We noticed that we didn't get explicitly informed about upgrades which are stuck due to a missing admin ack. We can already check if an upgrade won't succeed due to a missing admin ack with cluster_operator_conditions{condition="Upgradeable",endpoint="metrics",name="version",reason="AdminAckRequired"} == 0
, but we should write a more sophisticated query which takes into account the current and desired cluster version for the running upgrade job, and which fires when the upgrade job tries to do a minor upgrade which can't succeed due to the missing admin ack.
Additionally, we didn't realize that maintenance was stuck on one cluster for >10h due to the missing admin ack. We should add an alert for upgrade jobs which have been running for longer than 6 hours or so (exact duration TBD).
OpenShift requires a manual admin ack when upgrading minor versions. See Providing the administrator acknowledgment.
If we set a release channel in project syn we implicitly acknowledge that a minor upgrade can be done.
We have had cases where we forgot to do the admin ack after a channel upgrade and this did lead to mainenance/on-call alerts.
We should automate the admin ack.
Do manual work and get on-call alerts.
