NAME
       docker-system-info - Display system-wide information

SYNOPSIS
       docker system info [OPTIONS]

DESCRIPTION
       This  command displays system wide information regarding the Docker in-
       stallation.  Information displayed includes the kernel version,  number
       of  containers and images.  The number of images shown is the number of
       unique images. The same image tagged under different names  is  counted
       only once.

       If  a  format is specified, the given template will be executed instead
       of the default format. Go's text/template package describes all the de-
       tails of the format.

       Depending  on  the storage driver in use, additional information can be
       shown, such as pool name, data file, metadata file,  data  space  used,
       total data space, metadata space used, and total metadata space.

       The  data  file is where the images are stored and the metadata file is
       where the meta data regarding those images are stored. When run for the
       first  time  Docker  allocates  a certain amount of data space and meta
       data space from the space available on the volume where /var/lib/docker
       is mounted.

EXAMPLES
Display Docker system information
       The  example  below  shows  the  output  for a daemon running on Ubuntu
       Linux, using the overlay2 storage driver. As can be seen in the output,
       additional information about the overlay2 storage driver is shown:
