LUCI Configuration

This repo holds all the configuration for LUCI, the CI system Gerrit uses. You can find recent verification runs and logs at https://ci.chromium.org/ui/p/gerrit/builders.

Concepts

  • Recipe: a python script to verify a change, and a test for that verification
  • Builder: a recipe configured to run on a specific machine type
  • CQ Group: a watcher that triggers on new votes/patchsets on the specified repo+refs
  • CQ Tryjob Verifier: combines a CQ group with a builder to run a recipe when a new vote or patchset comes in

Layout

  • /main.star: overall starlark configuration for the entire host. It is also executable to generate the config data
  • /repos/*.star: repo-specific starlark configuration for builders, CQ groups, CQ tryjob verifiers, etc
  • /recipes/recipes/*.py: recipes for testing a change based on the repo
  • /recipes/recipes.py: executes recipe tests and compares/generates expected JSON goldens. 100% coverage is expected.
  • /recipes/recipe_modules/: dependencies shared by modules
  • /recipes/*.expected/*.json: expected commands executed by the recipe
  • /infra/config/recipes.cfg: versions and URLs of external recipe dependencies

Prerequisites

  • lucicfg - CLI tool to generate the configuration from the starlark scripts. To install, clone depot_tools.
  • python - Python 3, used to execute recipes.

Imporant commands

Regenerate config data after making changes (lucicfg):

$ ./main.star

Run recipe tests (python):

$ recipes/recipes.py test run

Update recipe test goldens (python):
