Team Business[edit]

Updates[edit]

  • Chad :(
  • Train/SoS rotation proposal while we're down a person:
    • Train: Include Antoine/Zeljko into the rotation and move the train deployment time to a EU-friendly time during those weeks
    • something else.. ?
    • DECIDED: spread the pain across all (Antoine, Dan, Mukunda, Tyler, Zeljko, with JR after the first rotation)
    • DECIDED: for weeks when it's EU people doing it we'll move the train window to a EU-centric time slot
    • ACTION: Tyler to setup a branch cut hangout for this week's train (eg: tomorrow)
    • DECIDED: AUTOMATE TEH SHIT OUT OF IT


Offsite notes and action items[edit]

Data Data Data[edit]

  • Talk with Analytics - JR
  • Talk with CE/Bitergia - JR
  • Explore Bitergia - JR
  • Identify data sources we want to collect - RelEng (who know what systems)
  • Erik Bernhardson / Guillaume Lederrey
    • After we get our list of data sources talk to them

SWATs/Trains[edit]

  • TODO: Tyler reasses scap swat in mw-config from Mukunda
  • Look into parsing scap messages for known patterns and pulling out the data
  • Look into enabling scap start/done
  • Look into recording if mwdebug was used during the deploy (eg: 'scap stage')
  • H/Now will we get time for this?
  • Have Mukunda do a couple weeks of SWATs
    • Mukunda has a lot to say about this subject.... writeup incoming

TODO tl;dr: Tyler taskify the above and talk to Mukunda

Staging[edit]

  • Greg to talk with Deb about what to do next with talking to Victoria
    • Done
  • Greg to figure out how we can better market what we are accomplishing (eg "monthly showcase")
    • TODO
  • Get a k8s cluster from SRE for CI to deploy to.
    • Dan/Tyler discuss later today
      • potentially poke/get a committment on a timeline soon

Release Engineering[edit]

  • Blocking
  • Blocked
  • Updates
    • Heads up: There will be more people in the normal MW Train deployment rotation (namely: Antoine, Zeljko, and Dan to start)
    • Heads up: There is a new primary deployment host, deploy1001.eqiad.wmnet (tin is gone)
    • Reminder: just use deployment.eqiad.wmnet for ssh
  • Quarterly cross-dependencies
