Description Antonio Murdaca 2019-10-21 08:26:00 UTC

+++ This bug was initially created as a clone of Bug #1763635 +++

Description of problem:

During a 4.1.z to 4.2.z upgrade the etcd-member.yaml master manifest is being rendered with an empty image reference by the MCO (which is where the template lives and the render happens).
As a result, etcd fails to run, etcd-quorum-guard is fooled and the upgrade completely disrupts the cluster as it loses quorum.


Version-Release number of selected component (if applicable):

from 4.1 onwards

How reproducible:

1/20

Steps to Reproduce:
1. CI and or manual testing, 1/20 will fail
2.
3.

Actual results:

cluster disruption

Expected results:

upgrade successful
