Checking `kube_replicaset_spec_replicas{namespace="openshift-authentication",replicaset=~"oauth-openshift-65d76d9bcd"}`, the value was set to 3 the whole time. Meaning something just deleted the pods one by one.

Although, the same can be observed with openshift-apiserver instances (see `kube_deployment_status_replicas_available{namespace="openshift-apiserver"}`).

Conclusion:
1. Master nodes are drained one by one (approximately after 5 minute of each other).
2. Both apiserver/oauth-openshift pods do not have enough time to get back running/available in time.
3. There's no PDB that can avoid draining two apiserver/oauth-openshift instances at the same time so the number of available instances dropped from 3 to 1 at some point.

Current behavior:
- Both apiserver/oauth-openshift operators changes condition/Degraded to true when there's at least one replicas missing.

Expected behavior:
- The operators allow 1 replica to be unavailable and change condition/Degraded to true only when there are at least 2 replicas unavailable (since both deployments set maxUnavailable to 1)
- PDB is defined to avoid 2 unavailable replicas at the same time

Comment 1 Jan Chaloupka 2021-11-25 15:27:56 UTC
Will need more time to properly improve the logic for setting the operator Degraded condition

Comment 4 Rahul Gangwar 2021-12-06 10:11:55 UTC
Checked the last few runs of CI jobs and verified through https://promecieus.dptools.openshift.org/, there's at most 1 unavailable replica for kube_deployment_status_replicas_available{namespace="openshift-apiserver"} and kube_deployment_status_replicas_available{namespace="openshift-authentication"}
