Chapter 8. Removing Windows nodes

Procedure

1. View the machines that are in the cluster and identify the one to delete:

   $ oc get machine -n openshift-machine-api

   Copy to Clipboard Toggle word wrap

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

2. Delete the machine:

   $ 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 in preventing the machine from being deleted. You can skip draining the node by annotating "machine.openshift.io/exclude-node-draining" in a specific machine. If the machine being deleted belongs to a machine set, a new machine is immediately created to satisfy the specified number of replicas.
