rieske / multi-repo-upgrades

You haven't followed the monorepo antipattern and have your services and libraries contained in repositories. Yet there are cases when you need to change something across them all. It doesn't need to be painful.

Perform upgrades across multiple repositories

Prerequisites

• install https://github.com/lindell/multi-gitter
• create a GH PAT for your GitHub organization and export it to your env as GITHUB_TOKEN. The permissions that the PAT needs are:
  • Repository access: All repositories (so that it can read repositories)
  • Repository permissions:
    • Contents: Read and write (so that we can clone and push a new branch)
    • Pull requests: Read and write (so that we can create a PR)

Running the upgrade

./mass-pr.sh some-version-perhaps

This will create a series of PRs in each repo.

How this works

The multi-gitter tool will clone all the repos and run the given script against the cloned contents before pushing the changes to a branch and creating a PR. The script upgrade.sh is executed per each cloned repo. The script can contain simple seds to replace a line in some file (a version perhaps), or it can contain more complex modifications. The provided script contains some samples.
