Katello 4.4.2 release process

Make this post a wiki

Roles

When Ready to Release

Release Owner

  • Request Hammer CLI Katello release from maintainers

  • Request Virt Who Configure release from maintainers

  • Request any other releases as needed from the release owners (consult the :repos: section of configs/katello/4.4.yaml)

  • Change Redmine version 4.4.2 state to Closed

  • Do Cherry-picks: Clone tool_belt

    • If any minor versions of Katello have been added to Redmine since the last cherry-pick, make sure to include them in prior_releases in configs/katello/4.4.yaml
    • Run ./tools.rb setup-environment configs/katello/4.4.yaml
    • Run GITHUB_ACCESS_TOKEN=<secret> ./tools.rb cherry-picks --version 4.4.2 configs/katello/4.4.yaml
    • Open a PR in Katello release branch. Make sure the PR name starts with [CP] to prevent our automations from adding it to Redmine issues.
    • Using git cherry-pick -x as needed, verify tickets in the cherry_picks_4.4.2 file are accounted for, or additionally cherry-pick them. Recommended: Do this in tool_belt’s checkout of Katello, in repos/katello/4.4.2/katello. This way when you run cherry-picks again, tool_belt will be aware of any picks already completed.
    • For any cherry-picks that are not needed (including Redmine trackers) you can add them to the :ignores: section of tool_belt in configs/katello/4.4.yaml
  • Check for outdated deprecation warnings in the current and next release with ./tools check-deprecation-warnings configs/katello/4.4.yaml. Follow the instructions in the output of the command. Don’t forget to create any Redmine issues needed!

  • Open a PR (or use cherry-pick PR) against the release branch which updates lib/katello/version.rb to 4.4.2:

    • git pull to make sure you have the latest changes
    • sed '/VERSION/ s/".\+"/"4.4.2"/' lib/katello/version.rb
    • Update/add the CHANGELOG.md file: GITHUB_ACCESS_TOKEN=<secret> ./tools changelog configs/katello/4.4.yaml
    • Commit: git commit -m "Release 4.4.2"
    • Ensure that the commit above is the last commit and there are no commits after it. This is the commit that will get tagged. (Rearrange commits with git rebase -i if needed.)
  • Once the PR is merged, perform the following in the Katello release branch (the real one, not your fork):

    • Tag: git tag -s -m "Release 4.4.2" 4.4.2
    • Push: git push --follow-tags (Must be pushed directly to the release branch, as pull request merges will not preserve tags.)
    • Generate source gem: gem build katello.gemspec
    • Ensure you have a working login and password at rubygems.org
    • Push gem: gem push katello-4.4.2.gem
  • Inform the delivery team that the gem is published

Once Source is Available

Note it is considered good practice to release on a day when the next day is a working day. This means no releases on Fridays or on the day before a holiday.

Release Engineer

Once release is out

Release Owner

  • Confirm response that the build succeeded (or if necessary, do more cherry-picks and version bumps repeating the steps above)
  • Test the install and upgrade documentation for both the Katello server and smart proxy
  • Post a release announcement

The release pipeline (CentOS 7 upgrade) is broken and I’m a bit confused why. There seems to be an issue with Katello 4.3 not being available at yum update time.

Okay, I think I know what happens. Nothings cleans the yum cache, and it for some reason decides not to re-fetch the Katello metadata, thus still seeing 4.2 instead of 4.3 during the 4.2→4.3 upgrade step.
(Don’t ask me why it sees Foreman, I don’t know)

That got merged, so I kicked katello-4.4-rpm-pipeline [Jenkins] again.

Thanks @evgeni! I’m really confused why the yum refresh stopped working all of a sudden. Good catch.

There never was one for the katello repo setup, only for the foreman one, but that always did suffice (as it just invalidated everything).
