Chapter 6. Uninstalling a cluster on Azure
You can remove a cluster that you deployed to Microsoft Azure.
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 (UPI) clusters. There might be resources that the installer did not create or that the installer 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
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.
6.2. Deleting Microsoft Azure resources with the Cloud Credential Operator utility
After uninstalling an OpenShift Container Platform cluster that uses short-term credentials managed outside the cluster, you can use the CCO utility (ccoctl) to remove the Microsoft Azure (Azure) resources that ccoctl created during installation.
Prerequisites
-
Extract and prepare the
ccoctlbinary. - Uninstall an OpenShift Container Platform cluster on Azure that uses short-term credentials.
Procedure
Delete the Azure resources that
ccoctlcreated by running the following command:$ ccoctl azure delete \ --name=<name> \1 --region=<azure_region> \2 --subscription-id=<azure_subscription_id> \3 --delete-oidc-resource-group
Verification
- To verify that the resources are deleted, query Azure. For more information, refer to Azure documentation.
