Current master branch is missing a Gem (rkelly) so this is added to the Gemfile during the image build.
The default login for the WarVox web interface is admin/godsexlove ;-)
Pull the standard postgres image
docker pull postgres
Start the image in the background
docker run -d --name=postgres postgres
Run the warvox container, linking the progres container and opening up port 7777.
docker run -d -p 7777:7777 -ti --link postgres:db sans1241/warvox
Now connect to port http://127.0.0.1:7777
