Train Risky Patches Ideas

edit

🦊 GitLab Update time!

edit
  • What is GitLab?
    • An open-core venture-capital-backed clone of GitHub with more devops stuff
  • How do I login to GitLab?
    • https://gitlab.wikimedia.org + wikitech login
    • A Yubikey makes life easier here.
    • What about the underlying machines?
    • Ganeti VMs
    • gitlab1001.wikimedia,org, gitlab2001.wikimedia.org
    • gitlab deb package runs chef!
    • gitlab-ctl to do magic (rails console)
    • Ask DZahn/Jelto/Arnold on ServiceOps
  • What happens if someone asks me to do something in GitLab? Do I have powers?
    • You are almost certainly an admin.
    • Create new groups for users and projects
      • We have gitlab.wikimedia.org/repos
      • Anything that is an "official" project goes under /repos
      • Not broken up by "team" but by "area"
      • Open question: do we keep the "mediawiki/" namespace infrastructure
      • There's a phab form
      • Users are under /people
        • These users can be added under project groups
        • Pattern was stolen from KDE (like many things we're doing)
        • Project layout won't change when people groups change
  • Do we have a testing infrastructure?
  • How do I change GitLab config?
    • /etc/gitlab/gitlab.rb read by chef nonsense :D
    • this is all managed in puppet
    • Mostly we don't need to change those things
    • There's another layer of settings in the database -- this is set via the admin interface -- also contrallable via the api (and, consequently, via releng/gitlab-settings)
    • Puppet
    • https://gitlab.wikimedia.org/repos/releng/gitlab-settings
      • You'll need an API token for this
  • Do we have runners for CI?
    • Boy howdy.
    • it's complicated...
    • WMCS project: gitlab-runners (thanks Dan!)
      • These runners are available to the projects in "/repos"
    • Two other groups of runners
      • Jelto working on "Trusted" runners to build images and artifacts for production
      • Spinning up runners on public cloud k8s

Types of runners

  • Instance wide
  • Groups specific
  • Assigned to a project

Runner configuration: change it in the UI
