Chapter 15. Uninstalling a cluster on Google Cloud

Procedure

1. From the directory that contains 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

   1

   For <installation_directory>, specify the path to the directory that you stored the installation files in.

   2

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

   Note

   You must specify the directory that contains 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.

Procedure

1. Set a $RELEASE_IMAGE variable with the release image from your installation file by running the following command:

   $ RELEASE_IMAGE=$(./openshift-install version | awk '/release image/ {print $3}')

2. Extract the list of CredentialsRequest custom resources (CRs) from the OpenShift Container Platform release image by running the following command:

   $ oc adm release extract \
     --from=$RELEASE_IMAGE \
     --credentials-requests \
     --included \

   1

   
     --to=<path_to_directory_for_credentials_requests>

   1

   The --included parameter includes only the manifests that your specific cluster configuration requires.

   2

   Specify the path to the directory where you want to store the CredentialsRequest objects. If the specified directory does not exist, this command creates it.

3. Delete the Google Cloud resources that ccoctl created by running the following command:

   $ ccoctl gcp delete \
     --name=<name> \

   1

   
     --project=<gcp_project_id> \

   2

   
     --credentials-requests-dir=<path_to_credentials_requests_directory> \
     --force-delete-custom-roles

   Copy to Clipboard Toggle word wrap

   1

   <name> matches the name that was originally used to create and tag the cloud resources.

   2

   <gcp_project_id> is the Google Cloud project ID in which to delete cloud resources.

   3

   Optional: This parameter deletes the custom roles that the ccoctl utility creates during installation. Google Cloud does not permanently delete custom roles immediately. For more information, see Google Cloud documentation about deleting a custom role.
