Allow users to diff between two docker images|container. There
are two types of diffs that can be run -- a file diff or an
RPM diff. The file diff is always the default. The RPM diff
can be added with -r. The file diff can be excluded with -n.

NAME
atomic-diff - show the differences between two images|containers RPMs
SYNOPSIS
atomic diff [-h|--help] [--json] [--names-only] [-n][--no-files] [-r][--rpms] [-v][--verbose] image|container image|container ...]
DESCRIPTION
atomic diff will compare the RPMs found in two different images or containers and output to stdout or as JSON. By default, the comparison is done by name and version of the RPMs.
OPTIONS
-h --help Print usage statement.
--json Output in the form of JSON.
-n --no-files Instead of comparing the differences in name and version, it will only compare the difference in name. This will also change the output to only output the names.
--names-only Only show the RPM names and not versions.
-r --rpms Show the where the two docker objects have different RPMs.
-v --verbose Be verbose in showing the differences in RPMs. The default will only show the differences in RPMs, whereas with verbose it will show all the RPMS in each object.
EXAMPLES
Compare images the files in 'foo1' and 'foo2'.
atomic diff foo1 foo2
Compare the files in images 'foo1' and 'foo2' and output in JSON.
atomic diff --json foo1 foo2
Compare only the RPMs in images 'foo1' and 'foo2'
atomic diff -r -n foo1 foo2
Compare the files and RPMs (without versions) in images 'foo1' and 'foo2' and output as json
atomic diff -r --json foo1 foo2
