Q2 (Oct - Dec) Goals

[edit]
Previously listed goals
[edit]
  • Differential
    • fix Jenkins tests, maybe
    • migrate android
    • not a goal
  • Malu
    • pause
  • LLB + MW + Extension deploys to scap3 ?
    • not a goal
New goal proposals
[edit]
  • Python software deployment via scap3 (Zuul + Nodepool)
    • think more on it (Tyler and Antoine), not a goal for now
  • CI Tech Debt
    • Determine long term plan for Nodepool
      • This needs to be more specific
    • Anything else?
    • think about how we use queues
      • split queue per branch (eg: security releases hitting multiple branches, 600 jobs), can make more run parallel
      • SWAT deploys: make the wmf branch go through as fast as it can
      • ""Review and adjust CI queues for more parallel operations"
  • MW deploy tech debt (Experiment/Stretch)
    • scap swat
    • ability to have multiple checks on MW deploys (in addition to logstash), eg swagger spec for MW (node endpoints checking)



Q1 goal/project check-in

[edit]

Phase out Ubuntu Precise

[edit]

Replace primary production Continuous Integration host (gallium) - T95757

[edit]


Upgrade Phabricator database servers to Maria10/Jessie - T138460

[edit]
  • Yes Done

Upgrade Beta Cluster database servers to Maria10/Jessie - T138778

[edit]
  • Chad will review Dan's patches
  • Dan will coord with Jaime for $whenever_works_for_them

Move Gerrit off of ytterbium - T125018

[edit]
  • Yes Done

Reduce Technical Debt

[edit]

Perform a technical debt analysis of software and services maintained by WMF Release Engineering - T138225

Next steps:

  • Greg get the documentation documented and call it done (for this goal for this quarter)


Streamline deployments (long-lived branches)

[edit]

keyresult task:

  • Convert our production deployment strategy to use long-lived branches - T89945

project view: https://phabricator.wikimedia.org/project/view/2117/

  • Tooling will probably be done
  • static asset conclusion might not be
  • scap swat coming along nicely
    • use gerrit rest api (has need features not avail over ssh)
      • will need some sort of shared account (with frequent credential rotation, potentially each deploy)
    • can use a .netrc right now
    • scraping Deployment calendar page is crappy

Non-Quarterly goal work

[edit]

SWAT deploy changes

[edit]
  • European SWAT deploys (T137970
  • Future changes?
    • requiring a task associated with each change being pushed out?
    • Add all swatters to each swat window, stop segmenting based on their availability (worst case they get a ping when they're not online)

CI Scaling/Nodepool

[edit]

Browser tests

[edit]

Beta Cluster

[edit]
  • Long lived cherry pick stuff popping up again
  • Antoine got one out thanks to Brandon

Mukunda

[edit]

Last week

[edit]
  • Finish the `scap swat` tool which is taking shape nicely.
  • Propose Improvements to the scap remote execution api to make it easy to use from scap plugins
    • This could facilitate development of arbitrary scap checks which can be ran separately from deployments
    • Will discuss with Tyler during the deployments meeting and go from there.

This week

[edit]
  • Still finishing up scap swat
    • Hopefully, resolve the screen scraping debate
  • Start on `scap merge` branch management tooling

Tyler
