I have a Mac Pro 2012 (OS X 10.11) which I'm using as a server, set up with Docker for OS X and the official gitlab CI runner installed according to https://docs.gitlab.com/runner/install/osx.html.
That works fine, except one thing: I have to log in and stay logged in with my own user account every time after a reboot so that Docker and the gitlab runner actually run.
How do I get both Docker and the gitlab CI runner running independently of any user being logged in?
