Feature: Define domains for caddy and add them to /etc/hosts

[jochenmanz]

Describe the Feature
It would be great to be able to use domain names as virtual hosts in caddy. Devenv could handle the /etc/hosts changes (or dnsmasq configuration).

• modules: introduce hostctl (static dns for development) numtide/devshell#75
• modules: introduce mkcert (development certification authority) numtide/devshell#74

@blaggacao do you want to make a PR to devenv if you are already familar with that

[domenkozar]

We need a solution that works for macOS and linux and ideally is scoped to the environment.

[domenkozar]

Yes please: https://guumaster.github.io/hostctl/docs/guides/basic_profiles/

It has been literally years. And we're not using devenv (yet). But considering. Since divnix/std is deeply integrated with numtide/devshell switching isn't going to be cheap or straightforward, either.

Iirc, during all the time past there where also ideas about a HOSTFILE variable to define project hosts files.

It might be at least worth it to do a quick research to see where these ideas are currently at (and if they have sufficiently progressed).

I guess this would require some kind of pre- and post-scripts to devenv up to be able to execute the hostctl 🤔

A draft implementation of an opt-in shared HTTP proxy is now available in #3141. It derives .localhost URLs from devenv project/process names, so these local virtual hosts do not require /etc/hosts changes or dnsmasq. The current scope is HTTP-only and does not provide arbitrary domains or Caddy-managed HTTPS.
