docker - docker selenium/standalone-chrome 无法连接到 docker web 服务器

Question

我正在尝试使用 codeception 为使用 docker 容器开发的 php 网站运行测试。我在 web 容器中创建了一个测试文件夹并将 codecept.phar 放在那里。

这是项目的设置：

• 码头工人-compose.yml：

  version: '3'
    services:
      db:
        image: mariadb
        restart: always
        volumes:
          - ./db:/var/lib/mysql
        ports:
          - '3306:3306'
        environment:
          MYSQL_ROOT_PASSWORD: root
      web:
        build: .
        restart: always
        tty: true
        volumes:
          - ./src:/var/www
          - ./build/php.ini:/usr/local/etc/php/php.ini
        ports:
          - '80:80'
        depends_on:
          - db
      chrome:
        image: selenium/standalone-chrome
        restart: always
        ports:
          - '4444:4444'
          - '5900:5900'
        depends_on:
          - web
  

• 验收套件.yml

  actor: AcceptanceTester
  modules:
    enabled:
      - WebDriver:
          url: web
          host: chrome
          browser: chrome
          wait: 15
          window_size: false
      - \Helper\Acceptance
  

我开始容器：

docker-compose up

然后我将 shell 附加到 Web 容器并运行测试：

php codecept.phar build && php codecept.phar run --steps

我正在运行一个简单的测试，它基本上试图检查一个元素是否存在并截取屏幕截图：-test1.php：

$I = new AcceptanceTester($scenario);
$I->amOnUrl('http://127.0.0.1');
$I->makeScreenshot();
$I->waitForElement(".modal");

但是由于 chrome 容器无法连接到 Web 容器，因此测试无法正常运行。屏幕截图显示了一个页面，上面写着：

This site can't be reached
127.0.0.1 refused to connect

这是附加的 shell 运行 codeception 中显示的错误：

[Facebook\WebDriver\Exception\NoSuchElementException] no such element: Unable to locate element: {"method":"css selector","selector":".modal"}
(Session info: chrome=68.0.3440.84)
(Driver info: chromedriver=2.41.578700 (2f1ed5f9343c13f73144538f15c00b370eda6706),platform=Linux 4.9.0-7-amd64 x86_64)

虽然我能够连接到http://127.0.0.1:4444/wd/hub

这是我从运行“docker-compose up”的 shell 中得到的输出：

我认为为 docker-compose 容器建立一个网络应该可以解决这个问题。我尝试按照 docker 文档（网络配置参考）将网络设置为“主机”，但它似乎已经过时，因为版本 3 中不允许使用名称。

还尝试设置从 chrome 到 web 的链接，并在没有 compose 的情况下运行 chrome（docker run --net=host selenium/standalone-chrome），但这并没有改变。

你知道一种方法来完成这项工作吗？谢谢你的帮助！

尝试通过设置允许非本地主机连接到 chromeJAVA_OPTS

    chrome:
      image: selenium/standalone-chrome
      restart: always
      ports:
        - '4444:4444'
        - '5900:5900'
      environment:
        - JAVA_OPTS=-Dwebdriver.chrome.whitelistedIps=
      depends_on:
        - web
