It depends on how you are using containers. If you control what code is run in them and who has access to the containers and their hosts, then production use should be fine as far as security goes.

However, if you're trying to run something which lets untrusted people login to the containers or run arbitrary untrusted code in the containers, then I certainly wouldn't recommend doing that with containers in a production environment.

One project you might like to keep an eye on is CoreOS [1]. As I understand it, their goal is to create an OS which will come configured to safely run containers. Once it is ready I would expect it will be suitable for use in a production environment.
