I believe a similar Dockerfile based on heroku would be useful to deploy using their procedure for docker apps.
Otherwise we have individual projects like so
That said we can deploy raw bins built with a compatible system
Agree with @adinapoli. A Dockerfile will help port it to other base images as well. E.g. I'd like to work with cloud foundry compatible image.
I would like to play with this a bit (namely to bootstrap this from a CentOS 6 base image). Is the original Dockerfile proprietary or it can be shared?
