If your Caddyfile works, then you can simply use the caddy adapt command to get the underlying JSON config for it.

Thank you francis,
i didn’t know there was an adapter, it’s very useful.
I leave the command example below for those who don’t know likeme
thanks again

caddy adapt --config /etc/caddy/Caddyfile --pretty

[francislavoie]

Yep! The Caddyfile itself is an adapter to JSON. It’s just some syntax sugar to make using Caddy easier, but Caddy always uses JSON under the hood.
