Removing Windows nodes
You can remove a Windows node by deleting its host Windows machine.
Deleting a specific machine
You can delete a specific machine.
Prerequisites
Install an OKD cluster.
Install the OpenShift CLI (
oc
).Log in to
oc
as a user withcluster-admin
permission.
Procedure
View the machines that are in the cluster and identify the one to delete:
$ oc get machine -n openshift-machine-api
The command output contains a list of machines in the
<clusterid>-worker-<cloud_region>
format.Delete the machine:
$ oc delete machine <machine> -n openshift-machine-api
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.
