j7s-branch-trigger

Occasionally checks the state of branches on a provided repo using git remote ls.

If the "branches of concern" have updated since it last looked, it will send a POST to a web hook. The "branches of concern" are defined using a configured web hook.

Designed to replicate Jenkins Multibranch Pipeline triggers for Tekton in a way that is git provider agnostic.

Configuration

Configuration is done through the following environment variables which are checked at start up.

  • J7S_REPO - Required the url of the repo to check in the format you would hand git clone.
  • J7S_URL - Required the url to post to if a change is seen.
  • J7S_HISTORY_FILE - Default: '/tmp/branch-history.json' the location to save the last seen state.
  • J7S_PATTERN - Default: '^HEAD$' python flavored regex to find branches of concern, for specific branch use '^refs/heads/branch$'
  • J7S_LOOPTIME - Default: 1.0 minutes between checks of the state of of the repo
  • J7S_REPO_NAME - Default: "" the repo name which will be added to the data posted to the event. Normally the thing right before .git in the clone url.
