How do I set hostname in docker-compose?

Question

In my docker-compose.yml file, I have the following. However the container does not pick up the hostname value. Any ideas?

dns:
  image: phensle

This issue is still open here: https://github.com/docker/compose/issues/2925

You can set hostname but it is not reachable from other containers. So it is mostly useless.
