Team discussions[edit]
Quickies[edit]
- Chad demo of harbor
- Harbor evaluated 5 years ago
- GC with younggen
- Helm chart repo
- OIDC
- Preseeding with dragonfly
- Stable + mature
- Terraform provider as well
- Webhooks for events
- Prometheus endpoint
- Running on test k8s in DO
- Questions:
- Configurable outside GUI? Yep, full API, programatic managment
- Quarter goals: https://www.mediawiki.org/wiki/Wikimedia_Release_Engineering_Team/Goals/202223Q3
- Mise-en-place goals: https://www.mediawiki.org/wiki/Wikimedia_Release_Engineering_Team/Sprint/GitLab_mise_en_place
- Still waiting on this? give releng access to logs to debug buildkit-to-wmf-registry publishing?
Backport forbidden patch types[edit]
- "Forbidden patch types": https://wikitech.wikimedia.org/wiki/Backport_windows
- "Single patches that require more than one sync - in other words, changes to multiple files which depend on each other."
- Do we care with k8s + scap backport
- New problems: extension.json parsed outside of php restart :D https://wikitech.wikimedia.org/wiki/Incidents/2023-01-17_MediaWiki
- Ignored in practice for years
- TODO: tweak language, still somewhat needed. Goes away on Full K8s -- thcipriani
GitLab Migrations[edit]
- https://phabricator.wikimedia.org/T273525
- Still needed: branch renaming for master→main for tools-release
- How/when do we want to handle that in the process of migration?
Discussion[edit]
- We have to do it :)
- In between time: useful to have master branch in gerrit, have two branches in gitlab, then change default upstream
- Moving over to main a pre-req for gitlab?
- Zuul will only work with master in gerrit
- Leave master branch for a while? Create new refs/heads/main?
- TODO: create a "main" on repos/releng/release, leave master for now, deal with fallout later -- thcipriani
[edit]
- One of our goals: Launch instance-wide runners
- Same sprint as scaling buildkitd
- Interest in IRC/Slack in using Kokkuri, blocked on runner availability
- Talked to a few of you in 1-on-1s about ideas for this, better to talk together
Discussion[edit]
- FInish out the sprint, it's the last thing, then we'll be done
- Value in getting kokkuri usage
- Let's let people use WMCS with the knowlege that they'll run into space issue?
- Better to let people have early access knowing their jobs will be slower?
- We can continue to promise things will get better'
- Plus things get better magically
- Approach: have instance-wide runners pick them up (which would be WMCS), then after sprint have scalable buildkitd, then what do with WMCS runners?
- Leave around for special cases or retire?
- Alternative: up replicaset and make DO available now and continue working on autoscaling seperately?
- Proposal: Enable WMCS runners site-wide, continue hacking on buildkitd hacking, reassess
- TODO: dancy to make wmcs instance-wide/work with brennen
- May be a matter of changing the registration token for the runners
