Beta Cluster stability

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

• Availability graphs: https://graphite.wmflabs.org/dashboard/#availability
  • So far we are averaging about 99.5% availability and this is counting 404 as non-availability so that is fairly good IMO.

Test history

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

• Elasticsearch logging of Cucumber results is almost complete
• Will start dashboard development this week (this is late obviously, but I'd like another week or so to work on it)

Isolated CI instances

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

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

• Zuul package almost done. Will deploy it on some labs instance this week
  • Related doc pending
• Quick presentation meeting with Andrew/Chase Wednesday

• Timo / Kunal continued on:
  • reducing the number of jobs (faster JJB deploys, less VM to spawn later on)
  • skiping full git clones
  • switch mw jobs from sqlite to mysql (official announcement pending)
• phantomjs -> chromium/karma (faster runs!!)

• Need a champion for "reduce copies of mediawiki/core in workspaces" https://phabricator.wikimedia.org/T93703
