Chapter 31. Uninstalling Streams for Apache Kafka

You can uninstall Streams for Apache Kafka on OpenShift 4.12 and 4.14 to 4.17 from the OperatorHub using the OpenShift Container Platform web console or CLI.

Use the same approach you used to install Streams for Apache Kafka.

When you uninstall Streams for Apache Kafka, you will need to identify resources created specifically for a deployment and referenced from the Streams for Apache Kafka resource.

Such resources include:

  • Secrets (Custom CAs and certificates, Kafka Connect secrets, and other Kafka secrets)
  • Logging ConfigMaps (of type external)

These are resources referenced by Kafka, KafkaConnect, KafkaMirrorMaker, or KafkaBridge configuration.

Warning

Deleting CRDs and related custom resources

When a CustomResourceDefinition is deleted, custom resources of that type are also deleted. This includes the Kafka, KafkaConnect, KafkaMirrorMaker, and KafkaBridge resources managed by Streams for Apache Kafka, as well as the StrimziPodSet resource Streams for Apache Kafka uses to manage the pods of the Kafka components. In addition, any OpenShift resources created by these custom resources, such as Deployment, Pod, Service, and ConfigMap resources, are also removed. Always exercise caution when deleting these resources to avoid unintended data loss.

This procedure describes how to uninstall Streams for Apache Kafka from the OperatorHub and remove resources related to the deployment.

You can perform the steps from the console or use alternative CLI commands.

Prerequisites

  • Access to an OpenShift Container Platform web console using an account with cluster-admin or strimzi-admin permissions.

  • You have identified the resources to be deleted.

    You can use the following oc CLI command to find resources and also verify that they have been removed when you have uninstalled Streams for Apache Kafka.

    Command to find resources related to a Streams for Apache Kafka deployment

    oc get <resource_type> --all-namespaces | grep <kafka_cluster_name>

    Replace <resource_type> with the type of the resource you are checking, such as secret or configmap.

Procedure

  1. Navigate in the OpenShift web console to Operators > Installed Operators.

  2. For the installed Streams for Apache Kafka operator, select the options icon (three vertical dots) and click Uninstall Operator.

    The operator is removed from Installed Operators.

  3. Navigate to Home > Projects and select the project where you installed Streams for Apache Kafka and the Kafka components.

  4. Click the options under Inventory to delete related resources.

    Resources include the following:

    • Deployments
    • StatefulSets
    • Pods
    • Services
    • ConfigMaps
    • Secrets
    Tip

    Use the search to find related resources that begin with the name of the Kafka cluster. You can also find the resources under Workloads.

Alternative CLI commands

You can use CLI commands to uninstall Streams for Apache Kafka from the OperatorHub.

  1. Delete the Streams for Apache Kafka subscription. 

    oc delete subscription amq-streams -n openshift-operators

  2. Delete the cluster service version (CSV). 

    oc delete csv amqstreams.<version>  -n openshift-operators

  3. Remove related CRDs. 

    oc get crd -l app=strimzi -o name | xargs oc delete

31.2. Uninstalling Streams for Apache Kafka using the CLI
Link kopieren

This procedure describes how to use the oc command-line tool to uninstall Streams for Apache Kafka and remove resources related to the deployment.

Prerequisites

  • Access to an OpenShift cluster using an account with cluster-admin or strimzi-admin permissions.

  • You have identified the resources to be deleted.

    You can use the following oc CLI command to find resources and also verify that they have been removed when you have uninstalled Streams for Apache Kafka.

    Command to find resources related to a Streams for Apache Kafka deployment

    oc get <resource_type> --all-namespaces | grep <kafka_cluster_name>

    Replace <resource_type> with the type of the resource you are checking, such as secret or configmap.

Procedure

  1. Delete the Cluster Operator Deployment, related CustomResourceDefinitions, and RBAC resources.

    Specify the installation files used to deploy the Cluster Operator. 

    oc delete -f install/cluster-operator

  2. Delete the resources you identified in the prerequisites. 

    oc delete <resource_type> <resource_name> -n <namespace>

    Replace <resource_type> with the type of resource you are deleting and <resource_name> with the name of the resource.

    Example to delete a secret

    oc delete secret my-cluster-clients-ca-cert -n my-project
