Team discussions

Contint Decomm

Move Phab to Phorge

  • Build a testing plan—happy path of workflows
  • Investigate aphlict upgrade

Next sprint!

Phab stuff

edit

Objective: prepare for bullseye upgrade

  • 7.4 incompatibilities
  • Get our repo in-order vs upstream (stack patches better)
  • Stretch: pair on deploys
  • Upgrade dev-tools instance?
  • Via Jaime 1-on-1: develop environment

PipelineLib → GitLab

edit

Objective: Migrate 1 SRE service thing

  • GitLab running out of diskspace https://phabricator.wikimedia.org/T340887
    • storage the for the registry—we have a device we can use for storage space
    • Bigger instances
    • Restarting BuildKitd on a timer
    • Figure out how to reduce the number of jobs running on WMCS runners
      • 1031 is instance-wide
      • Common patterns may not work here since there's no registry
      • WMCS vs K8s runners
        • There are pros and cons
        • Proposal: Disable WMCS runners for a week and track the impact
  • Collect data about job failures/job run time
