Maybe I'm being obtuse, but doesn't using a configuration management tool to deploy black-box Docker containers eliminate many of the advantages of using config management in the first place?
So you’re asking why not simply use Ansible to deploy all this software? Because that would be anything but simple and would negate almost all the benefits of docker like easy updates and immutability. This is the best of both worlds in my opinion. Ansible handles deploying the configuration that docker then uses.
Additionally the plan is to move to Kubernetes soon for multiple node deployment, and that wouldn’t really be possible without Docker.
And to be clear, some software is installed directly by Ansible, where it makes sense to do so.
