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
. . .
NAME        READY   STATUS         RESTARTS  AGE
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.

Events:
  Type     Reason     Age                  From                 Message
  ----     ------     ----                 ----                 -------

  Normal   Killing    3m (x41 over 10d)    kubelet, node001  Killing container with id docker://pod002:Container failed liveness probe.. Container will be killed and recreated.

 

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
