branch-mirroring-action

This is a fork originating from the pixta-dev/repository-mirroring-action that focuses on a specific repo branch, not the whole repo.

A GitHub Action for mirroring a repository to another repository on GitHub, GitLab, BitBucket, AWS CodeCommit, etc.

This will copy all commits, branches and tags.

⚠️ Note that the other settings will not be copied. Please check which branch is 'default branch' after the first mirroring.

Usage

Customize following example workflow (namely replace <username>/<target_repository_name> with the right information) and save as .github/workflows/main.yml on your source repository.

To find out how to create and add the GITLAB_SSH_PRIVATE_KEY, follow the steps below:

1. How to generate an SSH key pair. Recommended encryption would be at least 2048-bit RSA.
2. Add the public key to your gitlab account
3. Add the private key as a secret to your workflow. More information on creating and using secrets.
