Hi,

I have a docker compose file that is starting up a nodejs app and NPM

version: "3.8"
services:
  node-app:
    build:
      context: .
    env_file:
      - .env
    command: npm run start
    restart: unless-stopped

  nginx:
    image: 'jc21/nginx-proxy-manager:latest'
    restart: unless-stopped
    ports:
      - "80:80"
      - "443:443"
      - "81:81"
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt

I have pointed my subdomain to my vps's IP and abc.mydomain.com does point to the "Congratulations page" of NPM.
I dont believe `node-app` needs the port exposed according to https://youtu.be/P3imFC7GSr0?t=441 (the video says that the port doesnt need to be exposed and that the docker network will have access to the `node-app`. My node app is running on port 8000

Currently:

- `123.456.789.123` points to the "Congratulations page"

- `123.456.789.123:81` points NPM login page

- `abc.mydomain.com` points to the "Congratulations page"

- `abc.mydomain.com:81` doesnt do anything

How do i make it so that

- `abc.mydomain.com` points to the node-app

- `def.mydomain.com` points to NPM login page.

- `123.456.789.123` points nothing

- `123.456.789.123:81` points to nothing

​

When I used the internal IP (for example 172.22.0.2) of the node-app as a proxy host, it did work, however, everytime I redeploy my container, it breaks because the internal IP changes
