Ansible author here (http://github.com/ansible/ansible http://github.com/ansible/ansible). My view on this, basically, is that the role of automation tools in the Docker realm is going to be exactly like it is with most of the people who like to 'treat cloud like cloud' -- i.e. immutable services. The config management tools -- whether Ansible, Puppet, Chef, Ansible, whatever -- are a great way to define the nature of your container and have a more efficient description of it. You'll also continue to use management software to set up the underlying environment. And you might use some to orchestrate controls on top, but the set of management services to manage docker at a wider scale are still growing in nature and very new. I'm keeping an eye on things like shipyard but expecting we'll see some more companies emerge in this space that provide management software on top. Is Docker right for everyone? Probably not. However I like how it is sort of (in a way) taking the lightweight vagrant style model and showing an avenue to which software developed in that way can be brought into production, and the filesystem stuff is pretty clever.
