Containerization is only heavy outside of Linux, and orchestration only makes sense when manual orchestration becomes too tedious (it’s easy to orchestrate a single app).

Keeping docs for those things is very troublesome imo. You can’t feasibly consider everyone’s different environment, C library used, their system’s package manager and how it may package software differently than yours, and the endless array of things they may have already installed that may effect your app in some way. Sure, it’s not super common, but it’s hell when it does.

But I suppose if your use case is very simple, like “just have nodejs installed and run npm start” then sure. But things can get ugly very easily.
