Add script and extra instructions for docker users

[finkdiff]

With the shift of BrewPi to a docker setup could you add the instructions for integrating this using a container and add a script for copying the files within the container and fixing the permissions afterwards as it would make it a lot easier for those who do not use Bash much?

Essentially it boils down to creating the container using an extra flag as below (assuming WiFi):

sudo docker run -d --privileged --net=host --name brewpitilt -p 80:80 -v ~/brewpitilt-data:/data -v /etc/timezone:/etc/timezone -v /etc/localtime:/etc/localtime --restart always brewpi/brewpi-raspbian

Running apt-get update and then upgrade

Following your 'read me' instructions but ensuring that they are done in the terminal on the container. This last part would be much easier if the copying of the files and fixing permissions could just be done by running a script by the end user.

I'm just getting going. I tried your command, but I've hardly used docker. How do you run the instructions "in the terminal on the container"? I'm using my mac to ssh into the pi and I can see brewpi running in Portainer and on the local web. When I run the above command it's running brewpi-tilt.

I can run the test script in python on the pi and it works so it can connect to it, but I'm guessing it's not working in BrewPi because I've not run those commands in the docker container?
