This Docker image is used at Decemberborn Interactive to automate builds and running unit tests for Cathedral in our CI environment.
We initially used https://github.com/andystanton/docker-gcc-cmake-gl as a base, but decided to create our own version instead of updating/installing packages such as a newer CMake on each build. This significantly reduces our CI build times.
The main technologies used are gcc 4.9, boost 1.57, CMake 3.3,
Python 2.7. We also install Pillow that we use for texture loading
in prebuild steps.
The image is very specific to our use-case, but hopefully someone else might find it useful too.
