title: Selenium/hub can't recognize selenium/node-chrome-debug while in network_mode = "host"
body: <p>I use Docker to start my Selenium grid in network_mode = "host" so that I can access my local development site.</p>
  
  <p>Both the hub and node started, but when I check <a href="http://localhost:4444/grid/console" rel="nofollow noreferrer">http://localhost:4444/grid/console</a>, there's no node. I wonder if there is any way to solve it.</p>
  
  <p>More info:</p>
  
  <ul>
  <li>Image(s): hub, node-chrome-debug</li>
  <li>Docker-Selenium Image Version(s): 3.14.0-arsenic</li>
  <li>Docker Version: 18.06.0-ce, build 0ffa825</li>
  <li>OS: Ubuntu 18.04</li>
  </ul>
  
  <p>My docker-compose file:</p>
  
  <pre><code>version: "3"
  services:
    selenium-hub:
      image: selenium/hub:latest
      container_name: selenium-hub
      network_mode: "host"
      ports:
        - "4444:4444"
    chrome:
      image: selenium/node-chrome-debug:latest
      depends_on:
        - selenium-hub

      ports:

      environment:
