a dockerfile to play githug without installing anything
githug[https://github.com/Gazler/githug] is a nice ruby project that everyone who wants to learn Git should know and use.
With it you can learn Git by solving a series of levels of increasing difficulty.
This simple dockerfile lets you play githug without having to install ruby and other dependencies on your system.
The use is straightforward: clone the repo, start docker and you are done
git clone https://github.com/pomarc/githug-docker
cd githug-docker/
docker build -t githug-docker-image .
docker run -ti --name githug githug-docker-image /bin/bash
and you are in a githug environment.
you simply type
githug
at the prompt and start playing. ta-da.
If you feel like exiting, type exit: the docker container will exit, but your levels are saved in a docker volume.
When you want to continue your learning, just restart the same container with
docker start -i githug
and you are on your session again, with your progress saved.
Easy peasy.
