This will account for settings that are provided by the hierarchy of
Dockerfiles used to construct your image, rather than only accounting
for settings provided to the module directly.
Organize each state into a distinct function for readability and composability.
Rework `present` to create but not start containers. Add a `restarted` state
to unconditionally restart a container and a `reloaded` state to restart a
container if and only if its configuration is incorrect. Store our most recent
knowledge about container states in a ContainerSet object. Improve the value
registered by this task to include not only the inspect data from any changed
containers, but also action counters in their native form, a summary message
for all actions taken, and a `reload_reasons` key to store a human-readable
diagnostic to determine why each container was reloaded.
This allows setting the pid namespace for a container. Currently only
the 'host' pid namespace is supported.
This requires Docker 1.4.1 and docker-py 1.0.0
Don't pass the volumes_from argument to the Docker create_container method.
If the volumes_from argument is passed to the create_container method, Docker
raises the following exception:
docker.errors.DockerException: 'volumes_from' parameter has no effect on
create_container(). It has been moved to start()
If bind-volumes are submitted to docker >= 1.4.0 with the volumes set in addition to the binds, docker will create a regular volume and not bind-mount the specified path.
Starting from docker-py>=0.5.0 it is impossible to work with private registries based on HTTP.
So we need additional parameter to allow pull from insecure registry
