Bare metal / VM install instructions

Is your feature request related to a problem? Please describe.

The world is not docker. There are use cases for it, but there are a lot of uses cases where docker is not the best solution. Just providing install instructions for docker leaves out those situations where something else than docker is required / needed / decided upon / forced, nginx runs on a lot of platforms, not only on docker. There may be unsupported architectures in use (risc-v, cheri, powerpc, …), there may be unsupported OS in use (*BSDs), there may be a requirement that it runs in a VM (no matter if because of policy, security reasons, or whatever), and so on… where your project would run simply fine. It also prevents an OS specific package management to pickup your project as an easy package install. There may also be a security requirement that the software bill of materials is easily inspectable and that open source stuff has to be manually fixable independently from the original developer, that no pre-build image from an unknown source is allowed to be installed.

The dockerfile is not an install instruction. You are locking yourself into a niche instead of opening yourself to the entire open source ecosystem.

Describe the solution you’d like

Provide bare metal install instructions (list of requirements, initial config, where to install what from your repo).
