List images
-a, --all=false: Show all images (by default filter out the intermediate images used to build)
-a, --all=false: Show all images (by default filter out the intermediate image layers)
--no-trunc=false: Don't truncate output
-q, --quiet=false: Only show numeric IDs
The default ``docker images`` will show all top level images, their repository
and tags, and their virtual size.
Docker images have intermediate layers that increase reuseability, decrease
disk usage, and speed up ``docker build`` by allowing each step to be cached.
These intermediate layers are not shown by default.
