Quick and dirty basic image for MEAT:
"MEAT is meant to be displayed outside your meeting rooms on any device with a modern web browser (we use iPads, but you can use netbooks, phones, or whatever). If you're signed up with Google Apps, MEAT will display status for all your meeting rooms and allow you to book time on the spot."
docker run -it -p 8888:80 -p 60053:60053 macadmins/meatlocker
Copy and paste the https://www.googleapis.com/auth/calendar URL that is displayed to grant MEAT access to calendars you manage. The callback URL points to localhost, you may have to manually change this to the IP of the Docker container and reload, it should register with MEAT.
Now hit http://<host or ip>:8888/
Change configuration: run Docker with a volume-mounted core.js file from the Docker host to pick up changes from there:
docker run -it -p 8888:80 -p 60053:60053 -v /local/path/core.js:/meat-data/config/core.js macadmins/meatlocker
