Description Lukasz Szaszkiewicz 2021-05-18 09:12:22 UTC 
+++ This bug was initially created as a clone of Bug #1961554 +++

ShutdownDelayDuration allows for blocking shut down for some time, e.g. until endpoints pointing to this API server have converged on all nodes. 

During this time, the API server keeps serving, /healthz will return 200, but /readyz will return failure. This is important for the graceful shutdown.

Previously the OpenShiftAPI server didn't respect this setting and could have caused some interruption to clients's requests.

--- Additional comment from Lukasz Szaszkiewicz on 2021-05-18 09:11:31 UTC ---

I think the best way to test it is to change the value manually to some high number and then trigger termination. The server should shut down after the specified time.
