title: Ports used from traefik reverse proxy service are not reported from "docker ps" command
body: <p>The "docker ps" command does not show the traefik port 8080 and other ports used from the service</p>
  
  <p>The traefik service is defined in a docker-compose.yml as follow:</p>
  
  <pre><code>...
    traefik:
      image: traefik:1.7-alpine
      command: --docker --docker.swarmMode  --docker.domain=mylocal.swarm --docker.watch --api --logLevel=INFO \
        --entryPoints='Name:http Address::80' \
        --entryPoints='Name:https Address::443 TLS'
      networks:
        - net-traefik
      deploy: *default-deploy
      ports:
        - "8091:80"
        - "8093:443"
        - "8080:8080"
      volumes:
        - /var/run/docker.sock:/var/run/docker.sock
      logging: *default-logging
  </code></pre>
  
  <p>The "docker ps" command output is:</p>
  
  <pre class="lang-sh prettyprint-override"><code>CONTAINER ID    IMAGE                COMMAND                 CREATED    STATUS        PORTS      
  ...
  635a4e017bb5    traefik:1.7-alpine   "/entrypoint.sh o…"      …          …            80/tcp     
  ...
  </code></pre>
  
  <p>Why only the port 80 is displayed? I expected to find also 443 and 8080</p>
