impossible to test idempotency of a role

[marcomc]

re-running the test that makes use of provision_docker would recreate a docker container making impossible to test idempotency of a role (or set of roles) over the same container
I have tried to set the item's restart attribute to false from the inventory, host_vars file and event as vars in the same playbook but the container would always be rebuilt (with a new Container ID) every time the "Bring up inventory group of hosts" task is executed

[marcomc]

what actually triggers the recreation of the container indiscriminately is the attribute network_mode if set to none it will not rebuild the container...but makes the test useless because you cannot install external componets on it (apt or yum packages for instance)

Maybe a state: present term would be useful since you could then re-run and check idempotency of a role, or connect to an already present docker container. Making this module potentially usable for creating docker infrastructure and provisioning it for mimicing production environments in docker for development.
