I think one thing to keep in mind about Ansible is that it's an orchestration tool that also does configuration management. We've integrated Ansible into our workflows in such a way that it kicks off everything we need to do, even if that involves just coordinating some info between APIs. We don't mutate containers at all - merely get Ansible to make things happen around their deployment and communication.

How do you use ansible to deploy your containers, if I may ask ? We're looking into the docker module right now, but I don't know if it's good or what. Currently we're launching container via systemd and manage the unit files with ansible.

We're running all the containers on Mesos hosts, so really all Ansible needs to do for us is talk to Marathon. We realized early on down this path that to accommodate scale we'd need to have some sort of scheduler. Mesos happened to be the most robust.

We originally tried the docker module in Ansible but found it had a few problems. There's been a lot of work on it since, and I expect it will be in a much better state when Ansible 2.0 is released.
