Chapter 4. Installing a cluster with customizations Use the following procedures to install an OpenShift Container Platform cluster with customizations using the Agent-based Installer. 4.1. Prerequisites You reviewed details about the OpenShift Container Platform installation and update processes. You read the documentation on selecting a cluster installation method and preparing it for users . If you use a firewall or proxy, you configured it to allow the sites that your cluster requires access to. 4.2. Installing OpenShift Container Platform with the Agent-based Installer The following procedures deploy a single-node OpenShift Container Platform in a disconnected environment. You can use these procedures as a basis and modify according to your requirements. 4.2.1. Downloading the Agent-based Installer Use this procedure to download the Agent-based Installer and the CLI needed for your installation. Note Currently, downloading the Agent-based Installer is not supported on the IBM Z(R) ( s390x ) architecture. The recommended method is by creating PXE assets. Procedure Log in to the OpenShift Container Platform web console using your login credentials. Navigate to Datacenter . Click Run Agent-based Installer locally . Select the operating system and architecture for the OpenShift Installer and Command line interface . Click Download Installer to download and extract the install program. Download or copy the pull secret by clicking on Download pull secret or Copy pull secret . Click Download command-line tools and place the openshift-install binary in a directory that is on your PATH . 4.2.2. Creating the preferred configuration inputs Use this procedure to create the preferred configuration inputs used to create the agent image. Procedure Install nmstate dependency by running the following command: USD sudo dnf install /usr/bin/nmstatectl -y Place the openshift-install binary in a directory that is on your PATH. Create a directory to store the install configuration by running the following command: USD mkdir ~/<directory_name> Note This is the preferred method for the Agent-based installation. Using GitOps ZTP manifests is optional. Create the install-config.yaml file by running the following command: USD cat << EOF > ./<directory_name>/install-config.yaml apiVersion: v1 baseDomain: test.example.com compute: - architecture: amd64 1 hyperthreading: Enabled name: worker replicas: 0 controlPlane: architecture: amd64 hyperthreading: Enabled name: master replicas: 1 metadata: name: sno-cluster 2 networking: clusterNetwork: - cidr: 10.128.0.0/14 hostPrefix: 23 machineNetwork: - cidr: 192.168.0.0/16 networkType: OVNKubernetes 3 serviceNetwork: - 172.30.0.0/16 platform: 4 none: {} pullSecret: '<pull_secret>' 5 sshKey: '<ssh_pub_key>' 6 EOF 1 Specify the system architecture, valid values are amd64 , arm64 , ppc64le , and s390x . 2 Required. Specify your cluster name. 3 The cluster network plugin to install. The default value OVNKubernetes is the only supported value. 4 Specify your platform. Note For bare metal platforms, host settings made in the platform section of the install-config.yaml file are used by default, unless they are overridden by configurations made in the agent-config.yaml file. 5 Specify your pull secret. 6 Specify your SSH public key. Note If you set the platform to vSphere or baremetal , you can configure IP address endpoints for cluster nodes in three ways: IPv4 IPv6 IPv4 and IPv6 in parallel (dual-stack) IPv6 is supported only on bare metal platforms. Example of dual-stack networking networking: clusterNetwork: - cidr: 172.21.0.0/16 hostPrefix: 23 - cidr: fd02::/48 hostPrefix: 64 machineNetwork: - cidr: 192.168.11.0/16 - cidr: 2001:DB8::/32 serviceNetwork: - 172.22.0.0/16 - fd03::/112 networkType: OVNKubernetes platform: baremetal: apiVIPs: - 192.168.11.3 - 2001:DB8::4 ingressVIPs: - 192.168.11.4 - 2001:DB8::5 Note When you use a disconnected mirror registry, you must add the certificate file that you created previously for your mirror registry to the additionalTrustBundle field of the install-config.yaml file. Create the agent-config.yaml file by running the following command: USD cat > agent-config.yaml << EOF apiVersion: v1beta1 kind: AgentConfig metadata: name: sno-cluster rendezvousIP: 192.168.111.80 1 hosts: 2 - hostname: master-0 3 interfaces: - name: eno1 macAddress: 00:ef:44:21:e6:a5 rootDeviceHints: 4 deviceName: /dev/sdb networkConfig: 5 interfaces: - name: eno1 type: ethernet state: up mac-address: 00:ef:44:21:e6:a5 ipv4: enabled: true address: - ip: 192.168.111.80 prefix-length: 23 dhcp: false dns-resolver: config: server: - 192.168.111.1 routes: config: - destination: 0.0.0.0/0 -hop-address: 192.168.111.2 -hop-interface: eno1 table-id: 254 EOF 1 This IP address is used to determine which node performs the bootstrapping process as well as running the assisted-service component. You must provide the rendezvous IP address when you do not specify at least one host's IP address in the networkConfig parameter. If this address is not provided, one IP address is selected from the provided hosts' networkConfig . 2 Optional: Host configuration. The number of hosts defined must not exceed the total number of hosts defined in the install-config.yaml file, which is the sum of the values of the compute.replicas and controlPlane.replicas parameters. 3 Optional: Overrides the hostname obtained from either the Dynamic Host Configuration Protocol (DHCP) or a reverse DNS lookup. Each host must have a unique hostname supplied by one of these methods. 4 Enables provisioning of the Red Hat Enterprise Linux CoreOS (RHCOS) image to a particular device. The installation program examines the devices in the order it discovers them, and compares the discovered values with the hint values. It uses the first discovered device that matches the hint value. 5 Optional: Configures the network interface of a host in NMState format. Additional resources Configuring regions and zones for a VMware vCenter Configuring the Agent-based Installer to use mirrored images 4.2.3. Creating additional manifest files As an optional task, you can create additional manifests to further configure your cluster beyond the configurations available in the install-config.yaml and agent-config.yaml files. Important Customizations to the cluster made by additional manifests are not validated, are not guaranteed to work, and might result in a nonfunctional cluster. 4.2.3.1. Creating a directory to contain additional manifests If you create additional manifests to configure your Agent-based installation beyond the install-config.yaml and agent-config.yaml files, you must create an openshift subdirectory within your installation directory. All of your additional machine configurations must be located within this subdirectory. Note The most common type of additional manifest you can add is a MachineConfig object. For examples of MachineConfig objects you can add during the Agent-based installation, see "Using MachineConfig objects to configure nodes" in the "Additional resources" section. Procedure On your installation host, create an openshift subdirectory within the installation directory by running the following command: USD mkdir <installation_directory>/openshift Additional resources Using MachineConfig objects to configure nodes 4.2.3.2. Disk partitioning In general, you should use the default disk partitioning that is created during the RHCOS installation. However, there are cases where you might want to create a separate partition for a directory that you expect to grow. OpenShift Container Platform supports the addition of a single partition to attach storage to either the /var directory or a subdirectory of /var . For example: /var/lib/containers : Holds container-related content that can grow as more images and containers are added to a system. /var/lib/etcd : Holds data that you might want to keep separate for purposes such as performance optimization of etcd storage. /var : Holds data that you might want to keep separate for purposes such as auditing. Important For disk sizes larger than 100GB, and especially larger than 1TB, create a separate /var partition. Storing the contents of a /var directory separately makes it easier to grow storage for those areas as needed and reinstall OpenShift Container Platform at a later date and keep that data intact. With this method, you will not have to pull all your containers again, nor will you have to copy massive log files when you update systems. The use of a separate partition for the /var directory or a subdirectory of /var also prevents data growth in the partitioned directory from filling up the root file system. The following procedure sets up a separate /var partition by adding a machine config manifest that is wrapped into the Ignition config file for a node type during the preparation phase of an installation. Prerequisites You have created an openshift subdirectory within your installation directory. Procedure Create a Butane config that configures the additional partition. For example, name the file USDHOME/clusterconfig/98-var-partition.bu , change the disk device name to the name of the storage device on the worker systems, and set the storage size as appropriate. This example places the /var directory on a separate partition: variant: openshift version: 4.15.0 metadata: labels: machineconfiguration.openshift.io/role: worker name: 98-var-partition storage: disks: - device: /dev/disk/by-id/<device_name> 1 partitions: - label: var start_mib: <partition_start_offset> 2 size_mib: <partition_size> 3 number: 5 filesystems: - device: /dev/disk/by-partlabel/var path: /var format: xfs mount_options: [defaults, prjquota] 4 with_mount_unit: true 1 The storage device name of the disk that you want to partition. 2 When adding a data partition to the boot disk, a minimum offset value of 25000 mebibytes is recommended. The root file system is automatically resized to fill all available space up to the specified offset. If no offset value is specified, or if the specified value is smaller than the recommended minimum, the resulting root file system will be too small, and future reinstalls of RHCOS might overwrite the beginning of the data partition. 3 The size of the data partition in mebibytes. 4 The prjquota mount option must be enabled for filesystems used for container storage. Note When creating a separate /var partition, you cannot use different instance types for compute nodes, if the different instance types do not have the same device name. Create a manifest from the Butane config and save it to the clusterconfig/openshift directory. For example, run the following command: USD butane USDHOME/clusterconfig/98-var-partition.bu -o USDHOME/clusterconfig/openshift/98-var-partition.yaml 4.2.4. Using ZTP manifests As an optional task, you can use GitOps Zero Touch Provisioning (ZTP) manifests to configure your installation beyond the options available through the install-config.yaml and agent-config.yaml files. Note GitOps ZTP manifests can be generated with or without configuring the install-config.yaml and agent-config.yaml files beforehand. If you chose to configure the install-config.yaml and agent-config.yaml files, the configurations will be imported to the ZTP cluster manifests when they are generated. Prerequisites You have placed the openshift-install binary in a directory that is on your PATH . Optional: You have created and configured the install-config.yaml and agent-config.yaml files. Procedure Generate ZTP cluster manifests by running the following command: USD openshift-install agent create cluster-manifests --dir <installation_directory> Important If you have created the install-config.yaml and agent-config.yaml files, those files are deleted and replaced by the cluster manifests generated through this command. Any configurations made to the install-config.yaml and agent-config.yaml files are imported to the ZTP cluster manifests when you run the openshift-install agent create cluster-manifests command. Navigate to the cluster-manifests directory by running the following command: USD cd <installation_directory>/cluster-manifests Configure the manifest files in the cluster-manifests directory. For sample files, see the "Sample GitOps ZTP custom resources" section. Disconnected clusters: If you did not define mirror configuration in the install-config.yaml file before generating the ZTP manifests, perform the following steps: Navigate to the mirror directory by running the following command: USD cd ../mirror Configure the manifest files in the mirror directory. Additional resources Sample GitOps ZTP custom resources . See Challenges of the network far edge to learn more about GitOps Zero Touch Provisioning (ZTP). 4.2.5. Encrypting the disk As an optional task, you can use this procedure to encrypt your disk or partition while installing OpenShift Container Platform with the Agent-based Installer. Prerequisites You have created and configured the install-config.yaml and agent-config.yaml files, unless you are using ZTP manifests. You have placed the openshift-install binary in a directory that is on your PATH . Procedure Generate ZTP cluster manifests by running the following command: USD openshift-install agent create cluster-manifests --dir <installation_directory> Important If you have created the install-config.yaml and agent-config.yaml files, those files are deleted and replaced by the cluster manifests generated through this command. Any configurations made to the install-config.yaml and agent-config.yaml files are imported to the ZTP cluster manifests when you run the openshift-install agent create cluster-manifests command. Note If you have already generated ZTP manifests, skip this step. Navigate to the cluster-manifests directory by running the following command: USD cd <installation_directory>/cluster-manifests Add the following section to the agent-cluster-install.yaml file: diskEncryption: enableOn: all 1 mode: tang 2 tangServers: "server1": "http://tang-server-1.example.com:7500" 3 1 Specify which nodes to enable disk encryption on. Valid values are none , all , master , and worker . 2 Specify which disk encryption mode to use. Valid values are tpmv2 and tang . 3 Optional: If you are using Tang, specify the Tang servers. Additional resources About disk encryption 4.2.6. Creating and booting the agent image Use this procedure to boot the agent image on your machines. Procedure Create the agent image by running the following command: USD openshift-install --dir <install_directory> agent create image Note Red Hat Enterprise Linux CoreOS (RHCOS) supports multipathing on the primary disk, allowing stronger resilience to hardware failure to achieve higher host availability. Multipathing is enabled by default in the agent ISO image, with a default /etc/multipath.conf configuration. Boot the agent.x86_64.iso or agent.aarch64.iso image on the bare metal machines. 4.2.7. Verifying that the current installation host can pull release images After you boot the agent image and network services are made available to the host, the agent console application performs a pull check to verify that the current host can retrieve release images. If the primary pull check passes, you can quit the application to continue with the installation. If the pull check fails, the application performs additional checks, as seen in the Additional checks section of the TUI, to help you troubleshoot the problem. A failure for any of the additional checks is not necessarily critical as long as the primary pull check succeeds. If there are host network configuration issues that might cause an installation to fail, you can use the console application to make adjustments to your network configurations. Important If the agent console application detects host network configuration issues, the installation workflow will be halted until the user manually stops the console application and signals the intention to proceed. Procedure Wait for the agent console application to check whether or not the configured release image can be pulled from a registry. If the agent console application states that the installer connectivity checks have passed, wait for the prompt to time out to continue with the installation. Note You can still choose to view or change network configuration settings even if the connectivity checks have passed. However, if you choose to interact with the agent console application rather than letting it time out, you must manually quit the TUI to proceed with the installation. If the agent console application checks have failed, which is indicated by a red icon beside the Release image URL pull check, use the following steps to reconfigure the host's network settings: Read the Check Errors section of the TUI. This section displays error messages specific to the failed checks. Select Configure network to launch the NetworkManager TUI. Select Edit a connection and select the connection you want to reconfigure. Edit the configuration and select OK to save your changes. Select Back to return to the main screen of the NetworkManager TUI. Select Activate a Connection . Select the reconfigured network to deactivate it. Select the reconfigured network again to reactivate it. Select Back and then select Quit to return to the agent console application. Wait at least five seconds for the continuous network checks to restart using the new network configuration. If the Release image URL pull check succeeds and displays a green icon beside the URL, select Quit to exit the agent console application and continue with the installation. 4.2.8. Tracking and verifying installation progress Use the following procedure to track installation progress and to verify a successful installation. Prerequisites You have configured a DNS record for the Kubernetes API server. Procedure Optional: To know when the bootstrap host (rendezvous host) reboots, run the following command: USD ./openshift-install --dir <install_directory> agent wait-for bootstrap-complete \ 1 --log-level=info 2 1 For <install_directory> , specify the path to the directory where the agent ISO was generated. 2 To view different installation details, specify warn , debug , or error instead of info . Example output ................................................................... ................................................................... INFO Bootstrap configMap status is complete INFO cluster bootstrap is complete The command succeeds when the Kubernetes API server signals that it has been bootstrapped on the control plane machines. To track the progress and verify successful installation, run the following command: USD openshift-install --dir <install_directory> agent wait-for install-complete 1 1 For <install_directory> directory, specify the path to the directory where the agent ISO was generated. Example output ................................................................... ................................................................... INFO Cluster is installed INFO Install complete! INFO To access the cluster as the system:admin user when using 'oc', run INFO export KUBECONFIG=/home/core/installer/auth/kubeconfig INFO Access the OpenShift web-console here: https://console-openshift-console.apps.sno-cluster.test.example.com Note If you are using the optional method of GitOps ZTP manifests, you can configure IP address endpoints for cluster nodes through the AgentClusterInstall.yaml file in three ways: IPv4 IPv6 IPv4 and IPv6 in parallel (dual-stack) IPv6 is supported only on bare metal platforms.

Sample GitOps ZTP custom resources You can optionally use GitOps Zero Touch Provisioning (ZTP) custom resource (CR) objects to install an OpenShift Container Platform cluster with the Agent-based Installer. You can customize the following GitOps ZTP custom resources to specify more details about your OpenShift Container Platform cluster. The following sample GitOps ZTP custom resources are for a single-node cluster. Example agent-cluster-install.yaml file apiVersion: extensions.hive.openshift.io/v1beta1 kind: AgentClusterInstall metadata: name: test-agent-cluster-install namespace: cluster0 spec: clusterDeploymentRef: name: ostest imageSetRef: name: openshift-4.15 networking: clusterNetwork: - cidr: 10.128.0.0/14 hostPrefix: 23 serviceNetwork: - 172.30.0.0/16 provisionRequirements: controlPlaneAgents: 1 workerAgents: 0 sshPublicKey: <ssh_public_key> Example cluster-deployment.yaml file apiVersion: hive.openshift.io/v1 kind: ClusterDeployment metadata: name: ostest namespace: cluster0 spec: baseDomain: test.metalkube.org clusterInstallRef: group: extensions.hive.openshift.io kind: AgentClusterInstall name: test-agent-cluster-install version: v1beta1 clusterName: ostest controlPlaneConfig: servingCertificates: {} platform: agentBareMetal: agentSelector: matchLabels: bla: aaa pullSecretRef: name: pull-secret Example cluster-image-set.yaml file apiVersion: hive.openshift.io/v1 kind: ClusterImageSet metadata: name: openshift-4.15 spec: releaseImage: registry.ci.openshift.org/ocp/release:4.15.0-0.nightly-2022-06-06-025509 Example infra-env.yaml file apiVersion: agent-install.openshift.io/v1beta1 kind: InfraEnv metadata: name: myinfraenv namespace: cluster0 spec: clusterRef: name: ostest namespace: cluster0 cpuArchitecture: aarch64 pullSecretRef: name: pull-secret sshAuthorizedKey: <ssh_public_key> nmStateConfigLabelSelector: matchLabels: cluster0-nmstate-label-name: cluster0-nmstate-label-value Example nmstateconfig.yaml file apiVersion: agent-install.openshift.io/v1beta1 kind: NMStateConfig metadata: name: master-0 namespace: openshift-machine-api labels: cluster0-nmstate-label-name: cluster0-nmstate-label-value spec: config: interfaces: - name: eth0 type: ethernet state: up mac-address: 52:54:01:aa:aa:a1 ipv4: enabled: true address: - ip: 192.168.122.2 prefix-length: 23 dhcp: false dns-resolver: config: server: - 192.168.122.1 routes: config: - destination: 0.0.0.0/0 -hop-address: 192.168.122.1 -hop-interface: eth0 table-id: 254 interfaces: - name: "eth0" macAddress: 52:54:01:aa:aa:a1 Example pull-secret.yaml file apiVersion: v1 kind: Secret type: kubernetes.io/dockerconfigjson metadata: name: pull-secret namespace: cluster0 stringData: .dockerconfigjson: <pull_secret> Additional resources See Challenges of the network far edge to learn more about GitOps Zero Touch Provisioning (ZTP). 4.4. Gathering log data from a failed Agent-based installation Use the following procedure to gather log data about a failed Agent-based installation to provide for a support case. Prerequisites You have configured a DNS record for the Kubernetes API server. Procedure Run the following command and collect the output: USD ./openshift-install --dir <installation_directory> agent wait-for bootstrap-complete --log-level=debug Example error message ... ERROR Bootstrap failed to complete: : bootstrap process timed out: context deadline exceeded If the output from the command indicates a failure, or if the bootstrap is not progressing, run the following command to connect to the rendezvous host and collect the output: USD ssh core@<node-ip> agent-gather -O >agent-gather.tar.xz Note Red Hat Support can diagnose most issues using the data gathered from the rendezvous host, but if some hosts are not able to register, gathering this data from every host might be helpful. If the bootstrap completes and the cluster nodes reboot, run the following command and collect the output: USD ./openshift-install --dir <install_directory> agent wait-for install-complete --log-level=debug If the output from the command indicates a failure, perform the following steps: Export the kubeconfig file to your environment by running the following command: USD export KUBECONFIG=<install_directory>/auth/kubeconfig Gather information for debugging by running the following command: USD oc adm must-gather Create a compressed file from the must-gather directory that was just created in your working directory by running the following command: USD tar cvaf must-gather.tar.gz <must_gather_directory> Excluding the /auth subdirectory, attach the installation directory used during the deployment to your support case on the Red Hat Customer Portal . Attach all other data gathered from this procedure to your support case.
