WIkiDev16[edit]


Other[edit]


Staging
  • Let's not do this
  • Explore the idea: https://phabricator.wikimedia.org/T115497 Survey on needs related to Beta Cluster/Staging
  • Roll the ideas from staging into beta? Auto-provisioning, recent distros, puppet cleanup, etc?
  • End goal: make sure problems in production are reproducible
  • Moving target trying to keep up with ops
    • ACTION: schedule time with ops to discuss dedicated opsen to help plan/review/merge
      • Promote shared ownership of ops/puppet related to BC/Prod
      • Talk about practices around puppet manifests (improvements in envirinment neutrality, taking care of existing debt)
    • Why?
      • reduce tech debt
      • fewer times bugging ops for help :)
      • making production errors (more) reproducible on Beta Cluster
      • helps find the gross corner cases in prod puppet (eg: tin, you can't just apply the deployment:: role on it and have it work)
  • Differential
    • Rfc on track for end of Q2/Dev Summit
    • Q3 will likely be spent responding to concerns, defining workflows, planning for migration
    • Will not be rolling out or performing any substantial migration
    • find more standalone/early adopter projects
    • End of Q3/early Q4 for MW and extensions moving over


  • QA Health Dashboard
    • What is the scope/purpose of this project?
      • One possibility is to show (us?) which projects are using which libraries/versions, data on unit/integration tests, coverage, etc.
      • API for querying this data would allow for ad hoc, more team specific dashboards

  • Additional zuul-merger on labs host (Tomorrow 3pm UTC with Andrew B.)
  • Tyler/Mukunda got rid of ZUUL_UID for the publish jobs, let us push doc from Differential.
  • random reviews and infra related stuff (Zuul/Nodepool package updates)
  • zuul-cloner ready to clone from local mirrors
  • rake entry point being generalized

(Greg can create some tasks for these if/as needed)

  • Antoine + Mukunda should sit down and talk CI/Harbormaster/Nodepool
    • Mukunda just needs to find time to finally test out harbormaster triggering jenkins jobs.
  • Find some Differential Ambassadors for each vertical
    • bd808 for Reading
