A GitHub Action for mirroring a git repository to another location via SSH.
Required SSH URL of the source repo.
Required SSH URL of the destination repo.
Optional (default: false) Execute a dry run. All steps are executed, but no updates are pushed to the destination repo.
SSH_PRIVATE_KEY: Create a SSH key without a passphrase which has access to both repositories. On GitHub you can add the public key as a deploy key to the repository. GitLab has also deploy keys with write access and for any other services you may have to add the public key to your personal account.
Store the private key as an encrypted secret and use it in your workflow as seen in the example workflow below.
SSH_KNOWN_HOSTS: Known hosts as used in the known_hosts file. StrictHostKeyChecking is disabled in case the variable isn't available.
If you added the private key or known hosts in an environment make sure to reference the environment name in your workflow otherwise the secret is not passed to the workflow.
