OpenShift - Pod stuck Terminating

If you are not familiar with the oc command, refer to OpenShift - Getting Started with the oc command.

Let's say the oc get pods command shows a pod stuck "Terminating". In this example, pod002 has been "Terminating" for 30 minutes.

oc get pods
. . .
pod001      1/1     Running        0         8d
pod002      1/1     Terminating    37        30m
pod003      1/1     Running        0         8d


Use the oc describe pod command to see if there are events that explain why the pod is stuck Terminating.

oc describe pod/pod002


Something like this could be returned.

Try to delete the pod using the oc delete pod command. Often I have observed that this command will hang and never complete.

~]# oc delete pod pod002
pod "pod002" deleted


If the prior command hangs, add the --force flag and --grace-period=0 option.

oc delete pod pod002 --force --grace-period=0


Something like this should be returned.

warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
pod "pod002" force deleted
