 To view your stats, open a web browser and visit http://localhost:8080 (replace localhost with your docker host's hostname or ip address).
 
 Mounting the volumes /var/lib/docker and /var/run/docker.sock (read-only) is required so that the docker container can retrieve the statistics for the containers.
