rename_default_branch

This will find all projects accessible by the API token, filterable by namespace and project. It will skip any repository that already had a main branch.

• Create a new branch main copied from master.
• Copy branch protection rules from master to main.
• Re-target any pull requests from master to main.
• Update any scheduled pipelines referencing master.
• Update any webhooks referencing master.
• Delete the master branch.
• Create a new branch protection rule for master preventing any future pushes.

NOTE: For a premium subscriber it'd be required to implement a few more parts of the protection API. This will not copy user/group protections.

Setup

$ pipenv install

Authentication

Create a gitlab personal access token with api scope and export it into the env:
