    14  Information displayed includes the number of containers and images, pool name,
    15  data file, metadata file, data space used, total data space, metadata space used
    16  , total metadata space, execution driver, and the kernel version.
    17  
    18  The data file is where the images are stored and the metadata file is where the
    19  meta data regarding those images are stored. When run for the first time Docker
    20  allocates a certain amount of data space and meta data space from the space
    21  available on the volume where `/var/lib/docker` is mounted.
