An article by Seulkiro Park in which he sheds the light on deployment process utilizing continuous integration and continuous delivery (CI/CD) tools offered by GitLab.
In the tutorial he guides you through:

GitLab has a runner to manage jobs as part of CI/CD, e.g. test, deploying to staging or production environments. You can navigate to Settings > CI/CD > Secret Variables and then you can store your secret keys or any other environment variables that the Runner can access to.
