Chapter 11. Uninstalling AMQ Streams You can uninstall AMQ Streams on OpenShift 4.6 to 4.10 from the OperatorHub using the OpenShift Container Platform web console or CLI. Use the same approach you used to install AMQ Streams. When you uninstall AMQ Streams, you will need to identify resources created specifically for a deployment and referenced from the AMQ Streams 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 CustomResourceDefinitions results in the garbage collection of the corresponding custom resources ( Kafka , KafkaConnect , KafkaMirrorMaker , or KafkaBridge ) and the resources dependent on them (Deployments, StatefulSets, and other dependent resources). 11.1. Uninstalling AMQ Streams from the OperatorHub using the web console This procedure describes how to uninstall AMQ Streams 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 AMQ Streams. Command to find resources related to an AMQ Streams 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 Navigate in the OpenShift web console to Operators > Installed Operators . For the installed Red Hat Integration - AMQ Streams operator, select the options icon (three vertical dots) and click Uninstall Operator . The operator is removed from Installed Operators . Navigate to Home > Projects and select the project where you installed AMQ Streams and the Kafka components. 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 AMQ Streams from the OperatorHub. Delete the AMQ Streams subscription. oc delete subscription amq-streams -n openshift-operators Delete the cluster service version (CSV). oc delete csv amqstreams. <version> -n openshift-operators Remove related CRDs. oc get crd -l app=strimzi -o name | xargs oc delete 11.2. Uninstalling AMQ Streams using the CLI This procedure describes how to use the oc command-line tool to uninstall AMQ Streams and remove resources related to the deployment. Prerequisites 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 AMQ Streams. Command to find resources related to an AMQ Streams 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 Delete the Cluster Operator Deployment , related CustomResourceDefinitions , and RBAC resources. Specify the installation files used to deploy the Cluster Operator. oc delete -f amq-streams- <version> /install/cluster-operator 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 -n my-project

Commands:
get <resource_type> --all-namespaces | grep <kafka_cluster_name>
delete subscription amq-streams -n openshift-operators
delete csv amqstreams. <version> -n openshift-operators
get crd -l app=strimzi -o name | xargs oc delete
get <resource_type> --all-namespaces | grep <kafka_cluster_name>
delete -f amq-streams- <version> /install/cluster-operator
delete <resource_type> <resource_name> -n <namespace>
delete secret my-cluster-clients-ca -n my-project
