Trying to setup Traefik with duckdns Gateway error

Expected Behaviour

Get working CVAT

Current Behaviour

Not working CVAT -> Bad Gateway

Possible Solution

A proper configuration

Steps to Reproduce (for bugs)

1. git clone https://github.com/opencv/cvat
2. cd cvat
3. docker-compose build
4. docker-compose.override.yml

version: '3.3'

services:
  cvat_proxy:
    environment:
      CVAT_HOST: cvat.example.duckdns.org

5. docker-compose.yml (modified following)

# --- Removed networks section and put that ---
networks:
  web:
    external: true
  internal:
    external: false

# --- Under cvat-proxy: ---
ports:
      - '3750:80'
labels:
      - traefik.http.routers.cvat.rule=Host(`cvat.example.duckdns.org`)
      - traefik.http.routers.cvat.tls=true
      - traefik.http.routers.cvat.tls.certresolver=lets-encrypt
      - traefik.port=3750
networks:
      - internal
      - web

# -- Modified all services -> cvat_db, cvat_redis... networks to  (maybe this is wrong, removing aliases) --
networks:
      - internal
      - web

6. docker-compose -f docker-compose.yml -f components/analytics/docker-compose.analytics.yml -f docker-compose.override.yml up -d --build

I think that may be related with networks, if I could add internal and web to the default one you specified with the aliases 'ui' and so on

I followed this guide to setup traefik -> https://www.digitalocean.com/community/tutorials/how-to-use-traefik-v2-as-a-reverse-proxy-for-docker-containers-on-ubuntu-20-04#step-3-%E2%80%94-registering-containers-with-traefik

If I set my public address to CVAT_HOST I can access through the public IP

[MarioProjects]

Solution: Traefik is not needed for that?! With next at docker-compose.override.yml file I am able to access cvat.myname.duckdns.org:3710.

version: '3.3'

services:
  cvat_proxy:
    environment:
      CVAT_HOST: cvat.myname.duckdns.org
    ports:
      - '3710:80'
    volumes:
      - ./letsencrypt-webroot:/var/tmp/letsencrypt-webroot
      - /root/.acme.sh:/root/.acme.sh

  cvat:
    environment:
      ALLOWED_HOSTS: '*'

Last question is, If I wont use 3710, only host name, if I set ports 80:80 it says ERROR: for cvat_proxy Cannot start service cvat_proxy: driver failed programming external connectivity on endpoint cvat_proxy (6bd422d9878e2861467ff18715bc99669e05aabaea7221ea6d9923b34744cd15): Bind for 0.0.0.0:80 failed: port is already allocated
