 3 | [![Test](https://github.com/pixta-dev/repository-mirroring-action/actions/workflows/test.yml/badge.svg)](https://github.com/pixta-dev/repository-mirroring-action/actions/workflows/test.yml)
 4 | 
 5 | A GitHub Action for mirroring a repository to another repository on GitHub, GitLab, BitBucket, AWS CodeCommit, etc.
 6 | 
 7 | This will copy all commits, branches and tags.
 8 | 
 9 | >⚠️ Note that the other settings will not be copied. Please check which branch is 'default branch' after the first mirroring.
10 | 
11 | ## Usage
12 | 
13 | 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.
14 | 
15 | To find out how to create and add the `GITLAB_SSH_PRIVATE_KEY`, follow the steps below:
16 | 1. [How to generate an SSH key pair](https://docs.gitlab.com/ee/ssh/#generate-an-ssh-key-pair). Recommended encryption would be _at least_ `2048-bit RSA`.
17 | 2. Add the _public_ key to [your gitlab account](https://gitlab.com/-/profile/keys)
18 | 3. Add the _private_ key as a secret to your workflow. More information on [creating and using secrets](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/creating-and-using-encrypted-secrets).
