Easier GitHub organisation, repository and team management with github-collective

Have you ever felt that administering your GitHub organisation (or organization, depending from where you hail), its repositories, teams, and service hooks has become a tedious task and that you’d rather be doing something else?  Maybe you’re of the mindset that there should be a better way of doing things - a way that involves specific, version-controlled configuration and less repetition (less clicky-clicky).  The good news is that there is — github-collective!

This is a script, written in Python, that utilises GitHub’s JSON-based API to allow you to construct an ini-style text-based configuration representing your GitHub organisation and have this sync to create repositories and service hooks for said repositories, teams, and configure access rights.  At present, this works from your configuration to GitHub (not vice versa at present). You may already know this as what’s powering the GitHub Collective to manage repositories and teams, especially if you’re in the Plone community.

An example configuration lives within its source code repository, and similarly, the configuration that powers the Collective is available also. Effectively, you define different types of sections ([team], [hook], [repo]) and these will correspond to certain things being created on GitHub via the API.

Our implementation

We at the James Cook University eResearch Centre have deployed this for use against our GitHub organisation and our workflow looks like this:

  1. Users are able to fork a configuration repository and modify accordingly. For simplicity, since changes are frequently minor, I suggest using GitHub’s “Edit this file” feature via the web.
  2. User creates Pull Request for changes.
  3. Administrator reviews and merges changes from Pull Request.
  4. Configuration repository’s service hook sends POST to Jenkins CI instance
  5. Jenkins CI instance runs the github-collective script upon receiving this hook.
  6. Changes to configuration get enacted on GitHub.

This process is similar to what happens for the Collective, except that our service hook and Jenkins take care of making the changes happen, rather than a periodical cron job.

Our Jenkins job uses the Jenkins Text Finder plugin to search for the regex “Traceback \(most recent call last\)” in the output to determine success or failure.  This isn’t the most elegant solution in the world, but it’s good enough for now.

For what it’s worth, we have a total of 25 repositories; a similar number of teams; give or take 12 staff members in total; and the end result is that running github-collective once cached takes only around 6 seconds, including Jenkins overhead.  Unfortunately I’m unable to provide our exact configuration, but for everything we do, I’ve ‘anonymised’ the configuration and included it back in the public repository as examples. Happy to answer questions about what we’re doing too!

Thanks

All credit to Rok Garbas and Alex Clark for their work on this - it works fantastically. I can only take credit for coming in later with a few things necessary our deployment. Github-collective now supports all GitHub API settings for repositories (thus allowing you to create private repos - something critical for us, and set other metadata) and post-receive service hooks (so you can easily manage hooks on GitHub). That, and a hearty dose of end-user documentation.
