Does it? Or, rather, is it even simpler?

To host something as a docker container I need 2 things: to know how to host docker, and a docker image. In fact, not even an image, just a dockerfile/docker-composer.yaml in my source code. If I need to host 1000 apps as a docker containers, I need 1000 dockerfiles and still to know (and remember) 1 thing: how to host docker. That's 1 piece of knowledge I need to keep in my head, and 1000 I keep on a hard-drive, most of the time not even caring what's the instruction inside of them.

If I need to host 1000 apps without dockerfiles, I need to keep 1000 pieces of knowledge in my head. thttpd here, nginx to java server there, very simple and obvious postgres+redis+elastic+elixir stack for another app… Yeah, sounds fun.
