When defining a container in your docker-compose.yml file, a few fields are important for better consistency and ease of management. Consider using the following recommended configuration:

services:
  <CONTAINER_NAME>:
    image: traefik/whoami
    hostname: <CONTAINER_NAME>
    container_name: <CONTAINER_NAME>
    restart: unless-stopped
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.<CONTAINER_NAME>.rule=Host(`my-company.com`)"
      - "traefik.http.routers.<CONTAINER_NAME>.tls.certresolver=letsencrypt"

Simply replace <CONTAINER_NAME> with the desired name for your container, for example frontend.
