Deployment tooling/Cabal/2015-04-06

Ohai!

From https://www.mediawiki.org/wiki/Wikimedia_Release_Engineering_Team/201415Q4 : Rethinking deployment tooling and process 

• https://phabricator.wikimedia.org/T89945 (MW process)
• https://phabricator.wikimedia.org/T94620 Tooling
• https://phabricator.wikimedia.org/T93428 services
• see: http://etherpad.wikimedia.org/p/futureofdeployments

Goal of this group:     To be the team that drives improvements and vision for all deployment tooling at WMF. Short term goals of 1) making the MediaWiki deployment process streamlined and 2) setting out a vision (and rough sketch plan) for turning our mismash of tooling currently in use into a coherent "this is obviously what I want to use to do $X" collection with all the implied removal and/or additions and/or integrations.

There are a lot of good tickets in the deployment-systems project https://phabricator.wikimedia.org/tag/deployment-systems/

"Evaluate Ansible as a deployment tool" - https://phabricator.wikimedia.org/T93433 "Deployment status indicator for gerrit patches" - https://phabricator.wikimedia.org/T88136

Node.JS service template: https://github.com/wikimedia/service-template-node

Definition of done:     (Mostly?) Automated deployment without introducing opportunity for human error     Verifiable deployment (did I deploy what I wanted to deploy)     tested on staging

Goals for next week:          High level overview of how scap works currently     High level overview of how trebuchet works currently      Trebuchet: https://wikitech.wikimedia.org/wiki/Trebuchet/Design

April 6th

• We want to replace scap with Trebuchet
• Lots of talk
• Chad to talk to Ryan
  • I did!
    • Nobody's using it now, but likely to work on it again if we want it and very receptive to patches/ideas/etc.
    • Proxy idea is doable
    • Binaries still a little fuzzy. Git-annex?
