Docker use Dockerfile (ini) to create container images, so you need to create a soup of Dockerfile, bash scripts combine it with ansible scripts. So it is kind of incompatible, it's better to use LXD containers as I suggested in my previous post for this kind of purpose. Also if you know Docker always maintained one process one docker container so a multi-daemon system with SSH and various mail and groupware servers running is not right choice for Docker. Using docker for such things is like putting a square peg in a small round hole.
