I always thought of containers as essentially a universal linux package manager. If you ever yum install something and see it pull in dependencies, it's not like there's an elegant software solution that makes that happen; it's work done by people who maintain lists of what each package requires and compatible versions. Red Hat puts considerable effort into that, and it's work duplicated by other distros, each with their own packaging idiosyncrasies.
