Chapter 6. Uninstalling a cluster on RHV
You can remove an OpenShift Container Platform cluster from Red Hat Virtualization (RHV).
6.1. Removing a cluster that uses installer-provisioned infrastructure
You can remove a cluster that uses installer-provisioned infrastructure from your cloud.
After uninstallation, check your cloud provider for any resources not removed properly, especially with user-provisioned infrastructure clusters. There might be resources that the installation program did not create or that the installation program is unable to access.
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
On the computer that you used to install the cluster, go to the directory that contains the installation program, and run the following command:
$ ./openshift-install destroy cluster \ --dir <installation_directory> --log-level info 1 2
NoteYou must specify the directory that contains the cluster definition files for your cluster. The installation program requires the
metadata.jsonfile in this directory to delete the cluster.-
Optional: Delete the
<installation_directory>directory and the OpenShift Container Platform installation program.
6.2. Removing a cluster that uses user-provisioned infrastructure
When you are finished using the cluster, you can remove a cluster that uses user-provisioned infrastructure from your cloud.
Prerequisites
-
Have the original playbook files, assets directory and files, and
$ASSETS_DIRenvironment variable that you used to you install the cluster. Typically, you can achieve this by using the same computer you used when you installed the cluster.
Procedure
To remove the cluster, enter:
$ ansible-playbook -i inventory.yml \ retire-bootstrap.yml \ retire-masters.yml \ retire-workers.yml- Remove any configurations you added to DNS, load balancers, and any other infrastructure for this cluster.
