Why shouldn't I run multiple processes in a Docker container?

I've been told you should only run a single process within a container. Why can't I run more than one? It looks like I can use supervisord to do this.

You can use Supervisord or Honcho to build multiple processes container.

Personally, I don't think processes generally map well to separation of concerns in a one-to-one fashion.

In fact, I think the best reasoning for recommending running only one process per container today is technical and boils down to process management and logging issues for the most part. These aspects tend to get messy and complicated when you have more than on process in a container.

Because of separation of concerns pattern. It will be easy to upgrade or modify separate containers running separate processes.
