Slight clarification, this isn't new in Docker, you're describing "Immutable Systems". It's also not mutually exclusive with configuration management tools. The systems management tools have been doing this a long time with baked cloud images, most prominently Packer invoking configuration-tools-of-choice for baking cloud images straight (which I'd say STILL has a wider adoption than Docker) and this can also be done inside Docker files, just like it can be done for AWS image baking. You're still going to have some things that need to be done in runtime, especially in managing your stateful servers.
