Chapter 9. Uninstalling a cluster on OpenStack
You can remove a cluster that you deployed to Red Hat OpenStack Platform (RHOSP).
9.1. Removing a cluster that uses installer-provisioned infrastructure
You can remove a cluster that uses installer-provisioned infrastructure from your cloud.
If you deployed your cluster to the AWS C2S Secret Region, the installation program does not support destroying the cluster; you must manually remove the cluster resources.
After uninstallation, check your cloud provider for any resources not removed properly, especially with User Provisioned Infrastructure (UPI) clusters. There might be resources that the installer did not create or that the installer is unable to access. For example, some Google Cloud resources require IAM permissions in shared VPC host projects, or there might be unused health checks that must be deleted.
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
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 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.
