This GitLab CI runner image allows to deploy a GitLab project to a remote Git repo (useful for Dokku, Heroku, Deis, etc.)

Create .gitlab-ci.yml:

image: ilyasemenov/gitlab-ci-git-push

stages:
  - deploy

deploy to production:
  stage: deploy
  environment: production
  only:
    - master
  script: git-push [email protected]:myapp

Go to GitLab > Project > Settings > CI/CD > Secret Variables, and add a variable SSH_PRIVATE_KEY:

-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----

By default, git-push will push to branch master of a remote repository (that's what Dokku wants). You can override this with:

git-push [email protected]:repo branch

git-push ssh://[email protected]:8022/myapp

By default, git push will be forced. You can disable force push by setting environment variable DISABLE_FORCE_PUSH to any value.
