27.2. Uninstalling Streams for Apache Kafka using the CLI

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

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
```
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
```
