我将一个应用程序容器化,该应用程序是自动硒测试的测试驱动程序。 Selenium服务器(也称为Selenium Hub)在localhost:4444下的另一个Container和Firefox Node中运行。
但是我的应用程序无法达到它:

我通过docker-compose启动了这些容器:

version: '2'
services:
  hub:
    image: selgrid:1.1
    ports:
      - "4444:4444"

  firefox:
    #pull latest from docker hub
    image: selenium/node-firefox
    volumes:
      - /dev/urandom:/dev/random
    depends_on:
      - hub
    environment:
      - HUB_PORT_4444_TCP_ADDR=hub
      - HUB_PORT_4444_TCP_PORT=4444
  testautomation:
    #run testautomation app
    image: volumetest
    links:
      - "hub"
    ports:
      - "9005:9005"


我想我的docker-compose中有一个错误,但是我无法弄清楚。请帮忙!
顺便说一句:我正在Windows 7上运行,并将Docker与Vagrant VM配合使用。在我的Vagrantfile中,我将端口4444和9005映射到了主机系统。如果打开本地浏览器并访问localhost:4444,则可以看到硒网格控制台。为什么从我的应用程序容器中不起作用?

最佳答案

在您的应用程序容器中,localhost表示当前容器。因此,您需要改用服务名称。您的情况是hub
所以连接到hub:4444
