Chapter 4. Administrator tasks 4.1. Adding Operators to a cluster Cluster administrators can install Operators to an OpenShift Container Platform cluster by subscribing Operators to namespaces with OperatorHub. Note For information on how OLM handles updates for installed Operators colocated in the same namespace, as well as an alternative method for installing Operators with custom global Operator groups, see Multitenancy and Operator colocation . 4.1.1. About Operator installation with OperatorHub OperatorHub is a user interface for discovering Operators; it works in conjunction with Operator Lifecycle Manager (OLM), which installs and manages Operators on a cluster. As a user with the proper permissions, you can install an Operator from OperatorHub using the OpenShift Container Platform web console or CLI. During installation, you must determine the following initial settings for the Operator: Installation Mode Choose a specific namespace in which to install the Operator. Update Channel If an Operator is available through multiple channels, you can choose which channel you want to subscribe to. For example, to deploy from the stable channel, if available, select it from the list. Approval Strategy You can choose automatic or manual updates. If you choose automatic updates for an installed Operator, when a new version of that Operator is available in the selected channel, Operator Lifecycle Manager (OLM) automatically upgrades the running instance of your Operator without human intervention. If you select manual updates, when a newer version of an Operator is available, OLM creates an update request. As a cluster administrator, you must then manually approve that update request to have the Operator updated to the new version. Additional resources Understanding OperatorHub 4.1.2. Installing from OperatorHub using the web console You can install and subscribe to an Operator from OperatorHub using the OpenShift Container Platform web console. Prerequisites Access to an OpenShift Container Platform cluster using an account with cluster-admin permissions. Access to an OpenShift Container Platform cluster using an account with Operator installation permissions. Procedure Navigate in the web console to the Operators OperatorHub page. Scroll or type a keyword into the Filter by keyword box to find the Operator you want. For example, type advanced to find the Advanced Cluster Management for Kubernetes Operator. You can also filter options by Infrastructure Features . For example, select Disconnected if you want to see Operators that work in disconnected environments, also known as restricted network environments. Select the Operator to display additional information. Note Choosing a Community Operator warns that Red Hat does not certify Community Operators; you must acknowledge the warning before continuing. Read the information about the Operator and click Install . On the Install Operator page: Select one of the following: All namespaces on the cluster (default) installs the Operator in the default openshift-operators namespace to watch and be made available to all namespaces in the cluster. This option is not always available. A specific namespace on the cluster allows you to choose a specific, single namespace in which to install the Operator. The Operator will only watch and be made available for use in this single namespace. Choose a specific, single namespace in which to install the Operator. The Operator will only watch and be made available for use in this single namespace. Select an Update Channel (if more than one is available). Select Automatic or Manual approval strategy, as described earlier. Click Install to make the Operator available to the selected namespaces on this OpenShift Container Platform cluster. If you selected a Manual approval strategy, the upgrade status of the subscription remains Upgrading until you review and approve the install plan. After approving on the Install Plan page, the subscription upgrade status moves to Up to date . If you selected an Automatic approval strategy, the upgrade status should resolve to Up to date without intervention. After the upgrade status of the subscription is Up to date , select Operators Installed Operators to verify that the cluster service version (CSV) of the installed Operator eventually shows up. The Status should ultimately resolve to InstallSucceeded in the relevant namespace. Note For the All namespaces... installation mode, the status resolves to InstallSucceeded in the openshift-operators namespace, but the status is Copied if you check in other namespaces. If it does not: Check the logs in any pods in the openshift-operators project (or other relevant namespace if A specific namespace... installation mode was selected) on the Workloads Pods page that are reporting issues to troubleshoot further. 4.1.3. Installing from OperatorHub using the CLI Instead of using the OpenShift Container Platform web console, you can install an Operator from OperatorHub using the CLI. Use the oc command to create or update a Subscription object. Prerequisites Access to an OpenShift Container Platform cluster using an account with Operator installation permissions. Install the oc command to your local system. Procedure View the list of Operators available to the cluster from OperatorHub: USD oc get packagemanifests -n openshift-marketplace Example output NAME CATALOG AGE 3scale-operator Red Hat Operators 91m advanced-cluster-management Red Hat Operators 91m amq7-cert-manager Red Hat Operators 91m ... couchbase-enterprise-certified Certified Operators 91m crunchy-postgres-operator Certified Operators 91m mongodb-enterprise Certified Operators 91m ... etcd Community Operators 91m jaeger Community Operators 91m kubefed Community Operators 91m ... Note the catalog for your desired Operator. Inspect your desired Operator to verify its supported install modes and available channels: USD oc describe packagemanifests <operator_name> -n openshift-marketplace An Operator group, defined by an OperatorGroup object, selects target namespaces in which to generate required RBAC access for all Operators in the same namespace as the Operator group. The namespace to which you subscribe the Operator must have an Operator group that matches the install mode of the Operator, either the AllNamespaces or SingleNamespace mode. If the Operator you intend to install uses the AllNamespaces , then the openshift-operators namespace already has an appropriate Operator group in place. However, if the Operator uses the SingleNamespace mode and you do not already have an appropriate Operator group in place, you must create one. Note The web console version of this procedure handles the creation of the OperatorGroup and Subscription objects automatically behind the scenes for you when choosing SingleNamespace mode. Create an OperatorGroup object YAML file, for example operatorgroup.yaml : Example OperatorGroup object apiVersion: operators.coreos.com/v1 kind: OperatorGroup metadata: name: <operatorgroup_name> namespace: <namespace> spec: targetNamespaces: - <namespace> Warning Operator Lifecycle Manager (OLM) creates the following cluster roles for each Operator group: <operatorgroup_name>-admin <operatorgroup_name>-edit <operatorgroup_name>-view When you manually create an Operator group, you must specify a unique name that does not conflict with the existing cluster roles or other Operator groups on the cluster. Create the OperatorGroup object: USD oc apply -f operatorgroup.yaml Create a Subscription object YAML file to subscribe a namespace to an Operator, for example sub.yaml : Example Subscription object apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: name: <subscription_name> namespace: openshift-operators 1 spec: channel: <channel_name> 2 name: <operator_name> 3 source: redhat-operators 4 sourceNamespace: openshift-marketplace 5 config: env: 6 - name: ARGS value: "-v=10" envFrom: 7 - secretRef: name: license-secret volumes: 8 - name: <volume_name> configMap: name: <configmap_name> volumeMounts: 9 - mountPath: <directory_name> name: <volume_name> tolerations: 10 - operator: "Exists" resources: 11 requests: memory: "64Mi" cpu: "250m" limits: memory: "128Mi" cpu: "500m" nodeSelector: 12 foo: bar 1 For default AllNamespaces install mode usage, specify the openshift-operators namespace. Alternatively, you can specify a custom global namespace, if you have created one. Otherwise, specify the relevant single namespace for SingleNamespace install mode usage. 2 Name of the channel to subscribe to. 3 Name of the Operator to subscribe to. 4 Name of the catalog source that provides the Operator. 5 Namespace of the catalog source. Use openshift-marketplace for the default OperatorHub catalog sources. 6 The env parameter defines a list of Environment Variables that must exist in all containers in the pod created by OLM. 7 The envFrom parameter defines a list of sources to populate Environment Variables in the container. 8 The volumes parameter defines a list of Volumes that must exist on the pod created by OLM. 9 The volumeMounts parameter defines a list of VolumeMounts that must exist in all containers in the pod created by OLM. If a volumeMount references a volume that does not exist, OLM fails to deploy the Operator. 10 The tolerations parameter defines a list of Tolerations for the pod created by OLM. 11 The resources parameter defines resource constraints for all the containers in the pod created by OLM. 12 The nodeSelector parameter defines a NodeSelector for the pod created by OLM. Create the Subscription object: USD oc apply -f sub.yaml At this point, OLM is now aware of the selected Operator. A cluster service version (CSV) for the Operator should appear in the target namespace, and APIs provided by the Operator should be available for creation. Additional resources About Operator groups 4.1.4. Installing a specific version of an Operator You can install a specific version of an Operator by setting the cluster service version (CSV) in a Subscription object. Prerequisites Access to an OpenShift Container Platform cluster using an account with Operator installation permissions OpenShift CLI ( oc ) installed Procedure Create a Subscription object YAML file that subscribes a namespace to an Operator with a specific version by setting the startingCSV field. Set the installPlanApproval field to Manual to prevent the Operator from automatically upgrading if a later version exists in the catalog. For example, the following sub.yaml file can be used to install the Red Hat Quay Operator specifically to version 3.4.0: Subscription with a specific starting Operator version apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: name: quay-operator namespace: quay spec: channel: quay-v3.4 installPlanApproval: Manual 1 name: quay-operator source: redhat-operators sourceNamespace: openshift-marketplace startingCSV: quay-operator.v3.4.0 2 1 Set the approval strategy to Manual in case your specified version is superseded by a later version in the catalog. This plan prevents an automatic upgrade to a later version and requires manual approval before the starting CSV can complete the installation. 2 Set a specific version of an Operator CSV. Create the Subscription object: USD oc apply -f sub.yaml Manually approve the pending install plan to complete the Operator installation. Additional resources Manually approving a pending Operator update 4.1.5. Preparing for multiple instances of an Operator for multitenant clusters As a cluster administrator, you can add multiple instances of an Operator for use in multitenant clusters. This is an alternative solution to either using the standard All namespaces install mode, which can be considered to violate the principle of least privilege, or the Multinamespace mode, which is not widely adopted. For more information, see "Operators in multitenant clusters". In the following procedure, the tenant is a user or group of users that share common access and privileges for a set of deployed workloads. The tenant Operator is the instance of an Operator that is intended for use by only that tenant. Prerequisites All instances of the Operator you want to install must be the same version across a given cluster. Important For more information on this and other limitations, see "Operators in multitenant clusters". Procedure Before installing the Operator, create a namespace for the tenant Operator that is separate from the tenant's namespace. For example, if the tenant's namespace is team1 , you might create a team1-operator namespace: Define a Namespace resource and save the YAML file, for example, team1-operator.yaml : apiVersion: v1 kind: Namespace metadata: name: team1-operator Create the namespace by running the following command: USD oc create -f team1-operator.yaml Create an Operator group for the tenant Operator scoped to the tenant's namespace, with only that one namespace entry in the spec.targetNamespaces list: Define an OperatorGroup resource and save the YAML file, for example, team1-operatorgroup.yaml : apiVersion: operators.coreos.com/v1 kind: OperatorGroup metadata: name: team1-operatorgroup namespace: team1-operator spec: targetNamespaces: - team1 1 1 Define only the tenant's namespace in the spec.targetNamespaces list. Create the Operator group by running the following command: USD oc create -f team1-operatorgroup.yaml steps Install the Operator in the tenant Operator namespace. This task is more easily performed by using the OperatorHub in the web console instead of the CLI; for a detailed procedure, see Installing from OperatorHub using the web console . Note After completing the Operator installation, the Operator resides in the tenant Operator namespace and watches the tenant namespace, but neither the Operator's pod nor its service account are visible or usable by the tenant. Additional resources Operators in multitenant clusters 4.1.6. Installing global Operators in custom namespaces When installing Operators with the OpenShift Container Platform web console, the default behavior installs Operators that support the All namespaces install mode into the default openshift-operators global namespace. This can cause issues related to shared install plans and update policies between all Operators in the namespace. For more details on these limitations, see "Multitenancy and Operator colocation". As a cluster administrator, you can bypass this default behavior manually by creating a custom global namespace and using that namespace to install your individual or scoped set of Operators and their dependencies. Procedure Before installing the Operator, create a namespace for the installation of your desired Operator. This installation namespace will become the custom global namespace: Define a Namespace resource and save the YAML file, for example, global-operators.yaml : apiVersion: v1 kind: Namespace metadata: name: global-operators Create the namespace by running the following command: USD oc create -f global-operators.yaml Create a custom global Operator group , which is an Operator group that watches all namespaces: Define an OperatorGroup resource and save the YAML file, for example, global-operatorgroup.yaml . Omit both the spec.selector and spec.targetNamespaces fields to make it a global Operator group , which selects all namespaces: apiVersion: operators.coreos.com/v1 kind: OperatorGroup metadata: name: global-operatorgroup namespace: global-operators Note The status.namespaces of a created global Operator group contains the empty string ( "" ), which signals to a consuming Operator that it should watch all namespaces. Create the Operator group by running the following command: USD oc create -f global-operatorgroup.yaml steps Install the desired Operator in your custom global namespace. Because the web console does not populate the Installed Namespace menu during Operator installation with custom global namespaces, this task can only be performed with the OpenShift CLI ( oc ). For a detailed procedure, see Installing from OperatorHub using the CLI . Note When you initiate the Operator installation, if the Operator has dependencies, the dependencies are also automatically installed in the custom global namespace. As a result, it is then valid for the dependency Operators to have the same update policy and shared install plans. Additional resources Multitenancy and Operator colocation 4.1.7. Pod placement of Operator workloads By default, Operator Lifecycle Manager (OLM) places pods on arbitrary worker nodes when installing an Operator or deploying Operand workloads. As an administrator, you can use projects with a combination of node selectors, taints, and tolerations to control the placement of Operators and Operands to specific nodes. Controlling pod placement of Operator and Operand workloads has the following prerequisites: Determine a node or set of nodes to target for the pods per your requirements. If available, note an existing label, such as node-role.kubernetes.io/app , that identifies the node or nodes. Otherwise, add a label, such as myoperator , by using a machine set or editing the node directly. You will use this label in a later step as the node selector on your project. If you want to ensure that only pods with a certain label are allowed to run on the nodes, while steering unrelated workloads to other nodes, add a taint to the node or nodes by using a machine set or editing the node directly. Use an effect that ensures that new pods that do not match the taint cannot be scheduled on the nodes. For example, a myoperator:NoSchedule taint ensures that new pods that do not match the taint are not scheduled onto that node, but existing pods on the node are allowed to remain. Create a project that is configured with a default node selector and, if you added a taint, a matching toleration. At this point, the project you created can be used to steer pods towards the specified nodes in the following scenarios: For Operator pods Administrators can create a Subscription object in the project. As a result, the Operator pods are placed on the specified nodes. For Operand pods Using an installed Operator, users can create an application in the project, which places the custom resource (CR) owned by the Operator in the project. As a result, the Operand pods are placed on the specified nodes, unless the Operator is deploying cluster-wide objects or resources in other namespaces, in which case this customized pod placement does not apply. Additional resources Adding taints and tolerations manually to nodes or with machine sets Creating project-wide node selectors Creating a project with a node selector and toleration 4.2. Updating installed Operators As a cluster administrator, you can update Operators that have been previously installed using Operator Lifecycle Manager (OLM) on your OpenShift Container Platform cluster. Note For information on how OLM handles updates for installed Operators colocated in the same namespace, as well as an alternative method for installing Operators with custom global Operator groups, see Multitenancy and Operator colocation . 4.2.1. Preparing for an Operator update The subscription of an installed Operator specifies an update channel that tracks and receives updates for the Operator. You can change the update channel to start tracking and receiving updates from a newer channel. The names of update channels in a subscription can differ between Operators, but the naming scheme typically follows a common convention within a given Operator. For example, channel names might follow a minor release update stream for the application provided by the Operator ( 1.2 , 1.3 ) or a release frequency ( stable , fast ). Note You cannot change installed Operators to a channel that is older than the current channel. Red Hat Customer Portal Labs include the following application that helps administrators prepare to update their Operators: Red Hat OpenShift Container Platform Operator Update Information Checker You can use the application to search for Operator Lifecycle Manager-based Operators and verify the available Operator version per update channel across different versions of OpenShift Container Platform. Cluster Version Operator-based Operators are not included. 4.2.2. Changing the update channel for an Operator You can change the update channel for an Operator by using the OpenShift Container Platform web console. Tip If the approval strategy in the subscription is set to Automatic , the update process initiates as soon as a new Operator version is available in the selected channel. If the approval strategy is set to Manual , you must manually approve pending updates. Prerequisites An Operator previously installed using Operator Lifecycle Manager (OLM). Procedure In the Administrator perspective of the web console, navigate to Operators Installed Operators . Click the name of the Operator you want to change the update channel for. Click the Subscription tab. Click the name of the update channel under Channel . Click the newer update channel that you want to change to, then click Save . For subscriptions with an Automatic approval strategy, the update begins automatically. Navigate back to the Operators Installed Operators page to monitor the progress of the update. When complete, the status changes to Succeeded and Up to date . For subscriptions with a Manual approval strategy, you can manually approve the update from the Subscription tab. 4.2.3. Manually approving a pending Operator update If an installed Operator has the approval strategy in its subscription set to Manual , when new updates are released in its current update channel, the update must be manually approved before installation can begin. Prerequisites An Operator previously installed using Operator Lifecycle Manager (OLM). Procedure In the Administrator perspective of the OpenShift Container Platform web console, navigate to Operators Installed Operators . Operators that have a pending update display a status with Upgrade available . Click the name of the Operator you want to update. Click the Subscription tab. Any update requiring approval are displayed to Upgrade Status . For example, it might display 1 requires approval . Click 1 requires approval , then click Preview Install Plan . Review the resources that are listed as available for update. When satisfied, click Approve . Navigate back to the Operators Installed Operators page to monitor the progress of the update. When complete, the status changes to Succeeded and Up to date . 4.3. Deleting Operators from a cluster The following describes how to delete, or uninstall, Operators that were previously installed using Operator Lifecycle Manager (OLM) on your OpenShift Container Platform cluster. Important You must successfully and completely uninstall an Operator prior to attempting to reinstall the same Operator. Failure to fully uninstall the Operator properly can leave resources, such as a project or namespace, stuck in a "Terminating" state and cause "error resolving resource" messages to be observed when trying to reinstall the Operator. For more information, see Reinstalling Operators after failed uninstallation . 4.3.1. Deleting Operators from a cluster using the web console Cluster administrators can delete installed Operators from a selected namespace by using the web console. Prerequisites You have access to an OpenShift Container Platform cluster web console using an account with cluster-admin permissions. Procedure Navigate to the Operators Installed Operators page. Scroll or enter a keyword into the Filter by name field to find the Operator that you want to remove. Then, click on it. On the right side of the Operator Details page, select Uninstall Operator from the Actions list. An Uninstall Operator? dialog box is displayed. Select Uninstall to remove the Operator, Operator deployments, and pods. Following this action, the Operator stops running and no longer receives updates. Note This action does not remove resources managed by the Operator, including custom resource definitions (CRDs) and custom resources (CRs). Dashboards and navigation items enabled by the web console and off-cluster resources that continue to run might need manual clean up. To remove these after uninstalling the Operator, you might need to manually delete the Operator CRDs. 4.3.2. Deleting Operators from a cluster using the CLI Cluster administrators can delete installed Operators from a selected namespace by using the CLI. Prerequisites Access to an OpenShift Container Platform cluster using an account with cluster-admin permissions. oc command installed on workstation. Procedure Ensure the latest version of the subscribed operator (for example, serverless-operator ) is identified in the currentCSV field. USD oc get subscription.operators.coreos.com serverless-operator -n openshift-serverless -o yaml | grep currentCSV Example output currentCSV: serverless-operator.v1.28.0 Delete the subscription (for example, serverless-operator ): USD oc delete subscription.operators.coreos.com serverless-operator -n openshift-serverless Example output subscription.operators.coreos.com "serverless-operator" deleted Delete the CSV for the Operator in the target namespace using the currentCSV value from the step: USD oc delete clusterserviceversion serverless-operator.v1.28.0 -n openshift-serverless Example output clusterserviceversion.operators.coreos.com "serverless-operator.v1.28.0" deleted 4.3.3. Refreshing failing subscriptions In Operator Lifecycle Manager (OLM), if you subscribe to an Operator that references images that are not accessible on your network, you can find jobs in the openshift-marketplace namespace that are failing with the following errors: Example output ImagePullBackOff for Back-off pulling image "example.com/openshift4/ose-elasticsearch-operator-bundle@sha256:6d2587129c846ec28d384540322b40b05833e7e00b25cca584e004af9a1d292e" Example output rpc error: code = Unknown desc = error pinging docker registry example.com: Get "https://example.com/v2/": dial tcp: lookup example.com on 10.0.0.1:53: no such host As a result, the subscription is stuck in this failing state and the Operator is unable to install or upgrade. You can refresh a failing subscription by deleting the subscription, cluster service version (CSV), and other related objects. After recreating the subscription, OLM then reinstalls the correct version of the Operator. Prerequisites You have a failing subscription that is unable to pull an inaccessible bundle image. You have confirmed that the correct bundle image is accessible. Procedure Get the names of the Subscription and ClusterServiceVersion objects from the namespace where the Operator is installed: USD oc get sub,csv -n <namespace> Example output NAME PACKAGE SOURCE CHANNEL subscription.operators.coreos.com/elasticsearch-operator elasticsearch-operator redhat-operators 5.0 NAME DISPLAY VERSION REPLACES PHASE clusterserviceversion.operators.coreos.com/elasticsearch-operator.5.0.0-65 OpenShift Elasticsearch Operator 5.0.0-65 Succeeded Delete the subscription: USD oc delete subscription <subscription_name> -n <namespace> Delete the cluster service version: USD oc delete csv <csv_name> -n <namespace> Get the names of any failing jobs and related config maps in the openshift-marketplace namespace: USD oc get job,configmap -n openshift-marketplace Example output NAME COMPLETIONS DURATION AGE job.batch/1de9443b6324e629ddf31fed0a853a121275806170e34c926d69e53a7fcbccb 1/1 26s 9m30s NAME DATA AGE configmap/1de9443b6324e629ddf31fed0a853a121275806170e34c926d69e53a7fcbccb 3 9m30s Delete the job: USD oc delete job <job_name> -n openshift-marketplace This ensures pods that try to pull the inaccessible image are not recreated. Delete the config map: USD oc delete configmap <configmap_name> -n openshift-marketplace Reinstall the Operator using OperatorHub in the web console. Verification Check that the Operator has been reinstalled successfully: USD oc get sub,csv,installplan -n <namespace> 4.4. Configuring Operator Lifecycle Manager features The Operator Lifecycle Manager (OLM) controller is configured by an OLMConfig custom resource (CR) named cluster . Cluster administrators can modify this resource to enable or disable certain features. This document outlines the features currently supported by OLM that are configured by the OLMConfig resource. 4.4.1. Disabling copied CSVs When an Operator is installed by Operator Lifecycle Manager (OLM), a simplified copy of its cluster service version (CSV) is created in every namespace that the Operator is configured to watch. These CSVs are known as copied CSVs and communicate to users which controllers are actively reconciling resource events in a given namespace. When Operators are configured to use the AllNamespaces install mode, versus targeting a single or specified set of namespaces, a copied CSV is created in every namespace on the cluster. On especially large clusters, with namespaces and installed Operators potentially in the hundreds or thousands, copied CSVs consume an untenable amount of resources, such as OLM's memory usage, cluster etcd limits, and networking. To support these larger clusters, cluster administrators can disable copied CSVs for Operators installed with the AllNamespaces mode. Warning If you disable copied CSVs, a user's ability to discover Operators in the OperatorHub and CLI is limited to Operators installed directly in the user's namespace. If an Operator is configured to reconcile events in the user's namespace but is installed in a different namespace, the user cannot view the Operator in the OperatorHub or CLI. Operators affected by this limitation are still available and continue to reconcile events in the user's namespace. This behavior occurs for the following reasons: Copied CSVs identify the Operators available for a given namespace. Role-based access control (RBAC) scopes the user's ability to view and discover Operators in the OperatorHub and CLI. Procedure Edit the OLMConfig object named cluster and set the spec.features.disableCopiedCSVs field to true : USD oc apply -f - <<EOF apiVersion: operators.coreos.com/v1 kind: OLMConfig metadata: name: cluster spec: features: disableCopiedCSVs: true 1 EOF 1 Disabled copied CSVs for AllNamespaces install mode Operators Verification When copied CSVs are disabled, OLM captures this information in an event in the Operator's namespace: USD oc get events Example output LAST SEEN TYPE REASON OBJECT MESSAGE 85s Warning DisabledCopiedCSVs clusterserviceversion/my-csv.v1.0.0 CSV copying disabled for operators/my-csv.v1.0.0 When the spec.features.disableCopiedCSVs field is missing or set to false , OLM recreates the copied CSVs for all Operators installed with the AllNamespaces mode and deletes the previously mentioned events. Additional resources Install modes 4.5. Configuring proxy support in Operator Lifecycle Manager If a global proxy is configured on the OpenShift Container Platform cluster, Operator Lifecycle Manager (OLM) automatically configures Operators that it manages with the cluster-wide proxy. However, you can also configure installed Operators to override the global proxy or inject a custom CA certificate. Additional resources Configuring the cluster-wide proxy Configuring a custom PKI (custom CA certificate) Developing Operators that support proxy settings for Go , Ansible , and Helm 4.5.1. Overriding proxy settings of an Operator If a cluster-wide egress proxy is configured, Operators running with Operator Lifecycle Manager (OLM) inherit the cluster-wide proxy settings on their deployments. Cluster administrators can also override these proxy settings by configuring the subscription of an Operator. Important Operators must handle setting environment variables for proxy settings in the pods for any managed Operands. Prerequisites Access to an OpenShift Container Platform cluster using an account with cluster-admin permissions. Procedure Navigate in the web console to the Operators OperatorHub page. Select the Operator and click Install . On the Install Operator page, modify the Subscription object to include one or more of the following environment variables in the spec section: HTTP_PROXY HTTPS_PROXY NO_PROXY For example: Subscription object with proxy setting overrides apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: name: etcd-config-test namespace: openshift-operators spec: config: env: - name: HTTP_PROXY value: test_http - name: HTTPS_PROXY value: test_https - name: NO_PROXY value: test channel: clusterwide-alpha installPlanApproval: Automatic name: etcd source: community-operators sourceNamespace: openshift-marketplace startingCSV: etcdoperator.v0.9.4-clusterwide Note These environment variables can also be unset using an empty value to remove any previously set cluster-wide or custom proxy settings. OLM handles these environment variables as a unit; if at least one of them is set, all three are considered overridden and the cluster-wide defaults are not used for the deployments of the subscribed Operator. Click Install to make the Operator available to the selected namespaces. After the CSV for the Operator appears in the relevant namespace, you can verify that custom proxy environment variables are set in the deployment. For example, using the CLI: USD oc get deployment -n openshift-operators \ etcd-operator -o yaml \ | grep -i "PROXY" -A 2 Example output - name: HTTP_PROXY value: test_http - name: HTTPS_PROXY value: test_https - name: NO_PROXY value: test image: quay.io/coreos/etcd-operator@sha256:66a37fd61a06a43969854ee6d3e21088a98b93838e284a6086b13917f96b0d9c ... 4.5.2. Injecting a custom CA certificate When a cluster administrator adds a custom CA certificate to a cluster using a config map, the Cluster Network Operator merges the user-provided certificates and system CA certificates into a single bundle. You can inject this merged bundle into your Operator running on Operator Lifecycle Manager (OLM), which is useful if you have a man-in-the-middle HTTPS proxy. Prerequisites Access to an OpenShift Container Platform cluster using an account with cluster-admin permissions. Custom CA certificate added to the cluster using a config map. Desired Operator installed and running on OLM. Procedure Create an empty config map in the namespace where the subscription for your Operator exists and include the following label: apiVersion: v1 kind: ConfigMap metadata: name: trusted-ca 1 labels: config.openshift.io/inject-trusted-cabundle: "true" 2 1 Name of the config map. 2 Requests the Cluster Network Operator to inject the merged bundle. After creating this config map, it is immediately populated with the certificate contents of the merged bundle. Update your the Subscription object to include a spec.config section that mounts the trusted-ca config map as a volume to each container within a pod that requires a custom CA: apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: name: my-operator spec: package: etcd channel: alpha config: 1 selector: matchLabels: <labels_for_pods> 2 volumes: 3 - name: trusted-ca configMap: name: trusted-ca items: - key: ca-bundle.crt 4 path: tls-ca-bundle.pem 5 volumeMounts: 6 - name: trusted-ca mountPath: /etc/pki/ca-trust/extracted/pem readOnly: true 1 Add a config section if it does not exist. 2 Specify labels to match pods that are owned by the Operator. 3 Create a trusted-ca volume. 4 ca-bundle.crt is required as the config map key. 5 tls-ca-bundle.pem is required as the config map path. 6 Create a trusted-ca volume mount. Note Deployments of an Operator can fail to validate the authority and display a x509 certificate signed by unknown authority error. This error can occur even after injecting a custom CA when using the subscription of an Operator. In this case, you can set the mountPath as /etc/ssl/certs for trusted-ca by using the subscription of an Operator. 4.6. Viewing Operator status Understanding the state of the system in Operator Lifecycle Manager (OLM) is important for making decisions about and debugging problems with installed Operators. OLM provides insight into subscriptions and related catalog sources regarding their state and actions performed. This helps users better understand the healthiness of their Operators. 4.6.1. Operator subscription condition types Subscriptions can report the following condition types: Table 4.1. Subscription condition types Condition Description CatalogSourcesUnhealthy Some or all of the catalog sources to be used in resolution are unhealthy. InstallPlanMissing An install plan for a subscription is missing. InstallPlanPending An install plan for a subscription is pending installation. InstallPlanFailed An install plan for a subscription has failed. ResolutionFailed The dependency resolution for a subscription has failed. Note Default OpenShift Container Platform cluster Operators are managed by the Cluster Version Operator (CVO) and they do not have a Subscription object. Application Operators are managed by Operator Lifecycle Manager (OLM) and they have a Subscription object. Additional resources Refreshing failing subscriptions 4.6.2. Viewing Operator subscription status by using the CLI You can view Operator subscription status by using the CLI. Prerequisites You have access to the cluster as a user with the cluster-admin role.

Viewing Operator catalog source status by using the CLI You can view the status of an Operator catalog source by using the CLI. Prerequisites You have access to the cluster as a user with the cluster-admin role. You have installed the OpenShift CLI ( oc ). Procedure List the catalog sources in a namespace. For example, you can check the openshift-marketplace namespace, which is used for cluster-wide catalog sources: USD oc get catalogsources -n openshift-marketplace Example output NAME DISPLAY TYPE PUBLISHER AGE certified-operators Certified Operators grpc Red Hat 55m community-operators Community Operators grpc Red Hat 55m example-catalog Example Catalog grpc Example Org 2m25s redhat-marketplace Red Hat Marketplace grpc Red Hat 55m redhat-operators Red Hat Operators grpc Red Hat 55m Use the oc describe command to get more details and status about a catalog source: USD oc describe catalogsource example-catalog -n openshift-marketplace Example output Name: example-catalog Namespace: openshift-marketplace Labels: <none> Annotations: operatorframework.io/managed-by: marketplace-operator target.workload.openshift.io/management: {"effect": "PreferredDuringScheduling"} API Version: operators.coreos.com/v1alpha1 Kind: CatalogSource # ...

Managing Operator conditions As a cluster administrator, you can manage Operator conditions by using Operator Lifecycle Manager (OLM). 4.7.1. Overriding Operator conditions As a cluster administrator, you might want to ignore a supported Operator condition reported by an Operator. When present, Operator conditions in the Spec.Overrides array override the conditions in the Spec.Conditions array, allowing cluster administrators to deal with situations where an Operator is incorrectly reporting a state to Operator Lifecycle Manager (OLM). Note By default, the Spec.Overrides array is not present in an OperatorCondition object until it is added by a cluster administrator. The Spec.Conditions array is also not present until it is either added by a user or as a result of custom Operator logic. For example, consider a known version of an Operator that always communicates that it is not upgradeable. In this instance, you might want to upgrade the Operator despite the Operator communicating that it is not upgradeable. This could be accomplished by overriding the Operator condition by adding the condition type and status to the Spec.Overrides array in the OperatorCondition object. Prerequisites An Operator with an OperatorCondition object, installed using OLM. Procedure Edit the OperatorCondition object for the Operator: USD oc edit operatorcondition <name> Add a Spec.Overrides array to the object: Example Operator condition override apiVersion: operators.coreos.com/v1 kind: OperatorCondition metadata: name: my-operator namespace: operators spec: overrides: - type: Upgradeable 1 status: "True" reason: "upgradeIsSafe" message: "This is a known issue with the Operator where it always reports that it cannot be upgraded." conditions: - type: Upgradeable status: "False" reason: "migration" message: "The operator is performing a migration." lastTransitionTime: "2020-08-24T23:15:55Z" 1 Allows the cluster administrator to change the upgrade readiness to True . 4.7.2. Updating your Operator to use Operator conditions Operator Lifecycle Manager (OLM) automatically creates an OperatorCondition resource for each ClusterServiceVersion resource that it reconciles. All service accounts in the CSV are granted the RBAC to interact with the OperatorCondition owned by the Operator. An Operator author can develop their Operator to use the operator-lib library such that, after the Operator has been deployed by OLM, it can set its own conditions. For more resources about setting Operator conditions as an Operator author, see the Enabling Operator conditions page. 4.7.2.1. Setting defaults In an effort to remain backwards compatible, OLM treats the absence of an OperatorCondition resource as opting out of the condition. Therefore, an Operator that opts in to using Operator conditions should set default conditions before the ready probe for the pod is set to true . This provides the Operator with a grace period to update the condition to the correct state. 4.7.3. Additional resources Operator conditions 4.8. Allowing non-cluster administrators to install Operators Cluster administrators can use Operator groups to allow regular users to install Operators. Additional resources Operator groups 4.8.1. Understanding Operator installation policy Operators can require wide privileges to run, and the required privileges can change between versions. Operator Lifecycle Manager (OLM) runs with cluster-admin privileges. By default, Operator authors can specify any set of permissions in the cluster service version (CSV), and OLM consequently grants it to the Operator. To ensure that an Operator cannot achieve cluster-scoped privileges and that users cannot escalate privileges using OLM, Cluster administrators can manually audit Operators before they are added to the cluster. Cluster administrators are also provided tools for determining and constraining which actions are allowed during an Operator installation or upgrade using service accounts. Cluster administrators can associate an Operator group with a service account that has a set of privileges granted to it. The service account sets policy on Operators to ensure they only run within predetermined boundaries by using role-based access control (RBAC) rules. As a result, the Operator is unable to do anything that is not explicitly permitted by those rules. By employing Operator groups, users with enough privileges can install Operators with a limited scope. As a result, more of the Operator Framework tools can safely be made available to more users, providing a richer experience for building applications with Operators. Note Role-based access control (RBAC) for Subscription objects is automatically granted to every user with the edit or admin role in a namespace. However, RBAC does not exist on OperatorGroup objects; this absence is what prevents regular users from installing Operators. Preinstalling Operator groups is effectively what gives installation privileges. Keep the following points in mind when associating an Operator group with a service account: The APIService and CustomResourceDefinition resources are always created by OLM using the cluster-admin role. A service account associated with an Operator group should never be granted privileges to write these resources. Any Operator tied to this Operator group is now confined to the permissions granted to the specified service account. If the Operator asks for permissions that are outside the scope of the service account, the install fails with appropriate errors so the cluster administrator can troubleshoot and resolve the issue. 4.8.1.1. Installation scenarios When determining whether an Operator can be installed or upgraded on a cluster, Operator Lifecycle Manager (OLM) considers the following scenarios: A cluster administrator creates a new Operator group and specifies a service account. All Operator(s) associated with this Operator group are installed and run against the privileges granted to the service account. A cluster administrator creates a new Operator group and does not specify any service account. OpenShift Container Platform maintains backward compatibility, so the default behavior remains and Operator installs and upgrades are permitted. For existing Operator groups that do not specify a service account, the default behavior remains and Operator installs and upgrades are permitted. A cluster administrator updates an existing Operator group and specifies a service account. OLM allows the existing Operator to continue to run with their current privileges. When such an existing Operator is going through an upgrade, it is reinstalled and run against the privileges granted to the service account like any new Operator. A service account specified by an Operator group changes by adding or removing permissions, or the existing service account is swapped with a new one. When existing Operators go through an upgrade, it is reinstalled and run against the privileges granted to the updated service account like any new Operator. A cluster administrator removes the service account from an Operator group. The default behavior remains and Operator installs and upgrades are permitted. 4.8.1.2. Installation workflow When an Operator group is tied to a service account and an Operator is installed or upgraded, Operator Lifecycle Manager (OLM) uses the following workflow: The given Subscription object is picked up by OLM. OLM fetches the Operator group tied to this subscription. OLM determines that the Operator group has a service account specified. OLM creates a client scoped to the service account and uses the scoped client to install the Operator. This ensures that any permission requested by the Operator is always confined to that of the service account in the Operator group. OLM creates a new service account with the set of permissions specified in the CSV and assigns it to the Operator. The Operator runs as the assigned service account. 4.8.2. Scoping Operator installations To provide scoping rules to Operator installations and upgrades on Operator Lifecycle Manager (OLM), associate a service account with an Operator group. Using this example, a cluster administrator can confine a set of Operators to a designated namespace. Procedure Create a new namespace: USD cat <<EOF | oc create -f - apiVersion: v1 kind: Namespace metadata: name: scoped EOF Allocate permissions that you want the Operator(s) to be confined to. This involves creating a new service account, relevant role(s), and role binding(s). USD cat <<EOF | oc create -f - apiVersion: v1 kind: ServiceAccount metadata: name: scoped namespace: scoped EOF The following example grants the service account permissions to do anything in the designated namespace for simplicity. In a production environment, you should create a more fine-grained set of permissions: USD cat <<EOF | oc create -f - apiVersion: rbac.authorization.k8s.io/v1 kind: Role metadata: name: scoped namespace: scoped rules: - apiGroups: ["*"] resources: ["*"] verbs: ["*"] --- apiVersion: rbac.authorization.k8s.io/v1 kind: RoleBinding metadata: name: scoped-bindings namespace: scoped roleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: scoped subjects: - kind: ServiceAccount name: scoped namespace: scoped EOF Create an OperatorGroup object in the designated namespace. This Operator group targets the designated namespace to ensure that its tenancy is confined to it. In addition, Operator groups allow a user to specify a service account. Specify the service account created in the step: USD cat <<EOF | oc create -f - apiVersion: operators.coreos.com/v1 kind: OperatorGroup metadata: name: scoped namespace: scoped spec: serviceAccountName: scoped targetNamespaces: - scoped EOF Any Operator installed in the designated namespace is tied to this Operator group and therefore to the service account specified. Warning Operator Lifecycle Manager (OLM) creates the following cluster roles for each Operator group: <operatorgroup_name>-admin <operatorgroup_name>-edit <operatorgroup_name>-view When you manually create an Operator group, you must specify a unique name that does not conflict with the existing cluster roles or other Operator groups on the cluster. Create a Subscription object in the designated namespace to install an Operator: USD cat <<EOF | oc create -f - apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: name: etcd namespace: scoped spec: channel: singlenamespace-alpha name: etcd source: <catalog_source_name> 1 sourceNamespace: <catalog_source_namespace> 2 EOF 1 Specify a catalog source that already exists in the designated namespace or one that is in the global catalog namespace. 2 Specify a namespace where the catalog source was created. Any Operator tied to this Operator group is confined to the permissions granted to the specified service account. If the Operator requests permissions that are outside the scope of the service account, the installation fails with relevant errors. 4.8.2.1. Fine-grained permissions Operator Lifecycle Manager (OLM) uses the service account specified in an Operator group to create or update the following resources related to the Operator being installed: ClusterServiceVersion Subscription Secret ServiceAccount Service ClusterRole and ClusterRoleBinding Role and RoleBinding To confine Operators to a designated namespace, cluster administrators can start by granting the following permissions to the service account: Note The following role is a generic example and additional rules might be required based on the specific Operator. kind: Role rules: - apiGroups: ["operators.coreos.com"] resources: ["subscriptions", "clusterserviceversions"] verbs: ["get", "create", "update", "patch"] - apiGroups: [""] resources: ["services", "serviceaccounts"] verbs: ["get", "create", "update", "patch"] - apiGroups: ["rbac.authorization.k8s.io"] resources: ["roles", "rolebindings"] verbs: ["get", "create", "update", "patch"] - apiGroups: ["apps"] 1 resources: ["deployments"] verbs: ["list", "watch", "get", "create", "update", "patch", "delete"] - apiGroups: [""] 2 resources: ["pods"] verbs: ["list", "watch", "get", "create", "update", "patch", "delete"] 1 2 Add permissions to create other resources, such as deployments and pods shown here. In addition, if any Operator specifies a pull secret, the following permissions must also be added: kind: ClusterRole 1 rules: - apiGroups: [""] resources: ["secrets"] verbs: ["get"] --- kind: Role rules: - apiGroups: [""] resources: ["secrets"] verbs: ["create", "update", "patch"] 1 Required to get the secret from the OLM namespace. 4.8.3. Operator catalog access control When an Operator catalog is created in the global catalog namespace openshift-marketplace , the catalog's Operators are made available cluster-wide to all namespaces. A catalog created in other namespaces only makes its Operators available in that same namespace of the catalog. On clusters where non-cluster administrator users have been delegated Operator installation privileges, cluster administrators might want to further control or restrict the set of Operators those users are allowed to install. This can be achieved with the following actions: Disable all of the default global catalogs. Enable custom, curated catalogs in the same namespace where the relevant Operator groups have been preinstalled. Additional resources Disabling the default OperatorHub sources Adding a catalog source to a cluster 4.8.4. Troubleshooting permission failures If an Operator installation fails due to lack of permissions, identify the errors using the following procedure. Procedure Review the Subscription object. Its status has an object reference installPlanRef that points to the InstallPlan object that attempted to create the necessary [Cluster]Role[Binding] object(s) for the Operator: apiVersion: operators.coreos.com/v1 kind: Subscription metadata: name: etcd namespace: scoped status: installPlanRef: apiVersion: operators.coreos.com/v1 kind: InstallPlan name: install-4plp8 namespace: scoped resourceVersion: "117359" uid: 2c1df80e-afea-11e9-bce3-5254009c9c23 Check the status of the InstallPlan object for any errors: apiVersion: operators.coreos.com/v1 kind: InstallPlan status: conditions: - lastTransitionTime: "2019-07-26T21:13:10Z" lastUpdateTime: "2019-07-26T21:13:10Z" message: 'error creating clusterrole etcdoperator.v0.9.4-clusterwide-dsfx4: clusterroles.rbac.authorization.k8s.io is forbidden: User "system:serviceaccount:scoped:scoped" cannot create resource "clusterroles" in API group "rbac.authorization.k8s.io" at the cluster scope' reason: InstallComponentFailed status: "False" type: Installed phase: Failed The error message tells you: The type of resource it failed to create, including the API group of the resource. In this case, it was clusterroles in the rbac.authorization.k8s.io group. The name of the resource. The type of error: is forbidden tells you that the user does not have enough permission to do the operation. The name of the user who attempted to create or update the resource. In this case, it refers to the service account specified in the Operator group. The scope of the operation: cluster scope or not. The user can add the missing permission to the service account and then iterate. Note Operator Lifecycle Manager (OLM) does not currently provide the complete list of errors on the first try. 4.9. Managing custom catalogs Cluster administrators and Operator catalog maintainers can create and manage custom catalogs packaged using the bundle format on Operator Lifecycle Manager (OLM) in OpenShift Container Platform. Important Kubernetes periodically deprecates certain APIs that are removed in subsequent releases. As a result, Operators are unable to use removed APIs starting with the version of OpenShift Container Platform that uses the Kubernetes version that removed the API. If your cluster is using custom catalogs, see Controlling Operator compatibility with OpenShift Container Platform versions for more details about how Operator authors can update their projects to help avoid workload issues and prevent incompatible upgrades. Additional resources Red Hat-provided Operator catalogs 4.9.1. Prerequisites Install the opm CLI . 4.9.2. File-based catalogs File-based catalogs are the latest iteration of the catalog format in Operator Lifecycle Manager (OLM). It is a plain text-based (JSON or YAML) and declarative config evolution of the earlier SQLite database format, and it is fully backwards compatible. Important As of OpenShift Container Platform 4.11, the default Red Hat-provided Operator catalog releases in the file-based catalog format. The default Red Hat-provided Operator catalogs for OpenShift Container Platform 4.6 through 4.10 released in the deprecated SQLite database format. The opm subcommands, flags, and functionality related to the SQLite database format are also deprecated and will be removed in a future release. The features are still supported and must be used for catalogs that use the deprecated SQLite database format. Many of the opm subcommands and flags for working with the SQLite database format, such as opm index prune , do not work with the file-based catalog format. For more information about working with file-based catalogs, see Operator Framework packaging format and Mirroring images for a disconnected installation using the oc-mirror plugin . 4.9.2.1. Creating a file-based catalog image You can use the opm CLI to create a catalog image that uses the plain text file-based catalog format (JSON or YAML), which replaces the deprecated SQLite database format. Prerequisites opm podman version 1.9.3+ A bundle image built and pushed to a registry that supports Docker v2-2 Procedure Initialize the catalog: Create a directory for the catalog by running the following command: USD mkdir <catalog_dir> Generate a Dockerfile that can build a catalog image by running the opm generate dockerfile command: USD opm generate dockerfile <catalog_dir> \ -i registry.redhat.io/openshift4/ose-operator-registry:v4.11 1 1 Specify the official Red Hat base image by using the -i flag, otherwise the Dockerfile uses the default upstream image. The Dockerfile must be in the same parent directory as the catalog directory that you created in the step: Example directory structure . 1 ├── <catalog_dir> 2 └── <catalog_dir>.Dockerfile 3 1 Parent directory 2 Catalog directory 3 Dockerfile generated by the opm generate dockerfile command Populate the catalog with the package definition for your Operator by running the opm init command: USD opm init <operator_name> \ 1 --default-channel=preview \ 2 --description=./README.md \ 3 --icon=./operator-icon.svg \ 4 --output yaml \ 5 > <catalog_dir>/index.yaml 6 1 Operator, or package, name 2 Channel that subscriptions default to if unspecified 3 Path to the Operator's README.md or other documentation 4 Path to the Operator's icon 5 Output format: JSON or YAML 6 Path for creating the catalog configuration file This command generates an olm.package declarative config blob in the specified catalog configuration file. Add a bundle to the catalog by running the opm render command: USD opm render <registry>/<namespace>/<bundle_image_name>:<tag> \ 1 --output=yaml \ >> <catalog_dir>/index.yaml 2 1 Pull spec for the bundle image 2 Path to the catalog configuration file Note Channels must contain at least one bundle. Add a channel entry for the bundle. For example, modify the following example to your specifications, and add it to your <catalog_dir>/index.yaml file: Example channel entry --- schema: olm.channel package: <operator_name> name: preview entries: - name: <operator_name>.v0.1.0 1 1 Ensure that you include the period ( . ) after <operator_name> but before the v in the version. Otherwise, the entry fails to pass the opm validate command. Validate the file-based catalog: Run the opm validate command against the catalog directory: USD opm validate <catalog_dir> Check that the error code is 0 : USD echo USD? Example output 0 Build the catalog image by running the podman build command: USD podman build . \ -f <catalog_dir>.Dockerfile \ -t <registry>/<namespace>/<catalog_image_name>:<tag> Push the catalog image to a registry: If required, authenticate with your target registry by running the podman login command: USD podman login <registry> Push the catalog image by running the podman push command: USD podman push <registry>/<namespace>/<catalog_image_name>:<tag> Additional resources opm CLI reference 4.9.2.2. Updating or filtering a file-based catalog image You can use the opm CLI to update or filter (also known as prune) a catalog image that uses the file-based catalog format. By extracting and modifying the contents of an existing catalog image, you can update, add, or remove one or more Operator package entries from the catalog. You can then rebuild the image as an updated version of the catalog. Note Alternatively, if you already have a catalog image on a mirror registry, you can use the oc-mirror CLI plugin to automatically prune any removed images from an updated source version of that catalog image while mirroring it to the target registry. For more information about the oc-mirror plugin and this use case, see the "Keeping your mirror registry content updated" section, and specifically the "Pruning images" subsection, of "Mirroring images for a disconnected installation using the oc-mirror plugin". Prerequisites opm CLI. podman version 1.9.3+. A file-based catalog image. A catalog directory structure recently initialized on your workstation related to this catalog. If you do not have an initialized catalog directory, create the directory and generate the Dockerfile. For more information, see the "Initialize the catalog" step from the "Creating a file-based catalog image" procedure. Procedure Extract the contents of the catalog image in YAML format to an index.yaml file in your catalog directory: USD opm render <registry>/<namespace>/<catalog_image_name>:<tag> \ -o yaml > <catalog_dir>/index.yaml Note Alternatively, you can use the -o json flag to output in JSON format. Modify the contents of the resulting index.yaml file to your specifications by updating, adding, or removing one or more Operator package entries. Important After a bundle has been published in a catalog, assume that one of your users has installed it. Ensure that all previously published bundles in a catalog have an update path to the current or newer channel head to avoid stranding users that have that version installed. For example, if you wanted to remove an Operator package, the following example lists a set of olm.package , olm.channel , and olm.bundle blobs which must be deleted to remove the package from the catalog: Example 4.1. Example removed entries --- defaultChannel: release-2.7 icon: base64data: <base64_string> mediatype: image/svg+xml name: example-operator schema: olm.package --- entries: - name: example-operator.v2.7.0 skipRange: '>=2.6.0 <2.7.0' - name: example-operator.v2.7.1 replaces: example-operator.v2.7.0 skipRange: '>=2.6.0 <2.7.1' - name: example-operator.v2.7.2 replaces: example-operator.v2.7.1 skipRange: '>=2.6.0 <2.7.2' - name: example-operator.v2.7.3 replaces: example-operator.v2.7.2 skipRange: '>=2.6.0 <2.7.3' - name: example-operator.v2.7.4 replaces: example-operator.v2.7.3 skipRange: '>=2.6.0 <2.7.4' name: release-2.7 package: example-operator schema: olm.channel --- image: example.com/example-inc/example-operator-bundle@sha256:<digest> name: example-operator.v2.7.0 package: example-operator properties: - type: olm.gvk value: group: example-group.example.io kind: MyObject version: v1alpha1 - type: olm.gvk value: group: example-group.example.io kind: MyOtherObject version: v1beta1 - type: olm.package value: packageName: example-operator version: 2.7.0 - type: olm.bundle.object value: data: <base64_string> - type: olm.bundle.object value: data: <base64_string> relatedImages: - image: example.com/example-inc/example-related-image@sha256:<digest> name: example-related-image schema: olm.bundle --- Save your changes to the index.yaml file.

SQLite-based catalogs Important The SQLite database format for Operator catalogs is a deprecated feature. Deprecated functionality is still included in OpenShift Container Platform and continues to be supported; however, it will be removed in a future release of this product and is not recommended for new deployments. For the most recent list of major functionality that has been deprecated or removed within OpenShift Container Platform, refer to the Deprecated and removed features section of the OpenShift Container Platform release notes. 4.9.3.1. Creating a SQLite-based index image You can create an index image based on the SQLite database format by using the opm CLI. Prerequisites opm podman version 1.9.3+ A bundle image built and pushed to a registry that supports Docker v2-2 Procedure Start a new index: USD opm index add \ --bundles <registry>/<namespace>/<bundle_image_name>:<tag> \ 1 --tag <registry>/<namespace>/<index_image_name>:<tag> \ 2 [--binary-image <registry_base_image>] 3 1 Comma-separated list of bundle images to add to the index. 2 The image tag that you want the index image to have. 3 Optional: An alternative registry base image to use for serving the catalog. Push the index image to a registry. If required, authenticate with your target registry: USD podman login <registry> Push the index image: USD podman push <registry>/<namespace>/<index_image_name>:<tag> 4.9.3.2. Updating a SQLite-based index image After configuring OperatorHub to use a catalog source that references a custom index image, cluster administrators can keep the available Operators on their cluster up to date by adding bundle images to the index image. You can update an existing index image using the opm index add command. Prerequisites opm podman version 1.9.3+ An index image built and pushed to a registry. An existing catalog source referencing the index image. Procedure Update the existing index by adding bundle images: USD opm index add \ --bundles <registry>/<namespace>/<new_bundle_image>@sha256:<digest> \ 1 --from-index <registry>/<namespace>/<existing_index_image>:<existing_tag> \ 2 --tag <registry>/<namespace>/<existing_index_image>:<updated_tag> \ 3 --pull-tool podman 4 1 The --bundles flag specifies a comma-separated list of additional bundle images to add to the index. 2 The --from-index flag specifies the previously pushed index. 3 The --tag flag specifies the image tag to apply to the updated index image. 4 The --pull-tool flag specifies the tool used to pull container images. where: <registry> Specifies the hostname of the registry, such as quay.io or mirror.example.com . <namespace> Specifies the namespace of the registry, such as ocs-dev or abc . <new_bundle_image> Specifies the new bundle image to add to the registry, such as ocs-operator . <digest> Specifies the SHA image ID, or digest, of the bundle image, such as c7f11097a628f092d8bad148406aa0e0951094a03445fd4bc0775431ef683a41 . <existing_index_image> Specifies the previously pushed image, such as abc-redhat-operator-index . <existing_tag> Specifies a previously pushed image tag, such as 4.11 . <updated_tag> Specifies the image tag to apply to the updated index image, such as 4.11.1 .

Filtering a SQLite-based index image An index image, based on the Operator bundle format, is a containerized snapshot of an Operator catalog. You can filter, or prune , an index of all but a specified list of packages, which creates a copy of the source index containing only the Operators that you want. Prerequisites podman version 1.9.3+ grpcurl (third-party command-line tool) opm Access to a registry that supports Docker v2-2 Procedure Authenticate with your target registry: USD podman login <target_registry> Determine the list of packages you want to include in your pruned index. Run the source index image that you want to prune in a container. For example: USD podman run -p50051:50051 \ -it registry.redhat.io/redhat/redhat-operator-index:v4.11 Example output Trying to pull registry.redhat.io/redhat/redhat-operator-index:v4.11... Getting image source signatures Copying blob ae8a0c23f5b1 done ... INFO[0000] serving registry database=/database/index.db port=50051 In a separate terminal session, use the grpcurl command to get a list of the packages provided by the index: USD grpcurl -plaintext localhost:50051 api.Registry/ListPackages > packages.out Inspect the packages.out file and identify which package names from this list you want to keep in your pruned index. For example: Example snippets of packages list ... { "name": "advanced-cluster-management" } ... { "name": "jaeger-product" } ... { { "name": "quay-operator" } ... In the terminal session where you executed the podman run command, press Ctrl and C to stop the container process. Run the following command to prune the source index of all but the specified packages: USD opm index prune \ -f registry.redhat.io/redhat/redhat-operator-index:v4.11 \ 1 -p advanced-cluster-management,jaeger-product,quay-operator \ 2 [-i registry.redhat.io/openshift4/ose-operator-registry:v4.9] \ 3 -t <target_registry>:<port>/<namespace>/redhat-operator-index:v4.11 4 1 Index to prune. 2 Comma-separated list of packages to keep. 3 Required only for IBM Power and IBM Z images: Operator Registry base image with the tag that matches the target OpenShift Container Platform cluster major and minor version. 4 Custom tag for new index image being built. Run the following command to push the new index image to your target registry: USD podman push <target_registry>:<port>/<namespace>/redhat-operator-index:v4.11 where <namespace> is any existing namespace on the registry. 4.9.4. Adding a catalog source to a cluster Adding a catalog source to an OpenShift Container Platform cluster enables the discovery and installation of Operators for users. Cluster administrators can create a CatalogSource object that references an index image. OperatorHub uses catalog sources to populate the user interface. Tip Alternatively, you can use the web console to manage catalog sources. From the Administration Cluster Settings Configuration OperatorHub page, click the Sources tab, where you can create, update, delete, disable, and enable individual sources. Prerequisites An index image built and pushed to a registry. Procedure Create a CatalogSource object that references your index image. Modify the following to your specifications and save it as a catalogSource.yaml file: apiVersion: operators.coreos.com/v1alpha1 kind: CatalogSource metadata: name: my-operator-catalog namespace: openshift-marketplace 1 annotations: olm.catalogImageTemplate: 2 "<registry>/<namespace>/<index_image_name>:v{kube_major_version}.{kube_minor_version}.{kube_patch_version}" spec: sourceType: grpc image: <registry>/<namespace>/<index_image_name>:<tag> 3 displayName: My Operator Catalog publisher: <publisher_name> 4 updateStrategy: registryPoll: 5 interval: 30m 1 If you want the catalog source to be available globally to users in all namespaces, specify the openshift-marketplace namespace. Otherwise, you can specify a different namespace for the catalog to be scoped and available only for that namespace. 2 Optional: Set the olm.catalogImageTemplate annotation to your index image name and use one or more of the Kubernetes cluster version variables as shown when constructing the template for the image tag. 3 Specify your index image. If you specify a tag after the image name, for example :v4.11 , the catalog source pod uses an image pull policy of Always , meaning the pod always pulls the image prior to starting the container. If you specify a digest, for example @sha256:<id> , the image pull policy is IfNotPresent , meaning the pod pulls the image only if it does not already exist on the node. 4 Specify your name or an organization name publishing the catalog. 5 Catalog sources can automatically check for new versions to keep up to date. Use the file to create the CatalogSource object: USD oc apply -f catalogSource.yaml Verify the following resources are created successfully. Check the pods: USD oc get pods -n openshift-marketplace Example output NAME READY STATUS RESTARTS AGE my-operator-catalog-6njx6 1/1 Running 0 28s marketplace-operator-d9f549946-96sgr 1/1 Running 0 26h Check the catalog source: USD oc get catalogsource -n openshift-marketplace Example output NAME DISPLAY TYPE PUBLISHER AGE my-operator-catalog My Operator Catalog grpc 5s Check the package manifest: USD oc get packagemanifest -n openshift-marketplace Example output NAME CATALOG AGE jaeger-product My Operator Catalog 93s You can now install the Operators from the OperatorHub page on your OpenShift Container Platform web console. Additional resources Operator Lifecycle Manager concepts and resources Catalog source Accessing images for Operators from private registries Image pull policy 4.9.5. Accessing images for Operators from private registries If certain images relevant to Operators managed by Operator Lifecycle Manager (OLM) are hosted in an authenticated container image registry, also known as a private registry, OLM and OperatorHub are unable to pull the images by default. To enable access, you can create a pull secret that contains the authentication credentials for the registry. By referencing one or more pull secrets in a catalog source, OLM can handle placing the secrets in the Operator and catalog namespace to allow installation. Other images required by an Operator or its Operands might require access to private registries as well. OLM does not handle placing the secrets in target tenant namespaces for this scenario, but authentication credentials can be added to the global cluster pull secret or individual namespace service accounts to enable the required access. The following types of images should be considered when determining whether Operators managed by OLM have appropriate pull access: Index images A CatalogSource object can reference an index image, which use the Operator bundle format and are catalog sources packaged as container images hosted in images registries. If an index image is hosted in a private registry, a secret can be used to enable pull access. Bundle images Operator bundle images are metadata and manifests packaged as container images that represent a unique version of an Operator. If any bundle images referenced in a catalog source are hosted in one or more private registries, a secret can be used to enable pull access. Operator and Operand images If an Operator installed from a catalog source uses a private image, either for the Operator image itself or one of the Operand images it watches, the Operator will fail to install because the deployment will not have access to the required registry authentication. Referencing secrets in a catalog source does not enable OLM to place the secrets in target tenant namespaces in which Operands are installed. Instead, the authentication details can be added to the global cluster pull secret in the openshift-config namespace, which provides access to all namespaces on the cluster. Alternatively, if providing access to the entire cluster is not permissible, the pull secret can be added to the default service accounts of the target tenant namespaces. Prerequisites At least one of the following hosted in a private registry: An index image or catalog image. An Operator bundle image. An Operator or Operand image. Procedure Create a secret for each required private registry. Log in to the private registry to create or update your registry credentials file: USD podman login <registry>:<port> Note The file path of your registry credentials can be different depending on the container tool used to log in to the registry. For the podman CLI, the default location is USD{XDG_RUNTIME_DIR}/containers/auth.json . For the docker CLI, the default location is /root/.docker/config.json . It is recommended to include credentials for only one registry per secret, and manage credentials for multiple registries in separate secrets. Multiple secrets can be included in a CatalogSource object in later steps, and OpenShift Container Platform will merge the secrets into a single virtual credentials file for use during an image pull. A registry credentials file can, by default, store details for more than one registry or for multiple repositories in one registry. Verify the current contents of your file. For example: File storing credentials for multiple registries { "auths": { "registry.redhat.io": { "auth": "FrNHNydQXdzclNqdg==" }, "quay.io": { "auth": "fegdsRib21iMQ==" }, "https://quay.io/my-namespace/my-user/my-image": { "auth": "eWfjwsDdfsa221==" }, "https://quay.io/my-namespace/my-user": { "auth": "feFweDdscw34rR==" }, "https://quay.io/my-namespace": { "auth": "frwEews4fescyq==" } } } Because this file is used to create secrets in later steps, ensure that you are storing details for only one registry per file. This can be accomplished by using either of the following methods: Use the podman logout <registry> command to remove credentials for additional registries until only the one registry you want remains. Edit your registry credentials file and separate the registry details to be stored in multiple files. For example: File storing credentials for one registry { "auths": { "registry.redhat.io": { "auth": "FrNHNydQXdzclNqdg==" } } } File storing credentials for another registry { "auths": { "quay.io": { "auth": "Xd2lhdsbnRib21iMQ==" } } } Create a secret in the openshift-marketplace namespace that contains the authentication credentials for a private registry: USD oc create secret generic <secret_name> \ -n openshift-marketplace \ --from-file=.dockerconfigjson=<path/to/registry/credentials> \ --type=kubernetes.io/dockerconfigjson Repeat this step to create additional secrets for any other required private registries, updating the --from-file flag to specify another registry credentials file path. Create or update an existing CatalogSource object to reference one or more secrets: apiVersion: operators.coreos.com/v1alpha1 kind: CatalogSource metadata: name: my-operator-catalog namespace: openshift-marketplace spec: sourceType: grpc secrets: 1 - "<secret_name_1>" - "<secret_name_2>" image: <registry>:<port>/<namespace>/<image>:<tag> displayName: My Operator Catalog publisher: <publisher_name> updateStrategy: registryPoll: interval: 30m 1 Add a spec.secrets section and specify any required secrets. If any Operator or Operand images that are referenced by a subscribed Operator require access to a private registry, you can either provide access to all namespaces in the cluster, or individual target tenant namespaces. To provide access to all namespaces in the cluster, add authentication details to the global cluster pull secret in the openshift-config namespace. Warning Cluster resources must adjust to the new global pull secret, which can temporarily limit the usability of the cluster. Extract the .dockerconfigjson file from the global pull secret: USD oc extract secret/pull-secret -n openshift-config --confirm Update the .dockerconfigjson file with your authentication credentials for the required private registry or registries and save it as a new file: USD cat .dockerconfigjson | \ jq --compact-output '.auths["<registry>:<port>/<namespace>/"] |= . + {"auth":"<token>"}' \ 1 > new_dockerconfigjson 1 Replace <registry>:<port>/<namespace> with the private registry details and <token> with your authentication credentials. Update the global pull secret with the new file: USD oc set data secret/pull-secret -n openshift-config \ --from-file=.dockerconfigjson=new_dockerconfigjson To update an individual namespace, add a pull secret to the service account for the Operator that requires access in the target tenant namespace. Recreate the secret that you created for the openshift-marketplace in the tenant namespace: USD oc create secret generic <secret_name> \ -n <tenant_namespace> \ --from-file=.dockerconfigjson=<path/to/registry/credentials> \ --type=kubernetes.io/dockerconfigjson Verify the name of the service account for the Operator by searching the tenant namespace: USD oc get sa -n <tenant_namespace> 1 1 If the Operator was installed in an individual namespace, search that namespace. If the Operator was installed for all namespaces, search the openshift-operators namespace. Example output NAME SECRETS AGE builder 2 6m1s default 2 6m1s deployer 2 6m1s etcd-operator 2 5m18s 1 1 Service account for an installed etcd Operator. Link the secret to the service account for the Operator: USD oc secrets link <operator_sa> \ -n <tenant_namespace> \ <secret_name> \ --for=pull Additional resources See What is a secret? for more information on the types of secrets, including those used for registry credentials. See Updating the global cluster pull secret for more details on the impact of changing this secret. See Allowing pods to reference images from other secured registries for more details on linking pull secrets to service accounts per namespace. 4.9.6. Disabling the default OperatorHub sources Operator catalogs that source content provided by Red Hat and community projects are configured for OperatorHub by default during an OpenShift Container Platform installation. As a cluster administrator, you can disable the set of default catalogs. Procedure Disable the sources for the default catalogs by adding disableAllDefaultSources: true to the OperatorHub object: USD oc patch OperatorHub cluster --type json \ -p '[{"op": "add", "path": "/spec/disableAllDefaultSources", "value": true}]' Tip Alternatively, you can use the web console to manage catalog sources. From the Administration Cluster Settings Configuration OperatorHub page, click the Sources tab, where you can create, update, delete, disable, and enable individual sources. 4.9.7. Removing custom catalogs As a cluster administrator, you can remove custom Operator catalogs that have been previously added to your cluster by deleting the related catalog source. Procedure In the Administrator perspective of the web console, navigate to Administration Cluster Settings . Click the Configuration tab, and then click OperatorHub . Click the Sources tab. Select the Options menu for the catalog that you want to remove, and then click Delete CatalogSource . 4.10. Using Operator Lifecycle Manager on restricted networks For OpenShift Container Platform clusters that are installed on restricted networks, also known as disconnected clusters , Operator Lifecycle Manager (OLM) by default cannot access the Red Hat-provided OperatorHub sources hosted on remote registries because those remote sources require full internet connectivity. However, as a cluster administrator you can still enable your cluster to use OLM in a restricted network if you have a workstation that has full internet access. The workstation, which requires full internet access to pull the remote OperatorHub content, is used to prepare local mirrors of the remote sources, and push the content to a mirror registry. The mirror registry can be located on a bastion host, which requires connectivity to both your workstation and the disconnected cluster, or a completely disconnected, or airgapped , host, which requires removable media to physically move the mirrored content to the disconnected environment. This guide describes the following process that is required to enable OLM in restricted networks: Disable the default remote OperatorHub sources for OLM. Use a workstation with full internet access to create and push local mirrors of the OperatorHub content to a mirror registry. Configure OLM to install and manage Operators from local sources on the mirror registry instead of the default remote sources. After enabling OLM in a restricted network, you can continue to use your unrestricted workstation to keep your local OperatorHub sources updated as newer versions of Operators are released. Important While OLM can manage Operators from local sources, the ability for a given Operator to run successfully in a restricted network still depends on the Operator itself meeting the following criteria: List any related images, or other container images that the Operator might require to perform their functions, in the relatedImages parameter of its ClusterServiceVersion (CSV) object. Reference all specified images by a digest (SHA) and not by a tag. You can search software on the Red Hat Ecosystem Catalog for a list of Red Hat Operators that support running in disconnected mode by filtering with the following selections: Type Containerized application Deployment method Operator Infrastructure features Disconnected Additional resources Red Hat-provided Operator catalogs Enabling your Operator for restricted network environments 4.10.1. Prerequisites Log in to your OpenShift Container Platform cluster as a user with cluster-admin privileges. Note If you are using OLM in a restricted network on IBM Z, you must have at least 12 GB allocated to the directory where you place your registry. 4.10.2. Disabling the default OperatorHub sources Operator catalogs that source content provided by Red Hat and community projects are configured for OperatorHub by default during an OpenShift Container Platform installation. In a restricted network environment, you must disable the default catalogs as a cluster administrator. You can then configure OperatorHub to use local catalog sources. Procedure Disable the sources for the default catalogs by adding disableAllDefaultSources: true to the OperatorHub object: USD oc patch OperatorHub cluster --type json \ -p '[{"op": "add", "path": "/spec/disableAllDefaultSources", "value": true}]' Tip Alternatively, you can use the web console to manage catalog sources. From the Administration Cluster Settings Configuration OperatorHub page, click the Sources tab, where you can create, update, delete, disable, and enable individual sources. 4.10.3. Mirroring an Operator catalog For instructions about mirroring Operator catalogs for use with disconnected clusters, see Installing Mirroring images for a disconnected installation . Important As of OpenShift Container Platform 4.11, the default Red Hat-provided Operator catalog releases in the file-based catalog format. The default Red Hat-provided Operator catalogs for OpenShift Container Platform 4.6 through 4.10 released in the deprecated SQLite database format. The opm subcommands, flags, and functionality related to the SQLite database format are also deprecated and will be removed in a future release. The features are still supported and must be used for catalogs that use the deprecated SQLite database format. Many of the opm subcommands and flags for working with the SQLite database format, such as opm index prune , do not work with the file-based catalog format. For more information about working with file-based catalogs, see Operator Framework packaging format , Managing custom catalogs , and Mirroring images for a disconnected installation using the oc-mirror plugin . 4.10.4. Adding a catalog source to a cluster Adding a catalog source to an OpenShift Container Platform cluster enables the discovery and installation of Operators for users. Cluster administrators can create a CatalogSource object that references an index image. OperatorHub uses catalog sources to populate the user interface. Tip Alternatively, you can use the web console to manage catalog sources. From the Administration Cluster Settings Configuration OperatorHub page, click the Sources tab, where you can create, update, delete, disable, and enable individual sources. Prerequisites An index image built and pushed to a registry. Procedure Create a CatalogSource object that references your index image. If you used the oc adm catalog mirror command to mirror your catalog to a target registry, you can use the generated catalogSource.yaml file in your manifests directory as a starting point. Modify the following to your specifications and save it as a catalogSource.yaml file: apiVersion: operators.coreos.com/v1alpha1 kind: CatalogSource metadata: name: my-operator-catalog 1 namespace: openshift-marketplace 2 spec: sourceType: grpc image: <registry>/<namespace>/redhat-operator-index:v4.11 3 displayName: My Operator Catalog publisher: <publisher_name> 4 updateStrategy: registryPoll: 5 interval: 30m 1 If you mirrored content to local files before uploading to a registry, remove any backslash ( / ) characters from the metadata.name field to avoid an "invalid resource name" error when you create the object. 2 If you want the catalog source to be available globally to users in all namespaces, specify the openshift-marketplace namespace. Otherwise, you can specify a different namespace for the catalog to be scoped and available only for that namespace. 3 Specify your index image. If you specify a tag after the image name, for example :v4.11 , the catalog source pod uses an image pull policy of Always , meaning the pod always pulls the image prior to starting the container. If you specify a digest, for example @sha256:<id> , the image pull policy is IfNotPresent , meaning the pod pulls the image only if it does not already exist on the node. 4 Specify your name or an organization name publishing the catalog. 5 Catalog sources can automatically check for new versions to keep up to date. Use the file to create the CatalogSource object: USD oc apply -f catalogSource.yaml Verify the following resources are created successfully. Check the pods: USD oc get pods -n openshift-marketplace Example output NAME READY STATUS RESTARTS AGE my-operator-catalog-6njx6 1/1 Running 0 28s marketplace-operator-d9f549946-96sgr 1/1 Running 0 26h Check the catalog source: USD oc get catalogsource -n openshift-marketplace Example output NAME DISPLAY TYPE PUBLISHER AGE my-operator-catalog My Operator Catalog grpc 5s Check the package manifest: USD oc get packagemanifest -n openshift-marketplace Example output NAME CATALOG AGE jaeger-product My Operator Catalog 93s You can now install the Operators from the OperatorHub page on your OpenShift Container Platform web console. Additional resources Accessing images for Operators from private registries Image template for custom catalog sources Image pull policy 4.11. Catalog source pod scheduling When an Operator Lifecycle Manager (OLM) catalog source of source type grpc defines a spec.image , the Catalog Operator creates a pod that serves the defined image content. By default, this pod defines the following in its spec: Only the kubernetes.io/os=linux node selector No priority class name No tolerations As an administrator, you can override these values by modifying fields in the CatalogSource object's optional spec.grpcPodConfig section. Additional resources OLM concepts and resources Catalog source 4.11.1. Overriding the node selector for catalog source pods Prequisites CatalogSource object of source type grpc with spec.image defined Procedure Edit the CatalogSource object and add or modify the spec.grpcPodConfig section to include the following: grpcPodConfig: nodeSelector: custom_label: <label> where <label> is the label for the node selector that you want catalog source pods to use for scheduling. Additional resources Placing pods on specific nodes using node selectors 4.11.2. Overriding the priority class name for catalog source pods Prequisites CatalogSource object of source type grpc with spec.image defined Procedure Edit the CatalogSource object and add or modify the spec.grpcPodConfig section to include the following: grpcPodConfig: priorityClassName: <priority_class> where <priority_class> is one of the following: One of the default priority classes provided by Kubernetes: system-cluster-critical or system-node-critical An empty set ( "" ) to assign the default priority A pre-existing and custom defined priority class Note Previously, the only pod scheduling parameter that could be overriden was priorityClassName . This was done by adding the operatorframework.io/priorityclass annotation to the CatalogSource object. For example: apiVersion: operators.coreos.com/v1alpha1 kind: CatalogSource metadata: name: example-catalog namespace: openshift-marketplace annotations: operatorframework.io/priorityclass: system-cluster-critical If a CatalogSource object defines both the annotation and spec.grpcPodConfig.priorityClassName , the annotation takes precedence over the configuration parameter. Additional resources Pod priority classes 4.11.3. Overriding tolerations for catalog source pods Prequisites CatalogSource object of source type grpc with spec.image defined Procedure Edit the CatalogSource object and add or modify the spec.grpcPodConfig section to include the following: grpcPodConfig: tolerations: - key: "<key_name>" operator: "<operator_type>" value: "<value>" effect: "<effect>" Additional resources Understanding taints and tolerations
