Docker's production ready. It's stable (in the sense that it doesn't crash) reliable software. People have been using it production for a long time, and really it's just a wrapper around Linux containers, which people have been using in production for even longer.

Docker's not production ready. The APIs aren't locked down and the developers haven't said it is production ready yet. It may be possible to break out of the container (if you expect to use it like a VM) and people are still fighting over if you should "Dockerize" at the application, service or executable level.
