At Shippable(shippable.com) we've been using docker for over an year now for the following use cases:

1. deploying all our internal components like db, message queue, middleware and frontend using containers and using a custom service discovery manager. The containerization has helped us easily deploy components separately, quickly set up dev environments, test production bugs more realistically and obviously, scale up very quickly.

2. running all the builds in custom user containers. This helps us ensure security and data isolation.

We did run into a bunch of issues till docker was "production-ready" but the use case was strong enough for us to go ahead with it
