Deployment tooling/Cabal/2016-11-14

Latest Version (3.3.1-1)

Been live on beta since Thursday – please test if you haven't already.

Changelog

https://phabricator.wikimedia.org/P4408

It's a big one. Will send email post-release.

Next release/blocking

Possibly another release before 3.4.0. Depends on bugfixes, etc.

• Canary doesn't rollback if you don't continue - enhancement probably needed
• Allow failures for a percentage of targets - enhancement related, somewhat
• Scap rollback behavior
• canonical target list (ops controls targets)
  • In etcd
  • LVS does know specific hosts
• --version flag

• TODO Cherry picking on deployment host doesn't work for targets
• Rollback failures happen when a host is unreachable, which means that it gives up without restoring all hosts.
  • Why something failed (different types of errors)
  • Doesn't continue rollback for targets that pass the stage
  • connection failure vs. threshold
    • does the threshold take care of scap understanding the different type of errors?
• TODO Add SHA1 to deployment messages

Blocked

Needs review

• Flatten MediaWiki deploy into a single git repo
