A simple container to have a freeciv server up and running.
Build uppon debian/jessie-slim, it exposes port 53773.
And of course, it uses the version available in the repositories, which is 2.4.
Maybe i'll give the 2.5 a try sometime... ;)
So, to start simply use
docker run -d -p <ip>:<port>:53773 cbkffhef/docker-freeciv:latest
and you should be ready to go.
