Caddy touble in Docker (lemmy.zip)

Howdy! Sorry if this is a supid question. I've been trying to get this working for like 5 days and I've been researching and reading docs, but I'm just not getting it. I'm fairly new to selfhosing and I'm trying to set up Jellyfin remote access on my NAS. My NAS is a QNAP product running QTS (which I absolutely hate). QTS uses their own weird version of Docker.

When I start Caddy with a docker compose file, I get an error that port 443 is in use and the container can't be started. If I create a container in the Container Station app directly from the Docker Image, it starts up fine. Container Station handles environment variables in a dumb way so I am having trouble specifying the Caddyfile location when I do it that way.

Does anyone know why it works fine in that way but not the other? Both use port 443 but when I do it in a docker compose file, it says the port is in use but when I do it the other way, it doesn't and starts fine.

Note: I know you can do this with Tailscale also, but I want to use my custom domain to make it easier for sharing in the future.

When I start Caddy with a docker compose file,

So, I've never owned a QNAP product running QTS nor have I run Caddy in a Docker container before, but I am assuming it looks something similar to this:

spoiler

networks:
  proxy-network:
    external: true

services:
  caddy:
    image: caddy
    container_name: caddy
    restart: unless-stopped
    ports:
      - 80:80
      - 443:443
    volumes:
      - ./data:/data
      - ./config:/config
      - ./Caddyfile:/etc/caddy/Caddyfile:ro
    networks:
      - proxy-network

Have you tried changing the port #:

    ports:
      - 80:80
      - 4443:443

Welcome to the club bro. You're in the right place.

Yeah, I can do that. I just wanted to understand why it work sometimes but not others.

I HATE QTS. It’s all proprietary software and it’s locked down so I can’t use CLI at all unless I SSH into it. And when I do that, I still can’t add 3rd party software that isn’t in their App Store because there is no apt, dnf, brew, or other similar tools.

I’ve been considering trying to install TrueNAS or something else on it but it sounds like that will be a hassle too because the fans don’t want to work.

That doesn't seem right... I think you can use their "Container Station" to make an LXD or Docker container with whatever you want. You may have to enable "advanced mode." https://www.qnap.com/en-us/how-to/tutorial/article/how-to-use-container-station-3
