Deleting a specific machine

You can remove a Windows node by deleting its host Windows machine.

Deleting a specific machine

You can delete a specific machine.

You cannot delete a control plane machine.

Prerequisites

Install an OpenShift Container Platform cluster.
Install the OpenShift CLI (oc).
Log in to oc as a user with cluster-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.
