Ubuntu 12.04 appears not to work right about docker-brew-ubuntu-core

You'll want to check out the "Ubuntu Core" project for more information
about our base images. Generally, we always go for smaller since most
people don't need things like "sudo" in a Docker container anyhow.

(and if they do, it's a simple "apt-get install" away)

Hi,

Thank you for the reply. I notice some things like just trying to start and stop services doesn't appear to work or give any sort of output. It works fine in ubuntu 14.04. Is it missing something regarding basic starting and stopping of services?

Do have a more specific set of steps I could follow to reproduce? A
Dockerfile would be especially great.

All I did was a docker pull didn't use a dockerfile or anything.

docker pull ubuntu:12.04
docker run -t -i ubuntu:12.04 /bin/bash

Try running any service related command. e.g. service network stop | start you get no output at all

That is by design. When you invoke service xyz start, it doesn't actually start the service - it talks to Upstart (which isn't running in your container), and then Upstart starts the service. In containers, we strive for one process per container, so Upstart doesn't run and we instead run just "apache" by itself, for example.
