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


SYNOPSIS
       docker system info [OPTIONS]


DESCRIPTION
       This  command  displays system wide information regarding the Docker installation.  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 details 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

       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:
