Add custom config Caddy to the static binary

[JuanLuisGarciaBorrego]

Hello franken's!

Is it possible to the configure caddyfile in static binary?
For example, change custom port:
:{custom_port}{
...rest config
}

I have seen that it is possible to add extensions in this issue

What I'm trying to do is:
I have a server with traditional caddy setup for my frontend application.

When I try to run the binary
sudo ./my-app php-server --domain api.domain.com

get error:
Error: loading new config: http app module: start: listening on :443: listen tcp :443: bind: address already in use

Any ideas /alternative?

Thanks!!

I think you can just add a Caddyfile to the root of your project and it will be used by default when running ./my-app php-server
