Chapter 15. Uninstalling a cluster on GCP

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

   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. Obtain the OpenShift Container Platform release image 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 --credentials-requests \
     --cloud=gcp \
     --to=<path_to_directory_with_list_of_credentials_requests>/credrequests \

     $RELEASE_IMAGE

   credrequests is the directory where the list of CredentialsRequest objects is stored. This command creates the directory if it does not exist.

3. Delete the GCP resources that ccoctl created:

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

   1

   
     --project=<gcp_project_id> \ 

   2

   
     --credentials-requests-dir=<path_to_directory_with_list_of_credentials_requests>/credrequests

   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 GCP project ID in which to delete cloud resources.
