Testing Dockerfile

[minimalparts]

Yeah for the deployment scripts!! I don't know whether this is ready to be played with already, but I thought I would, through sheer impatience :P A couple of issues for me with setting things up:

• I need to run docker through sudo (perhaps add to README?)
• I had to change FROM debian to FROM ubuntu for my setup
• for whichever reason, wget failed the first time for me and I had to re-run the build -- perhaps add a retry to wget? What do you think?
• for docker noobs like me, say that the app is running at localhost:9000...
