Did you try Dokku[1] (git hook + Heroku buildpacks + Docker)? You can build/deploy several apps to docker containers using git push. It has PostgreSQL plugin and exposes your app via nginx. Of course it wouldn't be 100% usable as-is, but its codebase is very hackable — around 150LOC.

For example I've forked it to built a μPaaS[2] — it has out-of-the-box integration with upstart (for supervision and logging) and replaced Heroku buildpacks with the ability to define stack in Dockerfile (which is much simpler).

The only reason I haven't tried it is because I've never really used Heroku, but I'll give it a shot now, thanks.
