KubeVirt CI Prow Control Plane Cluster Maintenance Window - 20th Feb. 12pm -> 21th Feb. 12pm (UTC)

[Denis Ollier Pinas]

Hi KubeVirt contributors,

The OpenShift version of the KubeVirt CI Prow Control Plane cluster is reaching its end of life in August and needs to be updated.

For this purpose, a maintenance window is scheduled to start this Friday (20th Feb.) early in the afternoon (EMEA timezone) and to finish during the week-end.

The update will be quite long since it will go through several steps before catching up the latest LTS version:

    OCP-4.16 -> OCP-v4.17 -> RHEL-9 workers -> OCP-v4.18 -> RHCOS workers -> OCP-v4.19 -> OCP-v4.20

The Prow Control Plane cluster will still be available during the update but it will experience a few hiccups.
It is expected for some ProwJobs to fail when the nodes will be evicted to be replaced by updated workers.
You might need to use `/retest` more than usual.

Unless something unexpected happens this maintenance should be quite smooth overall.

Several rehearsals were performed to reduce the risk of unforeseen events.

Don't hesitate to reach us if you have any concerns.

Regards,

The KubeVirt CI maintenance team.

Hi Denis,

The v1.8 feature freeze is scheduled for February 25th [1]. Given that there are still many VEPs that need to be merged, is it possible to postpone the maintenance until after this date?

Thanks,

Orel

Thanks for bringing this up.

The maintenance will be postponed by one week, to February 27th.

It will be pushed back further if necessary in the event that the feature freeze deadline is extended.

Thank you Denis!

The maintenance of the Prow control plane cluster is now complete.

It has been updated to the latest EUS version: OCP-v4.20.13.

The next maintenance will be to modernize Prow deployment on this cluster.
