Summary: In order to prevent downtime while google reprovisions certificates, we need to stage out the removal of the slackin domain from the cloud managed certs. The goal being that there's always one valid cert that doesn't need to be reprovisioned for every new release. To achieve this, we stage it out into 3 stages:
slackin.*
domain, attach this cert to the ingress in addition to our original cert.slackin.*
from the main cert.Type of change: /kind cleanup
Test Plan: Tested each stage on
testing
. After each deploy testing still had a valid cert even if one of the two was reprovisioning.
