I use Docker Compose for running all the things for my dev environment (RabbitMQ, Postgres, a few others), and it works really well. We'll, now it does - I had no end of networking troubles with it in the past, on both Linux and Windows.

I love how easy it is to spin up something new with a simple YAML file, but I've no idea what it would be like in production - how are rolling updates handled, for example?
