Traefik v2.1.4 - How to create a static route and redirect to a specific host and port

I'm a beginner with Traefik v2.1.4. I'm using in a docker container. I'm trying to set up a static route. I found some examples using the toml configuration file.

[providers]
[providers.file]
[http]
    [http.routers]
        [http.routers.netdata]
            rule = "Host(`netdata.my-domain.com`)"
            service = "netdata"
            entrypoint=["http"]

    [http.services]
          [http.services.netdata.loadbalancer]
            [[http.services.netdata.loadbalancer.servers]]
              url = "https://192.168.0.2:19999"

Following this example I would like to convert it to docker labels of my docker-compose.

My docker-compose file:

version: "3.7"
services:

  traefik:
    image: traefik:v2.1.4
    container_name: traefik
    restart: always
    command:
      - "--log.level=DEBUG"
      - "--api.insecure=false"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.letsresolver.acme.tlschallenge=true"
      - "--certificatesresolvers.letsresolver.acme.email=my-email@domain.com"
      - "--certificatesresolvers.letsresolver.acme.storage=/letsencrypt/acme.json"
    labels:
      - "traefik.enable=true"
      # middleware redirect
      - "traefik.http.middlewares.redirect-to-https.redirectscheme.scheme=https"
      # global redirect to https
      - "traefik.http.routers.redirs.rule=hostregexp(`{host:.+}`)"
      - "traefik.http.routers.redirs.entrypoints=web"
      - "traefik.http.routers.redirs.middlewares=redirect-to-https" 
      # dashboard
      - "traefik.http.routers.traefik.rule=Host(`traefik.my-domain.com`)"
      - "traefik.http.routers.traefik.service=api@internal"
      - "traefik.http.routers.traefik.middlewares=admin"
      - "traefik.http.routers.traefik.tls.certresolver=letsresolver"
      - "traefik.http.routers.traefik.entrypoints=websecure"
      - "traefik.http.middlewares.admin.basicauth.users=user:hash-passwordXXX"

    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      - "./letsencrypt:/letsencrypt"
      - "/var/run/docker.sock:/var/run/docker.sock:ro"

 networks:
    default:
        external:
            name: network

I don't think this is possible.
Docker labels only allow to route to the docker service (container) having the label.
So using only labels you can not route to services running on another hosts - for that you need a file provider.
