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.

       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:
