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 Copy linkLink copied to clipboard!
You can remove a cluster that uses installer-provisioned infrastructure that you provisioned from your cloud platform.
After uninstallation, check your cloud provider for any resources that were not removed properly, especially with user-provisioned infrastructure clusters. Some resources might exist because either the installation program did not create the resource or could not access the resource.
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 has 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
$ ./openshift-install destroy cluster \ --dir <installation_directory> --log-level infoCopy to Clipboard Copied! Toggle word wrap Toggle overflow where:

- Specify the path to the directory that you stored the installation files in.
- --log-level info
To view different details, specify
warn,debug, orerrorinstead ofinfo.NoteYou must specify the directory that includes 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 Copy linkLink copied to clipboard!
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 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:Copy to Clipboard Copied! Toggle word wrap Toggle overflow where:
<name>- Matches the name that was originally used to create and tag the cloud resources.
<azure_region>- is the Azure region in which to delete cloud resources.
<azure_subscription_id>- is the Azure subscription ID for which to delete cloud resources.
Verification
- To verify that the resources are deleted, query Azure. For more information, refer to Azure documentation.
