Title: Security patch: bind port 5432 to docker0 interface

Avoids opening the db port to the outside world (0.0.0.0) by specifying the IP address of the docker0 gateway interface when launching the new container.

By binding to docker0, the db port can only be accessed by other containers on docker's subnet.
