This is a work in progress, but the goal is to simply have a pre-configured emscripten environment ready to go. I will attempt to minimize the image size but with this type of project and requirements I don't think I will be terribly successful.
I am using the Alpine Linux 3.7 image as a base, this in its self has produced some challenges, but hopefully the end result will be worth the effort.
Building this container can be very time consuming
docker run -i -t --name emscripten jamesbrink/emscrpten
