Mirror repository from Gitlab to Github using Gitlab CI and ssh (Github deploy key)
Inspired by: https://gitlab.com/t-munk/gipsy
This project uses ssh Github repository deploy key instead of Github user access token.
Repository deploy key enables access to single repository.
User access token enables access to all user repositories.
Add the following environment variables to the GitLab repository you want to push to GitHub:
GITHUB_DEPLOY_KEY (generate a new key using ssh-keygen)
GITHUB_REPO (myuser/the-repo)
See .gitlab-ci.yml mirror task for an example, add this mirror stage your GitLab repository.
Push a commit to eg. the master branch of your GitLab repository.
