I'm sympathetic to the cause, but this example would not serve well a noob trying to dive into the subject. * It does not work (bug in node Dockerfile) * It requires extra builds (while users expect `docker-compose up` to _just work_) * There's no tester container to curl something to ensure me it works * The docker files are half baked - ex. not using layers correctly (npm install called after code COPY), ex. `npm build` redundantly called, ex. using ubuntu:latest rather than golang:onbuild... and so on. And yes, I guess I could fix all that... submit a PR, and be declared the king of HN. But today I rather just complain.
