T236576: Move all Wikimedia CI (WMCS integration project) instances from jessie to stretch || NOTYETCREATED
Most instances are currently running Stretch; we should plan to migrate them over to Buster or Bullseye ahead of the deadline (WHEN?).
Full list: https://openstack-browser.toolforge.org/project/integration and https://os-deprecation.toolforge.org/stretch/integration.html
Stretch-based machines as of 2022-01-26:

Mentioned in SAL (#wikimedia-releng) [2021-09-10T21:52:27Z] <James_F> Created experimental integration-agent-docker-1021 for T252071
To summarize, we would need a flavor of instances that has more disks:
This is ready to be done and there is already an integration-agent-docker-1023.
I have updated the setup documentation: https://wikitech.wikimedia.org/wiki/Nova_Resource:Integration/Setup

I have created and pooled integration-agent-puppet-docker-1003 so we can put it online and put the old one integration-agent-puppet-docker-1002 offline to switch the Puppet job. It will have to be verified, but at least Docker seems to work properly.

[operations/puppet@production] ci: relocate castor storage directory
@hashar, it looks like integration-castor04 is up and perhaps working now? Does that mean we can kill integration-castor03 and declare this done?
The new instance is provisioned indeed but the migration has not yet happened. I notably need to get the couple pending Puppet patches merged.
For the migration:
I will look at getting the puppet patch merged ( https://gerrit.wikimedia.org/r/774525 and https://gerrit.wikimedia.org/r/774771 ) then commit to do the migration during the morning when CI is quiet. From the note I wrote in my last comment, it should be a rather quick migration.
Thank you @komla for the ping :)
getting the puppet patch merged ( https://gerrit.wikimedia.org/r/774525 and https://gerrit.wikimedia.org/r/774771 )
Please add some reviewers to get patches merged.
A side effect is that Bullseye instances do not have Diamond/Graphite monitoring. I filed T307655 to find a replacement (likely Prometheus?)

I had to delete integration-castor04 because it had some issue after being migrated earlier this week.
The new one is integration-castor05 with IP 172.16.1.98, I have attached the volume and ran wmcs-prepare-cinder-volume.
Mentioned in SAL (#wikimedia-releng) [2022-05-06T12:55:41Z] <hashar> Migrated Castor service from integration-castor03 to integration-castor05 # T252071
After 3 years and 2 months integration-castor03 is gone. That was the last Stretch instance in the integration project.
I have added some updates to https://www.mediawiki.org/wiki/Continuous_integration/Architecture/Castor
Mentioned in SAL (#wikimedia-releng) [2022-05-18T07:32:12Z] <hashar> Deleting Jenkins agent configuration for integration-castor03 # T252071
Part of this task relocated the Castor instance and I took that opportunity to also change the directory layout for the service. As a result we have been serving stall caches for quite a while. T323051 fixes it.
