Doc Type: Bug Fix
Doc Text:
Cause: the image registry was running from sh and signals were not propagated to the image registry. Consequence: the registry wasn't able to receive SIGTERM and it took few minutes to terminate the registry pod. Fix: replace sh with the registry process using exec Result: the registry is the pid 1 process and it's able to receive SIGTERM

Comment 1 Antonio Murdaca 2019-08-05 09:07:18 UTC
Cloned the BZ because the MCO needs the fix for drain as well in 4.1, xref: https://bugzilla.redhat.com/show_bug.cgi?id=1729510
The PR linked in the MCO bugzilla is blocked on the image-registry backport (this BZ)
