       docker-system-info - Display system-wide information

       docker system info [OPTIONS]

       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 de‐
       scribes 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:
