Advices and remarks

• Take care of integrity of your files: use :ro when mouting volumes, no reason for ansible to write anything.

• Ansible has no real context over 2 subsequent executions, so it can be reinstantiated each time. That's why containerize it and passing --rm it's not a problem.

• If you plan to use Docker on the local instance, you will probably face a problem. Look at jpetazzo/dind first.

• Remark : this image is shipped with pip and docker-py (See here for the features it enable)
