For various reasons Docker is oriented towards
one-process-per-container. Fortunately, GenieACS actually lends itself
quite well to that approach, though startup ordering bears some
consideration.

Docker Compose (which Guillaume has used) lets you "orchestrate" a
collection of Docker containers. If you were using something like
Kubernetes or Mesos or something like that then they'll typically have
their own mechanisms for orchestration, but this all still basically
works well if you have one thing per container and tends to suck a bit
if you have more than one thing per container, since now failures and
monitoring apply to a blob with stuff in rather than a single process.
