Adding docker labels traefik.<servicename>.* properties like

- traefik.mycustomservice.port=443
  -  traefik.mycustomservice.frontend.rule=Path:/mycustomservice
   - traefik.anothercustomservice.port=8080
  -  traefik.anothercustomservice.frontend.rule=Path:/anotherservice

all traffic to frontend /mycustomservice is redirected to the port 443 of the container while using /anotherservice will redirect to the port 8080 of the docker container

 - `traefik.docker.network`: Set the docker network to use for connections to this container
 
+If several ports need to be exposed from a container, the services labels can be used
+- `traefik.<service-name>.port=443`: create a service binding with frontend/backend using this port. Overrides `traefik.port`.
+- `traefik.<service-name>.protocol=https`: assign `https` protocol. Overrides `traefik.protocol`.
+- `traefik.<service-name>.weight=10`: assign this service weight. Overrides `traefik.weight`.
+- `traefik.<service-name>.frontend.backend=fooBackend`: assign this service frontend to `foobackend`. Default is to assign to the service backend.
