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!

@MusikAnimal we are testing build service. Developers can now use buildpack images.
There's a quickstart guide here.

We're also looking for feedback from the community on this service.
If your schedule allows it, kindly take a look and let us know.

As per above I was hoping to use a simple Toolforge job, but it looks like there's something amiss with the mariadb image:

tools.grantmetrics@tools-sgebastion-10:~$ toolforge-jobs run backup --command ./var/backups/backup.sh --image mariadb
tools.grantmetrics@tools-sgebastion-10:~$ cat backup.err 
mysqldump: Got error: 2002: "Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)" when trying to connect
ERROR 2002 (HY000): Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)

The relevant part of the script:

GMDIR=/data/project/grantmetrics
DATE=$(date +%Y-%m-%d)

# Dump and compress whole database.
mysqldump --defaults-extra-file=$GMDIR/replica.my.cnf \
  --single-transaction s53550__grantmetrics \
  | gzip -c > $GMDIR/var/backups/grantmetrics_$DATE.sql.gz

I can try using the Build Service instead, but as this is such a tiny backup script, I thought the vanilla Jobs framework would be better.

This is a reminder that the tool for which this ticket is created is still running on the Grid.
The grid is deprecated and all remaining tools need to migrate to Toolforge Kubernetes.

We've sent several emails to maintainers as we continue to make the move away from the Grid.
Many of the issues that have held users back from moving away from the Grid have been addressed in
the latest updates to Build Service. See: https://wikitech.wikimedia.org/wiki/Portal:Toolforge/Changelog
