Docker容器无法到达本地主机端口4444。为什么?

communication vagrant networking docker selenium

我封装了一个应用程序,它是自动化Selenium测试的测试驱动程序。Selenium服务器(也称为Selenium Hub)运行在另一个容器中,以及本地主机4444下的Firefox节点中。

    image: selgrid:1.1
    ports:
      - "4444:4444"

  firefox:
    #pull latest from docker hub

    volumes:
      - /dev/urandom:/dev/random
    depends_on:
      - hub

    #run testautomation app

我想我的docker作文有错,但我想不出来。请帮忙! 顺便说一句:我在Windows 7上运行,使用Docker和一个Vagrant VM。在我的Vagrantfile中,我将端口4444和9005映射到主机系统。如果打开本地浏览器,找到localhost:4444,我可以看到selenium网格控制台。为什么它在我的应用程序容器中无法工作?

localhost hub

所以连接到 hub:4444

这是我得到的日志

Connect to localhost:4444 [localhost/127.0.0.1] failed: Connection refused

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
