Docker-listener get all events from the Docker daemon using remote API over HTTP endpoint.
Most of the events are getting enhanced with container inspect information docker inspect and published to RabbitMQ. Events from Docker-listener later processed by API, Sauron and other systems.
Docker-listener deployed as container to the dock-services box.
