Chapter 10. Removing Windows nodes

Procedure

1. View the machines that are in the cluster by running the following command:

   $ oc get machine -n openshift-machine-api

   Copy to Clipboard Toggle word wrap

   The command output contains a list of machines in the <clusterid>-<role>-<cloud_region> format.

2. Identify the machine that you want to delete.

3. Delete the machine by running the following command:

   $ oc delete machine <machine> -n openshift-machine-api

   Copy to Clipboard Toggle word wrap
   Important

   By default, the machine controller tries to drain the node that is backed by the machine until it succeeds. In some situations, such as with a misconfigured pod disruption budget, the drain operation might not be able to succeed. If the drain operation fails, the machine controller cannot proceed removing the machine.

   You can skip draining the node by annotating machine.openshift.io/exclude-node-draining in a specific machine.

   If the machine that you delete belongs to a machine set, a new machine is immediately created to satisfy the specified number of replicas.
