Last week notes https://www.mediawiki.org/wiki/Wikimedia_Release_Engineering_Team/Checkin_archive/20150421#Scrum_of_Scrums

Do these CI tasks need to be tracked for SoS? https://phabricator.wikimedia.org/T72068 https://phabricator.wikimedia.org/T88798

Beta Cluster stability / Staging

https://phabricator.wikimedia.org/project/board/497/?order=priority

Quarterly Priority: Green nightly builds on staging: https://phabricator.wikimedia.org/T88701

Quarterly Priority: Stable uptime metrics of the Staging cluster: https://phabricator.wikimedia.org/T88705

• Unstable last week due to mgiration to new labs hardware yeah!, scap, disk full, mw stacktracing...
• https://graphite.wmflabs.org/dashboard/#availability
• Request from Andrew: If there are any instances that can be easily destroyed + recreated, please do (eg in staging?)
• Scap $TMPDIR craziness causing scap failures

Deployment Cabal

Took a step back from fighting over salt/ansible/trebuchet/scap and decided to make a common model for ideal deployments.

• Once we have a shared vision, it's easier to decide what tools to use
• Will define clear steps and requirements for each of those steps
• Will take existing service deploys, MW code deploys, trebuchet-based deploys all into account
• https://phabricator.wikimedia.org/T97068 might eventually contain details about this grand vision

Test history

Quarterly Priority: By team test history: https://phabricator.wikimedia.org/T88706

• Gerrit repo https://gerrit.wikimedia.org/r/#/admin/projects/integration/raita
• Spinning up an integration-raita instance today (elasticsearch + tiny JS app)
  • Needs to be publically accessible (labs web proxy? antoine: yeah, easy to setup via https://wikitech.wikimedia.org/wiki/Special:NovaProxy )
• ElasticSearch puppet role & module? Chad can help.

Isolated CI instances

https://phabricator.wikimedia.org/tag/continuous-integration/board/?order=priority

Quarterly Priority: Disposable VMs - https://phabricator.wikimedia.org/T47499

• Bump openstack flavor ci1.medium from 30GB to 40GB disk space https://phabricator.wikimedia.org/T96706#1230309
• Antoine played with http://docs.openstack.org/developer/diskimage-builder/ to create a labs image. Nothing good came out of it yet. Not sure how to bootstrap an image appropriately for wmflabs context (ie setup DNS / puppet ...).

MediaWiki Releases
