I just like the philosophy of docker, although I am recognizing here the implementation has some warts.
also, if you're just a user of docker you might not care about dockerfiles. (like most people building software don't care about the Makefiles and prefer not to look at them)
I like some of the philosophy of docker. But there are improvements left on the table around build and shipment efficiency. Plus it introduces real problems at scale, mostly around the sanity and safety of the overall cluster.
