How I set up Kolab 3.2 in a Docker container

I see that you have referenced my initial attempts from your README.md. 
That makes me happy :)

I only did it as an experiment. My initial goal was to make it easy for 
people to get started to try out Kolab, and avoiding problems during the 
installation by making it automated and using the exact same 
reproducable environment.

Of course, for production use, it is something completely different. 
Therefore it makes sense that you have to run setup-kolab manually in 
your docker container once.

Another issue to look at, which is a problem in both our attempts:
I was reading about data persistence: to store the data not inside the 
container, and therefore making the container replacable. It seems to 
store the data inside the container is not the docker way of doing 
things. See also this thread:

See http://www.alexecollins.com/content/docker-persistence/
and https://docs.docker.com/userguide/dockervolumes/

I am currently not working on anything docker related.

All the best,
   Timotheus
