Uninstalling a cluster on oVirt

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

  1. 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)
    1 For <installation_directory>, specify the path to the directory that you stored the installation files in.
    2 To view different details, specify warn, debug, or error instead of info.

    You must specify the directory that contains the cluster definition files for your cluster. The installation program requires the metadata.json file in this directory to delete the cluster.

  2. Optional: Delete the <installation_directory> directory and the OKD installation program.

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_DIR environment 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

  1. To remove the cluster, enter:

    $ ansible-playbook -i inventory.yml \
    retire-bootstrap.yml \
    retire-masters.yml   \
    retire-workers.yml

  2. Remove any configurations you added to DNS, load balancers, and any other infrastructure for this cluster.
