Deleting a machine
You can delete a specific machine.
Deleting a specific machine
You can delete a specific machine.
Prerequisites
-
Install an OpenShift Container Platform cluster.
-
Install the OpenShift Command-line Interface (CLI), commonly known as
oc -
Log into
ocas a user withcluster-adminpermission.
Procedure
-
View the Machines that are in the cluster and identify the one to delete:
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 MachineSet, a new machine is immediately created to satisfy the specified number of replicas.
