Unfortunately that’s one area I am bad with, I tend to use reverse_proxy for most such as Baikal running with the ckulka/baikal Docker image (which runs Nginx or Apache), otherwise I only static sites.
I’d start by looking at Baikal’s config for Apache and Nginx, https://sabre.io/baikal/install/ and comparing to the directives for Caddy, https://caddyserver.com/docs/caddyfile/directives and
Since it uses PHP, it will need that, https://caddyserver.com/docs/caddyfile/patterns#php
Upon my searches I came across this, it talks about running Baikal with Caddy specifically. https://github.com/caddyserver/caddy/issues/497
I hope that this provided some helpful directions.
Looks like someone asked Ethan about posting to Lemmy, and they replied “Thanks for sharing – adding it to the list of places to post!”.
