+++ This bug was initially created as a clone of Bug #1843187 +++ When pod expectations are not met, status for workloads can wedge. When status for workloads wedges, operators wait indefinitely. When operators wait indefinitely status is wrong. When status is wrong, upgrades can fail. Picking https://github.com/kubernetes/kubernetes/pull/91008 seems like a fix. --- Additional comment from Maciej Szulik on 2020-06-03 12:54:58 CEST ---
