Port baked into PULLPREVIEW_URL causing issues

[geoffatsource]

I'd like to be able to set up Caddy to serve from two different ports but since the port is baked into the env variable it's causing issues. Is there a way around this?

I will try changing my Caddyfile to use path matchers instead

{$PULLPREVIEW_URL} {
  handle_path /* {
    reverse_proxy http://client:3000
  }
  handle_path /api/* {
    reverse_proxy http://api:8080
  }
}

I know this is a Caddy thing but I'm not able to get this to work with the path matchers under one port. I think we need a way to get the PULLPREVIEW_URL without the port

I got it to work with the above configuration and this docker-compose snippet:

  # Caddy for SSL termination
  # ----------------
  web-proxy:
    image: caddy:2
    restart: unless-stopped
    environment:
      PULLPREVIEW_URL: ${PULLPREVIEW_URL}
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - $PWD/Caddyfile:/etc/caddy/Caddyfile
      - caddy_data:/data
      - caddy_config:/config

I'd recommend testing this out and adding it to your docs

Hello, if you only want the host, have you tried using PULLPREVIEW_PUBLIC_DNS? And building URLs around it if needed?

I may try that in the future, but I got it working better using a single port and path matchers.... a lot cleaner. Thanks!
