVN-Kube For accounts with private clusters, the infrastructure requirements are as follows: Network load balancer: a load balancer private router Endpoint service (private link) For accounts with public and private clusters, the infrastructure requirements are as follows: Network load balancer: a load balancer public router Network load balancer: a load balancer private router Endpoint service (private link) Volumes: For etcd (one or three depending on high availability) For OVN-Kube 1.8.6.13.2.4. Hosted control planes-managed infrastructure in a hosted cluster AWS account When your infrastructure is managed by hosted control planes in a hosted cluster AWS account, the infrastructure requirements differ depending on whether your clusters are public, private, or a combination. For accounts with public clusters, the infrastructure requirements are as follows: Node pools must have EC2 instances that have Role and RolePolicy defined. For accounts with private clusters, the infrastructure requirements are as follows: One private link endpoint for each availability zone EC2 instances for node pools For accounts with public and private clusters, the infrastructure requirements are as follows: One private link endpoint for each availability zone EC2 instances for node pools 1.8.6.13.2.5. Kubernetes-managed infrastructure in a hosted cluster AWS account When Kubernetes manages your infrastructure in a hosted cluster AWS account, the infrastructure requirements are as follows: A network load balancer for default Ingress An S3 bucket for registry 1.8.6.13.3. Identity and Access Management (IAM) permissions In the context of hosted control planes, the consumer is responsible to create the Amazon Resource Name (ARN) roles. The consumer is an automated process to generate the permissions files. The consumer might be the command line interface or OpenShift Cluster Manager. Hosted control planes tries to enable granularity to honor the principle of least-privilege components, which means that every component uses its own role to operate or create AWS objects, and the roles are limited to what is required for the product to function normally. For an example of how the command line interface can create the ARN roles, see "Creating AWS infrastructure and IAM resources separately". The hosted cluster receives the ARN roles as input and the consumer creates an AWS permission configuration for each component. As a result, the component can authenticate through STS and preconfigured OIDC IDP. The following roles are consumed by some of the components from hosted control planes that run on the control plane and operate on the data plane: controlPlaneOperatorARN imageRegistryARN ingressARN kubeCloudControllerARN nodePoolManagementARN storageARN networkARN The following example shows a reference to the IAM roles from the hosted cluster: The roles that hosted control planes uses are shown in the following examples: ingressARN imageRegistryARN storageARN networkARN kubeCloudControllerARN nodePoolManagementARN controlPlaneOperatorARN 1.8.6.13.4. Creating AWS infrastructure and IAM resources separately By default, the hcp create cluster aws command creates cloud infrastructure with the hosted cluster and applies it. You can create the cloud infrastructure portion separately so that the hcp create cluster aws command can be used only to create the cluster, or render it so that you can modify it before you apply it. To create the cloud infrastructure portion separately, you need to create the AWS infrastructure, create the AWS Identity and Access (IAM) resources, and create the cluster. 1.8.6.13.4.1. Creating the AWS infrastructure To create the AWS infrastructure, you need to create a VPC and other resources for your cluster. You can use the AWS console or an infrastructure automation and provisioning tool. For instructions to use the AWS console, see Create a VPC plus other VPC resources in the AWS Documentation. The VPC must include private and public subnets and resources for external access, such as an NAT gateway and an internet gateway. In addition to the VPC, you need a private hosted zone for the ingress of your cluster. If you are creating clusters that use PrivateLink ( Private or PublicAndPrivate access modes), you need an additional hosted zone for PrivateLink. The following YAML file shows the fields that are required to create the AWS infrastructure for your cluster. Example YAML file --- apiVersion: v1 kind: Namespace metadata: creationTimestamp: null name: clusters spec: {} status: {} --- apiVersion: v1 data: .dockerconfigjson: xxxxxxxxxxx kind: Secret metadata: creationTimestamp: null labels: hypershift.openshift.io/safe-to-delete-with-cluster: "true" name: <pull_secret_name> 1 namespace: clusters --- apiVersion: v1 data: key: xxxxxxxxxxxxxxxxx kind: Secret metadata: creationTimestamp: null labels: hypershift.openshift.io/safe-to-delete-with-cluster: "true" name: <etcd_encryption_key_name> 2 namespace: clusters type: Opaque --- apiVersion: v1 data: id_rsa: xxxxxxxxx id_rsa.pub: xxxxxxxxx kind: Secret metadata: creationTimestamp: null labels: hypershift.openshift.io/safe-to-delete-with-cluster: "true" name: <ssh-key-name> 3 namespace: clusters --- apiVersion: hypershift.openshift.io/v1beta1 kind: HostedCluster metadata: creationTimestamp: null name: <hosted_cluster_name> 4 namespace: clusters spec: autoscaling: {} configuration: {} controllerAvailabilityPolicy: SingleReplica dns: baseDomain: <dns_domain> 5 privateZoneID: xxxxxxxx publicZoneID: xxxxxxxx etcd: managed: storage: persistentVolume: size: 8Gi storageClassName: gp3-csi type: PersistentVolume managementType: Managed fips: false infraID: <infra_id> 6 issuerURL: <issuer_url> 7 networking: clusterNetwork: - cidr: 10.132.0.0/14 machineNetwork: - cidr: 10.0.0.0/16 networkType: OVNKubernetes serviceNetwork: - cidr: 172.31.0.0/16 olmCatalogPlacement: management platform: aws: cloudProviderConfig: subnet: id: <subnet_xxx> 8 vpc: <vpc_xxx> 9 zone: us-west-1b endpointAccess: Public multiArch: false region: us-west-1 rolesRef: controlPlaneOperatorARN: arn:aws:iam::820196288204:role/<infra_id>-control-plane-operator imageRegistryARN: arn:aws:iam::820196288204:role/<infra_id>-openshift-image-registry ingressARN: arn:aws:iam::820196288204:role/<infra_id>-openshift-ingress kubeCloudControllerARN: arn:aws:iam::820196288204:role/<infra_id>-cloud-controller networkARN: arn:aws:iam::820196288204:role/<infra_id>-cloud-network-config-controller nodePoolManagementARN: arn:aws:iam::820196288204:role/<infra_id>-node-pool storageARN: arn:aws:iam::820196288204:role/<infra_id>-aws-ebs-csi-driver-controller type: AWS pullSecret: name: <pull_secret_name> release: image: quay.io/openshift-release-dev/ocp-release:4.16-x86_64 secretEncryption: aescbc: activeKey: name: <etcd_encryption_key_name> type: aescbc services: - service: APIServer servicePublishingStrategy: type: LoadBalancer - service: OAuthServer servicePublishingStrategy: type: Route - service: Konnectivity servicePublishingStrategy: type: Route - service: Ignition servicePublishingStrategy: type: Route - service: OVNSbDb servicePublishingStrategy: type: Route sshKey: name: <ssh_key_name> status: controlPlaneEndpoint: host: "" port: 0 --- apiVersion: hypershift.openshift.io/v1beta1 kind: NodePool metadata: creationTimestamp: null name: <node_pool_name> 10 namespace: clusters spec: arch: amd64 clusterName: <hosted_cluster_name> management: autoRepair: true upgradeType: Replace nodeDrainTimeout: 0s platform: aws: instanceProfile: <instance_profile_name> 11 instanceType: m6i.xlarge rootVolume: size: 120 type: gp3 subnet: id: <subnet_xxx> type: AWS release: image: quay.io/openshift-release-dev/ocp-release:4.16-x86_64 replicas: 2 status: replicas: 0 1 Replace <pull_secret_name> with the name of your pull secret. 2 Replace <etcd_encryption_key_name> with the name of your etcd encryption key. 3 Replace <ssh_key_name> with the name of your SSH key. 4 Replace <hosted_cluster_name> with the name of your hosted cluster. 5 Replace <dns_domain> with your base DNS domain, such as example.com . 6 Replace <infra_id> with the value that identifies the IAM resources that are associated with the hosted cluster. 7 Replace <issuer_url> with your issuer URL, which ends with your infra_id value. For example, https://example-hosted-us-west-1.s3.us-west-1.amazonaws.com/example-hosted-infra-id . 8 Replace <subnet_xxx> with your subnet ID. Both private and public subnets need to be tagged. For public subnets, use kubernetes.io/role/elb=1 . For private subnets, use kubernetes.io/role/internal-elb=1 . 9 Replace <vpc_xxx> with your VPC ID. 10 Replace <node_pool_name> with the name of your NodePool resource. 11 Replace <instance_profile_name> with the name of your AWS instance. 1.8.6.13.4.2. Creating the AWS IAM resources In AWS, you need to create the following IAM resources: One OIDC provider, which is required to enable STS authentication Seven roles, which are separate for every component that interacts with the provider, such as the Kubernetes controller manager, cluster API provider, and registry One instance profile, which is the profile that is assigned to all worker instances of the cluster To create an OIDC provider, follow the steps in Create an OpenID Connect (OIDC) identity provider in IAM in the AWS documentation. To create the roles for each component that interacts with the provider, follow the procedures in Creating IAM roles in the AWS documentation. For more information about the roles, see "Identity and Access Management (IAM) permissions." To create an instance profile, see Using instance profiles in the AWS documentation. 1.8.6.13.4.3. Creating the cluster To create the cluster, enter the following command: hcp create cluster aws \ --infra-id <infra_id> \ 1 --name <hosted_cluster_name> \ 2 --sts-creds <path_to_sts_credential_file> \ 3 --pull-secret <path_to_pull_secret> \ 4 --generate-ssh \ 5 --node-pool-replicas 3 --role-arn <role_name> 6 1 Replace <infra_id> with the same ID that you specified in the create infra aws command. This value identifies the IAM resources that are associated with the hosted cluster. 2 Replace <hosted_cluster_name> with the name of your hosted cluster. 3 Replace <path_to_sts_credential_file> with the same name that you specified in the create infra aws command. 4 Replace <path_to_pull_secret> with the name of the file that contains a valid OpenShift Container Platform pull secret. 5 The --generate-ssh flag is optional, but is good to include in case you need to SSH to your workers. An SSH key is generated for you and is stored as a secret in the same namespace as the hosted cluster. 6 Replace <role_name> with the Amazon Resource Name (ARN), for example, arn:aws:iam::820196288204:role/myrole . Specify the Amazon Resource Name (ARN), for example, arn:aws:iam::820196288204:role/myrole . For more information about ARN roles, see "Identity and Access Management (IAM) permissions". You can also add the --render flag to the command and redirect output to a file where you can edit the resources before you apply them to the cluster. After you run the command, the following resources are applied to your cluster: A namespace A secret with your pull secret A HostedCluster A NodePool Three AWS STS secrets for control plane components One SSH key secret if you specified the --generate-ssh flag. 1.8.6.14. Destroying a hosted cluster on AWS To destroy a hosted cluster and its managed cluster resource on Amazon Web Services (AWS), complete the following steps: Delete the managed cluster resource on multicluster engine operator. Replace <hosted_cluster_name> with the name of your cluster. Run the following command: oc delete managedcluster <hosted_cluster_name> Delete the hosted cluster and its back-end resources by running the following command: hcp destroy cluster aws \ --name <hosted_cluster_name> \ 1 --infra-id <infra_id> \ 2 --role-arn <arn_role> \ 3 --sts-creds <path_to_sts_credential_file> \ 4 --base-domain <basedomain> 5 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the infrastructure name for your hosted cluster. 3 Specify the Amazon Resource Name (ARN), for example, arn:aws:iam::820196288204:role/myrole . 4 Specify the path to your AWS Security Token Service (STS) credentials file, for example, /home/user/sts-creds/sts-creds.json . 5 Specify your base domain, for example, example.com . Note: If your session token for AWS Security Token Service (STS) is expired, retrieve STS credentials in a JSON file named sts-creds.json by running the following command: aws sts get-session-token --output json > sts-creds.json 1.8.7. Configuring hosted control plane clusters on bare metal You can deploy hosted control planes by configuring a cluster to function as a hosting cluster. The hosting cluster is the OpenShift Container Platform cluster where the control planes are hosted. The hosting cluster is also known as the management cluster. Note: The management cluster is not the same thing as the managed cluster. A managed cluster is a cluster that the hub cluster manages. The hosted control planes feature is enabled by default. The multicluster engine operator 2.5 supports only the default local-cluster , which is a hub cluster that is managed, and the hub cluster as the hosting cluster. On Red Hat Advanced Cluster Management 2.10, you can use the managed hub cluster, also known as the local-cluster , as the hosting cluster. A hosted cluster is an OpenShift Container Platform cluster with its API endpoint and control plane that are hosted on the hosting cluster. The hosted cluster includes the control plane and its corresponding data plane. You can use the multicluster engine operator console or the hosted control plane command line interface, hcp , to create a hosted cluster. The hosted cluster is automatically imported as a managed cluster. If you want to disable this automatic import feature, see Disabling the automatic import of hosted clusters into multicluster engine operator . Important: Run the hub cluster and workers on the same platform for hosted control planes. Each hosted cluster must have a cluster-wide unique name. A hosted cluster name cannot be the same as any existing managed cluster in order for multicluster engine operator to manage it. Do not use clusters as a hosted cluster name. A hosted cluster cannot be created in the namespace of a multicluster engine operator managed cluster. To provision hosted control planes on bare metal, you can use the Agent platform. The Agent platform uses the central infrastructure management service to add worker nodes to a hosted cluster. For an introduction to the central infrastructure management service, see Enabling the central infrastructure management service . All bare metal hosts require a manual boot with a Discovery Image ISO that the central infrastructure management provides. You can start the hosts manually or through automation by using Cluster-Baremetal-Operator . After each host starts, it runs an Agent process to discover the host details and complete the installation. An Agent custom resource represents each host. When you create a hosted cluster with the Agent platform, HyperShift installs the Agent Cluster API provider in the hosted control plane namespace. When you scale a replica by the node pool, a machine is created. For every machine, the Cluster API provider finds and installs an Agent that meets the requirements that are specified in the node pool specification. You can monitor the installation of an Agent by checking its status and conditions. When you scale down a node pool, Agents are unbound from the corresponding cluster. Before you can reuse the Agents, you must restart them by using the Discovery image. When you configure storage for hosted control planes, consider the recommended etcd practices. To ensure that you meet the latency requirements, dedicate a fast storage device to all hosted control plane etcd instances that run on each control-plane node. You can use LVM storage to configure a local storage class for hosted etcd pods. For more information, see Recommended etcd practices and Persistent storage using logical volume manager storage in the OpenShift Container Platform documentation. 1.8.7.1. Prerequisites You must have the following prerequisites to configure a hosting cluster: You need the multicluster engine for Kubernetes operator 2.2 and later installed on an OpenShift Container Platform cluster. The multicluster engine operator is automatically installed when you install Red Hat Advanced Cluster Management. You can also install multicluster engine operator without Red Hat Advanced Cluster Management as an Operator from the OpenShift Container Platform OperatorHub. The multicluster engine operator must have at least one managed OpenShift Container Platform cluster. The local-cluster is automatically imported in multicluster engine operator 2.2 and later. See Advanced configuration for more information about the local-cluster . You can check the status of your hub cluster by running the following command: You must add the topology.kubernetes.io/zone label to your bare metal hosts on your management cluster. Otherwise, all of the hosted control plane pods are scheduled on a single node, causing single point of failure. You need to enable central infrastructure management. For more information, see Enabling the central infrastructure management service . You need to install the hosted control plane command line interface . For a hub cluster that has a proxy configuration to reach the hosted cluster API endpoint, add all hosted cluster API endpoints to the noProxy field on the Proxy object. For more information, see Configuring the cluster-wide proxy . 1.8.7.2. Bare metal firewall, port, and service requirements You must meet the firewall, port, and service requirements so that ports can communicate between the management cluster, the control plane, and hosted clusters. Note: Services run on their default ports. However, if you use the NodePort publishing strategy, services run on the port that is assigned by the NodePort service. Use firewall rules, security groups, or other access controls to restrict access to only required sources. Avoid exposing ports publicly unless necessary. For production deployments, use a load balancer to simplify access through a single IP address. A hosted control plane exposes the following services on bare metal: APIServer The APIServer service runs on port 6443 by default and requires ingress access for communication between the control plane components. If you use MetalLB load balancing, allow ingress access to the IP range that is used for load balancer IP addresses. OAuthServer The OAuthServer service runs on port 443 by default when you use the route and ingress to expose the service. If you use the NodePort publishing strategy, use a firewall rule for the OAuthServer service. Konnectivity The Konnectivity service runs on port 443 by default when you use the route and ingress to expose the service. The Konnectivity agent establishes a reverse tunnel to allow the control plane to access the network for the hosted cluster. The agent uses egress to connect to the Konnectivity server. The server is exposed by using either a route on port 443 or a manually assigned NodePort . If the cluster API server address is an internal IP address, allow access from the workload subnets to the IP address on port 6443. If the address is an external IP address, allow egress on port 6443 to that external IP address from the nodes. Ignition The Ignition service runs on port 443 by default when you use the route and ingress to expose the service. If you use the NodePort publishing strategy, use a firewall rule for the Ignition service. You do not need the following services on bare metal: OVNSbDb OIDC 1.8.7.3. Bare metal infrastructure requirements The Agent platform does not create any infrastructure, but it does have the following requirements for infrastructure: Agents: An Agent represents a host that is booted with a discovery image and is ready to be provisioned as an OpenShift Container Platform node. DNS: The API and ingress endpoints must be routable. For additional resources about hosted control planes on bare metal, see the following documentation: To learn about etcd and LVM storage recommendations, see Recommended etcd practices and Persistent storage using logical volume manager storage . To configure hosted control planes on bare metal in disconnected environment, see Configuring hosted control planes in a disconnected environment . To disable the hosted control planes feature or, if you already disabled it and want to manually enable it, see Enabling or disabling the hosted control planes feature . To manage hosted clusters by running Red Hat Ansible Automation Platform jobs, see Configuring Ansible Automation Platform jobs to run on hosted clusters . To deploy the SR-IOV Operator, see Deploying the SR-IOV Operator for hosted control planes . If you want to disable the automatic import feature, see Disabling the automatic import of hosted clusters into multicluster engine operator . 1.8.7.4. Configuring DNS on bare metal The API Server for the hosted cluster is exposed as a NodePort service. A DNS entry must exist for api.USD{HOSTED_CLUSTER_NAME}.USD{BASEDOMAIN} that points to destination where the API Server can be reached. The DNS entry can be as simple as a record that points to one of the nodes in the managed cluster that is running the hosted control plane. The entry can also point to a load balancer that is deployed to redirect incoming traffic to the ingress pods. See the following example DNS configuration: If you are configuring DNS for a disconnected environment on an IPv6 network, see the following example DNS configuration: If you are configuring DNS for a disconnected environment on a dual stack network, be sure to include DNS entries for both IPv4 and IPv6. See the following example DNS configuration: , create a host inventory for hosted control planes on bare metal. 1.8.7.5. Creating a hosted cluster on bare metal You can create a hosted cluster on bare metal or import one. For instructions to import a hosted cluster, see Importing a hosted cluster . Create the hosted control plane namespace by entering the following command: oc create ns <hosted_cluster_namespace>-<hosted_cluster_name> Replace <hosted_cluster_namespace> with your hosted cluster namespace name, for example, clusters . Replace <hosted_cluster_name> with your hosted cluster name. Verify that you have a default storage class configured for your cluster. Otherwise, you might see pending PVCs. Run the following command: hcp create cluster agent \ --name=<hosted_cluster_name> \ 1 --pull-secret=<path_to_pull_secret> \ 2 --agent-namespace=<hosted_control_plane_namespace> \ 3 --base-domain=<basedomain> \ 4 --api-server-address=api.<hosted_cluster_name>.<basedomain> \ 5 --etcd-storage-class=<etcd_storage_class> \ 6 --ssh-key <path_to_ssh_public_key> \ 7 --namespace <hosted_cluster_namespace> \ 8 --control-plane-availability-policy SingleReplica \ --release-image=quay.io/openshift-release-dev/ocp-release:<ocp_release_image> 9 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the path to your pull secret, for example, /user/name/pullsecret . 3 Specify your hosted control plane namespace, for example, clusters-example . Ensure that agents are available in this namespace by using the oc get agent -n <hosted_control_plane_namespace> command. 4 Specify your base domain, for example, krnl.es . 5 The --api-server-address flag defines the IP address that is used for the Kubernetes API communication in the hosted cluster. If you do not set the --api-server-address flag, you must log in to connect to the management cluster. 6 Specify the etcd storage class name, for example, lvm-storageclass . 7 Specify the path to your SSH public key. The default file path is ~/.ssh/id_rsa.pub . 8 Specify your hosted cluster namespace. 9 Specify the supported OpenShift Container Platform version that you want to use, for example, 4.14.0-x86_64 . If you are using a disconnected environment, replace <ocp_release_image> with the digest image. To extract the OpenShift Container Platform release image digest, see Extracting the OpenShift Container Platform release image digest . After a few moments, verify that your hosted control plane pods are up and running by entering the following command: oc -n <hosted_control_plane_namespace> get pods See the following example output: 1.8.7.5.1. Creating a hosted cluster on bare metal by using the console Open the OpenShift Container Platform web console and log in by entering your administrator credentials. For instructions to open the console, see Accessing the web console in the OpenShift Container Platform documentation. In the console header, ensure that All Clusters is selected. Click Infrastructure > Clusters . Click Create cluster > Host inventory > Hosted control plane . The Create cluster page is displayed. On the Create cluster page, follow the prompts to enter details about the cluster, node pools, networking, and automation. Note: As you enter details about the cluster, you might find the following tips useful: If you want to use predefined values to automatically populate fields in the console, you can create a host inventory credential. For more information, see Creating a credential for an on-premises environment . On the Cluster details page, the pull secret is your OpenShift Container Platform pull secret that you use to access OpenShift Container Platform resources. If you selected a host inventory credential, the pull secret is automatically populated. On the Node pools page, the namespace contains the hosts for the node pool. If you created a host inventory by using the console, the console creates a dedicated namespace. On the Networking page, you select an API server publishing strategy. The API server for the hosted cluster can be exposed either by using an existing load balancer or as a service of the NodePort type. A DNS entry must exist for the api.USD{HOSTED_CLUSTER_NAME}.USD{BASEDOMAIN} setting that points to the destination where the API server can be reached. This entry can be a record that points to one of the nodes in the management cluster or a record that points to a load balancer that redirects incoming traffic to the Ingress pods. Review your entries and click Create . The Hosted cluster view is displayed. Monitor the deployment of the hosted cluster in the Hosted cluster view. If you do not see information about the hosted cluster, ensure that All Clusters is selected, then click the cluster name. Wait until the control plane components are ready. This process can take a few minutes. To view the node pool status, scroll to the NodePool section. The process to install the nodes takes about 10 minutes. You can also click Nodes to confirm whether the nodes joined the hosted cluster. 1.8.7.5.2. Creating a hosted cluster on bare metal by using a mirror registry You can use a mirror registry to create a hosted cluster on bare metal by specifying the --image-content-sources flag in the hcp create cluster command. Complete the following steps: Create a YAML file to define Image Content Source Policies (ICSP). See the following example: - mirrors: - brew.registry.redhat.io source: registry.redhat.io - mirrors: - brew.registry.redhat.io source: registry.stage.redhat.io - mirrors: - brew.registry.redhat.io source: registry-proxy.engineering.redhat.com Save the file as icsp.yaml . This file contains your mirror registries. To create a hosted cluster by using your mirror registries, run the following command: hcp create cluster agent \ --name=<hosted_cluster_name> \ 1 --pull-secret=<path_to_pull_secret> \ 2 --agent-namespace=<hosted_control_plane_namespace> \ 3 --base-domain=<basedomain> \ 4 --api-server-address=api.<hosted_cluster_name>.<basedomain> \ 5 --image-content-sources icsp.yaml \ 6 --ssh-key <path_to_ssh_key> \ 7 --namespace <hosted_cluster_namespace> \ 8 --release-image=quay.io/openshift-release-dev/ocp-release:<ocp_release_image> 9 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the path to your pull secret, for example, /user/name/pullsecret . 3 Specify your hosted control plane namespace, for example, clusters-example . Ensure that agents are available in this namespace by using the oc get agent -n <hosted-control-plane-namespace> command. 4 Specify your base domain, for example, krnl.es . 5 The --api-server-address flag defines the IP address that is used for the Kubernetes API communication in the hosted cluster. If you do not set the --api-server-address flag, you must log in to connect to the management cluster. 6 Specify the icsp.yaml file that defines ICSP and your mirror registries. 7 Specify the path to your SSH public key. The default file path is ~/.ssh/id_rsa.pub . 8 Specify your hosted cluster namespace. 9 Specify the supported OpenShift Container Platform version that you want to use, for example, 4.14.0-x86_64 . If you are using a disconnected environment, replace <ocp_release_image> with the digest image. To extract the OpenShift Container Platform release image digest, see Extracting the OpenShift Container Platform release image digest . 1.8.7.5.3.

Verifying hosted cluster creation After the deployment process is complete, you can verify that the hosted cluster was created successfully. Follow these steps a few minutes after you create the hosted cluster. Obtain the kubeconfig for your new hosted cluster by entering the extract command: Use the kubeconfig to view the cluster Operators of the hosted cluster. Enter the following command: See the following example output: You can also view the running pods on your hosted cluster by entering the following command: See the following example output: 1.8.7.7. Scaling the NodePool object for a hosted cluster You can scale up the NodePool object, by adding nodes to your hosted cluster. Scale the NodePool object to two nodes: The Cluster API agent provider randomly picks two agents that are then assigned to the hosted cluster. Those agents go through different states and finally join the hosted cluster as OpenShift Container Platform nodes. The agents pass through states in the following order: binding discovering insufficient installing installing-in-progress added-to-existing-cluster Enter the following command: See the following example output: Enter the following command: See the following example output: Obtain the kubeconfig for your new hosted cluster by entering the extract command: After the agents reach the added-to-existing-cluster state, verify that you can see the OpenShift Container Platform nodes in the hosted cluster by entering the following command: See the following example output: Cluster Operators start to reconcile by adding workloads to the nodes. Enter the following command to verify that two machines were created when you scaled up the NodePool object: See the following example output: The clusterversion reconcile process eventually reaches a point where only Ingress and Console cluster operators are missing. Enter the following command: See the following example output: 1.8.7.7.1. Adding node pools You can create node pools for a hosted cluster by specifying a name, number of replicas, and any additional information, such as an agent label selector. To create a node pool, enter the following information: 1 The --agentLabelSelector is optional. The node pool uses agents with the "size" : "medium" label.

Handling ingress in a hosted cluster on bare metal Every OpenShift Container Platform cluster has a default application Ingress Controller that typically has an external DNS record associated with it. For example, if you create a hosted cluster named example with the base domain krnl.es , you can expect the wildcard domain *.apps.example.krnl.es to be routable. To set up a load balancer and wildcard DNS record for the *.apps domain, perform the following actions on your guest cluster: Deploy MetalLB by creating a YAML file that contains the configuration for the MetalLB Operator: apiVersion: v1 kind: Namespace metadata: name: metallb labels: openshift.io/cluster-monitoring: "true" annotations: workload.openshift.io/allowed: management --- apiVersion: operators.coreos.com/v1 kind: OperatorGroup metadata: name: metallb-operator-operatorgroup namespace: metallb --- apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: name: metallb-operator namespace: metallb spec: channel: "stable" name: metallb-operator source: redhat-operators sourceNamespace: openshift-marketplace Save the file as metallb-operator-config.yaml . Enter the following command to apply the configuration: oc apply -f metallb-operator-config.yaml After the Operator is running, create the MetalLB instance: Create a YAML file that contains the configuration for the MetalLB instance: apiVersion: metallb.io/v1beta1 kind: MetalLB metadata: name: metallb namespace: metallb Save the file as metallb-instance-config.yaml . Create the MetalLB instance by entering this command: oc apply -f metallb-instance-config.yaml Configure the MetalLB Operator by creating two resources: An IPAddressPool resource with a single IP address. This IP address must be on the same subnet as the network that the cluster nodes use. A BGPAdvertisement resource to advertise the load balancer IP addresses that the IPAddressPool resource provides through the BGP protocol. Create a YAML file to contain the configuration: apiVersion: metallb.io/v1beta1 kind: IPAddressPool metadata: name: <ip_address_pool_name> 1 namespace: metallb spec: protocol: layer2 autoAssign: false addresses: - <ingress_ip>-<ingress_ip> 2 --- apiVersion: metallb.io/v1beta1 kind: BGPAdvertisement metadata: name: <bgp_advertisement_name> 3 namespace: metallb spec: ipAddressPools: - <ip_address_pool_name> 4 1 4 Specify the IPAddressPool resource name. 2 Specify the IP address for your environment, for example, 192.168.122.23 . 3 Specify the BGPAdvertisement resource name. Save the file as ipaddresspool-bgpadvertisement-config.yaml . Create the resources by entering the following command: oc apply -f ipaddresspool-bgpadvertisement-config.yaml After creating a service of the LoadBalancer type, MetalLB adds an external IP address for the service. Configure a new load balancer service that routes ingress traffic to the ingress deployment by creating a YAML file named metallb-loadbalancer-service.yaml : kind: Service apiVersion: v1 metadata: annotations: metallb.universe.tf/address-pool: ingress-public-ip name: metallb-ingress namespace: openshift-ingress spec: ports: - name: http protocol: TCP port: 80 targetPort: 80 - name: https protocol: TCP port: 443 targetPort: 443 selector: ingresscontroller.operator.openshift.io/deployment-ingresscontroller: default type: LoadBalancer Save the metallb-loadbalancer-service.yaml file.

Enter the following command: oc --kubeconfig <hosted_cluster_name>.kubeconfig get clusterversion,co See the following example output: + Replace 4.x.y with the supported OpenShift Container Platform version that you want to use, for example, 4.14.0-x86_64 . 1.8.7.8.1. Additional resources For more information about MetalLB, see About MetalLB and the MetalLB Operator in the OpenShift Container Platform documentation. 1.8.7.9. Enabling node auto-scaling for the hosted cluster When you need more capacity in your hosted cluster and spare agents are available, you can enable auto-scaling to install new worker nodes. To enable auto-scaling, enter the following command: Note: In the example, the minimum number of nodes is 2, and the maximum is 5. The maximum number of nodes that you can add might be bound by your platform. For example, if you use the Agent platform, the maximum number of nodes is bound by the number of available agents. Create a workload that requires a new node. Create a YAML file that contains the workload configuration, by using the following example: apiVersion: apps/v1 kind: Deployment metadata: creationTimestamp: null labels: app: reversewords name: reversewords namespace: default spec: replicas: 40 selector: matchLabels: app: reversewords strategy: {} template: metadata: creationTimestamp: null labels: app: reversewords spec: containers: - image: quay.io/mavazque/reversewords:latest name: reversewords resources: requests: memory: 2Gi status: {} Save the file as workload-config.yaml . Apply the YAML by entering the following command: Extract the admin-kubeconfig secret by entering the following command: See the following example output: You can check if new nodes are in the Ready status by entering the following command: To remove the node, delete the workload by entering the following command: Wait for several minutes to pass without requiring the additional capacity. On the Agent platform, the agent is decommissioned and can be reused. You can confirm that the node was removed by entering the following command: 1.8.7.9.1. Disabling node auto-scaling for the hosted cluster To disable node auto-scaling, enter the following command: The command removes "spec.autoScaling" from the YAML file, adds "spec.replicas" , and sets "spec.replicas" to the integer value that you specify. 1.8.7.10. Enabling machine health checks on bare metal You can enable machine health checks on bare metal to repair and replace unhealthy managed cluster nodes automatically. You must have additional agent machines that are ready to install in the managed cluster. Consider the following limitations before enabling machine health checks: You cannot modify the MachineHealthCheck object. Machine health checks replace nodes only when at least two nodes stay in the False or Unknown status for more than 8 minutes. After you enable machine health checks for the managed cluster nodes, the MachineHealthCheck object is created in your hosted cluster. To enable machine health checks in your hosted cluster, modify the NodePool resource. Complete the following steps: Verify that the spec.nodeDrainTimeout value in your NodePool resource is greater than 0s . Replace <hosted_cluster_namespace> with the name of your hosted cluster namespace and <nodepool_name> with the node pool name. Run the following command: oc get nodepool -n <hosted_cluster_namespace> <nodepool_name> -o yaml | grep nodeDrainTimeout See the following example output: If the spec.nodeDrainTimeout value is not greater than 0s , modify the value by running the following command: oc patch nodepool -n <hosted_cluster_namespace> <nodepool_name> -p '{"spec":{"nodeDrainTimeout": "30m"}}' --type=merge Enable machine health checks by setting the spec.management.autoRepair field to true in the NodePool resource. Run the following command: oc patch nodepool -n <hosted_cluster_namespace> <nodepool_name> -p '{"spec": {"management": {"autoRepair":true}}}' --type=merge Verify that the NodePool resource is updated with the autoRepair: true value by running the following command: oc get nodepool -n <hosted_cluster_namespace> <nodepool_name> -o yaml | grep autoRepair 1.8.7.10.1. Disabling machine health checks on bare metal To disable machine health checks for the managed cluster nodes, modify the NodePool resource. Complete the following steps: Disable machine health checks by setting the spec.management.autoRepair field to false in the NodePool resource. Run the following command: oc patch nodepool -n <hosted_cluster_namespace> <nodepool_name> -p '{"spec": {"management": {"autoRepair":false}}}' --type=merge Verify that the NodePool resource is updated with the autoRepair: false value by running the following command: oc get nodepool -n <hosted_cluster_namespace> <nodepool_name> -o yaml | grep autoRepair 1.8.7.10.1.1. Additional resources For more information about machine health checks, see Deploying machine health checks . 1.8.7.11. Destroying a hosted cluster on bare metal You can use the console to destroy bare metal hosted clusters. Complete the following steps to destroy a hosted cluster on bare metal: In the console, navigate to Infrastructure > Clusters . On the Clusters page, select the cluster that you want to destroy. In the Actions menu, select Destroy clusters to remove the cluster. 1.8.7.11.1. Destroying a hosted cluster on bare metal by using the command line To destroy a hosted cluster and its managed cluster resource, complete the following step: Delete the hosted cluster and its back-end resources by running the following command: Replace <cluster_name> with the name of your cluster. 1.8.8. Configuring hosted control plane clusters using non bare metal agent machines (Technology Preview) You can deploy hosted control planes by configuring a cluster to function as a hosting cluster. The hosting cluster is the OpenShift Container Platform cluster where the control planes are hosted. The hosting cluster is also known as the management cluster. Note: The management cluster is not the same thing as the managed cluster. A managed cluster is a cluster that the hub cluster manages. The hosted control planes feature is enabled by default. The multicluster engine operator 2.5 supports only the default local-cluster , which is a hub cluster that is managed, and the hub cluster as the hosting cluster. On Red Hat Advanced Cluster Management 2.10, you can use the managed hub cluster, also known as the local-cluster , as the hosting cluster. A hosted cluster is an OpenShift Container Platform cluster with its API endpoint and control plane that are hosted on the hosting cluster. The hosted cluster includes the control plane and its corresponding data plane. You can use the multicluster engine operator console or the hosted control plane command line interface, hcp , to create a hosted cluster. The hosted cluster is automatically imported as a managed cluster. If you want to disable this automatic import feature, see Disabling the automatic import of hosted clusters into multicluster engine operator . Important: Each hosted cluster must have a cluster-wide unique name. A hosted cluster name cannot be the same as any existing managed cluster in order for multicluster engine operator to manage it. Do not use clusters as a hosted cluster name. Run the hub cluster and workers on the same platform for hosted control planes. A hosted cluster cannot be created in the namespace of a multicluster engine operator managed cluster. You can add agent machines as a worker node to a hosted cluster by using the Agent platform. Agent machine represents a host booted with a Discovery Image and ready to be provisioned as an OpenShift Container Platform node. The Agent platform is part of the central infrastructure management service. For more information, see Enabling the central infrastructure management service . All hosts that are not bare metal require a manual boot with a Discovery Image ISO that the central infrastructure management provides. When you create a hosted cluster with the Agent platform, HyperShift installs the Agent Cluster API provider in the hosted control plane namespace. When you scale up the node pool, a machine is created for every replica. For every machine, the Cluster API provider finds and installs an Agent that is approved, is passing validations, is not currently in use, and meets the requirements that are specified in the node pool specification. You can monitor the installation of an Agent by checking its status and conditions. When you scale down a node pool, Agents are unbound from the corresponding cluster. Before you can reuse the Agents, you must restart them by using the Discovery image. When you configure storage for hosted control planes, consider the recommended etcd practices. To ensure that you meet the latency requirements, dedicate a fast storage device to all hosted control plane etcd instances that run on each control-plane node. You can use LVM storage to configure a local storage class for hosted etcd pods. For more information, see Recommended etcd practices and Persistent storage using logical volume manager storage in the OpenShift Container Platform documentation. 1.8.8.1. Prerequisites You must have the following prerequisites to configure a hosting cluster: You need the multicluster engine for Kubernetes operator 2.5 and later installed on an OpenShift Container Platform cluster. The multicluster engine operator is automatically installed when you install Red Hat Advanced Cluster Management. You can also install multicluster engine operator without Red Hat Advanced Cluster Management as an Operator from the OpenShift Container Platform OperatorHub. The multicluster engine operator must have at least one managed OpenShift Container Platform cluster. The local-cluster is automatically imported. See Advanced configuration for more information about the local-cluster . You can check the status of your hub cluster by running the following command: You need to enable central infrastructure management. For more information, see Enabling the central infrastructure management service . You need to install the hosted control plane command line interface . 1.8.8.2. Firewall and port requirements for non bare metal agent machines Ensure that you meet the firewall and port requirements so that ports can communicate between the management cluster, the control plane, and hosted clusters: The kube-apiserver service runs on port 6443 by default and requires ingress access for communication between the control plane components. If you use the NodePort publishing strategy, ensure that the node port that is assigned to the kube-apiserver service is exposed. If you use MetalLB load balancing, allow ingress access to the IP range that is used for load balancer IP addresses. If you use the NodePort publishing strategy, use a firewall rule for the ignition-server and Oauth-server settings. The konnectivity agent, which establishes a reverse tunnel to allow bi-directional communication on the hosted cluster, requires egress access to the cluster API server address on port 6443. With that egress access, the agent can reach the kube-apiserver service. If the cluster API server address is an internal IP address, allow access from the workload subnets to the IP address on port 6443. If the address is an external IP address, allow egress on port 6443 to that external IP address from the nodes. If you change the default port of 6443, adjust the rules to reflect that change. Ensure that you open any ports that are required by the workloads that run in the clusters. Use firewall rules, security groups, or other access controls to restrict access to only required sources. Avoid exposing ports publicly unless necessary. For production deployments, use a load balancer to simplify access through a single IP address. 1.8.8.3. Infrastructure requirements for non bare metal agent machines The Agent platform does not create any infrastructure, but it does have the following requirements for infrastructure: Agents: An Agent represents a host that is booted with a discovery image and is ready to be provisioned as an OpenShift Container Platform node. DNS: The API and ingress endpoints must be routable. 1.8.8.4. Configuring DNS on non bare metal agent machines The API Server for the hosted cluster is exposed as a NodePort service. A DNS entry must exist for api.<hosted-cluster-name>.<basedomain> that points to destination where the API Server can be reached. The DNS entry can be as simple as a record that points to one of the nodes in the managed cluster that is running the hosted control plane. The entry can also point to a load balancer that is deployed to redirect incoming traffic to the ingress pods. See the following example DNS configuration: If you are configuring DNS for a disconnected environment on an IPv6 network, see the following example DNS configuration: If you are configuring DNS for a disconnected environment on a dual stack network, be sure to include DNS entries for both IPv4 and IPv6. See the following example DNS configuration: 1.8.8.5. Creating a hosted cluster on non bare metal agent machines You can create a hosted cluster or import one. For instructions to import a hosted cluster, see Importing a hosted cluster . Create the hosted control plane namespace by entering the following command: Replace <hosted-cluster-namespace> with your hosted cluster namespace name, for example, clusters . Replace <hosted-cluster-name> with your hosted cluster name. Verify that you have a default storage class configured for your cluster. Otherwise, you might end up with pending PVCs. Enter the following commands, replacing any example variables with your information: 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the path to your pull secret, for example, /user/name/pullsecret . 3 Specify your hosted control plane namespace, for example, clusters-example . Ensure that agents are available in this namespace by using the oc get agent -n <hosted-control-plane-namespace> command. 4 Specify your base domain, for example, krnl.es . 5 The --api-server-address flag defines the IP address that is used for the Kubernetes API communication in the hosted cluster. If you do not set the --api-server-address flag, you must log in to connect to the management cluster. 6 Specify the etcd storage class name, for example, lvm-storageclass . 7 Specify the path to your SSH public key. The default file path is ~/.ssh/id_rsa.pub . 8 Specify your hosted cluster namespace. 9 Specify the supported OpenShift Container Platform version that you want to use, for example, 4.14.0-x86_64 . After a few moments, verify that your hosted control plane pods are up and running by entering the following command: See the following example output: 1.8.8.5.1. Creating a hosted cluster on non bare metal agent machines by using the console Open the OpenShift Container Platform web console and log in by entering your administrator credentials. For instructions to open the console, see Accessing the web console in the OpenShift Container Platform documentation. In the console header, ensure that All Clusters is selected. Click Infrastructure > Clusters . Click Create cluster Host inventory > Hosted control plane . The Create cluster page is displayed. On the Create cluster page, follow the prompts to enter details about the cluster, node pools, networking, and automation. Note: As you enter details about the cluster, you might find the following tips useful: If you want to use predefined values to automatically populate fields in the console, you can create a host inventory credential. For more information, see Creating a credential for an on-premises environment . On the Cluster details page, the pull secret is your OpenShift Container Platform pull secret that you use to access OpenShift Container Platform resources. If you selected a host inventory credential, the pull secret is automatically populated. On the Node pools page, the namespace contains the hosts for the node pool. If you created a host inventory by using the console, the console creates a dedicated namespace. On the Networking page, you select an API server publishing strategy. The API server for the hosted cluster can be exposed either by using an existing load balancer or as a service of the NodePort type. A DNS entry must exist for the api.USD{HOSTED_CLUSTER_NAME}.USD{BASEDOMAIN} setting that points to the destination where the API server can be reached. This entry can be a record that points to one of the nodes in the management cluster or a record that points to a load balancer that redirects incoming traffic to the Ingress pods. Review your entries and click Create . The Hosted cluster view is displayed. Monitor the deployment of the hosted cluster in the Hosted cluster view. If you do not see information about the hosted cluster, ensure that All Clusters is selected, and click the cluster name. Wait until the control plane components are ready. This process can take a few minutes. To view the node pool status, scroll to the NodePool section. The process to install the nodes takes about 10 minutes. You can also click Nodes to confirm whether the nodes joined the hosted cluster. 1.8.8.5.2.

Verifying hosted cluster creation After the deployment process is complete, you can verify that the hosted cluster was created successfully. Follow these steps a few minutes after you create the hosted cluster. Obtain the kubeconfig for your new hosted cluster by entering the extract command: Use the kubeconfig to view the cluster Operators of the hosted cluster. Enter the following command: See the following example output: You can also view the running pods on your hosted cluster by entering the following command: See the following example output: 1.8.8.7. Scaling the NodePool object for a hosted cluster You add nodes to your hosted cluster by scaling the NodePool object. Scale the NodePool object to two nodes: The Cluster API agent provider randomly picks two agents that are then assigned to the hosted cluster. Those agents go through different states and finally join the hosted cluster as OpenShift Container Platform nodes. The agents pass through states in the following order: binding discovering insufficient installing installing-in-progress added-to-existing-cluster Enter the following command: See the following example output: Enter the following command: See the following example output: Obtain the kubeconfig for your new hosted cluster by entering the extract command: After the agents reach the added-to-existing-cluster state, verify that you can see the OpenShift Container Platform nodes in the hosted cluster by entering the following command: See the following example output: Cluster Operators start to reconcile by adding workloads to the nodes. Enter the following command to verify that two machines were created when you scaled up the NodePool object: See the following example output: The clusterversion reconcile process eventually reaches a point where only Ingress and Console cluster operators are missing. Enter the following command: See the following example output: 1.8.8.7.1. Adding node pools You can create node pools for a hosted cluster by specifying a name, number of replicas, and any additional information, such as an agent label selector. To create a node pool, enter the following information: 1 The --agentLabelSelector is optional. The node pool uses agents with the "size" : "medium" label. Check the status of the node pool by listing nodepool resources in the clusters namespace: Extract the admin-kubeconfig secret by entering the following command: See the following example output: After some time, you can check the status of the node pool by entering the following command: Verify that the number of available node pools match with the number of expected node pools by entering this command: 1.8.8.7.2.

Configuring the hosting cluster on a 64-bit x86 OpenShift Container Platform cluster to create hosted control planes for IBM Power compute nodes (Technology Preview) Technology Preview: Configuring the hosting cluster on 64-bit x86 bare metal for IBM Power ( ppc64le ) compute nodes has limited support. You can deploy hosted control planes by configuring a cluster to function as a hosting cluster. The hosting cluster is the OpenShift Container Platform cluster where the control planes are hosted. The hosting cluster is also known as the management cluster. Note: The management cluster is not the managed cluster. A managed cluster is a cluster that the hub cluster manages. The multicluster engine operator 2.5 supports only the default local-cluster , which is a hub cluster that is managed, and the hub cluster as the hosting cluster. Important: To provision hosted control planes on bare metal, you can use the Agent platform. The Agent platform uses the central infrastructure management service to add worker nodes to a hosted cluster. For an introduction to the central infrastructure management service, see Creating a host inventory . Each IBM Power system host must be started with a Discovery Image that the central infrastructure management provides. After each host starts, it runs an Agent process to discover the details of the host and completes the installation. An Agent custom resource represents each host. When you create a hosted cluster with the Agent platform, HyperShift installs the Agent Cluster API provider in the hosted control plane namespace. When you scale up a node pool, a machine is created. The Cluster API provider finds an Agent that is approved, is passing validations, is not currently in use, and meets the requirements that are specified in the node pool specification. You can monitor the installation of an Agent by checking its status and conditions. When you scale down a node pool, Agents are unbound from the corresponding cluster. Before you can reuse the clusters, you must restart them by using the Discovery image to update the number of nodes. 1.8.9.1. Prerequisites You must have the following prerequisites to configure a hosting cluster: multicluster engine for Kubernetes operator 2.5 and later installed on an OpenShift Container Platform cluster. The multicluster engine operator is automatically installed when you install Red Hat Advanced Cluster Management. You can also install multicluster engine operator without Red Hat Advanced Cluster Management as an Operator from the OpenShift Container Platform OperatorHub. The multicluster engine operator must have at least one managed OpenShift Container Platform cluster. The local-cluster is automatically imported in multicluster engine operator 2.5 and later. See Advanced configuration for more information about the local-cluster . You can check the status of your hub cluster by running the following command: oc get managedclusters local-cluster You need a hosting cluster with at least 3 worker nodes to run the HyperShift Operator. You need to enable the central infrastructure management service. For more information, see Enabling the central infrastructure management service . You need to install the hosted control plane command line interface. See Installing the hosted control plane command line interface . 1.8.9.2. IBM Power infrastructure requirements The Agent platform does not create any infrastructure, but requires the following for infrastructure: Agents: An Agent represents a host that is booted with a discovery image and is ready to be provisioned as an OpenShift Container Platform node. DNS: The API and ingress endpoints must be routable. 1.8.9.3. IBM Power configuration documentation After you meet the prerequisites, see the following topics to configure hosted control planes on bare metal: Adding agents to the InfraEnv resource Configuring DNS for hosted control planes on IBM Power Creating a hosted cluster on bare metal Creating an InfraEnv resource for hosted control planes on 64-bit x86 bare metal for IBM Power compute nodes Scaling the NodePool object for a hosted cluster on IBM Power . 1.8.9.4. Adding agents to the InfraEnv resource You can add agents by manually configuring the machine to start with the live ISO. Download the live ISO and use it to start a host (bare metal or VM). The URL for the live ISO can be found in the InfraEnv resource, in the status.isoDownloadURL field. At startup, the host communicates with the Assisted Service and registers as an agent in the same namespace as the InfraEnv resource. To list the agents and some of their properties, enter the following command: See the following example output: After each agent is created, you can optionally set its installation_disk_id and hostname in the specification and approve the agent by entering the following commands: To verify that the agents are approved for use, enter the following command and check the output: See the following example output: 1.8.9.5. Configuring DNS for hosted control planes on IBM Power The API server for the hosted cluster is exposed. A DNS entry must exist for the api.<hosted-cluster-name>.<base-domain> entry that points to the destination where the API server is reachable. The DNS entry can be as simple as a record that points to one of the nodes in the managed cluster that is running the hosted control plane. The entry can also point to a load balancer that is deployed to redirect incoming traffic to the ingress pods. See the following example of DNS configuration: USD cat /var/named/<example.krnl.es.zone> See the following example output: USD TTL 900 @ IN SOA bastion.example.krnl.es.com. hostmaster.example.krnl.es.com.

For IBM Power, add IP addresses that correspond to the IP address of the agent. compute-0 IN A 1xx.2x.2xx.1yy compute-1 IN A 1xx.2x.2xx.1yy 1.8.9.6. Creating an InfraEnv resource for hosted control planes on 64-bit x86 bare metal for IBM Power compute nodes An InfraEnv is a environment where hosts that are starting the live ISO can join as agents. In this case, the agents are created in the same namespace as your hosted control plane. To create an InfraEnv resource, complete the following steps: Create a YAML file to contain the configuration. See the following example: apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv metadata: name: <hosted-cluster-name> namespace: <hosted-control-plane-namespace> spec: cpuArchitecture: ppc64le pullSecretRef: name: pull-secret sshAuthorizedKey: <ssh-public-key> Save the file as infraenv-config.yaml . Apply the configuration by entering the following command: To fetch the URL to download the live ISO, which allows IBM Power machines to join as agents, enter the following command: 1.8.9.7. Scaling the NodePool object for a hosted cluster on IBM Power The NodePool object is created when you create a hosted cluster. By scaling the NodePool object, you can add more compute nodes to the hosted control plane. Run the following command to scale the NodePool object to two nodes: oc -n <clusters_namespace> scale nodepool <nodepool_name> --replicas 2 The Cluster API agent provider randomly picks two agents that are then assigned to the hosted cluster. Those agents go through different states and finally join the hosted cluster as OpenShift Container Platform nodes. The agents pass through the transition phases in the following order: binding discovering insufficient installing installing-in-progress added-to-existing-cluster Run the following command to see the status of a specific scaled agent: oc -n <hosted_control_plane_namespace> get agent -o jsonpath='{range .items[*]}BMH: {@.metadata.labels.agent-install\.openshift\.io/bmh} Agent: {@.metadata.name} State: {@.status.debugInfo.state}{"\n"}{end}' See the following output: BMH: Agent: 50c23cda-cedc-9bbd-bcf1-9b3a5c75804d State: known-unbound BMH: Agent: 5e498cd3-542c-e54f-0c58-ed43e28b568a State: insufficient Run the following command to see the transition phases: oc -n <hosted_control_plane_namespace> get agent See the following output: NAME CLUSTER APPROVED ROLE STAGE 50c23cda-cedc-9bbd-bcf1-9b3a5c75804d hosted-forwarder true auto-assign 5e498cd3-542c-e54f-0c58-ed43e28b568a true auto-assign da503cf1-a347-44f2-875c-4960ddb04091 hosted-forwarder true auto-assign Run the following command to generate the kubeconfig file to access the hosted cluster: hcp create kubeconfig --namespace <clusters_namespace> --name <hosted_cluster_namespace> > <hosted_cluster_name>.kubeconfig After the agents reach the added-to-existing-cluster state, verify that you can see the OpenShift Container Platform nodes by entering the following command: oc --kubeconfig <hosted_cluster_name>.kubeconfig get nodes See the following output: NAME STATUS ROLES AGE VERSION worker-zvm-0.hostedn.example.com Ready worker 5m41s v1.24.0+3882f8f worker-zvm-1.hostedn.example.com Ready worker 6m3s v1.24.0+3882f8f Enter the following command to verify that two machines were created when you scaled up the NodePool object: oc -n <hosted_control_plane_namespace> get machine.cluster.x-k8s.io See the following output: NAME CLUSTER NODENAME PROVIDERID PHASE AGE VERSION hosted-forwarder-79558597ff-5tbqp hosted-forwarder-crqq5 worker-zvm-0.hostedn.example.com agent://50c23cda-cedc-9bbd-bcf1-9b3a5c75804d Running 41h 4.15.0 hosted-forwarder-79558597ff-lfjfk hosted-forwarder-crqq5 worker-zvm-1.hostedn.example.com agent://5e498cd3-542c-e54f-0c58-ed43e28b568a Running 41h 4.15.0 Run the following command to check the cluster version and cluster operator status: oc --kubeconfig <hosted_cluster_name>.kubeconfig get clusterversion See the following output: NAME VERSION AVAILABLE PROGRESSING SINCE STATUS clusterversion.config.openshift.io/version 4.15.0 True False 40h Cluster version is 4.15.0 Run the following command to check the cluster operator status: oc --kubeconfig <hosted_cluster_name>.kubeconfig get clusteroperators For each component of your cluster, the output shows the following cluster operator statuses: NAME , VERSION , AVAILABLE , PROGRESSING , DEGRADED , SINCE , and MESSAGE . For an output example, see the Initial Operator configuration section in the OpenShift Container Platform documentation. 1.8.9.7.1. Additional resources To scale down the data plane to zero, see Scaling down the data plane to zero . 1.8.10. Configuring the hosting cluster on x86 bare metal for IBM Z compute nodes (Technology Preview) Technology Preview: Configuring the hosting cluster on x86 bare metal for IBM Z ( s390x ) compute nodes is in a Technology Preview status with limited support. You can deploy hosted control planes by configuring a cluster to function as a hosting cluster. The hosting cluster is the OpenShift Container Platform cluster where the control planes are hosted. The hosting cluster is also known as the management cluster. Note: The management cluster is not the managed cluster. A managed cluster is a cluster that the hub cluster manages. You can convert a managed cluster to a hosting cluster by using the hypershift add-on to deploy the HyperShift Operator on that cluster. Then, you can start to create the hosted cluster. The multicluster engine operator 2.5 supports only the default local-cluster , which is a hub cluster that is managed, and the hub cluster as the hosting cluster. Important: To provision hosted control planes on bare metal, you can use the Agent platform. The Agent platform uses the central infrastructure management service to add worker nodes to a hosted cluster. For an introduction to the central infrastructure management service, see Kube API - Getting Started Guide . Each IBM Z system host must be started with the PXE images provided by the central infrastructure management. After each host starts, it runs an Agent process to discover the details of the host and completes the installation. An Agent custom resource represents each host. When you create a hosted cluster with the Agent platform, HyperShift Operator installs the Agent Cluster API provider in the hosted control plane namespace. When you scale up a node pool, a machine is created. The Cluster API provider finds an Agent that is approved, is passing validations, is not currently in use, and meets the requirements that are specified in the node pool specification. You can monitor the installation of an Agent by checking its status and conditions. When you scale down a node pool, Agents are unbound from the corresponding cluster. Before you reuse the clusters, you must boot the clusters by using the PXE image to update the number of nodes. 1.8.10.1. Prerequisites multicluster engine for Kubernetes operator version 2.5 or later must be installed on an OpenShift Container Platform cluster. The multicluster engine operator is installed automatically when you install Red Hat Advanced Cluster Management. You can also install multicluster engine operator without Red Hat Advanced Cluster Management as an Operator from the OpenShift Container Platform OperatorHub. The multicluster engine operator must have at least one managed OpenShift Container Platform cluster. The local-cluster is automatically imported in multicluster engine operator 2.5 and later. See Advanced configuration for more information about the local-cluster . You can check the status of your hub cluster by running the following command: oc get managedclusters local-cluster You need a hosting cluster with at least three worker nodes to run the HyperShift Operator. You need to enable the central infrastructure management service. For more information, see Enabling the central infrastructure management service . You need to install the hosted control plane command line interface. See Installing the hosted control plane command line interface . 1.8.10.2. IBM Z infrastructure requirements The Agent platform does not create any infrastructure, but requires the following for infrastructure: Agents: An Agent represents a host that is booted with a discovery image, or PXE image and is ready to be provisioned as an OpenShift Container Platform node. DNS: The API and Ingress endpoints must be routable. The hosted control planes feature is enabled by default. If you disabled the feature and want to manually enable it, or if you need to disable the feature, see Enabling or disabling the hosted control planes feature . 1.8.10.3. IBM Z configuration documentation After you meet the prerequisites, see the following topics to configure hosted control planes on bare metal: Configuring DNS for hosted control planes with IBM Z Creating a hosted cluster on bare metal Creating an InfraEnv resource for hosted control planes on 64-bit x86 bare metal for IBM Z compute nodes Adding IBM Z agents to the InfraEnv resource (Technology Preview) Scaling the NodePool object for a hosted cluster on IBM Z 1.8.10.4. Adding IBM Z agents to the InfraEnv resource (Technology Preview) To attach compute nodes to a hosted control plane, create agents that help you to scale the node pool. Adding agents in an IBM Z environment requires additional steps, which are described in detail in this section. Note: Unless stated otherwise, these procedures apply to both z/VM and RHEL KVM installations on IBM Z and IBM LinuxONE. 1.8.10.4.1. Adding IBM Z KVM as agents For IBM Z with KVM, run the following command to start your IBM Z environment with the downloaded PXE images from the InfraEnv resource. After the Agents are created, the host communicates with the Assisted Service and registers in the same namespace as the InfraEnv resource on the management cluster. virt-install \ --name "<vm_name>" \ 1 --autostart \ --ram=16384 \ --cpu host \ --vcpus=4 \ --location "<path_to_kernel_initrd_image>,kernel=kernel.img,initrd=initrd.img" \ 2 --disk <qcow_image_path> \ 3 --network network:macvtap-net,mac=<mac_address> \ 4 --graphics none \ --noautoconsole \ --wait=-1 --extra-args "rd.neednet=1 nameserver=<nameserver> coreos.live.rootfs_url=http://<http_server>/rootfs.img random.trust_cpu=on rd.luks.options=discard ignition.firstboot ignition.platform.id=metal console=tty1 console=ttyS1,115200n8 coreos.inst.persistent-kargs=console=tty1 console=ttyS1,115200n8" 5 1 Specify the name of the virtual machine. 2 Specify the location of the kernel_initrd_image file. 3 Specify the disk image path. 4 Specify the Mac address. 5 Specify the server name of the agents. For ISO boot, download ISO from the InfraEnv resource and boot the nodes by running the following command: virt-install \ --name "<vm_name>" \ 1 --autostart \ --memory=16384 \ --cpu host \ --vcpus=4 \ --network network:macvtap-net,mac=<mac_address> \ 2 --cdrom "<path_to_image.iso>" \ 3 --disk <qcow_image_path> \ --graphics none \ --noautoconsole \ --os-variant <os_version> \ 4 --wait=-1 1 Specify the name of the virtual machine. 2 Specify the Mac address. 3 Specify the location of the image.iso file. 4 Specify the pperating system version that you are using. 1.8.10.4.2. Adding IBM Z LPAR as agents With OpenShift Container Platform 4.16, you can add the Logical Partition (LPAR) on IBM Z or IBM LinuxONE as a compute node to a hosted control plane. Create a boot parameter file for the agents. Example parameter file rd.neednet=1 cio_ignore=all,!condev \ console=ttysclp0 \ ignition.firstboot ignition.platform.id=metal coreos.live.rootfs_url=http://<http_server>/rhcos-<version>-live-rootfs.<architecture>.img \ 1 coreos.inst.persistent-kargs=console=ttysclp0 ip=<ip>::<gateway>:<netmask>:<hostname>::none nameserver=<dns> \ 2 rd.znet=qeth,<network_adaptor_range>,layer2=1 rd.<disk_type>=<adapter> \ 3 zfcp.allow_lun_scan=0 ai.ip_cfg_override=1 \ 4 random.trust_cpu=on rd.luks.options=discard 1 For the coreos.live.rootfs_url artifact, specify the matching rootfs artifact for the kernel and initramfs that you are starting. Only HTTP and HTTPS protocols are supported. 2 For the ip parameter, manually assign the IP address, as described in Installing a cluster with z/VM on IBM Z and IBM LinuxONE . 3 For installations on DASD-type disks, use rd.dasd to specify the DASD where Red Hat Enterprise Linux CoreOS (RHCOS) is to be installed. For installations on FCP-type disks, use rd.zfcp=<adapter>,<wwpn>,<lun> to specify the FCP disk where RHCOS is to be installed. 4 Specify this parameter when you use an Open Systems Adapter (OSA) or HiperSockets. Generate the .ins and initrd.img.addrsize files. The .ins file includes installation data and is on the FTP server. You can access the file from the HMC system. The .ins file contains details such as mapping of the location of installation data on the disk or FTP server, the memory locations where the data is to be copied. Note : In OpenShift Container Platform 4.16, the .ins file and initrd.img.addrsize are not automatically generated as part of boot-artifacts from the installer. You must manually generate these files. Run the following commands to get the size of the kernel and initrd : KERNEL_IMG_PATH='./kernel.img' INITRD_IMG_PATH='./initrd.img' CMDLINE_PATH='./generic.prm' kernel_size=USD(stat -c%s USDKERNEL_IMG_PATH ) initrd_size=USD(stat -c%s USDINITRD_IMG_PATH) Round the kernel size up to the MiB boundary. This value is the starting address of initrd.img . offset=USD(( (kernel_size + 1048575) / 1048576 * 1048576 )) Create the kernel binary patch file that contains the initrd address and size by running the following commands: INITRD_IMG_NAME=USD(echo USDINITRD_IMG_PATH | rev | cut -d '/' -f 1 | rev) KERNEL_OFFSET=0x00000000 KERNEL_CMDLINE_OFFSET=0x00010480 INITRD_ADDR_SIZE_OFFSET=0x00010408 OFFSET_HEX=USD(printf '0x%08x\n' USDoffset) Convert the address and size to binary format by running the following commands: printf "USD(printf '%016x\n' USDinitrd_size)" | xxd -r -p > temp_size.bin Merge the address and size binaries by running the following command: cat temp_address.bin temp_size.bin > "USDINITRD_IMG_NAME.addrsize" Clean up temporary files by running the following command: rm -rf temp_address.bin temp_size.bin Create the .ins file. The file is based on the paths of the kernel.img , initrd.img , initrd.img.addrsize , and cmdline files and the memory locations where the data is to be copied. USDKERNEL_IMG_PATH USDKERNEL_OFFSET USDINITRD_IMG_PATH USDOFFSET_HEX USDINITRD_IMG_NAME.addrsize USDINITRD_ADDR_SIZE_OFFSET USDCMDLINE_PATH USDKERNEL_CMDLINE_OFFSET Transfer the initrd , kernel , generic.ins , and initrd.img.addrsize parameter files to the file server. For more information about how to transfer the files with FTP and boot, see Installing in an LPAR . Start the machine. Repeat the procedure for all other machines in the cluster. 1.8.10.4.3. Adding IBM z/VM as agents If you want to use a static IP for z/VM guest, you must configure the NMStateConfig attribute for the z/VM agent so that the IP parameter persists in the second start. Complete the following steps to start your IBM Z environment with the downloaded PXE images from the InfraEnv resource. After the Agents are created, the host communicates with the Assisted Service and registers in the same namespace as the InfraEnv resource on the management cluster. Update the parameter file to add the rootfs_url , network_adaptor and disk_type values. Example parameter file rd.neednet=1 cio_ignore=all,!condev \ console=ttysclp0 \ ignition.firstboot ignition.platform.id=metal \ coreos.live.rootfs_url=http://<http_server>/rhcos-<version>-live-rootfs.<architecture>.img \ 1 coreos.inst.persistent-kargs=console=ttysclp0 ip=<ip>::<gateway>:<netmask>:<hostname>::none nameserver=<dns> \ 2 rd.znet=qeth,<network_adaptor_range>,layer2=1 rd.<disk_type>=<adapter> \ 3 zfcp.allow_lun_scan=0 ai.ip_cfg_override=1 \ 4 1 For the coreos.live.rootfs_url artifact, specify the matching rootfs artifact for the kernel and initramfs that you are starting. Only HTTP and HTTPS protocols are supported. 2 For the ip parameter, manually assign the IP address, as described in Installing a cluster with z/VM on IBM Z and IBM LinuxONE . 3 For installations on DASD-type disks, use rd.dasd to specify the DASD where Red Hat Enterprise Linux CoreOS (RHCOS) is to be installed. For installations on FCP-type disks, use rd.zfcp=<adapter>,<wwpn>,<lun> to specify the FCP disk where RHCOS is to be installed. 4 Specify this parameter when you use an Open Systems Adapter (OSA) or HiperSockets. Move initrd , kernel images, and the parameter file to the guest VM by running the following commands: vmur pun -r -u -N kernel.img USDINSTALLERKERNELLOCATION/<image name> vmur pun -r -u -N generic.parm USDPARMFILELOCATION/paramfilename vmur pun -r -u -N initrd.img USDINSTALLERINITRAMFSLOCATION/<image name> Run the following command from the guest VM console: cp ipl c To list the agents and their properties, enter the following command: oc -n <hosted_control_plane_namespace> get agents See the following example output: NAME CLUSTER APPROVED ROLE STAGE 50c23cda-cedc-9bbd-bcf1-9b3a5c75804d auto-assign 5e498cd3-542c-e54f-0c58-ed43e28b568a auto-assign Run the following command to approve the agent. Optional: You can set the agent ID <installation_disk_id> and <hostname> in the specification. oc -n <hosted_control_plane_namespace> patch agent 50c23cda-cedc-9bbd-bcf1-9b3a5c75804d -p '{"spec":{"installation_disk_id":"/dev/sda","approved":true,"hostname":"worker-zvm-0.hostedn.example.com"}}' --type merge Run the following command to verify that the agents are approved: oc -n <hosted_control_plane_namespace> get agents Example output NAME CLUSTER APPROVED ROLE STAGE 50c23cda-cedc-9bbd-bcf1-9b3a5c75804d true auto-assign 5e498cd3-542c-e54f-0c58-ed43e28b568a true auto-assign 1.8.10.5. Configuring DNS for hosted control plane with IBM Z The API server for the hosted cluster is exposed as a 'NodePort' service. A DNS entry must exist for the api.<hosted-cluster-name>.<base-domain> that points to the destination where the API server is reachable. The DNS entry can be as simple as a record that points to one of the nodes in the managed cluster that is running the hosted control plane. The entry can also point to a load balancer deployed to redirect incoming traffic to the Ingress pods. See the following example of DNS configuration: USD cat /var/named/<example.krnl.es.zone> See the following example output: USD TTL 900 @ IN SOA bastion.example.krnl.es.com. hostmaster.example.krnl.es.com.

For IBM z/VM, add IP addresses that correspond to the IP address of the agent. compute-0 IN A 1xx.2x.2xx.1yy compute-1 IN A 1xx.2x.2xx.1yy 1.8.10.6. Creating an InfraEnv resource for hosted control planes on x86 bare metal for IBM Z compute nodes An InfraEnv is an environment where hosts that are booted with PXE images can join as agents. In this case, the agents are created in the same namespace as your hosted control plane. See the following procedure to create an InfraEnv resource: Create a YAML file to contain the configuration. See the following example: apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv metadata: name: <hosted-cluster-name> namespace: <hosted-control-plane-namespace> spec: cpuArchitecture: s390x pullSecretRef: name: pull-secret sshAuthorizedKey: <ssh-public-key> Save the file as infraenv-config.yaml . Apply the configuration by entering the following command: To fetch the URL to download the PXE images, such as, initrd.img , kernel.img , or rootfs.img , which allows IBM Z machines to join as agents, enter the following command: 1.8.10.7. Scaling the NodePool object for a hosted cluster on IBM Z The NodePool object is created when you create a hosted cluster. By scaling the NodePool object, you can add more compute nodes to the hosted control plane. Run the following command to scale the NodePool object to two nodes: oc -n <clusters_namespace> scale nodepool <nodepool_name> --replicas 2 The Cluster API agent provider randomly picks two agents that are then assigned to the hosted cluster. Those agents go through different states and finally join the hosted cluster as OpenShift Container Platform nodes. The agents pass through the transition phases in the following order: binding discovering insufficient installing installing-in-progress added-to-existing-cluster Run the following command to see the status of a specific scaled agent: oc -n <hosted_control_plane_namespace> get agent -o jsonpath='{range .items[*]}BMH: {@.metadata.labels.agent-install\.openshift\.io/bmh} Agent: {@.metadata.name} State: {@.status.debugInfo.state}{"\n"}{end}' See the following output: BMH: Agent: 50c23cda-cedc-9bbd-bcf1-9b3a5c75804d State: known-unbound BMH: Agent: 5e498cd3-542c-e54f-0c58-ed43e28b568a State: insufficient Run the following command to see the transition phases: oc -n <hosted_control_plane_namespace> get agent See the following output: NAME CLUSTER APPROVED ROLE STAGE 50c23cda-cedc-9bbd-bcf1-9b3a5c75804d hosted-forwarder true auto-assign 5e498cd3-542c-e54f-0c58-ed43e28b568a true auto-assign da503cf1-a347-44f2-875c-4960ddb04091 hosted-forwarder true auto-assign Run the following command to generate the kubeconfig file to access the hosted cluster: hcp create kubeconfig --namespace <clusters_namespace> --name <hosted_cluster_namespace> > <hosted_cluster_name>.kubeconfig After the agents reach the added-to-existing-cluster state, verify that you can see the OpenShift Container Platform nodes by entering the following command: oc --kubeconfig <hosted_cluster_name>.kubeconfig get nodes See the following output: NAME STATUS ROLES AGE VERSION worker-zvm-0.hostedn.example.com Ready worker 5m41s v1.24.0+3882f8f worker-zvm-1.hostedn.example.com Ready worker 6m3s v1.24.0+3882f8f Cluster Operators start to reconcile by adding workloads to the nodes.

For an output example, see the Initial Operator configuration section in the OpenShift Container Platform documentation. 1.8.10.8. Destroying a hosted cluster on x86 bare metal with IBM Z compute nodes To destroy a hosted cluster on x86 bare metal with IBM Z compute nodes and its managed cluster resource, complete the following steps: Run the following command to scale the NodePool object to zero (0) nodes: oc -n <clusters_namespace> scale nodepool <nodepool_name> --replicas 0 After the node pool is scaled to 0, the compute nodes are detached from the hosted cluster. If the compute nodes are not detached from the hosted cluster or are stuck in the Notready state, delete the compute nodes manually by running the following command: oc --kubeconfig <hosted_clusted_name>.kubeconfig delete node <comopute_node_name> Verify the compute nodes status by entering the following command: oc --kubeconfig <hosted_cluster_name>.kubeconfig get nodes After the compute nodes are detached from the hosted cluster, the status of the agents is changed to auto-assign . Delete the agents from the cluster by running the following command: oc -n <hosted_control_plane_namespace> delete agent <agent_name> Note: You can delete the virtual machines that you created as agents after you delete the agents from the cluster. Run the following command by using the hcp command-line to destroy the hosted control plane: hcp destroy cluster agent --name <hosted_cluster_name> --namespace <clusters_namepsace> 1.8.11. Managing hosted control plane clusters on OpenShift Virtualization With hosted control planes and Red Hat OpenShift Virtualization, you can create OpenShift Container Platform clusters with worker nodes that are hosted by KubeVirt virtual machines. Hosted control planes on OpenShift Virtualization provides several benefits: Enhances resource usage by packing hosted control planes and hosted clusters in the same underlying bare metal infrastructure Separates hosted control planes and hosted clusters to provide strong isolation Reduces cluster provision time by eliminating the bare metal node bootstrapping process Manages many releases under the same base OpenShift Container Platform cluster The hosted control planes feature is enabled by default. You can use the hosted control plane command line interface, hcp , to create an OpenShift Container Platform hosted cluster. The hosted cluster is automatically imported as a managed cluster. If you want to disable this automatic import feature, see Disabling the automatic import of hosted clusters into multicluster engine operator . Important: Run the hub cluster and workers on the same platform for hosted control planes. Each hosted cluster must have a cluster-wide unique name. A hosted cluster name cannot be the same as any existing managed cluster in order for multicluster engine operator to manage it. Do not use clusters as a hosted cluster name. A hosted cluster cannot be created in the namespace of a multicluster engine operator managed cluster. When you configure storage for hosted control planes, consider the recommended etcd practices. To ensure that you meet the latency requirements, dedicate a fast storage device to all hosted control plane etcd instances that run on each control-plane node. You can use LVM storage to configure a local storage class for hosted etcd pods. For more information, see Recommended etcd practices and Persistent storage using logical volume manager storage in the OpenShift Container Platform documentation. 1.8.11.1. Prerequisites You must meet the following prerequisites to create an OpenShift Container Platform cluster on OpenShift Virtualization: You need administrator access to an OpenShift Container Platform cluster, version 4.14 or later, specified by the KUBECONFIG environment variable. The OpenShift Container Platform hosting cluster must have wildcard DNS routes enabled, as shown in the following DNS: The OpenShift Container Platform hosting cluster must have OpenShift Virtualization, version 4.14 or later, installed on it. For more information, see Installing OpenShift Virtualization using the web console . The OpenShift Container Platform hosting cluster must be configured with OVNKubernetes as the default pod network CNI. The OpenShift Container Platform hosting cluster must have a default storage class. For more information, see Postinstallation storage configuration . The following example shows how to set a default storage class: You need a valid pull secret file for the quay.io/openshift-release-dev repository. For more information, see Install OpenShift on any x86_64 platform with user-provisioned infrastructure . You need to install the hosted control plane command line interface . Before you can provision your cluster, you need to configure a load balancer. For more information, see Optional: Configuring MetalLB . For optimal network performance, use a network maximum transmission unit (MTU) of 9000 or greater on the OpenShift Container Platform cluster that hosts the KubeVirt virtual machines. If you use a lower MTU setting, network latency and the throughput of the hosted pods are affected. Enable multiqueue on node pools only when the MTU is 9000 or greater. The multicluster engine operator must have at least one managed OpenShift Container Platform cluster. The local-cluster is automatically imported. See Advanced configuration for more information about the local-cluster . You can check the status of your hub cluster by running the following command: 1.8.11.2. Firewall and port requirements Ensure that you meet the firewall and port requirements so that ports can communicate between the management cluster, the control plane, and hosted clusters: The kube-apiserver service runs on port 6443 by default and requires ingress access for communication between the control plane components. If you use the NodePort publishing strategy, ensure that the node port that is assigned to the kube-apiserver service is exposed. If you use MetalLB load balancing, allow ingress access to the IP range that is used for load balancer IP addresses. If you use the NodePort publishing strategy, use a firewall rule for the ignition-server and Oauth-server settings. The konnectivity agent, which establishes a reverse tunnel to allow bi-directional communication on the hosted cluster, requires egress access to the cluster API server address on port 6443. With that egress access, the agent can reach the kube-apiserver service. If the cluster API server address is an internal IP address, allow access from the workload subnets to the IP address on port 6443. If the address is an external IP address, allow egress on port 6443 to that external IP address from the nodes. If you change the default port of 6443, adjust the rules to reflect that change. Ensure that you open any ports that are required by the workloads that run in the clusters. Use firewall rules, security groups, or other access controls to restrict access to only required sources. Avoid exposing ports publicly unless necessary. For production deployments, use a load balancer to simplify access through a single IP address.

To configure hosted control planes on Red Hat OpenShift Virtualization in a disconnected environment, see Configuring hosted control planes in a disconnected environment . To disable the hosted control planes feature or, if you already disabled it and want to manually enable it, see Enabling or disabling the hosted control planes feature . To manage hosted clusters by running Red Hat Ansible Automation Platform jobs, see Configuring Ansible Automation Platform jobs to run on hosted clusters . 1.8.11.3. Creating a hosted cluster with the KubeVirt platform With OpenShift Container Platform 4.14 and later, you can create a cluster with KubeVirt, to include creating with an external infrastructure. Learn more about the process to create with KubeVirt: Creating a hosted cluster Creating a hosted cluster by using external infrastructure 1.8.11.3.1. Creating a hosted cluster To create a hosted cluster, use the hosted control plane command line interface, hcp : 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the worker count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify a value for memory, for example, 6Gi . 5 Specify a value for CPU, for example, 2 . 6 Specify the etcd storage class name, for example, lvm-storageclass . Note: You can use the --release-image flag to set up the hosted cluster with a specific OpenShift Container Platform release. A default node pool is created for the cluster with two virtual machine worker replicas according to the --node-pool-replicas flag. After a few moments, verify that the hosted control plane pods are running by entering the following command: See the following example output: A hosted cluster that has worker nodes that are backed by KubeVirt virtual machines typically takes 10-15 minutes to be fully provisioned. To check the status of the hosted cluster, see the corresponding HostedCluster resource by entering the following command: See the following example output, which illustrates a fully provisioned HostedCluster object: Replace 4.x.0 with the supported OpenShift Container Platform version that you want to use. Access the hosted cluster by following the instructions in Accessing the hosted cluster . 1.8.11.3.2. Creating a hosted cluster by using external infrastructure By default, the HyperShift Operator hosts both the control plane pods of the hosted cluster and the KubeVirt worker VMs within the same cluster. With the external infrastructure feature, you can place the worker node VMs on a separate cluster from the control plane pods. The management cluster is the OpenShift Container Platform cluster that runs the HyperShift Operator and hosts the control plane pods for a hosted cluster. The infrastructure cluster is the OpenShift Container Platform cluster that runs the KubeVirt worker VMs for a hosted cluster. By default, the management cluster also acts as the infrastructure cluster that hosts VMs. However, for external infrastructure, the management and infrastructure clusters are different. 1.8.11.3.2.1. Prerequisites for external infrastructure You must have a namespace on the external infrastructure cluster for the KubeVirt nodes to be hosted in. You must have a kubeconfig file for the external infrastructure cluster. 1.8.11.3.2.2. Creating a hosted cluster by using the hcp command line interface You can create a hosted cluster by using the hcp command line interface. To place the KubeVirt worker VMs on the infrastructure cluster, use the --infra-kubeconfig-file and --infra-namespace arguments, as shown in the following example: 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the worker count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify a value for memory, for example, 6Gi . 5 Specify a value for CPU, for example, 2 . 6 Specify the infrastructure namespace, for example, clusters-example . 7 Specify the path to your kubeconfig file for the infrastructure cluster, for example, /user/name/external-infra-kubeconfig . After you enter that command, the control plane pods are hosted on the management cluster that the HyperShift Operator runs on, and the KubeVirt VMs are hosted on a separate infrastructure cluster. Access the hosted cluster by following the instructions in Accessing the hosted cluster . 1.8.11.3.3. Creating a hosted cluster by using the console To create a hosted cluster with the KubeVirt platform by using the console, complete the following steps: Open the OpenShift Container Platform web console and log in by entering your administrator credentials. For instructions to open the console, see Accessing the web console in the OpenShift Container Platform documentation. In the console header, ensure that All Clusters is selected. Click Infrastructure > Clusters . Click Create cluster > Red Hat OpenShift Virtualization > Hosted . On the Create cluster page, follow the prompts to enter details about the cluster and node pools. Notes: If you want to use predefined values to automatically populate fields in the console, you can create a Red Hat OpenShift Virtualization credential. For more information, see Creating a credential for an on-premises environment . On the Cluster details page, the pull secret is your OpenShift Container Platform pull secret that you use to access OpenShift Container Platform resources. If you selected a Red Hat OpenShift Virtualization credential, the pull secret is automatically populated. Review your entries and click Create . The Hosted cluster view is displayed. Monitor the deployment of the hosted cluster in the Hosted cluster view. If you do not see information about the hosted cluster, ensure that All Clusters is selected, and click the cluster name. Wait until the control plane components are ready. This process can take a few minutes. To view the node pool status, scroll to the NodePool section. The process to install the nodes takes about 10 minutes. You can also click Nodes to confirm whether the nodes joined the hosted cluster. 1.8.11.3.4. Additional resources To create credentials that you can reuse when you create a hosted cluster with the console, see Creating a credential for an on-premises environment . To access a hosted cluster, see Accessing the hosted cluster . 1.8.11.4. Default ingress and DNS behavior Every OpenShift Container Platform cluster includes a default application Ingress Controller, which must have an wildcard DNS record associated with it. By default, hosted clusters that are created by using the HyperShift KubeVirt provider automatically become a subdomain of the OpenShift Container Platform cluster that the KubeVirt virtual machines run on. For example, your OpenShift Container Platform cluster might have the following default ingress DNS entry: *.apps.mgmt-cluster.example.com As a result, a KubeVirt hosted cluster that is named guest and that runs on that underlying OpenShift Container Platform cluster has the following default ingress: *.apps.guest.apps.mgmt-cluster.example.com For the default ingress DNS to work properly, the cluster that hosts the KubeVirt virtual machines must allow wildcard DNS routes. You can configure this behavior by entering the following command: Note: When you use the default hosted cluster ingress, connectivity is limited to HTTPS traffic over port 443. Plain HTTP traffic over port 80 is rejected. This limitation applies to only the default ingress behavior. 1.8.11.4.1. Customizing ingress and DNS behavior If you do not want to use the default ingress and DNS behavior, you can configure a KubeVirt hosted cluster with a unique base domain at creation time. This option requires manual configuration steps during creation and involves three main steps: cluster creation, load balancer creation, and wildcard DNS configuration. 1.8.11.4.1.1. Deploying a hosted cluster that specifies the base domain To create a hosted cluster that specifies the base domain, enter the following command: 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the worker count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify a value for memory, for example, 6Gi . 5 Specify a value for CPU, for example, 2 . 6 Specify the base domain, for example, hypershift.lab . As a result, the hosted cluster has an ingress wildcard that is configured for the cluster name and the base domain, for example, .apps.example.hypershift.lab . The hosted cluster remains in Partial status. Because, after creating a hosted cluster with unique base domain, you must configure the required DNS records and load balancer. View the status of your hosted cluster by entering the following command: See the following example output: Access the cluster by entering the following commands: See the following example output: Replace 4.x.0 with the supported OpenShift Container Platform version that you want to use. The steps fixes the errors in the output. Note: If your hosted cluster is on bare metal, you might need MetalLB to set up load balancer services. For more information, see Optional: Configuring MetalLB . 1.8.11.4.1.2. Setting up the load balancer Set up the load balancer service that routes ingress traffic to the KubeVirt VMs and assigns a wildcard DNS entry to the load balancer IP address. A NodePort service that exposes the hosted cluster ingress already exists. You can export the node ports and create the load balancer service that targets those ports. Get the HTTP node port by entering the following command: Note the HTTP node port value to use in the step. Get the HTTPS node port by entering the following command: Note the HTTPS node port value to use in the step. Create the load balancer service by entering the following command: 1 Specify the HTTPS node port value that you noted in the step. 2 Specify the HTTP node port value that you noted in the step. 1.8.11.4.1.3. Setting up a wildcard DNS Set up up a wildcard DNS record or CNAME that references the external IP of the load balancer service. Get the external IP address by entering the following command: See the following example output: Configure a wildcard DNS entry that references the external IP address. View the following example DNS entry: *.apps.<hosted-cluster-name\>.<base-domain\>. The DNS entry must be able to route inside and outside of the cluster. See the following DNS resolutions example: Check that hosted cluster status has moved from Partial to Completed by entering the following command: See the following example output: Replace 4.x.0 with the supported OpenShift Container Platform version that you want to use. 1.8.11.4.1.4. Additional resources Managing hosted control plane clusters on OpenShift Virtualization Optional: Configuring MetalLB Return to the beginning of this topic, Default ingress and DNS behavior . 1.8.11.5. Optional: Configuring MetalLB You must install the MetalLB Operator before configuring MetalLB. For more information, see Installing the MetalLB Operator in the OpenShift Container Platform documentation. Perform the following steps to configure MetalLB on your guest cluster: Create a MetalLB resource by saving the following sample YAML content in the configure-metallb.yaml file: apiVersion: metallb.io/v1beta1 kind: MetalLB metadata: name: metallb namespace: metallb-system Apply the YAML content by entering the following command: oc apply -f configure-metallb.yaml See the following example output: Create a IPAddressPool resource by saving the following sample YAML content in the create-ip-address-pool.yaml file: apiVersion: metallb.io/v1beta1 kind: IPAddressPool metadata: name: metallb namespace: metallb-system spec: addresses: - 192.168.216.32-192.168.216.122 1 1 Create an address pool with an available range of IP addresses within the node network. Replace the IP address range with an unused pool of available IP addresses in your network. Apply the YAML content by entering the following command: oc apply -f create-ip-address-pool.yaml See the following example output: Create a L2Advertisement resource by saving the following sample YAML content in the l2advertisement.yaml file: apiVersion: metallb.io/v1beta1 kind: L2Advertisement metadata: name: l2advertisement namespace: metallb-system spec: ipAddressPools: - metallb Apply the YAML content by entering the following command: oc apply -f l2advertisement.yaml See the following example output: 1.8.11.5.1. Additional resources For more information about MetalLB, see Installing the MetalLB Operator . 1.8.11.6. Configuring additional networks, guaranteed CPUs, and VM scheduling for node pools If you need to configure additional networks for node pools, request a guaranteed CPU access for Virtual Machines (VMs), or manage scheduling of KubeVirt VMs, see the following procedures. 1.8.11.6.1. Adding multiple networks to a node pool By default, nodes generated by a node pool are attached to the pod network. You can attach additional networks to the nodes by using Multus and NetworkAttachmentDefinitions. To add multiple networks to nodes, use the --additional-network argument by running the following command: hcp create cluster kubevirt \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <worker_node_count> \ 2 --pull-secret <path_to_pull_secret> \ 3 --memory <memory> \ 4 --cores <cpu> \ 5 --additional-network name:<namespace/name> \ 6 --additional-network name:<namespace/name> 1 Specify the name of your hosted cluster, for instance, example . 2 Specify your worker node count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify the memory value, for example, 8Gi . 5 Specify the CPU value, for example, 2 . 6 Set the value of the -additional-network argument to name:<namespace/name> . Replace <namespace/name> with a namespace and name of your NetworkAttachmentDefinitions. 1.8.11.6.1.1. Using an additional network as default You can add your additional network as a default network for the nodes by disabling the default pod network. To add an additional network as default to your nodes, run the following command: hcp create cluster kubevirt \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <worker_node_count> \ 2 --pull-secret <path_to_pull_secret> \ 3 --memory <memory> \ 4 --cores <cpu> \ 5 --attach-default-network false \ 6 --additional-network name:<namespace>/<network_name> 7 1 Specify the name of your hosted cluster, for instance, example . 2 Specify your worker node count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify the memory value, for example, 8Gi . 5 Specify the CPU value, for example, 2 . 6 The --attach-default-network false argument disables the default pod network. 7 Specify the additional network that you want to add to your nodes, for example, name:my-namespace/my-network . 1.8.11.6.2. Requesting guaranteed CPU resources By default, KubeVirt VMs might share its CPUs with other workloads on a node. This might impact performance of a VM. To avoid the performance impact, you can request a guaranteed CPU access for VMs. To request guaranteed CPU resources, set the --qos-class argument to Guaranteed by running the following command: hcp create cluster kubevirt \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <worker_node_count> \ 2 --pull-secret <path_to_pull_secret> \ 3 --memory <memory> \ 4 --cores <cpu> \ 5 --qos-class Guaranteed 6 1 Specify the name of your hosted cluster, for instance, example . 2 Specify your worker node count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify the memory value, for example, 8Gi . 5 Specify the CPU value, for example, 2 . 6 The --qos-class Guaranteed argument guarantees that the specified number of CPU resources are assigned to VMs. 1.8.11.6.3. Scheduling KubeVirt VMs on a set of nodes By default, KubeVirt VMs created by a node pool are scheduled to any available nodes. You can schedule KubeVirt VMs on a specific set of nodes that has enough capacity to run the VM. To schedule KubeVirt VMs within a node pool on a specific set of nodes, use the --vm-node-selector argument by running the following command: hcp create cluster kubevirt \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <worker_node_count> \ 2 --pull-secret <path_to_pull_secret> \ 3 --memory <memory> \ 4 --cores <cpu> \ 5 --vm-node-selector <label_key>=<label_value>,<label_key>=<label_value> 6 1 Specify the name of your hosted cluster, for instance, example . 2 Specify your worker node count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify the memory value, for example, 8Gi . 5 Specify the CPU value, for example, 2 . 6 The --vm-node-selector flag defines a specific set of nodes that contains the key-value pairs. Replace <label_key> and <label_value> with the key and value of your labels respectively. 1.8.11.7. Scaling a node pool You can manually scale a node pool by using the oc scale command: After a few moments, enter the following command to see the status of the node pool: See the following example output: 1.8.11.7.1. Adding node pools You can create node pools for a hosted cluster by specifying a name, number of replicas, and any additional information, such as memory and CPU requirements. To create a node pool, enter the following information. In this example, the node pool has more CPUs assigned to the VMs: Check the status of the node pool by listing nodepool resources in the clusters namespace: See the following example output: Replace 4.x.0 with the supported OpenShift Container Platform version that you want to use. After some time, you can check the status of the node pool by entering the following command: See the following example output: Verify that the node pool is in the status that you expect by entering this command: See the following example output: Replace 4.x.0 with the supported OpenShift Container Platform version that you want to use. 1.8.11.7.1.1. Additional resources Managing hosted control plane clusters on OpenShift Virtualization To scale down the data plane to zero, see Scaling down the data plane to zero . 1.8.11.8. Verifying hosted cluster creation on OpenShift Virtualization To verify that your hosted cluster was successfully created, complete the following steps. Verify that the HostedCluster resource transitioned to the completed state by entering the following command: See the following example output: Verify that all the cluster operators in the hosted cluster are online by entering the following commands: See the following example output: 1.8.11.9. Configuring storage for hosted control planes on OpenShift Virtualization If you do not provide any advanced storage configuration, the default storage class is used for the KubeVirt virtual machine (VM) images, the KubeVirt Container Storage Interface (CSI) mapping, and the etcd volumes. The following table lists the capabilities that the infrastructure must provide to support persistent storage in a hosted cluster: Table 1.13. Persistent storage modes in a hosted cluster Infrastructure CSI provider Hosted cluster CSI provider Hosted cluster capabilities Notes Any RWX Block CSI provider kubevirt-csi Basic: RWO Block and File , RWX Block and Snapshot Recommended Any RWX Block CSI provider Red Hat OpenShift Data Foundation external mode Red Hat OpenShift Data Foundation feature set Any RWX Block CSI provider Red Hat OpenShift Data Foundation internal mode Red Hat OpenShift Data Foundation feature set Do not use 1.8.11.9.1. Mapping KubeVirt CSI storage classes KubeVirt CSI supports mapping a infrastructure storage class that is capable of ReadWriteMany (RWX) access. You can map the infrastructure storage class to hosted storage class during cluster creation. To map the infrastructure storage class to the hosted storage class, use the --infra-storage-class-mapping argument by running the following command: hcp create cluster kubevirt \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <worker_node_count> \ 2 --pull-secret <path_to_pull_secret> \ 3 --memory <memory> \ 4 --cores <cpu> \ 5 --infra-storage-class-mapping=<infrastructure_storage_class>/<hosted_storage_class> \ 6 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the worker count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify a value for memory, for example, 8Gi . 5 Specify a value for CPU, for example, 2 . 6 Replace <infrastructure_storage_class> with the infrastructure storage class name and <hosted_storage_class> with the hosted cluster storage class name. You can use the --infra-storage-class-mapping argument multiple times within the hcp create cluster command. After you create the hosted cluster, the infrastructure storage class is visible within the hosted cluster. When you create a Persistent Volume Claim (PVC) within the hosted cluster that uses one of those storage classes, KubeVirt CSI provisions that volume by using the infrastructure storage class mapping that you configured during cluster creation. Note: KubeVirt CSI supports mapping only an infrastructure storage class that is capable of RWX access. The following table shows how volume and access mode capabilities map to KubeVirt CSI storage classes: Table 1.14. Mapping KubeVirt CSI storage classes to access and volume modes Infrastructure CSI capability Hosted cluster CSI capability VM live migration support Notes RWX: Block or Filesystem ReadWriteOnce (RWO) Block or Filesystem RWX Block only Supported Use Block mode because Filesystem volume mode results in degraded hosted Block mode performance. RWX Block volume mode is supported only when the hosted cluster is OpenShift Container Platform 4.16 or later. RWO Block storage RWO Block storage or Filesystem Not supported Lack of live migration support affects the ability to update the underlying infrastructure cluster that hosts the KubeVirt VMs. RWO FileSystem RWO Block or Filesystem Not supported Lack of live migration support affects the ability to update the underlying infrastructure cluster that hosts the KubeVirt VMs. Use of the infrastructure Filesystem volume mode results in degraded hosted Block mode performance. 1.8.11.9.2. Mapping a single KubeVirt CSI volume snapshot class You can expose your infrastructure volume snapshot class to the hosted cluster by using KubeVirt CSI. To map your volume snapshot class to the hosted cluster, use the --infra-volumesnapshot-class-mapping argument when creating a hosted cluster. Run the following command: hcp create cluster kubevirt \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <worker_node_count> \ 2 --pull-secret <path_to_pull_secret> \ 3 --memory <memory> \ 4 --cores <cpu> \ 5 --infra-storage-class-mapping=<infrastructure_storage_class>/<hosted_storage_class> \ 6 --infra-volumesnapshot-class-mapping=<infrastructure_volume_snapshot_class>/<hosted_volume_snapshot_class> 7 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the worker count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify a value for memory, for example, 8Gi . 5 Specify a value for CPU, for example, 2 . 6 Replace <infrastructure_storage_class> with the storage class present in the infrastructure cluster. Replace <hosted_storage_class> with the storage class present in the hosted cluster. 7 Replace <infrastructure_volume_snapshot_class> with the volume snapshot class present in the infrastructure cluster. Replace <hosted_volume_snapshot_class> with the volume snapshot class present in the hosted cluster. Note: If you do not use the --infra-storage-class-mapping and --infra-volumesnapshot-class-mapping arguments, a hosted cluster is created with the default storage class and the volume snapshot class. Therefore, you must set the default storage class and the volume snapshot class in the infrastructure cluster. 1.8.11.9.3. Mapping multiple KubeVirt CSI volume snapshot classes You can map multiple volume snapshot classes to the hosted cluster by assigning them to a specific group. The infrastructure storage class and the volume snapshot class are compatible with each other only if they belong to a same group. To map multiple volume snapshot classes to the hosted cluster, use the group option when creating a hosted cluster. Run the following command: hcp create cluster kubevirt \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <worker_node_count> \ 2 --pull-secret <path_to_pull_secret> \ 3 --memory <memory> \ 4 --cores <cpu> \ 5 --infra-storage-class-mapping=<infrastructure_storage_class>/<hosted_storage_class>,group=<group_name> \ 6 --infra-storage-class-mapping=<infrastructure_storage_class>/<hosted_storage_class>,group=<group_name> \ --infra-storage-class-mapping=<infrastructure_storage_class>/<hosted_storage_class>,group=<group_name> \ --infra-volumesnapshot-class-mapping=<infrastructure_volume_snapshot_class>/<hosted_volume_snapshot_class>,group=<group_name> \ 7 --infra-volumesnapshot-class-mapping=<infrastructure_volume_snapshot_class>/<hosted_volume_snapshot_class>,group=<group_name> 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the worker count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify a value for memory, for example, 8Gi . 5 Specify a value for CPU, for example, 2 . 6 Replace <infrastructure_storage_class> with the storage class present in the infrastructure cluster. Replace <hosted_storage_class> with the storage class present in the hosted cluster. Replace <group_name> with the group name. For example, infra-storage-class-mygroup/hosted-storage-class-mygroup,group=mygroup and infra-storage-class-mymap/hosted-storage-class-mymap,group=mymap . 7 Replace <infrastructure_volume_snapshot_class> with the volume snapshot class present in the infrastructure cluster. Replace <hosted_volume_snapshot_class> with the volume snapshot class present in the hosted cluster. For example, infra-vol-snap-mygroup/hosted-vol-snap-mygroup,group=mygroup and infra-vol-snap-mymap/hosted-vol-snap-mymap,group=mymap . 1.8.11.9.4. Configuring KubeVirt VM root volume At cluster creation time, you can configure the storage class that is used to host the KubeVirt VM root volumes by using the --root-volume-storage-class argument. To set a custom storage class and volume size for KubeVirt VMs, run the following command: hcp create cluster kubevirt \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <worker_node_count> \ 2 --pull-secret <path_to_pull_secret> \ 3 --memory <memory> \ 4 --cores <cpu> \ 5 --root-volume-storage-class <root_volume_storage_class> \ 6 --root-volume-size <volume_size> 7 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the worker count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify a value for memory, for example, 8Gi . 5 Specify a value for CPU, for example, 2 . 6 Specify a name of the storage class to host the KubeVirt VM root volumes, for example, ocs-storagecluster-ceph-rbd . 7 Specify the volume size, for example, 64 . As a result, you get a hosted cluster created with VMs hosted on PVCs. 1.8.11.9.5. Enabling KubeVirt VM image caching You can use KubeVirt VM image caching to optimize both cluster startup time and storage utilization. KubeVirt VM image caching supports the use of a storage class that is capable of smart cloning and the ReadWriteMany access mode. For more information about smart cloning, see Cloning a data volume using smart-cloning . Image caching works as follows: The VM image is imported to a PVC that is associated with the hosted cluster. A unique clone of that PVC is created for every KubeVirt VM that is added as a worker node to the cluster. Image caching reduces VM startup time by requiring only a single image import. It can further reduce overall cluster storage usage when the storage class supports copy-on-write cloning. To enable image caching, during cluster creation, use the --root-volume-cache-strategy=PVC argument by running the following command: hcp create cluster kubevirt \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <worker_node_count> \ 2 --pull-secret <path_to_pull_secret> \ 3 --memory <memory> \ 4 --cores <cpu> \ 5 --root-volume-cache-strategy=PVC 6 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the worker count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify a value for memory, for example, 8Gi . 5 Specify a value for CPU, for example, 2 . 6 Specify a strategy for image caching, for example, PVC . 1.8.11.9.6. Configuring etcd storage At cluster creation time, you can configure the storage class that is used to host etcd data by using the --etcd-storage-class argument. To configure a storage class for etcd, run the following command: hcp create cluster kubevirt \ --name <hosted_cluster_name> \ 1 --node-pool-replicas <worker_node_count> \ 2 --pull-secret <path_to_pull_secret> \ 3 --memory <memory> \ 4 --cores <cpu> \ 5 --etcd-storage-class=<etcd_storage_class_name> 6 1 Specify the name of your hosted cluster, for instance, example . 2 Specify the worker count, for example, 2 . 3 Specify the path to your pull secret, for example, /user/name/pullsecret . 4 Specify a value for memory, for example, 8Gi . 5 Specify a value for CPU, for example, 2 . 6 Specify the etcd storage class name, for example, lvm-storageclass . If you do not provide an --etcd-storage-class argument, the default storage class is used. 1.8.11.9.6.1. Additional resources Cloning a data volume using smart-cloning 1.8.11.10. Destroying a hosted cluster on OpenShift Virtualization To destroy a hosted cluster and its managed cluster resource, complete the following steps: Delete the managed cluster resource on multicluster engine operator by running the following command: where cluster_name is the name of your cluster. Delete the hosted cluster and its back-end resources by running the following command: Replace names where necessary. 1.8.12. Configuring hosted control planes in a disconnected environment In the context of hosted control planes, a disconnected environment is an OpenShift Container Platform deployment that is not connected to the internet and that uses hosted control planes as a base. Technology Preview: You can deploy hosted control planes in a disconnected environment on bare-metal platforms by using an IPv4 or IPv6 network. In addition, hosted control planes in a disconnected environment is available on a dual-stack network as a Technology Preview feature. If you use the Red Hat OpenShift Virtualization platform, hosted control planes in a disconnected environment is available as a Technology Preview feature only. 1.8.12.1. Disconnected environment architecture When you provision hosted control planes on bare metal, you use the Agent platform. The Agent platform and multicluster engine operator work together to enable disconnected deployments. The Agent platform uses the central infrastructure management service to add worker nodes to a hosted cluster. For an introduction to the central infrastructure management service, see Enabling the central infrastructure management service . The following diagram illustrates an example architecture of a disconnected environment: Configure infrastructure services, including the registry certificate deployment with TLS support, web server, and DNS, to ensure that the disconnected deployment works. Create a config map in the openshift-config namespace. In this example, the config map is named registry-config . The content of the config map is the Registry CA certificate. The data field of the config map must contain the following key/value: Key: <registry_dns_domain_name>..<port> , for example, registry.hypershiftdomain.lab..5000: . Ensure that you place .. after the registry DNS domain name when you specify a port. Value: The certificate content For more information about creating a config map, see Configuring TLS certificates for an IPv4 network . Modify the images.config.openshift.io custom resource (CR) specification and adds a new field named additionalTrustedCA with a value of name: registry-config . Create a config map that contains two data fields. One field contains the registries.conf file in RAW format, and the other field contains the Registry CA and is named ca-bundle.crt . The config map belongs to the multicluster-engine namespace, and the config map name is referenced in other objects. For an example of a config map, see the following sample configuration: In the multicluster engine operator namespace, you create the multiclusterengine CR, which enables both the Agent and hypershift-addon add-ons. The multicluster engine operator namespace must contain the config maps to modify behavior in a disconnected deployment. The namespace also contains the multicluster-engine , assisted-service , and hypershift-addon-manager pods. Create the following objects that are necessary to deploy the hosted cluster: Secrets: Secrets contain the pull secret, SSH key, and etcd encryption key. Config map: The config map contains the CA certificate of the private registry. HostedCluster : The HostedCluster resource defines the configuration of the cluster that the user intends to create. NodePool : The NodePool resource identifies the node pool that references the machines to use for the data plane. After you create the hosted cluster objects, the HyperShift Operator establishes the HostedControlPlane namespace to accommodate control plane pods. The namespace also hosts components such as Agents, bare metal hosts (BMHs), and the InfraEnv resource. Later, you create the InfraEnv resource, and after ISO creation, you create the BMHs and their secrets that contain baseboard management controller (BMC) credentials. The Metal3 Operator in the openshift-machine-api namespace inspects the new BMHs. Then, the Metal3 Operator tries to connect to the BMCs to start them by using the configured LiveISO and RootFS values that are specified through the AgentServiceConfig CR in the multicluster engine operator namespace. After the worker nodes of the HostedCluster resource are started, an Agent container is started. This agent establishes contact with the Assisted Service, which orchestrates the actions to complete the deployment. Initially, you need to scale the NodePool resource to the number of worker nodes for the HostedCluster resource. The Assisted Service manages the remaining tasks. At this point, you wait for the deployment process to be completed. 1.8.12.2. Prerequisites To configure hosted control planes in a disconnected environment, you must meet the following prerequisites: CPU: The number of CPUs provided determines how many hosted clusters can run concurrently. In general, use 16 CPUs for each node for 3 nodes. For minimal development, you can use 12 CPUs for each node for 3 nodes. Memory: The amount of RAM affects how many hosted clusters can be hosted. Use 48 GB of RAM for each node. For minimal development, 18 GB of RAM might be sufficient. Storage: Use SSD storage for multicluster engine operator. Management cluster: 250 GB. Registry: The storage needed depends on the number of releases, operators, and images that are hosted. An acceptable number might be 500 GB, preferably separated from the disk that hosts the hosted cluster. Web server: The storage needed depends on the number of ISOs and images that are hosted. An acceptable number might be 500 GB. Production: For a production environment, separate the management cluster, the registry, and the web server on different disks. This example illustrates a possible configuration for production: Registry: 2 TB Management cluster: 500 GB Web server: 2 TB 1.8.12.3. Extracting the OpenShift Container Platform release image digest You can extract the OpenShift Container Platform release image digest by using the tagged image. Complete the following steps: Obtain the image digest by running the following command: oc adm release info <tagged_openshift_release_image> | grep "Pull From" Replace <tagged_openshift_release_image> with the tagged image for the supported OpenShift Container Platform version, for example, quay.io/openshift-release-dev/ocp-release:4.14.0-x8_64 . See the following example output: To know more about the image tag and digest, see Referencing images in imagestreams in the OpenShift Container Platform documentation. 1.8.12.3.1. Additional resources Configuring TLS certificates for an IPv4 network Referencing images in imagestreams 1.8.12.4. Monitoring user workload in a disconnected environment The hypershift-addon managed cluster add-on enables the --enable-uwm-telemetry-remote-write option in the HyperShift Operator. By enabling that option, you ensure that user workload monitoring is enabled and that it can remotely write telemetry metrics from control planes. If you installed multicluster engine operator on OpenShift Container Platform clusters that are not connected to the internet, when you try to run the user workload monitoring feature of the HyperShift Operator by entering the following command, the feature fails with an error: The error might look like this example: To avoid that error, you must disable the user workload monitoring option by creating a config map in the local-cluster namespace. You can create the config map either before or after you enable the add-on. The add-on agent reconfigures the HyperShift Operator. Create the following config map: kind: ConfigMap apiVersion: v1 metadata: name: hypershift-operator-install-flags namespace: local-cluster data: installFlagsToAdd: "" installFlagsToRemove: "--enable-uwm-telemetry-remote-write" 1.8.12.4.1. Verifying the status of the hosted control plane feature The hosted control plane feature is enabled by default. If the feature is disabled and you want to enable it, enter the following command. Replace multiclusterengine with the name of your multicluster engine operator instance: When you enable the feature, the hypershift-addon managed cluster add-on is installed in the local-cluster managed cluster, and the add-on agent installs the HyperShift Operator on the multicluster engine operator hub cluster. Confirm that the hypershift-addon managed cluster add-on is installed by entering the following command: See the resulting output: To avoid a timeout during this process, enter the following commands: When the process is complete, the hypershift-addon managed cluster add-on and the HyperShift Operator are installed, and the local-cluster managed cluster is available to host and manage hosted clusters. 1.8.12.4.2. Configuring the hypershift-addon managed cluster add-on to run on an infrastructure node By default, no node placement preference is specified for the hypershift-addon managed cluster add-on. Consider running the add-ons on the infrastructure nodes, because by doing so, you can prevent incurring billing costs against subscription counts and separate maintenance and management tasks. Log in to the hub cluster. Open the hypershift-addon-deploy-config add-on deployment configuration specification for editing by entering the following command: Add the nodePlacement field to the specification, as shown in the following example: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: AddOnDeploymentConfig metadata: name: hypershift-addon-deploy-config namespace: multicluster-engine spec: nodePlacement: nodeSelector: node-role.kubernetes.io/infra: "" tolerations: - effect: NoSchedule key: node-role.kubernetes.io/infra operator: Exists Save the changes. The hypershift-addon managed cluster add-on is deployed on an infrastructure node for new and existing managed clusters. 1.8.12.5. Configuring hosted control planes on an IPv4 network IPv4 is one of the simplest network configurations to deploy hosted control planes in a disconnected environment. IPv4 ranges require fewer external components than IPv6 or dual-stack setups. The process to configure hosted control planes on an IPv4 network involves the following steps, which are described in detail in the sections that follow: Configure the hypervisor for an IPv4 network Configuring DNS for an IPv4 network Deploying a registry for an IPv4 network Setting up a management cluster for an IPv4 network Configuring the web server for an IPv4 network Configuring image mirroring for an IPv4 network Deploying multicluster engine operator for an IPv4 network Configuring TLS certificates for an IPv4 network Deploying the hosted cluster for an IPv4 network Finishing the deployment for an IPv4 network 1.8.12.5.1. Configuring the hypervisor for an IPv4 network The following information applies to virtual machine environments only. 1.8.12.5.1.1. Accessing and deploying packages for a virtual OpenShift Container Platform cluster To deploy a virtual OpenShift Container Platform management cluster, access the required packages by entering the following command: sudo dnf install dnsmasq radvd vim golang podman bind-utils net-tools httpd-tools tree htop strace tmux -y Enable and start the Podman service by entering the following command: systemctl enable --now podman To use kcli to deploy the OpenShift Container Platform management cluster and other virtual components, install and configure the hypervisor by entering the following commands: sudo yum -y install libvirt libvirt-daemon-driver-qemu qemu-kvm sudo usermod -aG qemu,libvirt USD(id -un) sudo newgrp libvirt sudo systemctl enable --now libvirtd sudo dnf -y copr enable karmab/kcli sudo dnf -y install kcli sudo kcli create pool -p /var/lib/libvirt/images default kcli create host kvm -H 127.0.0.1 local sudo setfacl -m u:USD(id -un):rwx /var/lib/libvirt/images kcli create network -c 192.168.122.0/24 default 1.8.12.5.1.2. Enabling the network manager dispatcher Enable the network manager dispatcher to ensure that virtual machines can resolve the required domains, routes, and registries. To enable the network manager dispatcher, in the /etc/NetworkManager/dispatcher.d/ directory, create a script named forcedns that contains the following content, replacing values as necessary to match your environment: #!/bin/bash export IP="192.168.126.1" 1 export BASE_RESOLV_CONF="/run/NetworkManager/resolv.conf" if ! [[ `grep -q "USDIP" /etc/resolv.conf` ]]; then export TMP_FILE=USD(mktemp /etc/forcedns_resolv.conf.XXXXXX) cp USDBASE_RESOLV_CONF USDTMP_FILE chmod --reference=USDBASE_RESOLV_CONF USDTMP_FILE sed -i -e "s/dns.base.domain.name//" -e "s/search /& dns.base.domain.name /" -e "0,/nameserver/s/nameserver/& USDIP\n&/" USDTMP_FILE 2 mv USDTMP_FILE /etc/resolv.conf fi echo "ok" 1 Modify the IP variable to point to the IP address of the hypervisor interface that hosts the OpenShift Container Platform management cluster. 2 Replace dns.base.domain.name with the DNS base domain name. After you create the file, add permissions by entering the following command: chmod 755 /etc/NetworkManager/dispatcher.d/forcedns Run the script and verify that the output returns ok . 1.8.12.5.1.3. Configure BMC access Configure ksushy to simulate baseboard management controllers (BMCs) for the virtual machines. Enter the following commands: sudo dnf install python3-pyOpenSSL.noarch python3-cherrypy -y kcli create sushy-service --ssl --port 9000 sudo systemctl daemon-reload systemctl enable --now ksushy Test whether the service is correctly functioning by entering the following command: systemctl status ksushy 1.8.12.5.1.4. Configuring the hypervisor system to allow connections If you are working in a development environment, configure the hypervisor system to allow various types of connections through different virtual networks within the environment. Note: If you are working in a production environment, you must establish proper rules for the firewalld service and configure SELinux policies to maintain a secure environment. For SELinux, enter the following command: sed -i s/^SELINUX=.*USD/SELINUX=permissive/ /etc/selinux/config; setenforce 0 For firewalld , enter the following command: systemctl disable --now firewalld For libvirtd , enter the following commands: systemctl restart libvirtd systemctl enable --now libvirtd , configure DNS for your environment. 1.8.12.5.1.5. Additional resources For more information about kcli , see the official kcli documentation . 1.8.12.5.2. Configuring DNS for an IPv4 network This step is mandatory for both disconnected and connected environments in both virtual and bare metal environments. The key distinction between virtual and bare metal environment lies in the location where you configure the resources. In a bare-metal environment, use a solution like Bind rather than a lightweight solution like dnsmasq . To configure DNS for an IPv4 network on a virtual environment, see Default ingress and DNS behavior . To configure DNS for an IPv4 network on bare metal, see Configuring DNS on bare metal . , deploy a registry. 1.8.12.5.3. Deploying a registry for an IPv4 network For development environments, deploy a small, self-hosted registry by using a Podman container. For production environments, use an enterprise-hosted registry, such as Red Hat Quay, Nexus, or Artifactory. To deploy a small registry by using Podman, complete the following steps: As a privileged user, access the USD{HOME} directory and create the following script: #!/usr/bin/env bash set -euo pipefail PRIMARY_NIC=USD(ls -1 /sys/class/net | grep -v podman | head -1) export PATH=/root/bin:USDPATH export PULL_SECRET="/root/baremetal/hub/openshift_pull.json" 1 if [[ ! -f USDPULL_SECRET ]];then echo "Pull Secret not found, exiting..." exit 1 fi dnf -y install podman httpd httpd-tools jq skopeo libseccomp-devel export IP=USD(ip -o addr show USDPRIMARY_NIC | head -1 | awk '{print USD4}' | cut -d'/' -f1) REGISTRY_NAME=registry.USD(hostname --long) REGISTRY_USER=dummy REGISTRY_PASSWORD=dummy KEY=USD(echo -n USDREGISTRY_USER:USDREGISTRY_PASSWORD | base64) echo "{\"auths\": {\"USDREGISTRY_NAME:5000\": {\"auth\": \"USDKEY\", \"email\": \"sample-email@domain.ltd\"}}}" > /root/disconnected_pull.json mv USD{PULL_SECRET} /root/openshift_pull.json.old jq ".auths += {\"USDREGISTRY_NAME:5000\": {\"auth\": \"USDKEY\",\"email\": \"sample-email@domain.ltd\"}}" < /root/openshift_pull.json.old > USDPULL_SECRET mkdir -p /opt/registry/{auth,certs,data,conf} cat <<EOF > /opt/registry/conf/config.yml version: 0.1 log: fields: service: registry storage: cache: blobdescriptor: inmemory filesystem: rootdirectory: /var/lib/registry delete: enabled: true http: addr: :5000 headers: X-Content-Type-Options: [nosniff] health: storagedriver: enabled: true interval: 10s threshold: 3 compatibility: schema1: enabled: true EOF openssl req -newkey rsa:4096 -nodes -sha256 -keyout /opt/registry/certs/domain.key -x509 -days 3650 -out /opt/registry/certs/domain.crt -subj "/C=US/ST=Madrid/L=San Bernardo/O=Karmalabs/OU=Guitar/CN=USDREGISTRY_NAME" -addext "subjectAltName=DNS:USDREGISTRY_NAME" cp /opt/registry/certs/domain.crt /etc/pki/ca-trust/source/anchors/ update-ca-trust extract htpasswd -bBc /opt/registry/auth/htpasswd USDREGISTRY_USER USDREGISTRY_PASSWORD podman create --name registry --net host --security-opt label=disable --replace -v /opt/registry/data:/var/lib/registry:z -v /opt/registry/auth:/auth:z -v /opt/registry/conf/config.yml:/etc/docker/registry/config.yml -e "REGISTRY_AUTH=htpasswd" -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry" -e "REGISTRY_HTTP_SECRET=ALongRandomSecretForRegistry" -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd -v /opt/registry/certs:/certs:z -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key docker.io/library/registry:latest [ "USD?" == "0" ] || !! systemctl enable --now registry 1 Replace the location of the PULL_SECRET with the appropriate location for your setup. Name the script file registry.sh and save it. When you run the script, it pulls in the following information: The registry name, based on the hypervisor hostname The necessary credentials and user access details Adjust permissions by adding the execution flag as follows: To run the script without any parameters, enter the following command: The script starts the server. The script uses a systemd service for management purposes. If you need to manage the script, you can use the following commands: The root folder for the registry is in the /opt/registry directory and contains the following subdirectories: certs contains the TLS certificates. auth contains the credentials. data contains the registry images. conf contains the registry configuration. 1.8.12.5.4. Setting up the management cluster for an IPv4 network To set up an OpenShift Container Platform management cluster, you can use dev-scripts, or if you are based on virtual machines, you can use the kcli tool. The following instructions are specific to the kcli tool. Ensure that the right networks are prepared for use in the hypervisor. The networks will host both the management and hosted clusters. Enter the following kcli command: where: -c specifies the CIDR for the network. -P dhcp=false configures the network to disable the DHCP, which is handled by the dnsmasq that you configured. -P dns=false configures the network to disable the DNS, which is also handled by the dnsmasq that you configured. --domain sets the domain to search. dns.base.domain.name is the DNS base domain name. ipv4 is the name of the network that you are creating. After the network is created, review the following output: Ensure that the pull secret and kcli plan files are in place so that you can deploy the OpenShift Container Platform management cluster: Confirm that the pull secret is in the same folder as the kcli plan, and that the pull secret file is named openshift_pull.json . Add the kcli plan, which contains the OpenShift Container Platform definition, in the mgmt-compact-hub-ipv4.yaml file. Ensure that you update the file contents to match your environment: plan: hub-ipv4 force: true version: nightly tag: "4.x.y-x86_64" 1 cluster: "hub-ipv4" domain: dns.base.domain.name api_ip: 192.168.125.10 ingress_ip: 192.168.125.11 disconnected_url: registry.dns.base.domain.name:5000 disconnected_update: true disconnected_user: dummy disconnected_password: dummy disconnected_operators_version: v4.14 disconnected_operators: - name: metallb-operator - name: lvms-operator channels: - name: stable-4.14 disconnected_extra_images: - quay.io/user-name/trbsht:latest - quay.io/user-name/hypershift:BMSelfManage-v4.14-rc-v3 - registry.redhat.io/openshift4/ose-kube-rbac-proxy:v4.10 dualstack: false disk_size: 200 extra_disks: [200] memory: 48000 numcpus: 16 ctlplanes: 3 workers: 0 manifests: extra-manifests metal3: true network: ipv4 users_dev: developer users_devpassword: developer users_admin: admin users_adminpassword: admin metallb_pool: ipv4-virtual-network metallb_ranges: - 192.168.125.150-192.168.125.190 metallb_autoassign: true apps: - users - lvms-operator - metallb-operator vmrules: - hub-bootstrap: nets: - name: ipv4 mac: aa:aa:aa:aa:02:10 - hub-ctlplane-0: nets: - name: ipv4 mac: aa:aa:aa:aa:02:01 - hub-ctlplane-1: nets: - name: ipv4 mac: aa:aa:aa:aa:02:02 - hub-ctlplane-2: nets: - name: ipv4 mac: aa:aa:aa:aa:02:03 1 Replace 4.x.y with the supported OpenShift Container Platform version you want to use. To provision the management cluster, enter the following command: 1.8.12.5.4.1. Additional resources For more information about the parameters in the kcli plan file, see Create a parameters.yml in the official kcli documentation. 1.8.12.5.5. Configuring the web server for an IPv4 network You need to configure an additional web server to host the Red Hat Enterprise Linux CoreOS (RHCOS) images that are associated with the OpenShift Container Platform release that you are deploying as a hosted cluster. To configure the web server, complete the following steps: Extract the openshift-install binary from the OpenShift Container Platform release that you want to use by entering the following command: oc adm -a USD{LOCAL_SECRET_JSON} release extract --command=openshift-install "USD{LOCAL_REGISTRY}/USD{LOCAL_REPOSITORY}:USD{OCP_RELEASE}-USD{ARCHITECTURE}" Run the following script. The script creates a folder in the /opt/srv directory. The folder contains the RHCOS images to provision the worker nodes. #!/bin/bash WEBSRV_FOLDER=/opt/srv ROOTFS_IMG_URL="USD(./openshift-install coreos print-stream-json | jq -r '.architectures.x86_64.artifacts.metal.formats.pxe.rootfs.location')" 1 LIVE_ISO_URL="USD(./openshift-install coreos print-stream-json | jq -r '.architectures.x86_64.artifacts.metal.formats.iso.disk.location')" 2 mkdir -p USD{WEBSRV_FOLDER}/images curl -Lk USD{ROOTFS_IMG_URL} -o USD{WEBSRV_FOLDER}/images/USD{ROOTFS_IMG_URL##*/} curl -Lk USD{LIVE_ISO_URL} -o USD{WEBSRV_FOLDER}/images/USD{LIVE_ISO_URL##*/} chmod -R 755 USD{WEBSRV_FOLDER}/* ## Run Webserver podman ps --noheading | grep -q websrv-ai if [[ USD? == 0 ]];then echo "Launching Registry pod..." /usr/bin/podman run --name websrv-ai --net host -v /opt/srv:/usr/local/apache2/htdocs:z quay.io/alosadag/httpd:p8080 fi 1 You can find the ROOTFS_IMG_URL value on the OpenShift CI Release page. 2 You can find the LIVE_ISO_URL value on the OpenShift CI Release page. After the download is completed, a container runs to host the images on a web server. The container uses a variation of the official HTTPd image, which also enables it to work with IPv6 networks. 1.8.12.5.6. Configuring image mirroring for an IPv4 network Image mirroring is the process of fetching images from external registries, such as registry.redhat.com or quay.io , and storing them in your private registry. 1.8.12.5.6.1. Completing the mirroring process Note: Start the mirroring process after the registry server is running. In the following procedures, the oc-mirror tool is used, which is a binary that uses the ImageSetConfiguration object. In the file, you can specify the following information: The OpenShift Container Platform versions to mirror. The versions are in quay.io . The additional Operators to mirror. Select packages individually. The extra images that you want to add to the repository. To configure image mirroring, complete the following steps: Ensure that your USD{HOME}/.docker/config.json file is updated with the registries that you are going to mirror from and with the private registry that you plan to push the images to. By using the following example, create an ImageSetConfiguration object to use for mirroring. Replace values as needed to match your environment: 1 Replace dns.base.domain.name with the DNS base domain name. 2 Replace 4.x.y with the supported OpenShift Container Platform version you want to use. Start the mirroring process by entering the following command: After the mirroring process is finished, you have a new folder named oc-mirror-workspace/results-XXXXXX/ , which contains the ICSP and the catalog sources to apply on the hosted cluster. Mirror the nightly or CI versions of OpenShift Container Platform by using the oc adm release mirror command. Enter the following command: Replace 4.x.y with the supported OpenShift Container Platform version you want to use. Mirror the latest multicluster engine operator images by following the steps in Install on disconnected networks . 1.8.12.5.6.2. Applying objects in the management cluster After the mirroring process is complete, you need to apply two objects in the management cluster: Image Content Source Policies (ICSP) or Image Digest Mirror Set (IDMS) Catalog sources When you use the oc-mirror tool, the output artifacts are in a folder named oc-mirror-workspace/results-XXXXXX/ . ICSP or IDMS initiates a MachineConfig change that does not restart your nodes but restarts the kubelet on each of them. After the nodes are marked as READY , you need to apply the newly generated catalog sources. The catalog sources initiate actions in the openshift-marketplace Operator, such as downloading the catalog image and processing it to retrieve all the PackageManifests that are included in that image. To check the new sources, run the following command by using the new CatalogSource as a source: To apply the artifacts, complete the following steps: Create the ImageContentSourcePolicy (ICSP) or IDMS artifacts by entering the following command: Wait for the nodes to become ready, and then enter the following command: Mirror the OLM catalogs and configure the hosed cluster to point to the mirror. When you use the management (default) OLMCatalogPlacement mode, the image stream that is used for OLM catalogs is not automatically amended with override information from the ICSP on the management cluster. If the OLM catalogs are properly mirrored to an internal registry by using the original name and tag, add the hypershift.openshift.io/olm-catalogs-is-registry-overrides annotation to the HostedCluster resource. The format is "sr1=dr1,sr2=dr2" , where the source registry string is a key and the destination registry is a value. To bypass the OLM catalog image stream mechanism, use the following four annotations on the HostedCluster resource to directly specify the addresses of the four images to use for OLM operator catalogs: hypershift.openshift.io/certified-operators-catalog-image hypershift.openshift.io/community-operators-catalog-image hypershift.openshift.io/redhat-marketplace-catalog-image hypershift.openshift.io/redhat-operators-catalog-image In this case, the image stream is not created, and you must update the value of the annotations when the internal mirror is refreshed to pull in operator updates. Note: If the override mechanism is required, all four values for the four default catalog sources are needed. 1.8.12.5.6.3. Additional resources If you are working in a virtual environment, after you configure mirroring, ensure that you meet the prerequisites for hosted control planes on OpenShift Virtualization . For more information about mirroring nightly or CI versions of OpenShift Container Platform, see Mirroring images for a disconnected installation using the oc-mirror plugin . 1.8.12.5.7. Deploying multicluster engine operator for an IPv4 network The multicluster engine operator plays a crucial role in deploying clusters across providers. If you already installed Red Hat Advanced Cluster Management, you do not need to install multicluster engine operator because it is automatically installed. If you do not have multicluster engine operator installed, review the following documentation to understand the prerequisites and steps to install it: About cluster lifecycle with multicluster engine operator Installing and upgrading multicluster engine operator 1.8.12.5.7.1. Deploying AgentServiceConfig resources The AgentServiceConfig custom resource is an essential component of the Assisted Service add-on that is part of multicluster engine operator. It is responsible for bare metal cluster deployment. When the add-on is enabled, you deploy the AgentServiceConfig resource to configure the add-on. In addition to configuring the AgentServiceConfig resource, you need to include additional config maps to ensure that multicluster engine operator functions properly in a disconnected environment. Configure the custom registries by adding the following config map, which contains the disconnected details to customize the deployment: --- apiVersion: v1 kind: ConfigMap metadata: name: custom-registries namespace: multicluster-engine labels: app: assisted-service data: ca-bundle.crt: | -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- registries.conf: | unqualified-search-registries = ["registry.access.redhat.com", "docker.io"] [[registry]] prefix = "" location = "registry.redhat.io/openshift4" mirror-by-digest-only = true [[registry.mirror]] location = "registry.dns.base.domain.name:5000/openshift4" 1 [[registry]] prefix = "" location = "registry.redhat.io/rhacm2" mirror-by-digest-only = true ... ... 1 Replace dns.base.domain.name with the DNS base domain name. The object contains two fields: Custom CAs: This field contains the Certificate Authorities (CAs) that are loaded into the various processes of the deployment. Registries: The Registries.conf field contains information about images and namespaces that need to be consumed from a mirror registry rather than the original source registry. Configure the Assisted Service by adding the AssistedServiceConfig object, as shown in the following example: --- apiVersion: agent-install.openshift.io/v1beta1 kind: AgentServiceConfig metadata: annotations: unsupported.agent-install.openshift.io/assisted-service-configmap: assisted-service-config 1 name: agent namespace: multicluster-engine spec: mirrorRegistryRef: name: custom-registries 2 databaseStorage: storageClassName: lvms-vg1 accessModes: - ReadWriteOnce resources: requests: storage: 10Gi filesystemStorage: storageClassName: lvms-vg1 accessModes: - ReadWriteOnce resources: requests: storage: 20Gi osImages: 3 - cpuArchitecture: x86_64 openshiftVersion: "4.14" rootFSUrl: http://registry.dns.base.domain.name:8080/images/rhcos-414.92.202308281054-0-live-rootfs.x86_64.img 4 url: http://registry.dns.base.domain.name:8080/images/rhcos-414.92.202308281054-0-live.x86_64.iso version: 414.92.202308281054-0 1 The metadata.annotations["unsupported.agent-install.openshift.io/assisted-service-configmap"] annotation references the config map name that the Operator consumes to customize behavior. 2 The spec.mirrorRegistryRef.name annotation points to the config map that contains disconnected registry information that the Assisted Service Operator consumes. This config map adds those resources during the deployment process. 3 The spec.osImages field contains different versions available for deployment by this Operator. This field is mandatory. This example assumes that you already downloaded the RootFS and LiveISO files. 4 In the rootFSUrl and url fields, replace dns.base.domain.name with the DNS base domain name. Deploy all of the objects by concatenating them into a single file and applying them to the management cluster. To do so, enter the following command: The command triggers two pods, as shown in this example output: 1 The assisted-image-service pod is responsible for creating the Red Hat Enterprise Linux CoreOS (RHCOS) boot image template, which is customized for each cluster that you deploy. 2 The assisted-service refers to the Operator. 1.8.12.5.8. Configuring TLS certificates for an IPv4 network Several TLS certificates are involved in the process to configure hosted control planes in a disconnected environment. To add a Certificate Authority (CA) to the management cluster, you need to modify the content of the following files in the OpenShift Container Platform control plane and worker nodes: /etc/pki/ca-trust/extracted/pem/ /etc/pki/ca-trust/source/anchors /etc/pki/tls/certs/ To add a CA to the management cluster, complete the following steps: Complete the steps in Updating the CA bundle in the official OpenShift Container Platform documentation. That method involves using the image-registry-operator , which deploys the CAs to the OpenShift Container Platform nodes. If that method does not apply to your situation, check whether the openshift-config namespace in the management cluster contains a config map named user-ca-bundle . If the namespace contains that config map, enter the following command: If the namespace does not contain that config map, enter the following command: 1.8.12.5.9. Deploying the hosted cluster for an IPv4 network A hosted cluster is an OpenShift Container Platform cluster with its control plane and API endpoint hosted on a management cluster. The hosted cluster includes the control plane and its corresponding data plane. Although you can use the console in Red Hat Advanced Cluster Management to create a hosted cluster, the following procedures use manifests, which provide more flexibility for modifying the related artifacts. 1.8.12.5.9.1. Deploying hosted cluster objects For the purposes of this procedure, the following values are used: HostedCluster name: hosted-ipv4 HostedCluster namespace: clusters Disconnected: true Network stack: IPv4 Typically, the HyperShift Operator creates the HostedControlPlane namespace. However, in this case, you want to include all the objects before the HyperShift Operator begins to reconcile the HostedCluster object. Then, when the Operator starts the reconciliation process, it can find all of the objects in place. Create a YAML file with the following information about the namespaces: --- apiVersion: v1 kind: Namespace metadata: creationTimestamp: null name: clusters-hosted-ipv4 spec: {} status: {} --- apiVersion: v1 kind: Namespace metadata: creationTimestamp: null name: clusters spec: {} status: {} Create a YAML file with the following information about the config maps and secrets to include in the HostedCluster deployment: --- apiVersion: v1 data: ca-bundle.crt: | -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- kind: ConfigMap metadata: name: user-ca-bundle namespace: clusters --- apiVersion: v1 data: .dockerconfigjson: xxxxxxxxx kind: Secret metadata: creationTimestamp: null name: hosted-ipv4-pull-secret namespace: clusters --- apiVersion: v1 kind: Secret metadata: name: sshkey-cluster-hosted-ipv4 namespace: clusters stringData: id_rsa.pub: ssh-rsa xxxxxxxxx --- apiVersion: v1 data: key: nTPtVBEt03owkrKhIdmSW8jrWRxU57KO/fnZa8oaG0Y= kind: Secret metadata: creationTimestamp: null name: hosted-ipv4-etcd-encryption-key namespace: clusters type: Opaque Create a YAML file that contains the RBAC roles so that Assisted Service agents can be in the same HostedControlPlane namespace as the hosted control plane and still be managed by the cluster API: apiVersion: rbac.authorization.k8s.io/v1 kind: Role metadata: creationTimestamp: null name: capi-provider-role namespace: clusters-hosted-ipv4 rules: - apiGroups: - agent-install.openshift.io resources: - agents verbs: - '*' Create a YAML file with information about the HostedCluster object, replacing values as necessary: apiVersion: hypershift.openshift.io/v1beta1 kind: HostedCluster metadata: name: hosted-ipv4 namespace: clusters spec: additionalTrustBundle: name: "user-ca-bundle" olmCatalogPlacement: guest imageContentSources: 1 - source: quay.io/openshift-release-dev/ocp-v4.0-art-dev mirrors: - registry.dns.base.domain.name:5000/openshift/release - source: quay.io/openshift-release-dev/ocp-release mirrors: - registry.dns.base.domain.name:5000/openshift/release-images - mirrors: ... ... autoscaling: {} controllerAvailabilityPolicy: SingleReplica dns: baseDomain: dns.base.domain.name etcd: managed: storage: persistentVolume: size: 8Gi restoreSnapshotURL: null type: PersistentVolume managementType: Managed fips: false networking: clusterNetwork: - cidr: 10.132.0.0/14 networkType: OVNKubernetes serviceNetwork: - cidr: 172.31.0.0/16 platform: agent: agentNamespace: clusters-hosted-ipv4 type: Agent pullSecret: name: hosted-ipv4-pull-secret release: image: registry.dns.base.domain.name:5000/openshift/release-images:4.x.y-x86_64 secretEncryption: aescbc: activeKey: name: hosted-ipv4-etcd-encryption-key type: aescbc services: - service: APIServer servicePublishingStrategy: nodePort: address: api.hosted-ipv4.dns.base.domain.name type: NodePort - service: OAuthServer servicePublishingStrategy: nodePort: address: api.hosted-ipv4.dns.base.domain.name type: NodePort - service: OIDC servicePublishingStrategy: nodePort: address: api.hosted-ipv4.dns.base.domain.name type: NodePort - service: Konnectivity servicePublishingStrategy: nodePort: address: api.hosted-ipv4.dns.base.domain.name type: NodePort - service: Ignition servicePublishingStrategy: nodePort: address: api.hosted-ipv4.dns.base.domain.name type: NodePort sshKey: name: sshkey-cluster-hosted-ipv4 status: controlPlaneEndpoint: host: "" port: 0 where dns.base.domain.name is the DNS base domain name and 4.x.y is the supported OpenShift Container Platform version you want to use. 1 The imageContentSources section contains mirror references for user workloads within the hosted cluster. Add an annotation in the HostedCluster object that points to the HyperShift Operator release in the OpenShift Container Platform release: Obtain the image payload by entering the following command: where dns.base.domain.name is the DNS base domain name and 4.x.y is the supported OpenShift Container Platform version you want to use. See the following output: By using the OpenShift Container Platform Images namespace, check the digest by entering the following command: where dns.base.domain.name is the DNS base domain name. See the following output: Note: The release image that is set in the HostedCluster object must use the digest rather than the tag; for example, quay.io/openshift-release-dev/ocp-release@sha256:e3ba11bd1e5e8ea5a0b36a75791c90f29afb0fdbe4125be4e48f69c76a5c47a0 . Create all of the objects that you defined in the YAML files by concatenating them into a file and applying them against the management cluster. To do so, enter the following command: See the output for the hosted control plane: See the output for the hosted cluster: , create a NodePool object. 1.8.12.5.9.2. Creating a NodePool object for the hosted cluster A NodePool is a scalable set of worker nodes that is associated with a hosted cluster. NodePool machine architectures remain consistent within a specific pool and are independent of the machine architecture of the control plane. Create a YAML file with the following information about the NodePool object, replacing values as necessary: apiVersion: hypershift.openshift.io/v1beta1 kind: NodePool metadata: creationTimestamp: null name: hosted-ipv4 namespace: clusters spec: arch: amd64 clusterName: hosted-ipv4 management: autoRepair: false 1 upgradeType: InPlace 2 nodeDrainTimeout: 0s platform: type: Agent release: image: registry.dns.base.domain.name:5000/openshift/release-images:4.x.y-x86_64 3 replicas: 0 status: replicas: 0 4 1 The autoRepair field is set to false because the node will not be re-created if it is removed. 2 The upgradeType is set to InPlace , which indicates that the same bare metal node is reused during an upgrade. 3 All of the nodes included in this NodePool are based on the following OpenShift Container Platform version: 4.x.y-x86_64 . Replace dns.base.domain.name with the DNS base domain name and 4.x.y with the supported OpenShift Container Platform version you want to use. 4 The replicas value is set to 0 so that you can scale them when needed. It is important to keep the NodePool replicas at 0 until all steps are completed. Create the NodePool object by entering the following command: See the output: Replace 4.x.y with the supported OpenShift Container Platform version you want to use. , create an InfraEnv resource. 1.8.12.5.9.3. Creating an InfraEnv resource for the hosted cluster The InfraEnv resource is an Assisted Service object that includes essential details, such as the pullSecretRef and the sshAuthorizedKey . Those details are used to create the Red Hat Enterprise Linux CoreOS (RHCOS) boot image that is customized for the hosted cluster. Create a YAML file with the following information about the InfraEnv resource, replacing values as necessary: --- apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv metadata: name: hosted-ipv4 namespace: clusters-hosted-ipv4 spec: pullSecretRef: 1 name: pull-secret sshAuthorizedKey: ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQDk7ICaUE+/k4zTpxLk4+xFdHi4ZuDi5qjeF52afsNkw0w/glILHhwpL5gnp5WkRuL8GwJuZ1VqLC9EKrdmegn4MrmUlq7WTsP0VFOZFBfq2XRUxo1wrRdor2z0Bbh93ytR+ZsDbbLlGngXaMa0Vbt+z74FqlcajbHTZ6zBmTpBVq5RHtDPgKITdpE1fongp7+ZXQNBlkaavaqv8bnyrP4BWahLP4iO9/xJF9lQYboYwEEDzmnKLMW1VtCE6nJzEgWCufACTbxpNS7GvKtoHT/OVzw8ArEXhZXQUS1UY8zKsX2iXwmyhw5Sj6YboA8WICs4z+TrFP89LmxXY0j6536TQFyRz1iB4WWvCbH5n6W+ABV2e8ssJB1AmEy8QYNwpJQJNpSxzoKBjI73XxvPYYC/IjPFMySwZqrSZCkJYqQ023ySkaQxWZT7in4KeMu7eS2tC+Kn4deJ7KwwUycx8n6RHMeD8Qg9flTHCv3gmab8JKZJqN3hW1D378JuvmIX4V0= 2 1 The pullSecretRef refers to the config map reference in the same namespace as the InfraEnv , where the pull secret is used. 2 The sshAuthorizedKey represents the SSH public key that is placed in the boot image. The SSH key allows access to the worker nodes as the core user. Create the InfraEnv resource by entering the following command: See the following output: , create worker nodes. 1.8.12.5.9.4. Creating worker nodes for the hosted cluster If you are working on a bare metal platform, creating worker nodes is crucial to ensure that the details in the BareMetalHost are correctly configured. If you are working with virtual machines, you can complete the following steps to create empty worker nodes that the Metal3 Operator consumes. To do so, you use kcli . If this is not your first attempt to create worker nodes, you must first delete your setup. To do so, delete the plan by entering the following command: When you are prompted to confirm whether you want to delete the plan, type y . Confirm that you see a message stating that the plan was deleted. Create the virtual machines by entering the following commands: where: start=False means that the virtual machine (VM) will not automatically start upon creation. uefi_legacy=true means that you will use UEFI legacy boot to ensure compatibility with UEFI implementations. plan=hosted-dual indicates the plan name, which identifies a group of machines as a cluster. memory=8192 and numcpus=16 are parameters that specify the resources for the VM, including the RAM and CPU. disks=[200,200] indicates that you are creating two thin-provisioned disks in the VM. nets=[{"name": "dual", "mac": "aa:aa:aa:aa:02:13"}] are network details, including the network name to connect to and the MAC address of the primary interface. restart ksushy restarts the ksushy tool to ensure that the tool detects the VMs that you added. See the resulting output: , create bare metal hosts for the hosted cluster. 1.8.12.5.9.5. Creating bare metal hosts for the hosted cluster A bare metal host is an openshift-machine-api object that encompasses physical and logical details so that it can be identified by a Metal3 Operator. Those details are associated with other Assisted Service objects, known as agents . Important: Before you create the bare metal host and destination nodes, you must create the virtual machines. To create a bare metal host, complete the following steps: Create a YAML file with the following information: Note: Because you have at least one secret that holds the bare metal host credentials, you need to create at least two objects for each worker node. --- apiVersion: v1 kind: Secret metadata: name: hosted-ipv4-worker0-bmc-secret namespace: clusters-hosted-ipv4 data: password: YWRtaW4= username: YWRtaW4= type: Opaque --- apiVersion: metal3.io/v1alpha1 kind: BareMetalHost metadata: name: hosted-ipv4-worker0 namespace: clusters-hosted-ipv4 labels: infraenvs.agent-install.openshift.io: hosted-ipv4 1 annotations: inspect.metal3.io: disabled bmac.agent-install.openshift.io/hostname: hosted-ipv4-worker0 2 spec: automatedCleaningMode: disabled 3 bmc: disableCertificateVerification: true 4 address: redfish-virtualmedia://[192.168.125.1]:9000/redfish/v1/Systems/local/hosted-ipv4-worker0 5 credentialsName: hosted-ipv4-worker0-bmc-secret 6 bootMACAddress: aa:aa:aa:aa:02:11 7 online: true 8 1 infraenvs.agent-install.openshift.io serves as the link between the Assisted Installer and the BareMetalHost objects. 2 bmac.agent-install.openshift.io/hostname represents the node name that is adopted during deployment. 3 automatedCleaningMode prevents the node from being erased by the Metal3 Operator. 4 disableCertificateVerification is set to true to bypass certificate validation from the client. 5 address denotes the baseboard management controller (BMC) address of the worker node. 6 credentialsName points to the secret where the user and password credentials are stored. 7 bootMACAddress indicates the interface MACAddress that the node starts from. 8 online defines the state of the node after the BareMetalHost object is created. Deploy the BareMetalHost object by entering the following command: During the process, you can view the following output: This output indicates that the process is trying to reach the nodes: This output indicates that the nodes are starting: This output indicates that the nodes started successfully: After the nodes start, notice the agents in the namespace, as shown in this example: The agents represent nodes that are available for installation. To assign the nodes to a hosted cluster, scale up the node pool. 1.8.12.5.9.6. Scaling up the node pool After you create the bare metal hosts, their statuses change from Registering to Provisioning to Provisioned . The nodes start with the LiveISO of the agent and a default pod that is named agent . That agent is responsible for receiving instructions from the Assisted Service Operator to install the OpenShift Container Platform payload. To scale up the node pool, enter the following command: After the scaling process is complete, notice that the agents are assigned to a hosted cluster: Also notice that the node pool replicas are set: Replace 4.x.y with the supported OpenShift Container Platform version you want to use. Wait until the nodes join the cluster. During the process, the agents provide updates on their stage and status. , monitor the deployment of the hosted cluster. 1.8.12.5.10. Finishing the hosted cluster deployment for an IPv4 network You can monitor the deployment of a hosted cluster from two perspectives: the control plane and the data plane. 1.8.12.5.10.1. Monitoring the control plane While the hosted cluster is deploying, you can enter the following commands to monitor the control plane: Those commands provide information about the following artifacts: The HyperShift Operator The HostedControlPlane pod The bare metal hosts The agents The InfraEnv resource The HostedCluster and NodePool resources 1.8.12.5.10.2. Monitoring the data plane To monitor how the Operators are progressing during the deployment process, enter the following commands: Those commands provide information about the following artifacts: The cluster version The nodes, specifically, about whether the nodes joined the cluster The cluster Operators 1.8.12.6. Configuring hosted control planes on an IPv6 network The IPv6 network configuration is currently designated as disconnected. The primary reason for this designation is because remote registries do not function with IPv6. The process to configure hosted control planes on an IPv6 network involves the following steps, which are described in detail in the sections that follow: Configure the hypervisor for an IPv6 network Configuring DNS for an IPv6 network Deploying a registry for an IPv6 network Setting up a management cluster for an IPv6 network Configuring the web server for an IPv6 network Configuring image mirroring for an IPv6 network Deploying multicluster engine operator for an IPv6 network Configuring TLS certificates for an IPv6 network Deploying the hosted cluster for an IPv6 network Finishing the deployment for an IPv6 network 1.8.12.6.1. Configuring the hypervisor for an IPv6 network The following information applies to virtual machine environments only. 1.8.12.6.1.1. Accessing and deploying packages for a virtual OpenShift Container Platform cluster To deploy a virtual OpenShift Container Platform management cluster, access the required packages by entering the following command: sudo dnf install dnsmasq radvd vim golang podman bind-utils net-tools httpd-tools tree htop strace tmux -y Enable and start the Podman service by entering the following command: systemctl enable --now podman To use kcli to deploy the OpenShift Container Platform management cluster and other virtual components, install and configure the hypervisor by entering the following commands: sudo yum -y install libvirt libvirt-daemon-driver-qemu qemu-kvm sudo usermod -aG qemu,libvirt USD(id -un) sudo newgrp libvirt sudo systemctl enable --now libvirtd sudo dnf -y copr enable karmab/kcli sudo dnf -y install kcli sudo kcli create pool -p /var/lib/libvirt/images default kcli create host kvm -H 127.0.0.1 local sudo setfacl -m u:USD(id -un):rwx /var/lib/libvirt/images kcli create network -c 192.168.122.0/24 default 1.8.12.6.1.2. Enabling the network manager dispatcher Enable the network manager dispatcher to ensure that virtual machines can resolve the required domains, routes, and registries. To enable the network manager dispatcher, in the /etc/NetworkManager/dispatcher.d/ directory, create a script named forcedns that contains the following content, replacing values as necessary to match your environment: #!/bin/bash export IP="2620:52:0:1306::1" 1 export BASE_RESOLV_CONF="/run/NetworkManager/resolv.conf" if ! [[ `grep -q "USDIP" /etc/resolv.conf` ]]; then export TMP_FILE=USD(mktemp /etc/forcedns_resolv.conf.XXXXXX) cp USDBASE_RESOLV_CONF USDTMP_FILE chmod --reference=USDBASE_RESOLV_CONF USDTMP_FILE sed -i -e "s/dns.base.domain.name//" -e "s/search /& dns.base.domain.name /" -e "0,/nameserver/s/nameserver/& USDIP\n&/" USDTMP_FILE 2 mv USDTMP_FILE /etc/resolv.conf fi echo "ok" 1 Modify the IP variable to point to the IP address of the hypervisor interface that hosts the OpenShift Container Platform management cluster. 2 Replace dns.base.domain.name with the DNS base domain name. After you create the file, add permissions by entering the following command: chmod 755 /etc/NetworkManager/dispatcher.d/forcedns Run the script and verify that the output returns ok . 1.8.12.6.1.3. Configure BMC access Configure ksushy to simulate baseboard management controllers (BMCs) for the virtual machines. Enter the following commands: sudo dnf install python3-pyOpenSSL.noarch python3-cherrypy -y kcli create sushy-service --ssl --ipv6 --port 9000 sudo systemctl daemon-reload systemctl enable --now ksushy Test whether the service is correctly functioning by entering the following command: systemctl status ksushy 1.8.12.6.1.4. Configuring the hypervisor system to allow connections If you are working in a development environment, configure the hypervisor system to allow various types of connections through different virtual networks within the environment. Note: If you are working in a production environment, you must establish proper rules for the firewalld service and configure SELinux policies to maintain a secure environment. For SELinux, enter the following command: sed -i s/^SELINUX=.*USD/SELINUX=permissive/ /etc/selinux/config; setenforce 0 For firewalld , enter the following command: systemctl disable --now firewalld For libvirtd , enter the following commands: systemctl restart libvirtd systemctl enable --now libvirtd , configure DNS for your environment. 1.8.12.6.1.5. Additional resources For more information about kcli , see the official kcli documentation . 1.8.12.6.2. Configuring DNS for an IPv6 network This step is mandatory for both disconnected and connected environments in both virtual and bare metal environments. The key distinction between virtual and bare metal environment lies in the location where you configure the resources. In a bare-metal environment, use a solution like Bind rather than a lightweight solution like dnsmasq . To configure DNS for an IPv6 network on a virtual environment, see Default ingress and DNS behavior . To configure DNS for an IPv6 network on bare metal, see Configuring DNS on bare metal . , deploy a registry. 1.8.12.6.3. Deploying a registry for an IPv6 network For development environments, deploy a small, self-hosted registry by using a Podman container. For production environments, use an enterprise-hosted registry, such as Red Hat Quay, Nexus, or Artifactory. To deploy a small registry by using Podman, complete the following steps: As a privileged user, access the USD{HOME} directory and create the following script: #!/usr/bin/env bash set -euo pipefail PRIMARY_NIC=USD(ls -1 /sys/class/net | grep -v podman | head -1) export PATH=/root/bin:USDPATH export PULL_SECRET="/root/baremetal/hub/openshift_pull.json" 1 if [[ ! -f USDPULL_SECRET ]];then echo "Pull Secret not found, exiting..." exit 1 fi dnf -y install podman httpd httpd-tools jq skopeo libseccomp-devel export IP=USD(ip -o addr show USDPRIMARY_NIC | head -1 | awk '{print USD4}' | cut -d'/' -f1) REGISTRY_NAME=registry.USD(hostname --long) REGISTRY_USER=dummy REGISTRY_PASSWORD=dummy KEY=USD(echo -n USDREGISTRY_USER:USDREGISTRY_PASSWORD | base64) echo "{\"auths\": {\"USDREGISTRY_NAME:5000\": {\"auth\": \"USDKEY\", \"email\": \"sample-email@domain.ltd\"}}}" > /root/disconnected_pull.json mv USD{PULL_SECRET} /root/openshift_pull.json.old jq ".auths += {\"USDREGISTRY_NAME:5000\": {\"auth\": \"USDKEY\",\"email\": \"sample-email@domain.ltd\"}}" < /root/openshift_pull.json.old > USDPULL_SECRET mkdir -p /opt/registry/{auth,certs,data,conf} cat <<EOF > /opt/registry/conf/config.yml version: 0.1 log: fields: service: registry storage: cache: blobdescriptor: inmemory filesystem: rootdirectory: /var/lib/registry delete: enabled: true http: addr: :5000 headers: X-Content-Type-Options: [nosniff] health: storagedriver: enabled: true interval: 10s threshold: 3 compatibility: schema1: enabled: true EOF openssl req -newkey rsa:4096 -nodes -sha256 -keyout /opt/registry/certs/domain.key -x509 -days 3650 -out /opt/registry/certs/domain.crt -subj "/C=US/ST=Madrid/L=San Bernardo/O=Karmalabs/OU=Guitar/CN=USDREGISTRY_NAME" -addext "subjectAltName=DNS:USDREGISTRY_NAME" cp /opt/registry/certs/domain.crt /etc/pki/ca-trust/source/anchors/ update-ca-trust extract htpasswd -bBc /opt/registry/auth/htpasswd USDREGISTRY_USER USDREGISTRY_PASSWORD podman create --name registry --net host --security-opt label=disable --replace -v /opt/registry/data:/var/lib/registry:z -v /opt/registry/auth:/auth:z -v /opt/registry/conf/config.yml:/etc/docker/registry/config.yml -e "REGISTRY_AUTH=htpasswd" -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry" -e "REGISTRY_HTTP_SECRET=ALongRandomSecretForRegistry" -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd -v /opt/registry/certs:/certs:z -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key docker.io/library/registry:latest [ "USD?" == "0" ] || !! systemctl enable --now registry 1 Replace the location of the PULL_SECRET with the appropriate location for your setup. Name the script file registry.sh and save it. When you run the script, it pulls in the following information: The registry name, based on the hypervisor hostname The necessary credentials and user access details Adjust permissions by adding the execution flag as follows: To run the script without any parameters, enter the following command: The script starts the server. The script uses a systemd service for management purposes. If you need to manage the script, you can use the following commands: The root folder for the registry is in the /opt/registry directory and contains the following subdirectories: certs contains the TLS certificates. auth contains the credentials. data contains the registry images. conf contains the registry configuration. 1.8.12.6.4. Setting up the management cluster for an IPv6 network To set up an OpenShift Container Platform management cluster, you can use dev-scripts, or if you are based on virtual machines, you can use the kcli tool. The following instructions are specific to the kcli tool. Ensure that the right networks are prepared for use in the hypervisor. The networks will host both the management and hosted clusters. Enter the following kcli command: where: -c specifies the CIDR for the network. -P dhcp=false configures the network to disable the DHCP, which is handled by the dnsmasq that you configured. -P dns=false configures the network to disable the DNS, which is also handled by the dnsmasq that you configured. --domain sets the domain to search. dns.base.domain.name is the DNS base domain name. ipv6 is the name of the network that you are creating. After the network is created, review the following output: Ensure that the pull secret and kcli plan files are in place so that you can deploy the OpenShift Container Platform management cluster: Confirm that the pull secret is in the same folder as the kcli plan, and that the pull secret file is named openshift_pull.json . Add the kcli plan, which contains the OpenShift Container Platform definition, in the mgmt-compact-hub-ipv6.yaml file. Ensure that you update the file contents to match your environment: plan: hub-ipv6 force: true version: nightly tag: "4.x.y-x86_64" cluster: "hub-ipv6" ipv6: true domain: dns.base.domain.name api_ip: 2620:52:0:1305::2 ingress_ip: 2620:52:0:1305::3 disconnected_url: registry.dns.base.domain.name:5000 disconnected_update: true disconnected_user: dummy disconnected_password: dummy disconnected_operators_version: v4.14 disconnected_operators: - name: metallb-operator - name: lvms-operator channels: - name: stable-4.14 disconnected_extra_images: - quay.io/user-name/trbsht:latest - quay.io/user-name/hypershift:BMSelfManage-v4.14-rc-v3 - registry.redhat.io/openshift4/ose-kube-rbac-proxy:v4.10 dualstack: false disk_size: 200 extra_disks: [200] memory: 48000 numcpus: 16 ctlplanes: 3 workers: 0 manifests: extra-manifests metal3: true network: ipv6 users_dev: developer users_devpassword: developer users_admin: admin users_adminpassword: admin metallb_pool: ipv6-virtual-network metallb_ranges: - 2620:52:0:1305::150-2620:52:0:1305::190 metallb_autoassign: true apps: - users - lvms-operator - metallb-operator vmrules: - hub-bootstrap: nets: - name: ipv6 mac: aa:aa:aa:aa:03:10 - hub-ctlplane-0: nets: - name: ipv6 mac: aa:aa:aa:aa:03:01 - hub-ctlplane-1: nets: - name: ipv6 mac: aa:aa:aa:aa:03:02 - hub-ctlplane-2: nets: - name: ipv6 mac: aa:aa:aa:aa:03:03 To provision the management cluster, enter the following command: 1.8.12.6.4.1. Additional resources For more information about the parameters in the kcli plan file, see Create a parameters.yml in the official kcli documentation. 1.8.12.6.5. Configuring the web server for an IPv6 network You need to configure an additional web server to host the Red Hat Enterprise Linux CoreOS (RHCOS) images that are associated with the OpenShift Container Platform release that you are deploying as a hosted cluster. To configure the web server, complete the following steps: Extract the openshift-install binary from the OpenShift Container Platform release that you want to use by entering the following command: oc adm -a USD{LOCAL_SECRET_JSON} release extract --command=openshift-install "USD{LOCAL_REGISTRY}/USD{LOCAL_REPOSITORY}:USD{OCP_RELEASE}-USD{ARCHITECTURE}" Run the following script. The script creates a folder in the /opt/srv directory. The folder contains the RHCOS images to provision the worker nodes. #!/bin/bash WEBSRV_FOLDER=/opt/srv ROOTFS_IMG_URL="USD(./openshift-install coreos print-stream-json | jq -r '.architectures.x86_64.artifacts.metal.formats.pxe.rootfs.location')" 1 LIVE_ISO_URL="USD(./openshift-install coreos print-stream-json | jq -r '.architectures.x86_64.artifacts.metal.formats.iso.disk.location')" 2 mkdir -p USD{WEBSRV_FOLDER}/images curl -Lk USD{ROOTFS_IMG_URL} -o USD{WEBSRV_FOLDER}/images/USD{ROOTFS_IMG_URL##*/} curl -Lk USD{LIVE_ISO_URL} -o USD{WEBSRV_FOLDER}/images/USD{LIVE_ISO_URL##*/} chmod -R 755 USD{WEBSRV_FOLDER}/* ## Run Webserver podman ps --noheading | grep -q websrv-ai if [[ USD? == 0 ]];then echo "Launching Registry pod..." /usr/bin/podman run --name websrv-ai --net host -v /opt/srv:/usr/local/apache2/htdocs:z quay.io/alosadag/httpd:p8080 fi 1 You can find the ROOTFS_IMG_URL value on the OpenShift CI Release page. 2 You can find the LIVE_ISO_URL value on the OpenShift CI Release page. After the download is completed, a container runs to host the images on a web server. The container uses a variation of the official HTTPd image, which also enables it to work with IPv6 networks. 1.8.12.6.6. Configuring image mirroring for an IPv6 network Image mirroring is the process of fetching images from external registries, such as registry.redhat.com or quay.io , and storing them in your private registry. 1.8.12.6.6.1. Completing the mirroring process Note: Start the mirroring process after the registry server is running. In the following procedures, the oc-mirror tool is used, which is a binary that uses the ImageSetConfiguration object. In the file, you can specify the following information: The OpenShift Container Platform versions to mirror. The versions are in quay.io . The additional Operators to mirror. Select packages individually. The extra images that you want to add to the repository. To configure image mirroring, complete the following steps: Ensure that your USD{HOME}/.docker/config.json file is updated with the registries that you are going to mirror from and with the private registry that you plan to push the images to. By using the following example, create an ImageSetConfiguration object to use for mirroring. Replace values as needed to match your environment: 1 Replace dns.base.domain.name with the DNS base domain name and 4.x.y with the supported OpenShift Container Platform version you want to use. Start the mirroring process by entering the following command: After the mirroring process is finished, you have a new folder named oc-mirror-workspace/results-XXXXXX/ , which contains the ICSP and the catalog sources to apply on the hosted cluster. Mirror the nightly or CI versions of OpenShift Container Platform by using the oc adm release mirror command. Enter the following command: Replace 4.x.y with the supported OpenShift Container Platform version you want to use. Mirror the latest multicluster engine operator images by following the steps in Install on disconnected networks . 1.8.12.6.6.2. Applying objects in the management cluster After the mirroring process is complete, you need to apply two objects in the management cluster: Image Content Source Policies (ICSP) or Image Digest Mirror Set (IDMS) Catalog sources When you use the oc-mirror tool, the output artifacts are in a folder named oc-mirror-workspace/results-XXXXXX/ . ICSP or IDMS initiates a MachineConfig change that does not restart your nodes but restarts the kubelet on each of them. After the nodes are marked as READY , you need to apply the newly generated catalog sources. The catalog sources initiate actions in the openshift-marketplace Operator, such as downloading the catalog image and processing it to retrieve all the PackageManifests that are included in that image. To check the new sources, run the following command by using the new CatalogSource as a source: To apply the artifacts, complete the following steps: Create the ICSP or IDMS artifacts by entering the following command: Wait for the nodes to become ready, and then enter the following command: 1.8.12.6.6.3. Additional resources If you are working in a virtual environment, after you configure mirroring, ensure that you meet the prerequisites for hosted control planes on OpenShift Virtualization . For more information about mirroring nightly or CI versions of OpenShift Container Platform, see Mirroring images for a disconnected installation using the oc-mirror plugin . 1.8.12.6.7. Deploying multicluster engine operator for an IPv6 network The multicluster engine operator plays a crucial role in deploying clusters across providers. If you already installed Red Hat Advanced Cluster Management, you do not need to install multicluster engine operator because it is automatically installed. If you do not have multicluster engine operator installed, review the following documentation to understand the prerequisites and steps to install it: About cluster lifecycle with multicluster engine operator Installing and upgrading multicluster engine operator 1.8.12.6.7.1. Deploying AgentServiceConfig resources The AgentServiceConfig custom resource is an essential component of the Assisted Service add-on that is part of multicluster engine operator. It is responsible for bare metal cluster deployment. When the add-on is enabled, you deploy the AgentServiceConfig resource to configure the add-on. In addition to configuring the AgentServiceConfig resource, you need to include additional config maps to ensure that multicluster engine operator functions properly in a disconnected environment. Configure the custom registries by adding the following config map, which contains the disconnected details to customize the deployment: --- apiVersion: v1 kind: ConfigMap metadata: name: custom-registries namespace: multicluster-engine labels: app: assisted-service data: ca-bundle.crt: | -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- registries.conf: | unqualified-search-registries = ["registry.access.redhat.com", "docker.io"] [[registry]] prefix = "" location = "registry.redhat.io/openshift4" mirror-by-digest-only = true [[registry.mirror]] location = "registry.dns.base.domain.name:5000/openshift4" 1 [[registry]] prefix = "" location = "registry.redhat.io/rhacm2" mirror-by-digest-only = true ... ... 1 Replace dns.base.domain.name with the DNS base domain name. The object contains two fields: Custom CAs: This field contains the Certificate Authorities (CAs) that are loaded into the various processes of the deployment. Registries: The Registries.conf field contains information about images and namespaces that need to be consumed from a mirror registry rather than the original source registry. Configure the Assisted Service by adding the AssistedServiceConfig object, as shown in the following example: --- apiVersion: agent-install.openshift.io/v1beta1 kind: AgentServiceConfig metadata: annotations: unsupported.agent-install.openshift.io/assisted-service-configmap: assisted-service-config 1 name: agent namespace: multicluster-engine spec: mirrorRegistryRef: name: custom-registries 2 databaseStorage: storageClassName: lvms-vg1 accessModes: - ReadWriteOnce resources: requests: storage: 10Gi filesystemStorage: storageClassName: lvms-vg1 accessModes: - ReadWriteOnce resources: requests: storage: 20Gi osImages: 3 - cpuArchitecture: x86_64 openshiftVersion: "4.14" rootFSUrl: http://registry.dns.base.domain.name:8080/images/rhcos-414.92.202308281054-0-live-rootfs.x86_64.img 4 url: http://registry.dns.base.domain.name:8080/images/rhcos-414.92.202308281054-0-live.x86_64.iso version: 414.92.202308281054-0 1 The metadata.annotations["unsupported.agent-install.openshift.io/assisted-service-configmap"] annotation references the config map name that the Operator consumes to customize behavior. 2 The spec.mirrorRegistryRef.name annotation points to the config map that contains disconnected registry information that the Assisted Service Operator consumes. This config map adds those resources during the deployment process. 3 The spec.osImages field contains different versions available for deployment by this Operator. This field is mandatory. This example assumes that you already downloaded the RootFS and LiveISO files. 4 In the rootFSUrl and url fields, replace dns.base.domain.name with the DNS base domain name. Deploy all of the objects by concatenating them into a single file and applying them to the management cluster. To do so, enter the following command: The command triggers two pods, as shown in this example output: 1 The assisted-image-service pod is responsible for creating the Red Hat Enterprise Linux CoreOS (RHCOS) boot image template, which is customized for each cluster that you deploy. 2 The assisted-service refers to the Operator. 1.8.12.6.8. Configuring TLS certificates for an IPv6 network Several TLS certificates are involved in the process to configure hosted control planes in a disconnected environment. To add a Certificate Authority (CA) to the management cluster, you need to modify the content of the following files in the OpenShift Container Platform control plane and worker nodes: /etc/pki/ca-trust/extracted/pem/ /etc/pki/ca-trust/source/anchors /etc/pki/tls/certs/ To add a CA to the management cluster, complete the following steps: Complete the steps in Updating the CA bundle in the official OpenShift Container Platform documentation. That method involves using the image-registry-operator , which deploys the CAs to the OpenShift Container Platform nodes. If that method does not apply to your situation, check whether the openshift-config namespace in the management cluster contains a config map named user-ca-bundle . If the namespace contains that config map, enter the following command: If the namespace does not contain that config map, enter the following command: 1.8.12.6.9. Deploying the hosted cluster for an IPv6 network A hosted cluster is an OpenShift Container Platform cluster with its control plane and API endpoint hosted on a management cluster. The hosted cluster includes the control plane and its corresponding data plane. Although you can use the console in Red Hat Advanced Cluster Management to create a hosted cluster, the following procedures use manifests, which provide more flexibility for modifying the related artifacts. 1.8.12.6.9.1. Deploying hosted cluster objects For the purposes of this procedure, the following values are used: HostedCluster name: hosted-ipv6 HostedCluster namespace: clusters Disconnected: true Network stack: IPv6 Typically, the HyperShift Operator creates the HostedControlPlane namespace. However, in this case, you want to include all the objects before the HyperShift Operator begins to reconcile the HostedCluster object. Then, when the Operator starts the reconciliation process, it can find all of the objects in place. Create a YAML file with the following information about the namespaces: --- apiVersion: v1 kind: Namespace metadata: creationTimestamp: null name: clusters-hosted-ipv6 spec: {} status: {} --- apiVersion: v1 kind: Namespace metadata: creationTimestamp: null name: clusters spec: {} status: {} Create a YAML file with the following information about the config maps and secrets to include in the HostedCluster deployment: --- apiVersion: v1 data: ca-bundle.crt: | -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- kind: ConfigMap metadata: name: user-ca-bundle namespace: clusters --- apiVersion: v1 data: .dockerconfigjson: xxxxxxxxx kind: Secret metadata: creationTimestamp: null name: hosted-ipv6-pull-secret namespace: clusters --- apiVersion: v1 kind: Secret metadata: name: sshkey-cluster-hosted-ipv6 namespace: clusters stringData: id_rsa.pub: ssh-rsa xxxxxxxxx --- apiVersion: v1 data: key: nTPtVBEt03owkrKhIdmSW8jrWRxU57KO/fnZa8oaG0Y= kind: Secret metadata: creationTimestamp: null name: hosted-ipv6-etcd-encryption-key namespace: clusters type: Opaque Create a YAML file that contains the RBAC roles so that Assisted Service agents can be in the same HostedControlPlane namespace as the hosted control plane and still be managed by the cluster API: apiVersion: rbac.authorization.k8s.io/v1 kind: Role metadata: creationTimestamp: null name: capi-provider-role namespace: clusters-hosted-ipv6 rules: - apiGroups: - agent-install.openshift.io resources: - agents verbs: - '*' Create a YAML file with information about the HostedCluster object, replacing values as necessary: apiVersion: hypershift.openshift.io/v1beta1 kind: HostedCluster metadata: name: hosted-ipv6 namespace: clusters annotations: hypershift.openshift.io/control-plane-operator-image: registry.ocp-edge-cluster-0.qe.lab.redhat.com:5005/openshift/release@sha256:31149e3e5f8c5e5b5b100ff2d89975cf5f7a73801b2c06c639bf6648766117f8 spec: additionalTrustBundle: name: "user-ca-bundle" olmCatalogPlacement: guest imageContentSources: 1 - source: quay.io/openshift-release-dev/ocp-v4.0-art-dev mirrors: - registry.dns.base.domain.name:5000/openshift/release - source: quay.io/openshift-release-dev/ocp-release mirrors: - registry.dns.base.domain.name:5000/openshift/release-images - mirrors: ... ... autoscaling: {} controllerAvailabilityPolicy: SingleReplica dns: baseDomain: dns.base.domain.name etcd: managed: storage: persistentVolume: size: 8Gi restoreSnapshotURL: null type: PersistentVolume managementType: Managed fips: false networking: clusterNetwork: - cidr: 10.132.0.0/14 networkType: OVNKubernetes serviceNetwork: - cidr: 172.31.0.0/16 platform: agent: agentNamespace: clusters-hosted-ipv6 type: Agent pullSecret: name: hosted-ipv6-pull-secret release: image: registry.dns.base.domain.name:5000/openshift/release-images:4.x.y-x86_64 secretEncryption: aescbc: activeKey: name: hosted-ipv6-etcd-encryption-key type: aescbc services: - service: APIServer servicePublishingStrategy: nodePort: address: api.hosted-ipv6.dns.base.domain.name type: NodePort - service: OAuthServer servicePublishingStrategy: nodePort: address: api.hosted-ipv6.dns.base.domain.name type: NodePort - service: OIDC servicePublishingStrategy: nodePort: address: api.hosted-ipv6.dns.base.domain.name type: NodePort - service: Konnectivity servicePublishingStrategy: nodePort: address: api.hosted-ipv6.dns.base.domain.name type: NodePort - service: Ignition servicePublishingStrategy: nodePort: address: api.hosted-ipv6.dns.base.domain.name type: NodePort sshKey: name: sshkey-cluster-hosted-ipv6 status: controlPlaneEndpoint: host: "" port: 0 where dns.base.domain.name is the DNS base domain name and 4.x.y is the supported OpenShift Container Platform version you want to use. 1 The imageContentSources section contains mirror references for user workloads within the hosted cluster. Add an annotation in the HostedCluster object that points to the HyperShift Operator release in the OpenShift Container Platform release: Obtain the image payload by entering the following command: where dns.base.domain.name is the DNS base domain name and 4.x.y is the supported OpenShift Container Platform version you want to use. See the following output: By using the OpenShift Container Platform Images namespace, check the digest by entering the following command: where dns.base.domain.name is the DNS base domain name. See the following output: Note: The release image that is set in the HostedCluster object must use the digest rather than the tag; for example, quay.io/openshift-release-dev/ocp-release@sha256:e3ba11bd1e5e8ea5a0b36a75791c90f29afb0fdbe4125be4e48f69c76a5c47a0 . Create all of the objects that you defined in the YAML files by concatenating them into a file and applying them against the management cluster. To do so, enter the following command: See the output for the hosted control plane: See the output for the hosted cluster: , create a NodePool object. 1.8.12.6.9.2. Creating a NodePool object for the hosted cluster A NodePool is a scalable set of worker nodes that is associated with a hosted cluster. NodePool machine architectures remain consistent within a specific pool and are independent of the machine architecture of the control plane. Create a YAML file with the following information about the NodePool object, replacing values as necessary: apiVersion: hypershift.openshift.io/v1beta1 kind: NodePool metadata: creationTimestamp: null name: hosted-ipv6 namespace: clusters spec: arch: amd64 clusterName: hosted-ipv6 management: autoRepair: false 1 upgradeType: InPlace 2 nodeDrainTimeout: 0s platform: type: Agent release: image: registry.dns.base.domain.name:5000/openshift/release-images:4.x.y-x86_64 3 replicas: 0 status: replicas: 0 4 1 The autoRepair field is set to false because the node will not be re-created if it is removed. 2 The upgradeType is set to InPlace , which indicates that the same bare metal node is reused during an upgrade. 3 All of the nodes included in this NodePool are based on the following OpenShift Container Platform version: 4.x.y-x86_64 . Replace dns.base.domain.name with the DNS base domain name and 4.x.y with the supported OpenShift Container Platform version you want to use. 4 The replicas value is set to 0 so that you can scale them when needed. It is important to keep the NodePool replicas at 0 until all steps are completed. Create the NodePool object by entering the following command: See the output: , create an InfraEnv resource. 1.8.12.6.9.3. Creating an InfraEnv resource for the hosted cluster The InfraEnv resource is an Assisted Service object that includes essential details, such as the pullSecretRef and the sshAuthorizedKey . Those details are used to create the Red Hat Enterprise Linux CoreOS (RHCOS) boot image that is customized for the hosted cluster. Create a YAML file with the following information about the InfraEnv resource, replacing values as necessary: --- apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv metadata: name: hosted-ipv6 namespace: clusters-hosted-ipv6 spec: pullSecretRef: 1 name: pull-secret sshAuthorizedKey: ssh-rsa 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 2 1 The pullSecretRef refers to the config map reference in the same namespace as the InfraEnv , where the pull secret is used. 2 The sshAuthorizedKey represents the SSH public key that is placed in the boot image. The SSH key allows access to the worker nodes as the core user. Create the InfraEnv resource by entering the following command: See the following output: , create worker nodes. 1.8.12.6.9.4. Creating worker nodes for the hosted cluster If you are working on a bare metal platform, creating worker nodes is crucial to ensure that the details in the BareMetalHost are correctly configured. If you are working with virtual machines, you can complete the following steps to create empty worker nodes that the Metal3 Operator consumes. To do so, you use the kcli tool. If this is not your first attempt to create worker nodes, you must first delete your setup. To do so, delete the plan by entering the following command: When you are prompted to confirm whether you want to delete the plan, type y . Confirm that you see a message stating that the plan was deleted. Create the virtual machines by entering the following commands: where: start=False means that the virtual machine (VM) will not automatically start upon creation. uefi_legacy=true means that you will use UEFI legacy boot to ensure compatibility with UEFI implementations. plan=hosted-dual indicates the plan name, which identifies a group of machines as a cluster. memory=8192 and numcpus=16 are parameters that specify the resources for the VM, including the RAM and CPU. disks=[200,200] indicates that you are creating two thin-provisioned disks in the VM. nets=[{"name": "dual", "mac": "aa:aa:aa:aa:02:13"}] are network details, including the network name to connect to and the MAC address of the primary interface. restart ksushy restarts the ksushy tool to ensure that the tool detects the VMs that you added. See the resulting output: , create bare metal hosts for the hosted cluster. 1.8.12.6.9.5. Creating bare metal hosts for the hosted cluster A bare metal host is an openshift-machine-api object that encompasses physical and logical details so that it can be identified by a Metal3 Operator. Those details are associated with other Assisted Service objects, known as agents . Important: Before you create the bare metal host and destination nodes, you must create the virtual machines. To create a bare metal host, complete the following steps: Create a YAML file with the following information: Note: Because you have at least one secret that holds the bare metal host credentials, you need to create at least two objects for each worker node. --- apiVersion: v1 kind: Secret metadata: name: hosted-ipv6-worker0-bmc-secret namespace: clusters-hosted-ipv6 data: password: YWRtaW4= username: YWRtaW4= type: Opaque --- apiVersion: metal3.io/v1alpha1 kind: BareMetalHost metadata: name: hosted-ipv6-worker0 namespace: clusters-hosted-ipv6 labels: infraenvs.agent-install.openshift.io: hosted-ipv6 1 annotations: inspect.metal3.io: disabled bmac.agent-install.openshift.io/hostname: hosted-ipv6-worker0 2 spec: automatedCleaningMode: disabled 3 bmc: disableCertificateVerification: true 4 address: redfish-virtualmedia://[192.168.125.1]:9000/redfish/v1/Systems/local/hosted-ipv6-worker0 5 credentialsName: hosted-ipv6-worker0-bmc-secret 6 bootMACAddress: aa:aa:aa:aa:03:11 7 online: true 8 1 infraenvs.agent-install.openshift.io serves as the link between the Assisted Installer and the BareMetalHost objects. 2 bmac.agent-install.openshift.io/hostname represents the node name that is adopted during deployment. 3 automatedCleaningMode prevents the node from being erased by the Metal3 Operator. 4 disableCertificateVerification is set to true to bypass certificate validation from the client. 5 address denotes the baseboard management controller (BMC) address of the worker node. 6 credentialsName points to the secret where the user and password credentials are stored. 7 bootMACAddress indicates the interface MAC address that the node starts from. 8 online defines the state of the node after the BareMetalHost object is created. Deploy the BareMetalHost object by entering the following command: During the process, you can view the following output: This output indicates that the process is trying to reach the nodes: This output indicates that the nodes are starting: This output indicates that the nodes started successfully: After the nodes start, notice the agents in the namespace, as shown in this example: The agents represent nodes that are available for installation. To assign the nodes to a hosted cluster, scale up the node pool. 1.8.12.6.9.6. Scaling up the node pool After you create the bare metal hosts, their statuses change from Registering to Provisioning to Provisioned . The nodes start with the LiveISO of the agent and a default pod that is named agent . That agent is responsible for receiving instructions from the Assisted Service Operator to install the OpenShift Container Platform payload. To scale up the node pool, enter the following command: After the scaling process is complete, notice that the agents are assigned to a hosted cluster: Also notice that the node pool replicas are set: Wait until the nodes join the cluster. During the process, the agents provide updates on their stage and status. , monitor the deployment of the hosted cluster. 1.8.12.6.10. Finishing the hosted cluster deployment for an IPv6 network You can monitor the deployment of a hosted cluster from two perspectives: the control plane and the data plane. 1.8.12.6.10.1. Monitoring the control plane While the hosted cluster is deploying, you can enter the following commands to monitor the control plane: Those commands provide information about the following artifacts: The HyperShift Operator The HostedControlPlane pod The bare metal hosts The agents The InfraEnv resource The HostedCluster and NodePool resources 1.8.12.6.10.2. Monitoring the data plane To monitor how the Operators are progressing during the deployment process, enter the following commands: Those commands provide information about the following artifacts: The cluster version The nodes, specifically, about whether the nodes joined the cluster The cluster Operators 1.8.12.7. Configuring hosted control planes on a dual stack network (Technology Preview) The dual-stack network configuration is currently designated as disconnected. The primary reason for this designation is because remote registries do not function with IPv6. The process to configure hosted control planes on a dual-stack network involves the following steps, which are described in detail in the sections that follow: Configure the hypervisor for a dual-stack network Configuring DNS for a dual-stack network Deploying a registry for a dual-stack network Setting up a management cluster for a dual-stack network Configuring the web server for a dual-stack network Configuring image mirroring for a dual-stack network Deploying multicluster engine operator for a dual-stack network Configuring TLS certificates for a dual-stack network Deploying the hosted cluster for a dual-stack network Finishing the deployment for a dual-stack network 1.8.12.7.1. Configuring the hypervisor for a dual stack network The following information applies to virtual machine environments only. 1.8.12.7.1.1. Accessing and deploying packages for a virtual OpenShift Container Platform cluster To deploy a virtual OpenShift Container Platform management cluster, access the required packages by entering the following command: sudo dnf install dnsmasq radvd vim golang podman bind-utils net-tools httpd-tools tree htop strace tmux -y Enable and start the Podman service by entering the following command: systemctl enable --now podman To use kcli to deploy the OpenShift Container Platform management cluster and other virtual components, install and configure the hypervisor by entering the following commands: sudo yum -y install libvirt libvirt-daemon-driver-qemu qemu-kvm sudo usermod -aG qemu,libvirt USD(id -un) sudo newgrp libvirt sudo systemctl enable --now libvirtd sudo dnf -y copr enable karmab/kcli sudo dnf -y install kcli sudo kcli create pool -p /var/lib/libvirt/images default kcli create host kvm -H 127.0.0.1 local sudo setfacl -m u:USD(id -un):rwx /var/lib/libvirt/images kcli create network -c 192.168.122.0/24 default 1.8.12.7.1.2. Enabling the network manager dispatcher Enable the network manager dispatcher to ensure that virtual machines can resolve the required domains, routes, and registries. To enable the network manager dispatcher, in the /etc/NetworkManager/dispatcher.d/ directory, create a script named forcedns that contains the following content, replacing values as necessary to match your environment: #!/bin/bash export IP="192.168.126.1" 1 export BASE_RESOLV_CONF="/run/NetworkManager/resolv.conf" if ! [[ `grep -q "USDIP" /etc/resolv.conf` ]]; then export TMP_FILE=USD(mktemp /etc/forcedns_resolv.conf.XXXXXX) cp USDBASE_RESOLV_CONF USDTMP_FILE chmod --reference=USDBASE_RESOLV_CONF USDTMP_FILE sed -i -e "s/dns.base.domain.name//" -e "s/search /& dns.base.domain.name /" -e "0,/nameserver/s/nameserver/& USDIP\n&/" USDTMP_FILE 2 mv USDTMP_FILE /etc/resolv.conf fi echo "ok" 1 Modify the IP variable to point to the IP address of the hypervisor interface that hosts the OpenShift Container Platform management cluster. 2 Replace dns.base.domain.name with the DNS base domain name. After you create the file, add permissions by entering the following command: chmod 755 /etc/NetworkManager/dispatcher.d/forcedns Run the script and verify that the output returns ok . 1.8.12.7.1.3. Configure BMC access Configure ksushy to simulate baseboard management controllers (BMCs) for the virtual machines. Enter the following commands: sudo dnf install python3-pyOpenSSL.noarch python3-cherrypy -y kcli create sushy-service --ssl --ipv6 --port 9000 sudo systemctl daemon-reload systemctl enable --now ksushy Test whether the service is correctly functioning by entering the following command: systemctl status ksushy 1.8.12.7.1.4. Configuring the hypervisor system to allow connections If you are working in a development environment, configure the hypervisor system to allow various types of connections through different virtual networks within the environment. Note: If you are working in a production environment, you must establish proper rules for the firewalld service and configure SELinux policies to maintain a secure environment. For SELinux, enter the following command: sed -i s/^SELINUX=.*USD/SELINUX=permissive/ /etc/selinux/config; setenforce 0 For firewalld , enter the following command: systemctl disable --now firewalld For libvirtd , enter the following commands: systemctl restart libvirtd systemctl enable --now libvirtd , configure DNS for your environment. 1.8.12.7.1.5. Additional resources For more information about kcli , see the official kcli documentation . 1.8.12.7.2. Configuring DNS for a dual stack network This step is mandatory for both disconnected and connected environments in both virtual and bare metal environments. The key distinction between virtual and bare metal environment lies in the location where you configure the resources. In a non-virtual environment, use a solution like Bind rather than a lightweight solution like dnsmasq . To configure DNS for a dual stack network on a virtual environment, see Default ingress and DNS behavior . To configure DNS for a dual stack network on bare metal, see Configuring DNS on bare metal . , deploy a registry. 1.8.12.7.3. Deploying a registry for a dual stack network For development environments, deploy a small, self-hosted registry by using a Podman container. For production environments, deploy an enterprise-hosted registry, such as Red Hat Quay, Nexus, or Artifactory. To deploy a small registry by using Podman, complete the following steps: As a privileged user, access the USD{HOME} directory and create the following script: #!/usr/bin/env bash set -euo pipefail PRIMARY_NIC=USD(ls -1 /sys/class/net | grep -v podman | head -1) export PATH=/root/bin:USDPATH export PULL_SECRET="/root/baremetal/hub/openshift_pull.json" 1 if [[ ! -f USDPULL_SECRET ]];then echo "Pull Secret not found, exiting..." exit 1 fi dnf -y install podman httpd httpd-tools jq skopeo libseccomp-devel export IP=USD(ip -o addr show USDPRIMARY_NIC | head -1 | awk '{print USD4}' | cut -d'/' -f1) REGISTRY_NAME=registry.USD(hostname --long) REGISTRY_USER=dummy REGISTRY_PASSWORD=dummy KEY=USD(echo -n USDREGISTRY_USER:USDREGISTRY_PASSWORD | base64) echo "{\"auths\": {\"USDREGISTRY_NAME:5000\": {\"auth\": \"USDKEY\", \"email\": \"sample-email@domain.ltd\"}}}" > /root/disconnected_pull.json mv USD{PULL_SECRET} /root/openshift_pull.json.old jq ".auths += {\"USDREGISTRY_NAME:5000\": {\"auth\": \"USDKEY\",\"email\": \"sample-email@domain.ltd\"}}" < /root/openshift_pull.json.old > USDPULL_SECRET mkdir -p /opt/registry/{auth,certs,data,conf} cat <<EOF > /opt/registry/conf/config.yml version: 0.1 log: fields: service: registry storage: cache: blobdescriptor: inmemory filesystem: rootdirectory: /var/lib/registry delete: enabled: true http: addr: :5000 headers: X-Content-Type-Options: [nosniff] health: storagedriver: enabled: true interval: 10s threshold: 3 compatibility: schema1: enabled: true EOF openssl req -newkey rsa:4096 -nodes -sha256 -keyout /opt/registry/certs/domain.key -x509 -days 3650 -out /opt/registry/certs/domain.crt -subj "/C=US/ST=Madrid/L=San Bernardo/O=Karmalabs/OU=Guitar/CN=USDREGISTRY_NAME" -addext "subjectAltName=DNS:USDREGISTRY_NAME" cp /opt/registry/certs/domain.crt /etc/pki/ca-trust/source/anchors/ update-ca-trust extract htpasswd -bBc /opt/registry/auth/htpasswd USDREGISTRY_USER USDREGISTRY_PASSWORD podman create --name registry --net host --security-opt label=disable --replace -v /opt/registry/data:/var/lib/registry:z -v /opt/registry/auth:/auth:z -v /opt/registry/conf/config.yml:/etc/docker/registry/config.yml -e "REGISTRY_AUTH=htpasswd" -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry" -e "REGISTRY_HTTP_SECRET=ALongRandomSecretForRegistry" -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd -v /opt/registry/certs:/certs:z -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key docker.io/library/registry:latest [ "USD?" == "0" ] || !! systemctl enable --now registry 1 Replace the location of the PULL_SECRET with the appropriate location for your setup. Name the script file registry.sh and save it. When you run the script, it pulls in the following information: The registry name, based on the hypervisor hostname The necessary credentials and user access details Adjust permissions by adding the execution flag as follows: To run the script without any parameters, enter the following command: The script starts the server. The script uses a systemd service for management purposes. If you need to manage the script, you can use the following commands: The root folder for the registry is in the /opt/registry directory and contains the following subdirectories: certs contains the TLS certificates. auth contains the credentials. data contains the registry images. conf contains the registry configuration. 1.8.12.7.4. Setting up the management cluster for a dual stack network To set up an OpenShift Container Platform management cluster, you can use dev-scripts, or if you are based on virtual machines, you can use the kcli tool. The following instructions are specific to the kcli tool. Ensure that the right networks are prepared for use in the hypervisor. The networks will host both the management and hosted clusters. Enter the following kcli command: where: -c specifies the CIDR for the network. -P dhcp=false configures the network to disable the DHCP, which is handled by the dnsmasq that you configured. -P dns=false configures the network to disable the DNS, which is also handled by the dnsmasq that you configured. --domain sets the domain to search. dns.base.domain.name is the DNS base domain name. dual is the name of the network that you are creating. After the network is created, review the following output: Ensure that the pull secret and kcli plan files are in place so that you can deploy the OpenShift Container Platform management cluster: Confirm that the pull secret is in the same folder as the kcli plan, and that the pull secret file is named openshift_pull.json . Add the kcli plan, which contains the OpenShift Container Platform definition, in the mgmt-compact-hub-dual.yaml file. Ensure that you update the file contents to match your environment: plan: hub-dual force: true version: stable tag: "4.x.y-x86_64" 1 cluster: "hub-dual" dualstack: true domain: dns.base.domain.name api_ip: 192.168.126.10 ingress_ip: 192.168.126.11 service_networks: - 172.30.0.0/16 - fd02::/112 cluster_networks: - 10.132.0.0/14 - fd01::/48 disconnected_url: registry.dns.base.domain.name:5000 disconnected_update: true disconnected_user: dummy disconnected_password: dummy disconnected_operators_version: v4.14 disconnected_operators: - name: metallb-operator - name: lvms-operator channels: - name: stable-4.14 disconnected_extra_images: - quay.io/user-name/trbsht:latest - quay.io/user-name/hypershift:BMSelfManage-v4.14-rc-v3 - registry.redhat.io/openshift4/ose-kube-rbac-proxy:v4.10 dualstack: true disk_size: 200 extra_disks: [200] memory: 48000 numcpus: 16 ctlplanes: 3 workers: 0 manifests: extra-manifests metal3: true network: dual users_dev: developer users_devpassword: developer users_admin: admin users_adminpassword: admin metallb_pool: dual-virtual-network metallb_ranges: - 192.168.126.150-192.168.126.190 metallb_autoassign: true apps: - users - lvms-operator - metallb-operator vmrules: - hub-bootstrap: nets: - name: ipv6 mac: aa:aa:aa:aa:10:07 - hub-ctlplane-0: nets: - name: ipv6 mac: aa:aa:aa:aa:10:01 - hub-ctlplane-1: nets: - name: ipv6 mac: aa:aa:aa:aa:10:02 - hub-ctlplane-2: nets: - name: ipv6 mac: aa:aa:aa:aa:10:03 1 Replace 4.x.y with the supported OpenShift Container Platform version you want to use. To provision the management cluster, enter the following command: , configure the web server. 1.8.12.7.4.1. Additional resources For more information about the parameters in the kcli plan file, see Create a parameters.yml in the official kcli documentation. 1.8.12.7.5. Configuring the web server for a dual stack network You need to configure an additional web server to host the Red Hat Enterprise Linux CoreOS (RHCOS) images that are associated with the OpenShift Container Platform release that you are deploying as a hosted cluster. To configure the web server, complete the following steps: Extract the openshift-install binary from the OpenShift Container Platform release that you want to use by entering the following command: oc adm -a USD{LOCAL_SECRET_JSON} release extract --command=openshift-install "USD{LOCAL_REGISTRY}/USD{LOCAL_REPOSITORY}:USD{OCP_RELEASE}-USD{ARCHITECTURE}" Run the following script. The script creates a folder in the /opt/srv directory. The folder contains the RHCOS images to provision the worker nodes. #!/bin/bash WEBSRV_FOLDER=/opt/srv ROOTFS_IMG_URL="USD(./openshift-install coreos print-stream-json | jq -r '.architectures.x86_64.artifacts.metal.formats.pxe.rootfs.location')" 1 LIVE_ISO_URL="USD(./openshift-install coreos print-stream-json | jq -r '.architectures.x86_64.artifacts.metal.formats.iso.disk.location')" 2 mkdir -p USD{WEBSRV_FOLDER}/images curl -Lk USD{ROOTFS_IMG_URL} -o USD{WEBSRV_FOLDER}/images/USD{ROOTFS_IMG_URL##*/} curl -Lk USD{LIVE_ISO_URL} -o USD{WEBSRV_FOLDER}/images/USD{LIVE_ISO_URL##*/} chmod -R 755 USD{WEBSRV_FOLDER}/* ## Run Webserver podman ps --noheading | grep -q websrv-ai if [[ USD? == 0 ]];then echo "Launching Registry pod..." /usr/bin/podman run --name websrv-ai --net host -v /opt/srv:/usr/local/apache2/htdocs:z quay.io/alosadag/httpd:p8080 fi 1 You can find the ROOTFS_IMG_URL value on the OpenShift CI Release page. 2 You can find the LIVE_ISO_URL value on the OpenShift CI Release page. After the download is completed, a container runs to host the images on a web server. The container uses a variation of the official HTTPd image, which also enables it to work with IPv6 networks. 1.8.12.7.6. Configuring image mirroring for a dual stack network Image mirroring is the process of fetching images from external registries, such as registry.redhat.com or quay.io , and storing them in your private registry. 1.8.12.7.6.1. Completing the mirroring process Note: Start the mirroring process after the registry server is running. In the following procedures, the oc-mirror tool is used, which is a binary that uses the ImageSetConfiguration object. In the file, you can specify the following information: The OpenShift Container Platform versions to mirror. The versions are in quay.io . The additional Operators to mirror. Select packages individually. The extra images that you want to add to the repository. To configure image mirroring, complete the following steps: Ensure that your USD{HOME}/.docker/config.json file is updated with the registries that you are going to mirror from and with the private registry that you plan to push the images to. By using the following example, create an ImageSetConfiguration object to use for mirroring. Replace values as needed to match your environment: 1 Replace 4.x.y with the supported OpenShift Container Platform version you want to use. Start the mirroring process by entering the following command: After the mirroring process is finished, you have a new folder named oc-mirror-workspace/results-XXXXXX/ , which contains the ICSP and the catalog sources to apply on the hosted cluster. Mirror the nightly or CI versions of OpenShift Container Platform by using the oc adm release mirror command. Enter the following command: Replace 4.x.y with the supported OpenShift Container Platform version you want to use. Mirror the latest multicluster engine operator images by following the steps in Install on disconnected networks . 1.8.12.7.6.2. Applying objects in the management cluster After the mirroring process is complete, you need to apply two objects in the management cluster: Image Content Source Policies (ICSP) or Image Digest Mirror Set (IDMS) Catalog sources When you use the oc-mirror tool, the output artifacts are in a folder named oc-mirror-workspace/results-XXXXXX/ . ICSP or IDMS initiates a MachineConfig change that does not restart your nodes but restarts the kubelet on each of them. After the nodes are marked as READY , you need to apply the newly generated catalog sources. The catalog sources initiate actions in the openshift-marketplace Operator, such as downloading the catalog image and processing it to retrieve all the PackageManifests that are included in that image. To check the new sources, run the following command by using the new CatalogSource as a source: To apply the artifacts, complete the following steps: Create the ICSP or IDMS artifacts by entering the following command: Wait for the nodes to become ready, and then enter the following command: , deploy multicluster engine operator. 1.8.12.7.6.3. Additional resources If you are working in a virtual environment, after you configure mirroring, ensure that you meet the prerequisites for hosted control planes on OpenShift Virtualization . For more information about mirroring nightly or CI versions of OpenShift Container Platform, see Mirroring images for a disconnected installation using the oc-mirror plugin . 1.8.12.7.7. Deploying multicluster engine operator for a dual stack network The multicluster engine operator plays a crucial role in deploying clusters across providers. If you already installed Red Hat Advanced Cluster Management, you do not need to install multicluster engine operator because it is automatically installed. If you do not have multicluster engine operator installed, review the following documentation to understand the prerequisites and steps to install it: About cluster lifecycle with multicluster engine operator Installing and upgrading multicluster engine operator 1.8.12.7.7.1. Deploying AgentServiceConfig resources The AgentServiceConfig custom resource is an essential component of the Assisted Service add-on that is part of multicluster engine operator. It is responsible for bare metal cluster deployment. When the add-on is enabled, you deploy the AgentServiceConfig resource to configure the add-on. In addition to configuring the AgentServiceConfig resource, you need to include additional config maps to ensure that multicluster engine operator functions properly in a disconnected environment. Configure the custom registries by adding the following config map, which contains the disconnected details to customize the deployment: --- apiVersion: v1 kind: ConfigMap metadata: name: custom-registries namespace: multicluster-engine labels: app: assisted-service data: ca-bundle.crt: | -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- registries.conf: | unqualified-search-registries = ["registry.access.redhat.com", "docker.io"] [[registry]] prefix = "" location = "registry.redhat.io/openshift4" mirror-by-digest-only = true [[registry.mirror]] location = "registry.dns.base.domain.name:5000/openshift4" 1 [[registry]] prefix = "" location = "registry.redhat.io/rhacm2" mirror-by-digest-only = true ... ... 1 Replace dns.base.domain.name with the DNS base domain name. The object contains two fields: Custom CAs: This field contains the Certificate Authorities (CAs) that are loaded into the various processes of the deployment. Registries: The Registries.conf field contains information about images and namespaces that need to be consumed from a mirror registry rather than the original source registry. Configure the Assisted Service by adding the AssistedServiceConfig object, as shown in the following example: --- apiVersion: agent-install.openshift.io/v1beta1 kind: AgentServiceConfig metadata: annotations: unsupported.agent-install.openshift.io/assisted-service-configmap: assisted-service-config 1 name: agent namespace: multicluster-engine spec: mirrorRegistryRef: name: custom-registries 2 databaseStorage: storageClassName: lvms-vg1 accessModes: - ReadWriteOnce resources: requests: storage: 10Gi filesystemStorage: storageClassName: lvms-vg1 accessModes: - ReadWriteOnce resources: requests: storage: 20Gi osImages: 3 - cpuArchitecture: x86_64 openshiftVersion: "4.14" rootFSUrl: http://registry.dns.base.domain.name:8080/images/rhcos-414.92.202308281054-0-live-rootfs.x86_64.img 4 url: http://registry.dns.base.domain.name:8080/images/rhcos-414.92.202308281054-0-live.x86_64.iso version: 414.92.202308281054-0 1 The metadata.annotations["unsupported.agent-install.openshift.io/assisted-service-configmap"] annotation references the config map name that the Operator consumes to customize behavior. 2 The spec.mirrorRegistryRef.name annotation points to the config map that contains disconnected registry information that the Assisted Service Operator consumes. This config map adds those resources during the deployment process. 3 The spec.osImages field contains different versions available for deployment by this Operator. This field is mandatory. This example assumes that you already downloaded the RootFS and LiveISO files. 4 In the rootFSUrl and url fields, replace dns.base.domain.name with the DNS base domain name. Deploy all of the objects by concatenating them into a single file and applying them to the management cluster. To do so, enter the following command: The command triggers two pods, as shown in this example output: 1 The assisted-image-service pod is responsible for creating the Red Hat Enterprise Linux CoreOS (RHCOS) boot image template, which is customized for each cluster that you deploy. 2 The assisted-service refers to the Operator. 1.8.12.7.8. Configuring TLS certificates for a dual stack network Several TLS certificates are involved in the process to configure hosted control planes in a disconnected environment. To add a Certificate Authority (CA) to the management cluster, you need to modify the content of the following files in the OpenShift Container Platform control plane and worker nodes: /etc/pki/ca-trust/extracted/pem/ /etc/pki/ca-trust/source/anchors /etc/pki/tls/certs/ To add a CA to the management cluster, complete the following steps: Complete the steps in Updating the CA bundle in the official OpenShift Container Platform documentation. That method involves using the image-registry-operator , which deploys the CAs to the OpenShift Container Platform nodes. If that method does not apply to your situation, check whether the openshift-config namespace in the management cluster contains a config map named user-ca-bundle . If the namespace contains that config map, enter the following command: If the namespace does not contain that config map, enter the following command: 1.8.12.7.9. Deploying the hosted cluster for a dual stack network A hosted cluster is an OpenShift Container Platform cluster with its control plane and API endpoint hosted on a management cluster. The hosted cluster includes the control plane and its corresponding data plane. Although you can use the console in Red Hat Advanced Cluster Management to create a hosted cluster, the following procedures use manifests, which provide more flexibility for modifying the related artifacts. 1.8.12.7.9.1. Deploying hosted cluster objects For the purposes of this procedure, the following values are used: HostedCluster name: hosted-dual HostedCluster namespace: clusters Disconnected: true Network stack: Dual Typically, the HyperShift Operator creates the HostedControlPlane namespace. However, in this case, you want to include all the objects before the HyperShift Operator begins to reconcile the HostedCluster object. Then, when the Operator starts the reconciliation process, it can find all of the objects in place. Create a YAML file with the following information about the namespaces: --- apiVersion: v1 kind: Namespace metadata: creationTimestamp: null name: clusters-hosted-dual spec: {} status: {} --- apiVersion: v1 kind: Namespace metadata: creationTimestamp: null name: clusters spec: {} status: {} Create a YAML file with the following information about the config maps and secrets to include in the HostedCluster deployment: --- apiVersion: v1 data: ca-bundle.crt: | -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- kind: ConfigMap metadata: name: user-ca-bundle namespace: clusters --- apiVersion: v1 data: .dockerconfigjson: xxxxxxxxx kind: Secret metadata: creationTimestamp: null name: hosted-dual-pull-secret namespace: clusters --- apiVersion: v1 kind: Secret metadata: name: sshkey-cluster-hosted-dual namespace: clusters stringData: id_rsa.pub: ssh-rsa xxxxxxxxx --- apiVersion: v1 data: key: nTPtVBEt03owkrKhIdmSW8jrWRxU57KO/fnZa8oaG0Y= kind: Secret metadata: creationTimestamp: null name: hosted-dual-etcd-encryption-key namespace: clusters type: Opaque Create a YAML file that contains the RBAC roles so that Assisted Service agents can be in the same HostedControlPlane namespace as the hosted control plane and still be managed by the cluster API: apiVersion: rbac.authorization.k8s.io/v1 kind: Role metadata: creationTimestamp: null name: capi-provider-role namespace: clusters-hosted-dual rules: - apiGroups: - agent-install.openshift.io resources: - agents verbs: - '*' Create a YAML file with information about the HostedCluster object, replacing values as necessary: apiVersion: hypershift.openshift.io/v1beta1 kind: HostedCluster metadata: name: hosted-dual namespace: clusters spec: additionalTrustBundle: name: "user-ca-bundle" olmCatalogPlacement: guest imageContentSources: 1 - source: quay.io/openshift-release-dev/ocp-v4.0-art-dev mirrors: - registry.dns.base.domain.name:5000/openshift/release 2 - source: quay.io/openshift-release-dev/ocp-release mirrors: - registry.dns.base.domain.name:5000/openshift/release-images - mirrors: ... ... autoscaling: {} controllerAvailabilityPolicy: SingleReplica dns: baseDomain: dns.base.domain.name etcd: managed: storage: persistentVolume: size: 8Gi restoreSnapshotURL: null type: PersistentVolume managementType: Managed fips: false networking: clusterNetwork: - cidr: 10.132.0.0/14 - cidr: fd01::/48 networkType: OVNKubernetes serviceNetwork: - cidr: 172.31.0.0/16 - cidr: fd02::/112 platform: agent: agentNamespace: clusters-hosted-dual type: Agent pullSecret: name: hosted-dual-pull-secret release: image: registry.dns.base.domain.name:5000/openshift/release-images:4.x.y-x86_64 3 secretEncryption: aescbc: activeKey: name: hosted-dual-etcd-encryption-key type: aescbc services: - service: APIServer servicePublishingStrategy: nodePort: address: api.hosted-dual.dns.base.domain.name type: NodePort - service: OAuthServer servicePublishingStrategy: nodePort: address: api.hosted-dual.dns.base.domain.name type: NodePort - service: OIDC servicePublishingStrategy: nodePort: address: api.hosted-dual.dns.base.domain.name type: NodePort - service: Konnectivity servicePublishingStrategy: nodePort: address: api.hosted-dual.dns.base.domain.name type: NodePort - service: Ignition servicePublishingStrategy: nodePort: address: api.hosted-dual.dns.base.domain.name type: NodePort sshKey: name: sshkey-cluster-hosted-dual status: controlPlaneEndpoint: host: "" port: 0 1 The imageContentSources section contains mirror references for user workloads within the hosted cluster. 2 Throughout the YAML file, replace dns.base.domain.name with the DNS base domain name. 3 Replace 4.x.y with the supported OpenShift Container Platform version you want to use. Add an annotation in the HostedCluster object that points to the HyperShift Operator release in the OpenShift Container Platform release: Obtain the image payload by entering the following command: where dns.base.domain.name is the DNS base domain name and 4.x.y is the supported OpenShift Container Platform version you want to use. See the following output: By using the OpenShift Container Platform Images namespace, check the digest by entering the following command: where dns.base.domain.name is the DNS base domain name. See the following output: Note: The release image that is set in the HostedCluster object must use the digest rather than the tag; for example, quay.io/openshift-release-dev/ocp-release@sha256:e3ba11bd1e5e8ea5a0b36a75791c90f29afb0fdbe4125be4e48f69c76a5c47a0 . Create all of the objects that you defined in the YAML files by concatenating them into a file and applying them against the management cluster. To do so, enter the following command: See the output for the hosted control plane: See the output for the hosted cluster: , create a NodePool object. 1.8.12.7.9.2. Creating a NodePool object for the hosted cluster A NodePool is a scalable set of worker nodes that is associated with a hosted cluster. NodePool machine architectures remain consistent within a specific pool and are independent of the machine architecture of the control plane. Create a YAML file with the following information about the NodePool object, replacing values as necessary: apiVersion: hypershift.openshift.io/v1beta1 kind: NodePool metadata: creationTimestamp: null name: hosted-dual namespace: clusters spec: arch: amd64 clusterName: hosted-dual management: autoRepair: false 1 upgradeType: InPlace 2 nodeDrainTimeout: 0s platform: type: Agent release: image: registry.dns.base.domain.name:5000/openshift/release-images:4.x.y-x86_64 3 replicas: 0 status: replicas: 0 4 1 The autoRepair field is set to false because the node will not be re-created if it is removed. 2 The upgradeType is set to InPlace , which indicates that the same bare metal node is reused during an upgrade. 3 All of the nodes included in this NodePool are based on the following OpenShift Container Platform version: 4.x.y-x86_64 . Replace the dns.base.domain.name value with your DNS base domain name and the 4.x.y value with the supported OpenShift Container Platform version you want to use. 4 The replicas value is set to 0 so that you can scale them when needed. It is important to keep the NodePool replicas at 0 until all steps are completed. Create the NodePool object by entering the following command: See the output: , create an InfraEnv resource. 1.8.12.7.9.3. Creating an InfraEnv resource for the hosted cluster The InfraEnv resource is an Assisted Service object that includes essential details, such as the pullSecretRef and the sshAuthorizedKey . Those details are used to create the Red Hat Enterprise Linux CoreOS (RHCOS) boot image that is customized for the hosted cluster. Create a YAML file with the following information about the InfraEnv resource, replacing values as necessary: --- apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv metadata: name: hosted-dual namespace: clusters-hosted-dual spec: pullSecretRef: 1 name: pull-secret sshAuthorizedKey: ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQDk7ICaUE+/k4zTpxLk4+xFdHi4ZuDi5qjeF52afsNkw0w/glILHhwpL5gnp5WkRuL8GwJuZ1VqLC9EKrdmegn4MrmUlq7WTsP0VFOZFBfq2XRUxo1wrRdor2z0Bbh93ytR+ZsDbbLlGngXaMa0Vbt+z74FqlcajbHTZ6zBmTpBVq5RHtDPgKITdpE1fongp7+ZXQNBlkaavaqv8bnyrP4BWahLP4iO9/xJF9lQYboYwEEDzmnKLMW1VtCE6nJzEgWCufACTbxpNS7GvKtoHT/OVzw8ArEXhZXQUS1UY8zKsX2iXwmyhw5Sj6YboA8WICs4z+TrFP89LmxXY0j6536TQFyRz1iB4WWvCbH5n6W+ABV2e8ssJB1AmEy8QYNwpJQJNpSxzoKBjI73XxvPYYC/IjPFMySwZqrSZCkJYqQ023ySkaQxWZT7in4KeMu7eS2tC+Kn4deJ7KwwUycx8n6RHMeD8Qg9flTHCv3gmab8JKZJqN3hW1D378JuvmIX4V0= 2 1 The pullSecretRef refers to the config map reference in the same namespace as the InfraEnv , where the pull secret is used. 2 The sshAuthorizedKey represents the SSH public key that is placed in the boot image. The SSH key allows access to the worker nodes as the core user. Create the InfraEnv resource by entering the following command: See the following output: , create worker nodes. 1.8.12.7.9.4. Creating worker nodes for the hosted cluster If you are working on a bare metal platform, creating worker nodes is crucial to ensure that the details in the BareMetalHost are correctly configured. If you are working with virtual machines, you can complete the following steps to create empty worker nodes for the Metal3 Operator to consume. To do so, you use the kcli tool. If this is not your first attempt to create worker nodes, you must first delete your setup. To do so, delete the plan by entering the following command: When you are prompted to confirm whether you want to delete the plan, type y . Confirm that you see a message stating that the plan was deleted. Create the virtual machines by entering the following commands: where: start=False means that the virtual machine (VM) will not automatically start upon creation. uefi_legacy=true means that you will use UEFI legacy boot to ensure compatibility with UEFI implementations. plan=hosted-dual indicates the plan name, which identifies a group of machines as a cluster. memory=8192 and numcpus=16 are parameters that specify the resources for the VM, including the RAM and CPU. disks=[200,200] indicates that you are creating two thin-provisioned disks in the VM. nets=[{"name": "dual", "mac": "aa:aa:aa:aa:02:13"}] are network details, including the network name to connect to and the MAC address of the primary interface. restart ksushy restarts the ksushy tool to ensure that the tool detects the VMs that you added. See the resulting output: , create bare metal hosts for the hosted cluster. 1.8.12.7.9.5. Creating bare metal hosts for the hosted cluster A bare metal host is an openshift-machine-api object that encompasses physical and logical details so that it can be identified by a Metal3 Operator. Those details are associated with other Assisted Service objects, known as agents . Important: Before you create the bare metal host and destination nodes, you must create the virtual machines. To create a bare metal host, complete the following steps: Create a YAML file with the following information: Note: Because you have at least one secret that holds the bare metal host credentials, you need to create at least two objects for each worker node. --- apiVersion: v1 kind: Secret metadata: name: hosted-dual-worker0-bmc-secret namespace: clusters-hosted-dual data: password: YWRtaW4= username: YWRtaW4= type: Opaque --- apiVersion: metal3.io/v1alpha1 kind: BareMetalHost metadata: name: hosted-dual-worker0 namespace: clusters-hosted-dual labels: infraenvs.agent-install.openshift.io: hosted-dual 1 annotations: inspect.metal3.io: disabled bmac.agent-install.openshift.io/hostname: hosted-dual-worker0 2 spec: automatedCleaningMode: disabled 3 bmc: disableCertificateVerification: true 4 address: redfish-virtualmedia://[192.168.126.1]:9000/redfish/v1/Systems/local/hosted-dual-worker0 5 credentialsName: hosted-dual-worker0-bmc-secret 6 bootMACAddress: aa:aa:aa:aa:02:11 7 online: true 8 1 infraenvs.agent-install.openshift.io serves as the link between the Assisted Installer and the BareMetalHost objects. 2 bmac.agent-install.openshift.io/hostname represents the node name that is adopted during deployment. 3 automatedCleaningMode prevents the node from being erased by the Metal3 Operator. 4 disableCertificateVerification is set to true to bypass certificate validation from the client. 5 address denotes the baseboard management controller (BMC) address of the worker node. 6 credentialsName points to the secret where the user and password credentials are stored. 7 bootMACAddress indicates the interface MAC address that the node starts from. 8 online defines the state of the node after the BareMetalHost object is created. Deploy the BareMetalHost object by entering the following command: During the process, you can view the following output: This output indicates that the process is trying to reach the nodes: This output indicates that the nodes are starting: This output indicates that the nodes started successfully: After the nodes start, notice the agents in the namespace, as shown in this example: The agents represent nodes that are available for installation. To assign the nodes to a hosted cluster, scale up the node pool. 1.8.12.7.9.6. Scaling up the node pool After you create the bare metal hosts, their statuses change from Registering to Provisioning to Provisioned . The nodes start with the LiveISO of the agent and a default pod that is named agent . That agent is responsible for receiving instructions from the Assisted Service Operator to install the OpenShift Container Platform payload. To scale up the node pool, enter the following command: After the scaling process is complete, notice that the agents are assigned to a hosted cluster: Also notice that the node pool replicas are set: Replace 4.x.y with the supported OpenShift Container Platform version that you want to use. Wait until the nodes join the cluster. During the process, the agents provide updates on their stage and status. , monitor the deployment of the hosted cluster. 1.8.12.7.10. Finishing the hosted cluster deployment for a dual stack network You can monitor the deployment of a hosted cluster from two perspectives: the control plane and the data plane. 1.8.12.7.10.1. Monitoring the control plane While the hosted cluster is deploying, you can enter the following commands to monitor the control plane: Those commands provide information about the following artifacts: The HyperShift Operator The HostedControlPlane pod The bare metal hosts The agents The InfraEnv resource The HostedCluster and NodePool resources 1.8.12.7.10.2. Monitoring the data plane To monitor how the Operators are progressing during the deployment process, enter the following commands: Those commands provide information about the following artifacts: The cluster version The nodes, specifically, about whether the nodes joined the cluster The cluster Operators 1.8.13. Manually importing a hosted control plane cluster Hosted clusters are automatically imported into multicluster engine operator after the hosted control plane becomes available. If you want to import hosted clusters manually, complete the following steps: In the console, click Infrastructure > Clusters and select the hosted cluster that you want to import. Click Import hosted cluster . Note: For your discovered hosted cluster, you can also import from the console, but the cluster must be in an upgradable state. Import on your cluster is disabled if the hosted cluster is not in an upgradable state because the hosted control plane is not available. Click Import to begin the process. The status is Importing while the cluster receives updates and then changes to Ready . 1.8.13.1. Manually importing a hosted control plane cluster on AWS You can also import a hosted control plane cluster on AWS with the command line interface by completing the following steps: Create your ManagedCluster resource by using the following sample YAML file: apiVersion: cluster.open-cluster-management.io/v1 kind: ManagedCluster metadata: annotations: import.open-cluster-management.io/hosting-cluster-name: local-cluster import.open-cluster-management.io/klusterlet-deploy-mode: Hosted open-cluster-management/created-via: hypershift labels: cloud: auto-detect cluster.open-cluster-management.io/clusterset: default name: <cluster_name> vendor: OpenShift name: <cluster_name> spec: hubAcceptsClient: true leaseDurationSeconds: 60 Replace <cluster_name> with the name of your hosted cluster. Run the following command to apply the resource: Replace <file_name> with the YAML file name you created in the step. Create your KlusterletAddonConfig resource by using the following sample YAML file. This only applies to Red Hat Advanced Cluster Management. If you have installed multicluster engine operator only, skip this step: apiVersion: agent.open-cluster-management.io/v1 kind: KlusterletAddonConfig metadata: name: <cluster_name> namespace: <cluster_name> spec: clusterName: <cluster_name> clusterNamespace: <cluster_name> clusterLabels: cloud: auto-detect vendor: auto-detect applicationManager: enabled: true certPolicyController: enabled: true policyController: enabled: true searchCollector: enabled: false Replace <cluster_name> with the name of your hosted cluster. Run the following command to apply the resource: Replace <file_name> with the YAML file name you created in the step. After the import process is complete, your hosted cluster becomes visible in the console. You can also check the status of your hosted cluster by running the following command: 1.8.13.2. Additional resources For instructions to disable the automatic import of hosted clusters, see Disabling the automatic import of hosted clusters into multicluster engine operator . 1.8.13.3. Disabling the automatic import of hosted clusters into multicluster engine operator Hosted clusters are automatically imported into multicluster engine operator after the control plane becomes available, you can disable the automatic import of hosted clusters. Any hosted clusters that were previously imported are not affected, even if you disable automatic import. When you upgrade to multicluster engine operator 2.5 and automatic import is enabled, all hosted clusters that are not imported are automatically imported if their control planes are available. Note: All Red Hat Advanced Cluster Management add-ons are also enabled if Red Hat Advanced Cluster Management is installed. When automatic import is disabled, only newly created hosted clusters are not automatically imported. Hosted clusters that were already imported are not affected. You can still manually import clusters by using the console or by creating the ManagedCluster and KlusterletAddonConfig custom resources. To disable the automatic import of hosted clusters, complete the following steps: On the hub cluster, open the hypershift-addon-deploy-config specification that is in the AddonDeploymentConfig resource in the namespace where multicluster engine operator is installed by entering the following command: In the spec.customizedVariables section, add the autoImportDisabled variable with value of "true" , as shown in the following example: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: AddOnDeploymentConfig metadata: name: hypershift-addon-deploy-config namespace: multicluster-engine spec: customizedVariables: - name: hcMaxNumber value: "80" - name: hcThresholdNumber value: "60" - name: autoImportDisabled value: "true" To re-enable automatic import, set the value of the autoImportDisabled variable to "false" or remove the variable from the AddonDeploymentConfig resource. 1.8.13.3.1. Additional resources For instructions to manually import a hosted cluster, see Manually importing a hosted control plane cluster . 1.8.14. Enabling or disabling the hosted control plane feature The hosted control planes feature, as well as the hypershift-addon managed cluster add-on, are enabled by default. If you want to disable the feature, or if you disabled it and want to manually enable it, see the following procedures: Manually enabling the hosted control planes feature Disabling the hosted control planes feature 1.8.14.1. Manually enabling the hosted control planes feature You can run the following command to enable the feature: 1 The default MultiClusterEngine resource instance name is multiclusterengine , but you can get the MultiClusterEngine name from your cluster by running the following command: USD oc get mce . Run the following command to verify that the hypershift and hypershift-local-hosting features are enabled in the MultiClusterEngine custom resource: 1 The default MultiClusterEngine resource instance name is multiclusterengine , but you can get the MultiClusterEngine name from your cluster by running the following command: USD oc get mce . The output resembles the following example: apiVersion: multicluster.openshift.io/v1 kind: MultiClusterEngine metadata: name: multiclusterengine spec: overrides: components: - name: hypershift enabled: true - name: hypershift-local-hosting enabled: true 1.8.14.1.1. Manually enabling the hypershift-addon managed cluster add-on for local-cluster Enabling the hosted control planes feature automatically enables the hypershift-addon managed cluster add-on. If you need to enable the hypershift-addon managed cluster add-on manually, complete the following steps to use the hypershift-addon to install the HyperShift Operator on local-cluster : Create the ManagedClusterAddon HyperShift add-on by creating a file that resembles the following example: apiVersion: addon.open-cluster-management.io/v1alpha1 kind: ManagedClusterAddOn metadata: name: hypershift-addon namespace: local-cluster spec: installNamespace: open-cluster-management-agent-addon Apply the file by running the following command: Replace filename with the name of the file that you created. Confirm that the hypershift-addon is installed by running the following command: If the add-on is installed, the output resembles the following example: Your HyperShift add-on is installed and the hosting cluster is available to create and manage hosted clusters. 1.8.14.2. Disabling the hosted control planes feature You can uninstall the HyperShift Operator and disable the hosted control plane. When you disable the hosted control plane cluster feature, you must destroy the hosted cluster and the managed cluster resource on multicluster engine operator, as described in the Managing hosted control plane clusters topics. 1.8.14.2.1. Uninstalling the HyperShift Operator To uninstall the HyperShift Operator and disable the hypershift-addon from the local-cluster , complete the following steps: Run the following command to ensure that there is no hosted cluster running: Important: If a hosted cluster is running, the HyperShift Operator does not uninstall, even if the hypershift-addon is disabled. Disable the hypershift-addon by running the following command: 1 The default MultiClusterEngine resource instance name is multiclusterengine , but you can get the MultiClusterEngine name from your cluster by running the following command: USD oc get mce . Note: You can also disable the hypershift-addon for the local-cluster from the multicluster engine operator console after disabling the hypershift-addon . 1.8.14.2.2. Disabling the hosted control planes feature You must first uninstall the HyperShift Operator before disabling the hosted control planes feature. Run the following command to disable the hosted control planes feature: 1 The default MultiClusterEngine resource instance name is multiclusterengine , but you can get the MultiClusterEngine name from your cluster by running the following command: USD oc get mce . You can verify that the hypershift and hypershift-local-hosting features are disabled in the MultiClusterEngine custom resource by running the following command: 1 The default MultiClusterEngine resource instance name is multiclusterengine , but you can get the MultiClusterEngine name from your cluster by running the following command: USD oc get mce . See the following example where hypershift and hypershift-local-hosting have their enabled: flags set to false : apiVersion: multicluster.openshift.io/v1 kind: MultiClusterEngine metadata: name: multiclusterengine spec: overrides: components: - name: hypershift enabled: false - name: hypershift-local-hosting enabled: false 1.8.14.3.

Troubleshooting Before using the Troubleshooting guide, you can run the oc adm must-gather command to gather details, logs, and take steps in debugging issues. For more details, see Running the must-gather command to troubleshoot . Additionally, check your role-based access. See multicluster engine operator Role-based access control for details. 1.10.1. Documented troubleshooting View the list of troubleshooting topics for the multicluster engine operator: Installation: To view the main documentation for the installing tasks, see Installing and upgrading multicluster engine operator . Troubleshooting installation status stuck in installing or pending Troubleshooting reinstallation failure Cluster management: To view the main documentation about managing your clusters, see Cluster lifecycle introduction . Troubleshooting adding day-two nodes to an existing cluster fails with pending user action Troubleshooting an offline cluster Troubleshooting a managed cluster import failure Reimporting cluster fails with unknown authority error Troubleshooting cluster with pending import status Troubleshooting imported clusters offline after certificate change Troubleshooting cluster status changing from offline to available Troubleshooting cluster creation on VMware vSphere Troubleshooting cluster in console with pending or failed status Troubleshooting OpenShift Container Platform version 3.11 cluster import failure Troubleshooting Klusterlet with degraded conditions Namespace remains after deleting a cluster Auto-import-secret-exists error when importing a cluster Troubleshooting missing PlacementDecision after creating Placement Troubleshooting a discovery failure of bare metal hosts on Dell hardware Troubleshooting Minimal ISO boot failures Troubleshooting installation status stuck at Installing on a ROSA with hosted control planes cluster Troubleshooting all managed clusters become Unknown on a ROSA with hosted control planes cluster Troubleshooting an attempt to upgrade managed cluster with missing OpenShift Container Platform version 1.10.2. Running the must-gather command to troubleshoot To get started with troubleshooting, learn about the troubleshooting scenarios for users to run the must-gather command to debug the issues, then see the procedures to start using the command. Required access: Cluster administrator 1.10.2.1. Must-gather scenarios Scenario one: Use the Documented troubleshooting section to see if a solution to your problem is documented. The guide is organized by the major functions of the product. With this scenario, you check the guide to see if your solution is in the documentation. Scenario two: If your problem is not documented with steps to resolve, run the must-gather command and use the output to debug the issue. Scenario three: If you cannot debug the issue using your output from the must-gather command, then share your output with Red Hat Support. 1.10.2.2. Must-gather procedure See the following procedure to start using the must-gather command: Learn about the must-gather command and install the prerequisites that you need at Gathering data about your cluster in the OpenShift Container Platform documentation. Log in to your cluster. For the usual use-case, you should run the must-gather while you are logged into your engine cluster. Note: If you want to check your managed clusters, find the gather-managed.log file that is located in the cluster-scoped-resources directory: Check for managed clusters that are not set True for the JOINED and AVAILABLE column. You can run the must-gather command on those clusters that are not connected with True status. Add the multicluster engine for Kubernetes image that is used for gathering data and the directory. Run the following command: Go to your specified directory to see your output, which is organized in the following levels: Two peer levels: cluster-scoped-resources and namespace resources. Sub-level for each: API group for the custom resource definitions for both cluster-scope and namespace-scoped resources. level for each: YAML file sorted by kind . 1.10.2.3. Must-gather in a disconnected environment Complete the following steps to run the must-gather command in a disconnected environment: In a disconnected environment, mirror the Red Hat operator catalog images into their mirror registry. For more information, see Install on disconnected networks . Run the following command to extract logs, which reference the image from their mirror registry.

Must-gather for a hosted cluster If you experience issues with hosted control plane clusters, you can run the must-gather command to gather information for troubleshooting. Required access: Cluster administration 1.10.2.4.1. About the must-gather command for hosted clusters The must-gather command generates output for the management cluster and the hosted cluster. Learn more about the data that is collected. The following data is collected from the multicluster engine operator hub cluster: Cluster-scoped resources: These resources are node definitions of the management cluster. The hypershift-dump compressed file: This file is useful if you need to share the content with other people. Namespaced resources: These resources include all of the objects from the relevant namespaces, such as config maps, services, events, and logs. Network logs: These logs include the OVN northbound and southbound databases and the status for each one. Hosted clusters: This level of output involves all of the resources inside of the hosted cluster. The following data is collected data from the hosted cluster: Cluster-scoped resources: These resources include all of the cluster-wide objects, such as nodes and CRDs. Namespaced resources: These resources include all of the objects from the relevant namespaces, such as config maps, services, events, and logs. Although the output does not contain any secret objects from the cluster, it can contain references to the names of the secrets. 1.10.2.4.2. Prerequisites To gather information by running the must-gather command, you must meet the following prerequisites: You must ensure that the kubeconfig file is loaded and is pointing to the multicluster engine operator hub cluster. You must have the name value for the HostedCluster resource and the namespace where the custom resource is deployed. 1.10.2.4.3. Entering the must-gather command for hosted clusters See the following process to collect information from the must-gather command: Enter the following command to collect information about the hosted cluster. Replace <v2.x> with the version that you are using: The hosted-cluster-namespace=HOSTEDCLUSTERNAMESPACE parameter is optional. If you do not include the parameter, the command runs as though the hosted cluster is in the default namespace, which is clusters . To save the results of the command to a compressed file, run the same command and add the --dest-dir=NAME parameter, which is optional. Replace NAME with the name of the directory where you want to save the results. Replace <v2.x> with the version that you are using. See the following command with the optional parameter: 1.10.2.4.4. Entering the must-gather command in a disconnected environment Complete the following steps to run the must-gather command in a disconnected environment: In a disconnected environment, mirror the Red Hat operator catalog images into their mirror registry.

Troubleshooting: Adding day-two nodes to an existing cluster fails with pending user action Adding a node, or scaling out, to your existing cluster that is created by the multicluster engine for Kubernetes operator with Zero Touch Provisioning or Host inventory create methods fails during installation. The installation process works correctly during the Discovery phase, but fails on the installation phase. The configuration of the network is failing. From the hub cluster in the integrated console, you see a Pending user action. In the description, you can see it failing on the rebooting step. The error message about failing is not very accurate, since the agent that is running in the installing host cannot report information. 1.10.3.1. Symptom: Installation for day two workers fails After the Discover phase, the host reboots to continue the installation, but it cannot configure the network. Check for the following symptoms and messages: From the hub cluster in the integrated console, check for Pending user action on the adding node, with the Rebooting indicator: From the Red Hat OpenShift Container Platform configuration managed cluster, check the MachineConfigs of the existing cluster. Check if any of the MachineConfigs create any file on the following directories: /sysroot/etc/NetworkManager/system-connections/ /sysroot/etc/sysconfig/network-scripts/ From the terminal of the installing host, check the failing host for the following messages. You can use journalctl to see the log messages: If you get the last message in the log, the networking configuration is not propagated because it already found an existing network configuration on the folders previously listed in the Symptom . 1.10.3.2. Resolving the problem: Recreate the node merging network configuration Perform the following task to use a proper network configuration during the installation: Delete the node from your hub cluster. Repeat your process to install the node in the same way. Create the BareMetalHost object of the node with the following annotation: "bmac.agent-install.openshift.io/installer-args": "[\"--append-karg\", \"coreos.force_persist_ip\"]" The node starts the installation. After the Discovery phase, the node merges the network configuration between the changes on the existing cluster and the initial configuration. 1.10.4. Troubleshooting deletion failure of a hosted control plane cluster on the Agent platform When you destroy a hosted control plane cluster on the Agent platform, all the back-end resources are normally deleted. If the machine resources are not deleted properly, a cluster deletion fails. In that case, you must manually remove the remaining machine resources. 1.10.4.1. Symptom: An error occurs when destroying a hosted control plane cluster After you attempt to destroy the hosted control plane cluster on the Agent platform, the hcp destroy command fails with the following error: + 1.10.4.2. Resolving the problem: Remove the remaining machine resources manually Complete the following steps to destroy a hosted control plane cluster successfully on the Agent platform: Run the following command to see the list of remaining machine resources by replacing <hosted_cluster_namespace> with the name of hosted cluster namespace: See the following example output: Run the following command to remove the machine.cluster.x-k8s.io finalizer attached to machine resources: Run the following command to verify you receive the No resources found message on your terminal: Run the following command to destroy a hosted control plane cluster on the Agent platform: Replace <cluster_name> with the name of your cluster. 1.10.5. Troubleshooting installation status stuck in installing or pending When installing the multicluster engine operator, the MultiClusterEngine remains in Installing phase, or multiple pods maintain a Pending status. 1.10.5.1. Symptom: Stuck in Pending status More than ten minutes passed since you installed MultiClusterEngine and one or more components from the status.components field of the MultiClusterEngine resource report ProgressDeadlineExceeded . Resource constraints on the cluster might be the issue. Check the pods in the namespace where MultiClusterEngine was installed. You might see Pending with a status similar to the following: In this case, the worker nodes resources are not sufficient in the cluster to run the product. 1.10.5.2. Resolving the problem: Adjust worker node sizing If you have this problem, then your cluster needs to be updated with either larger or more worker nodes. See Sizing your cluster for guidelines on sizing your cluster. 1.10.6. Troubleshooting reinstallation failure When reinstalling multicluster engine operator, the pods do not start. 1.10.6.1. Symptom: Reinstallation failure If your pods do not start after you install the multicluster engine operator, it is often because items from a installation of multicluster engine operator were not removed correctly when it was uninstalled. In this case, the pods do not start after completing the installation process. 1.10.6.2. Resolving the problem: Reinstallation failure If you have this problem, complete the following steps: Run the uninstallation process to remove the current components by following the steps in Uninstalling . Install the Helm CLI binary version 3.2.0, or later, by following the instructions at Installing Helm . Ensure that your Red Hat OpenShift Container Platform CLI is configured to run oc commands. See Getting started with the OpenShift CLI in the OpenShift Container Platform documentation for more information about how to configure the oc commands. Copy the following script into a file: Replace <namespace> in the script with the name of the namespace where multicluster engine operator was installed. Ensure that you specify the correct namespace, as the namespace is cleaned out and deleted. Run the script to remove the artifacts from the installation. Run the installation. See Installing while connected online . 1.10.7. Troubleshooting an offline cluster There are a few common causes for a cluster showing an offline status. 1.10.7.1. Symptom: Cluster status is offline After you complete the procedure for creating a cluster, you cannot access it from the Red Hat Advanced Cluster Management console, and it shows a status of offline . 1.10.7.2. Resolving the problem: Cluster status is offline Determine if the managed cluster is available. You can check this in the Clusters area of the Red Hat Advanced Cluster Management console. If it is not available, try restarting the managed cluster. If the managed cluster status is still offline, complete the following steps: Run the oc get managedcluster <cluster_name> -o yaml command on the hub cluster. Replace <cluster_name> with the name of your cluster. Find the status.conditions section. Check the messages for type: ManagedClusterConditionAvailable and resolve any problems. 1.10.8. Troubleshooting a managed cluster import failure If your cluster import fails, there are a few steps that you can take to determine why the cluster import failed. 1.10.8.1. Symptom: Imported cluster not available After you complete the procedure for importing a cluster, you cannot access it from the console. 1.10.8.2. Resolving the problem: Imported cluster not available There can be a few reasons why an imported cluster is not available after an attempt to import it. If the cluster import fails, complete the following steps, until you find the reason for the failed import: On the hub cluster, run the following command to ensure that the import controller is running. You should see two pods that are running. If either of the pods is not running, run the following command to view the log to determine the reason: On the hub cluster, run the following command to determine if the managed cluster import secret was generated successfully by the import controller: If the import secret does not exist, run the following command to view the log entries for the import controller and determine why it was not created: On the hub cluster, if your managed cluster is local-cluster , provisioned by Hive, or has an auto-import secret, run the following command to check the import status of the managed cluster. If the condition ManagedClusterImportSucceeded is not true , the result of the command indicates the reason for the failure. Check the Klusterlet status of the managed cluster for a degraded condition. See Troubleshooting Klusterlet with degraded conditions to find the reason that the Klusterlet is degraded. 1.10.9. Reimporting cluster fails with unknown authority error If you experience a problem when reimporting a managed cluster to your multicluster engine operator hub cluster, follow the procedure to troubleshoot the problem. 1.10.9.1. Symptom: Reimporting cluster fails with unknown authority error After you provision an OpenShift Container Platform cluster with multicluster engine operator, reimporting the cluster might fail with a x509: certificate signed by unknown authority error when you change or add API server certificates to your OpenShift Container Platform cluster. 1.10.9.2. Identifying the problem: Reimporting cluster fails with unknown authority error After failing to reimport your managed cluster, run the following command to get the import controller log on your multicluster engine operator hub cluster: If the following error log appears, your managed cluster API server certificates might have changed: ERROR Reconciler error {"controller": "clusterdeployment-controller", "object": {"name":"awscluster1","namespace":"awscluster1"}, "namespace": "awscluster1", "name": "awscluster1", "reconcileID": "a2cccf24-2547-4e26-95fb-f258a6710d80", "error": "Get \"https://api.awscluster1.dev04.red-chesterfield.com:6443/api?timeout=32s\": x509: certificate signed by unknown authority"} To determine if your managed cluster API server certificates have changed, complete the following steps: Run the following command to specify your managed cluster name by replacing your-managed-cluster-name with the name of your managed cluster: Get your managed cluster kubeconfig secret name by running the following command: Export kubeconfig to a new file by running the following commands: Get the namespace from your managed cluster with kubeconfig by running the following command: If you receive an error that resembles the following message, your cluster API server ceritificates have been changed and your kubeconfig file is invalid. Unable to connect to the server: x509: certificate signed by unknown authority 1.10.9.3. Resolving the problem: Reimporting cluster fails with unknown authority error The managed cluster administrator must create a new valid kubeconfig file for your managed cluster. After creating a new kubeconfig , complete the following steps to update the new kubeconfig for your managed cluster: Run the following commands to set your kubeconfig file path and cluster name. Replace <path_to_kubeconfig> with the path to your new kubeconfig file.

Search the returned results for text that indicates there was a networking connectivity problem. Example includes: no such host . 1.10.10.3. Resolving the problem: Cluster with pending import status Retrieve the port number that is having the problem by entering the following command on the hub cluster: Ensure that the hostname from the managed cluster can be resolved, and that outbound connectivity to the host and port is occurring. If the communication cannot be established by the managed cluster, the cluster import is not complete. The cluster status for the managed cluster is Pending import . 1.10.11. Troubleshooting imported clusters offline after certificate change Installing a custom apiserver certificate is supported, but one or more clusters that were imported before you changed the certificate information can have an offline status. 1.10.11.1. Symptom: Clusters offline after certificate change After you complete the procedure for updating a certificate secret, one or more of your clusters that were online are now displaying an offline status in the console. 1.10.11.2. Identifying the problem: Clusters offline after certificate change After updating the information for a custom API server certificate, clusters that were imported and running before the new certificate are now in an offline state. The errors that indicate that the certificate is the problem are found in the logs for the pods in the open-cluster-management-agent namespace of the offline managed cluster. The following examples are similar to the errors that are displayed in the logs: See the following work-agent log: See the following registration-agent log: 1.10.11.3. Resolving the problem: Clusters offline after certificate change If your managed cluster is the local-cluster or your managed cluster was created by multicluster engine operator, you must wait 10 minutes or longer to recover your managed cluster. To recover your managed cluster immediately, you can delete your managed cluster import secret on the hub cluster and recover it by using multicluster engine operator. Run the following command: Replace <cluster_name> with the name of the managed cluster that you want to recover. If you want to recover a managed cluster that was imported by using multicluster engine operator, complete the following steps import the managed cluster again: On the hub cluster, recreate the managed cluster import secret by running the following command: Replace <cluster_name> with the name of the managed cluster that you want to import. On the hub cluster, expose the managed cluster import secret to a YAML file by running the following command: Replace <cluster_name> with the name of the managed cluster that you want to import. On the managed cluster, apply the import.yaml file by running the following command: Note: The steps do not detach the managed cluster from the hub cluster. The steps update the required manifests with current settings on the managed cluster, including the new certificate information. 1.10.12. Troubleshooting cluster status changing from offline to available The status of the managed cluster alternates between offline and available without any manual change to the environment or cluster. 1.10.12.1. Symptom: Cluster status changing from offline to available When the network that connects the managed cluster to the hub cluster is unstable, the status of the managed cluster that is reported by the hub cluster cycles between offline and available . 1.10.12.2. Resolving the problem: Cluster status changing from offline to available To attempt to resolve this issue, complete the following steps: Edit your ManagedCluster specification on the hub cluster by entering the following command: Replace cluster-name with the name of your managed cluster. Increase the value of leaseDurationSeconds in your ManagedCluster specification. The default value is 5 minutes, but that might not be enough time to maintain the connection with the network issues. Specify a greater amount of time for the lease. For example, you can raise the setting to 20 minutes. 1.10.13.

Check the included message for more details on the configuration errors and how to resolve them. If the PlacementSatisfied Status is false, no managed cluster satisfies your Placement . Check the included message for more details and how to resolve the error. In the example, no ManagedClusterSetBindings were found in the placement namespace. You can check the score of each cluster in Events to find out why some clusters with lower scores are not selected. The output might resemble the following example: Note: The placement controller assigns a score and generates an event for each filtered ManagedCluster . The placement controller genereates a new event when the cluster score changes. 1.10.20. Troubleshooting a discovery failure of bare metal hosts on Dell hardware If the discovery of bare metal hosts fails on Dell hardware, the Integrated Dell Remote Access Controller (iDRAC) is likely configured to not allow certificates from unknown certificate authorities. 1.10.20.1. Symptom: Discovery failure of bare metal hosts on Dell hardware After you complete the procedure for discovering bare metal hosts by using the baseboard management controller, an error message similar to the following is displayed: 1.10.20.2. Resolving the problem: Discovery failure of bare metal hosts on Dell hardware The iDRAC is configured not to accept certificates from unknown certificate authorities. To bypass the problem, disable the certificate verification on the baseboard management controller of the host iDRAC by completing the following steps: In the iDRAC console, navigate to Configuration > Virtual media > Remote file share . Change the value of Expired or invalid certificate action to Yes . 1.10.21. Troubleshooting Minimal ISO boot failures You might encounter issues when trying to boot a minimal ISO. 1.10.21.1. Symptom: Minimal ISO boot failures The boot screen shows that the host has failed to download the root file system image. 1.10.21.2. Resolving the problem: Minimal ISO boot failures See Troubleshooting minimal ISO boot failures in the Assisted Installer for OpenShift Container Platform documentation to learn how to troubleshoot the issue. 1.10.22. Troubleshooting hosted clusters on Red Hat OpenShift Virtualization When you troubleshoot a hosted cluster on Red Hat OpenShift Virtualization, start with the top-level HostedCluster and NodePool resources and then work down the stack until you find the root cause. The following steps can help you discover the root cause of common issues. 1.10.22.1. Symptom: HostedCluster resource stuck in partial state A hosted control plane is not coming fully online because a HostedCluster resource is pending. 1.10.22.1.1. Identifying the problem: Check prerequisites, resource conditions, and node and operator status Ensure that you meet all of the prerequisites for a hosted cluster on Red Hat OpenShift Virtualization View the conditions on the HostedCluster and NodePool resources for validation errors that prevent progress. By using the kubeconfig file of the hosted cluster, inspect the status of the hosted cluster: View the output of the oc get clusteroperators command to see which cluster operators are pending. View the output of the oc get nodes command to ensure that worker nodes are ready. 1.10.22.2. Symptom: No worker nodes are registered A hosted control plane is not coming fully online because the hosted control plane has no worker nodes registered. 1.10.22.2.1. Identifying the problem: Check the status of various parts of the hosted control plane View the HostedCluster and NodePool conditions for failures that indicate what the problem might be. Enter the following command to view the KubeVirt worker node virtual machine (VM) status for the NodePool resource: If the VMs are stuck in the provisioning state, enter the following command to view the CDI import pods within the VM namespace for clues about why the importer pods have not completed: If the VMs are stuck in the starting state, enter the following command to view the status of the virt-launcher pods: If the virt-launcher pods are in a pending state, investigate why the pods are not being scheduled. For example, not enough resources might exist to run the virt-launcher pods. If the VMs are running but they are not registered as worker nodes, use the web console to gain VNC access to one of the affected VMs. The VNC output indicates whether the ignition configuration was applied. If a VM cannot access the hosted control plane ignition server on startup, the VM cannot be provisioned correctly. If the ignition configuration was applied but the VM is still not registering as a node, see Identifying the problem: Access the VM console logs to learn how to access the VM console logs during startup. 1.10.22.3. Symptom: Worker nodes are stuck in the NotReady state During cluster creation, nodes enter the NotReady state temporarily while the networking stack is rolled out. This part of the process is normal. However, if this part of the process takes longer than 15 minutes, an issue might have occurred. 1.10.22.3.1. Identifying the problem: Investigate the node object and pods Enter the following command to view the conditions on the node object and determine why the node is not ready: Enter the following command to look for failing pods within the cluster: 1.10.22.4. Symptom: Ingress and console cluster operators are not coming online A hosted control plane is not coming fully online because the Ingress and console cluster operators are not online. 1.10.22.4.1. Identifying the problem: Check wildcard DNS routes and load balancer If the cluster uses the default Ingress behavior, enter the following command to ensure that wildcard DNS routes are enabled on the OpenShift Container Platform cluster that the virtual machines (VMs) are hosted on: If you use a custom base domain for the hosted control plane, complete the following steps: Ensure that the load balancer is targeting the VM pods correctly. Ensure that the wildcard DNS entry is targeting the load balancer IP. 1.10.22.5. Symptom: Load balancer services for the hosted cluster are not available A hosted control plane is not coming fully online because the load balancer services are not becoming available. 1.10.22.5.1. Identifying the problem: Check events, details, and the kccm pod Look for events and details that are associated with the load balancer service within the hosted cluster. By default, load balancers for the hosted cluster are handled by the kubevirt-cloud-controller-manager within the hosted control plane namespace. Ensure that the kccm pod is online and view its logs for errors or warnings. To identify the kccm pod in the hosted control plane namespace, enter the following command: 1.10.22.6. Symptom: Hosted cluster PVCs are not available A hosted control plane is not coming fully online because the persistent volume claims (PVCs) for a hosted cluster are not available. 1.10.22.6.1. Identifying the problem: Check PVC events and details, and component logs Look for events and details that are associated with the PVC to understand which errors are occurring. If a PVC is failing to attach to a pod, view the logs for the kubevirt-csi-node daemonset component within the hosted cluster to further investigate the problem. To identify the kubevirt-csi-node pods for each node, enter the following command: If a PVC cannot bind to a persistent volume (PV), view the logs of the kubevirt-csi-controller component within the hosted control plane namespace. To identify the kubevirt-csi-controller pod within the hosted control plane namespace, enter the following command: 1.10.22.7. Symptom: VM nodes are not correctly joining the cluster A hosted control plane is not coming fully online because the VM nodes are not correctly joining the cluster. 1.10.22.7.1. Identifying the problem: Access the VM console logs To access the VM console logs, complete the steps in How to get serial console logs for VMs part of OpenShift Virtualization Hosted Control Plane clusters . 1.10.22.8. Troubleshooting the RHCOS image mirroring For hosted control planes on Red Hat OpenShift Virtualization in a disconnected environment, oc-mirror fails to automatically mirror the Red Hat Enterprise Linux CoreOS (RHCOS) image to the internal registry. When you create your first hosted cluster, the Kubevirt virtual machine does not boot, because the boot image is not availble in the internal registry. 1.10.22.8.1. Symptom: oc-mirror fails to attempt the RHCOS image mirroring The oc-mirror plugin does not mirror the {op-system-first} image from the release payload to the internal registry. 1.10.22.8.2. Resolving the problem: oc-mirror fails to attempt the RHCOS image mirroring To resolve this issue, manually mirror the RHCOS image to the internal registry. Complete the following steps: Get the internal registry name by running the following command: oc get imagecontentsourcepolicy -o json | jq -r '.items[].spec.repositoryDigestMirrors[0].mirrors[0]' Get a payload image by running the following command: oc get clusterversion version -ojsonpath='{.status.desired.image}' Extract the 0000_50_installer_coreos-bootimages.yaml file that contains boot images from your payload image on the hosted cluster. Replace <payload_image> with the name of your payload image. Run the following command: oc image extract --file /release-manifests/0000_50_installer_coreos-bootimages.yaml <payload_image> --confirm Get the RHCOS image by running the following command: cat 0000_50_installer_coreos-bootimages.yaml | yq -r .data.stream | jq -r '.architectures.x86_64.images.kubevirt."digest-ref"' Mirror the RHCOS image to your internal registry. Replace <rhcos_image> with your RHCOS image for example, quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:d9643ead36b1c026be664c9c65c11433c6cdf71bfd93ba229141d134a4a6dd94 . Replace <internal_registry> with the name of your internal registry, for example, virthost.ostest.test.metalkube.org:5000/localimages/ocp-v4.0-art-dev . Run the following command: oc image mirror <rhcos_image> <internal_registry> Create a YAML file named rhcos-boot-kubevirt.yaml that defines the ImageDigestMirrorSet object. See the following example configuration: apiVersion: config.openshift.io/v1 kind: ImageDigestMirrorSet metadata: name: rhcos-boot-kubevirt spec: repositoryDigestMirrors: - mirrors: - <rhcos_image_no_digest> 1 source: virthost.ostest.test.metalkube.org:5000/localimages/ocp-v4.0-art-dev 2 1 Specify your RHCOS image without its digest, for example, quay.io/openshift-release-dev/ocp-v4.0-art-dev . 2 Specify the name of your internal registry, for example, virthost.ostest.test.metalkube.org:5000/localimages/ocp-v4.0-art-dev . Apply the rhcos-boot-kubevirt.yaml file to create the ImageDigestMirrorSet object by running the following command: oc apply -f rhcos-boot-kubevirt.yaml 1.10.22.9. Troubleshooting: Returning non bare metal clusters to the late binding pool If you are using late binding managed clusters without BareMetalHosts , you must complete additional manual steps to destroy a late binding cluster and return the nodes back to the Discovery ISO. 1.10.22.9.1. Symptom: Returning non bare metal clusters to the late binding pool For late binding managed clusters without BareMetalHosts , removing cluster information does not automatically return all nodes to the Discovery ISO. 1.10.22.9.2. Resolving the problem: Returning non bare metal clusters to the late binding pool To unbind the non bare metal nodes with late binding, complete the following steps: Remove the cluster information. See Removing a cluster from management to learn more. Clean the root disks. Reboot manually with the Discovery ISO. 1.10.22.10. Troubleshooting installation status stuck at Installing on a ROSA with hosted control planes cluster When you install multicluster engine for Kubernetes operator on a Red Hat OpenShift Service on AWS (ROSA) with hosted control planes cluster, multicluster engine operator becomes stuck at the Installing step and the local-cluster remains in the Unknown state. 1.10.22.10.1. Symptom: Installation status stuck at Installing on a ROSA with hosted control planes cluster The local-cluster remains in the Unknown state 10 minutes after installing multicluster engine operator. When you check the klusterlet-agent pod log in the open-cluster-management-agent namespace on your hub cluster, you see the following error message: E0809 18:45:29.450874 1 reflector.go:147] k8s.io/client-go@v0.29.4/tools/cache/reflector.go:229: Failed to watch *v1.CertificateSigningRequest: failed to list *v1.CertificateSigningRequest: Get "https://api.xxx.openshiftapps.com:443/apis/certificates.k8s.io/v1/certificatesigningrequests?limit=500&resourceVersion=0": tls: failed to verify certificate: x509: certificate signed by unknown authority 1.10.22.10.2. Resolving the problem: Installation status stuck at Installing on a ROSA with hosted control planes cluster To resolve the problem, add the ISRG Root X1 certificate to the klusterlet CA bundle by completing the following steps: Download and encode the root CA certificate by running the following command: curl -s https://letsencrypt.org/certs/isrgrootx1.pem | base64 | tr -d "\n" Create a global KlusterletConfig resource and add your encoded CA certificate to the spec parameter section. See the following example: apiVersion: config.open-cluster-management.io/v1alpha1 kind: KlusterletConfig metadata: name: global spec: hubKubeAPIServerCABundle: "<your_ca_certificate>" Apply the resource by running the following command on the hub cluster: oc apply -f <filename> If the local-cluster state does not recover in 1 minute, export and decode the import.yaml file by running the following command on the hub cluster: oc get secret local-cluster-import -n local-cluster -o jsonpath={.data.import/.yaml} | base64 --decode > import.yaml Apply the file by running the following command on the hub cluster: oc apply -f import.yaml 1.10.22.11. Troubleshooting all managed clusters become Unknown on a ROSA with hosted control planes cluster On a Red Hat OpenShift Service on AWS (ROSA) with hosted control planes cluster, the state of all managed clusters might switch to Unknown . 1.10.22.11.1. Symptom: All managed clusters become Unknown on a ROSA with hosted control planes cluster The state of all managed cluster on a ROSA hosted cluster suddenly becomes Unknown . When you check the klusterlet-agent pod log in the open-cluster-management-agent namespace on your managed cluster, you see the following error message: E0809 18:45:29.450874 1 reflector.go:147] k8s.io/client-go@v0.29.4/tools/cache/reflector.go:229: Failed to watch *v1.CertificateSigningRequest: failed to list *v1.CertificateSigningRequest: Get "https://api.xxx.openshiftapps.com:443/apis/certificates.k8s.io/v1/certificatesigningrequests?limit=500&resourceVersion=0": tls: failed to verify certificate: x509: certificate signed by unknown authority 1.10.22.11.2.

Troubleshooting an attempt to upgrade managed cluster with missing OpenShift Container Platform version You do not see the OpenShift Container Platform version that you want in the console when you attempt to upgrade your managed cluster in the console. 1.10.22.12.1. Symptom: Attempt to upgrade managed cluster with missing OpenShift Container Platform version When you attempt to upgrade a managed cluster from the console and click Upgrade available in the Cluster details view to choose the OpenShift Container Platform version from the dropdown list, the version is missing. 1.10.22.12.2. Resolving the problem: Attempt to upgrade managed cluster with missing OpenShift Container Platform version See the following procedure: Ensure the version you want is included in the status of the ClusterVersion resource on the managed cluster. Run the following command: oc get clusterversion version -o jsonpath='{.status.availableUpdates[*].version}' If your expected version is not displayed, then the version is not applicable for this managed cluster. Check if the ManagedClusterInfo resource includes the version on the hub cluster. Run the following command: oc -n <cluster_name> get managedclusterinfo <cluster_name> -o jsonpath='{.status.distributionInfo.ocp.availableUpdates[*]}' If the version is included, check to see if there is a ClusterCurator resource with a failure on the hub cluster. Run the following command: oc -n <cluster_name> get ClusterCurator <cluster_name> -o yaml If the ClusterCurator resource exists and the status of its clustercurator-job condition is False , delete the ClusterCurator resource from the hub cluster. Run the following command: oc -n <cluster_name> delete ClusterCurator <cluster_name> If the ManagedClusterInfo resource does not include the version, check the work-manager add-on log on the managed cluster and fix errors that are reported. Run the following command and replace the pod name with the real name in your environment: oc -n open-cluster-management-agent-addon logs klusterlet-addon-workmgr-<your_pod_name> 1.10.23. Troubleshooting hosted clusters on bare metal When you troubleshoot a hosted cluster on bare metal, take the following steps to discover the root cause of common issues. 1.10.23.1. Symptom: Nodes fail to be added to hosted control planes on bare metal When you scale up a hosted control planes cluster with nodes that were provisioned by using Assisted Installer, the host fails to pull the ignition with a URL that contains port 22642. That URL is invalid for hosted control planes and indicates that an issue exists with the cluster. 1.10.23.2.
