Event Timeline

My apologies if this ticket comes as a surprise to you. In order to ensure WMCS can provide a stable, secure and supported platform, it’s important we migrate away from GridEngine. I want to assure you that while it is WMCS’s intention to shutdown GridEngine as outlined in the blog post https://techblog.wikimedia.org/2022/03/14/toolforge-and-grid-engine/, a shutdown date for GridEngine has not yet been set. The goal of the migration is to migrate as many tools as possible onto kubernetes and ensure as smooth a transition as possible for everyone. Once the majority of tools have migrated, discussion on a shutdown date is more appropriate. See T314664: [infra] Decommission the Grid Engine infrastructure.

As noted in https://techblog.wikimedia.org/2022/03/16/toolforge-gridengine-debian-10-buster-migration/ some use cases are already supported by kubernetes and should be migrated. If your tool can migrate, please do plan a migration. Reach out if you need help or find you are blocked by missing features. Most of all, WMCS is here to support you.

However, it’s possible your tool needs a mixed runtime environment or some other features that aren't yet present in https://techblog.wikimedia.org/2022/03/18/toolforge-jobs-framework/. We’d love to hear of this or any other blocking issues so we can work with you once a migration path is ready. Thanks for your hard work as volunteers and help in this migration!

No need to apologize. I'm aware of the upcoming migration since a couple of months and even tried to do it for my tools back in May (?), but failed due to my inexperience with Kubernetes and decided to (temporarily) settle with the Buster alternative instead. I'll give it another try soon.

@Tkarcher Hi! Have you been able to migrate your tool to the new platform? Let me know if you are having issues or want some help (if so, having the url to the code on gitlab or wherever would help greatly to send patches and such).

Sorry! I migrated Klexibot some time ago already, but forgot to close this task here. I see the bot running on Kubernetes:

tools.klexibot@tools-sgebastion-10:~$ toolforge-jobs list
/usr/bin/toolforge-jobs:15: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
 from pkg_resources import load_entry_point
Job name:    Job type:         Status:
-----------  ----------------  ----------------------------------------
mk-linker    schedule: @daily  Last schedule time: 2024-02-05T01:53:00Z

And I don't see any jobs running on the grid in the last seven days: https://grid-deprecation.toolforge.org/t/klexibot

So unless you see something which I don't see, I consider this task as done / resolved.
