command: docker system info
short: Display system-wide information
long: "This command displays system wide information regarding the Docker installation.\nInformation
  displayed includes the kernel version, number of containers and images.\nThe number
  of images shown is the number of unique images. The same image tagged\nunder different
  names is counted only once.\n\nIf a format is specified, the given template will
  be executed instead of the\ndefault format. Go's **text/template** package\ndescribes
  all the details of the format.\n\nDepending on the storage driver in use, additional
  information can be shown, such\nas pool name, data file, metadata file, data space
  used, total data space, metadata\nspace used, and total metadata space.\n\nThe data
  file is where the images are stored and the metadata file is where the\nmeta data
  regarding those images are stored. When run for the first time Docker\nallocates
  a certain amount of data space and meta data space from the space\navailable on
  the volume where `/var/lib/docker` is mounted.\n\n# EXAMPLES\n\n## Display Docker
