Chapter 5. Deleting a machine
Chapter 5. Deleting a machine You can delete a specific machine. 5.1. Deleting a specific machine You can delete a specific machine. Note 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: USD 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: USD oc delete machine <machine> -n openshift-machine-api 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. 5.2. Additional resources Replacing an unhealthy etcd member .
