Well, more than that, it's packaging them into user-friendly tools and promoting the shit out of it.

Still Docker the company's core value proposition is a hosted registry, something many savvy corporations will never go for. Docker the product could probably do just fine if the company were to fold.

but the hosted registry is what your average distribution already provide under the form of packages.

and with everything moving to services, I see the utility of actually using components diminishing fast (well except for those providing those services)

but for everyone else, docker solves no actual problem that can't already be solved now.

Writing a Dockerfile and typing "docker run whatever" is a hell of a lot easier than configuring a chroot and LXC container.
