The following example is known to work well with Traefik and docker-compose.

services:
  olivetin:
    container_name: olivetin
    image: jamesread/olivetin
    volumes:
      - /docker/olivetin:/config # replace host path or volume as needed
    ports:
      - "1337:1337"
    restart: unless-stopped
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.olivetin.entrypoints=web"
      - "traefik.http.routers.olivetin.rule=Host(`olivetin.example.com`)"

  traefik:
    image: "traefik:v2.9"
    container_name: "traefik"
    command:
      #- "--log.level=DEBUG"
      - "--api.insecure=true"
      - "--api.dashboard=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
    ports:
      - "80:80"
      - "8080:8080"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
