第 4 章 Deleting a machine

Procedure

1. 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.

2. Delete the machine:

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

   重要

   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.
