Chapter 12. Uninstalling a cluster on Azure
You can remove a cluster that you deployed to Microsoft Azure.
12.1. 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.
While you can uninstall the cluster using the copy of the installation program that was used to deploy it, using OpenShift Container Platform version 4.13 or later is recommended.
The removal of service principals is dependent on the Microsoft Azure AD Graph API. Using version 4.13 or later of the installation program ensures that service principals are removed without the need for manual intervention, if and when Microsoft decides to retire the Azure AD Graph API.
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.
