In The Lifecycle of a Pod I read:

In general, pods which are created do not disappear until someone destroys them. This might be a human or a ReplicationController, or another controller. The only exception to this rule is that pods with a PodPhase of Succeeded or Failed for more than some duration (determined by the master) will expire and be automatically reaped.

I create pods with RestartPolicy = Never, but after completion (status Succeeded) they do not get reaped.

Please advice.
