Uninstalling a cluster on IBM PowerVC

You can remove a cluster that you deployed to IBM PowerVC using the installation program.

Removing a cluster that uses installer-provisioned infrastructure

To remove an OpenShift Container Platform cluster that uses installer-provisioned infrastructure, you can use the installation program and the installation files from your original deployment to uninstall the cluster from your cloud platform.

Note

After uninstallation, check your cloud provider for any resources that were not removed properly, especially with user-provisioned infrastructure clusters. Some resources might exist because either the installation program did not create the resource or could not access the resource.

Prerequisites

• You have a copy of the installation program that you used to deploy the cluster.
• You have the files that the installation program generated when you created your cluster.

Procedure

1. From the directory that has the installation program on the computer that you used to install the cluster, run the following command:

   $ ./openshift-install destroy cluster \
   --dir <installation_directory> --log-level info
   

   where:

   <installation_directory>

   Specify the path to the directory that you stored the installation files in.

   --log-level info

   To view different details, specify warn, debug, or error instead of info.

   Note

   You must specify the directory that includes the cluster definition files for your cluster. The installation program requires the metadata.json file in this directory to delete the cluster.

2. Optional: Delete the <installation_directory> directory and the OpenShift Container Platform installation program.
