Reproduction steps

Hello, when I try to change caddy port to something else from 80 (already used on my system) I can't access to setup.

Docker compose file:

services:
  pocket-id:
    image: stonith404/pocket-id  # or ghcr.io/stonith404/pocket-id
    restart: unless-stopped
    env_file: .env
    ports:
      - 3000:81
    volumes:
      - "./data:/app/backend/data"

.env file:

PUBLIC_APP_URL=https://auth.domain.com
TRUST_PROXY=true
MAXMIND_LICENSE_KEY=
PUID=1000
PGID=100
CADDY_PORT=81

docker ps

$sudo docker ps | grep pocket

Successfully started Caddy (pid=38) - Caddy is running in the background
Listening on 0.0.0.0:3000

Expected behavior

Access to Pocked-ID through port 81

Actual Behavior

I can access to frontent on host:3000 but host:81 or host:80 give nothing.

You're exposing port 3000 so it's accessible only on this port. CADDY_PORT is just inside the container.

Try to keep CADDY_PORTon 80 and change the exposed ports to 7467:80. It should then listen on port 7467.

Thanks @stonith404, I've revert to CADDY_PORT on 80, and only change expose port to 3001:80 and it's working much better !

I think I was misdirected by Environnement variables section of the docs where it's indicated If you want to change the exposed port of the container then you sould change this variable. for CADDY_PORT
