 my_container:
    container_name: my_container
    restart: always
    build: .
    labels:
      - "traefik.backend=my_container"
      - "traefik.enable=true"
      - "traefik.docker.network=web"
      - "traefik.frontend.rule=Host:api.mydomain.com"
Solution

  • You should be able to achieve this with segments: https://docs.traefik.io/configuration/backends/docker/#on-containers-with-multiple-ports-segment-labels

    traefik.<segment_name>.frontend.rule=EXP
traefik.<segment_name>.port=PORT
