* Automatic Dockerfile update by release process

We've seen multiple users thinking that simple creation of two containers
is enough, whereas this isn't the case: at the very least, the deprecated
`--link` docker option must be used, but more compliant is the use of
custom networks and bridges. Docker-compose sets all that up automatically,
so don't suggest going without docker-compose is simpler.
