This image is based on the slim version of the Debian jessie image. It provides the official Linux server 64-bit 2.1.2-stable build of Godot Engine along with the official templates.
The primary application is for automating Godot Engine builds.
Godot Engine is located at /bin/godot and the templates are installed in /root/.godot/templates.
The source repository contains a Vagrantfile who provides Docker and Gitlab Runner. It can be used to test your Gitlab CI configuration (see .gitlab-ci.yml in the source repository):
$ gitlab-runner exec docker <job name>
There is no need to register the runner first.
