Hey all!

I’m helping migrate a few teams from different places — TFS, Azure DevOps, Stash/Bitbucket, into GitHub. And one feature that all those services offer is setting the default permissions for all repos created in different organizations or projects. Stuff like, set the number of reviewers whom need to approve a PR before it can be merged, or set permissions for different teams to new repos.

GitHub interestingly doesn’t do that(!), and requests to our GitHub Enterprise team suggested we go and build it ourself. I’m surprised this is something I need to build myself — shouldn’t Enterprises and Orgs have trickle-down permissions and settings that can be automatically enforced?

But build it myself is exactly what I did. Using GitHub’s admittedly quite robust REST API, I built a GitHub Action that reads a CSV of repos and settings flags (more on this below), to send authenticated curls to GitHub’s REST APIs to set permissions. Then we read the output of the curl to make sure it worked properly.
