Postgres connection failure

Thanks for this Enis, but there appears to be an error when the build attempts to do the migrations:

Another student here has had similar problems with postgres and ended up running postrgres in a different container. I'll give that a shot.

Hmm, I didn’t think stuff like this is supposed to be happening with Docker... The image builds fine on my machine. I pushed it to Docker Hub so feel free to try that one: https://registry.hub.docker.com/u/afgane/cloudlaunch/

Reusing a docker potgres image and hooking this up with fig for example would be a nicer way of going about it but until it's demonstrated as useful, I didn't feel like getting into all of that. In other words, if you guys manage to set it up better, please consider issuing a pull request with the enhancements.

Have just come back to this and successfully launched the container on OSX 10.10.5.

Note that boot2docker is deprecated in the most recent version of Docker. Instead of $ boot2docker ssh -vnNTL 8000:localhost:8000, in a separate tab I ran $ ssh docker@$(docker-machine ip default) -L 8000:localhost:8000 and was able to reach the application.

This issue can be closed though.
