php - 在 docker 容器中使用 Selenium 的 Codeception 无法看到测试它的站点

Question

我的网站使用 docker-compose 在 LEMP 堆栈上运行，一切正常。

我遵循了 Selenium docker 的官方文档，我的 Composer 文件是他们的摘录副本:

version: "3"
services:
  selenium-hub:
    image: selenium/hub:3.12.0-cobalt
    container_name: selenium-hub
    ports:
      - "4444:4444"
  chrome:
    image: selenium/node-chrome:3.12.0-cobalt
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub
      - HUB_PORT=4444
  firefox:
    image: selenium/node-firefox:3.12.0-cobalt
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub
      - HUB_PORT=4444

然后我已经完全按照文档配置了代码接收:
acceptance.suite.yml

actor: AcceptanceTester
modules:
    enabled:
        - WebDriver:
            url: http://172.22.1.2
            browser: chrome
        - \Helper\Acceptence

TestCest.php

...
public function tryToTest(AcceptanceTester $I)
{
    $I->amOnPage('/');
    $I->see('Homepage');
}
...

运行测试时，它们超时并失败说 This site can't be reached . docker 容器肯定正在运行，并且可以通过 Web 浏览器通过容器 IP 172.22.1.2 访问

当我使用默认的 PhpBrowser 时，测试全部运行并正常工作，因此似乎 codeception 无法访问 selenium docker 容器。对此有何建议？

编辑.........
为了清楚起见，添加 docker-compose

version: "3.1"
services:

    mariadb:
      image: mariadb:10.1
      container_name: reports-mariadb
      working_dir: /application
      volumes:
        - .:/application
      environment:
        - MYSQL_ROOT_PASSWORD=reports
        - MYSQL_DATABASE=reports
        - MYSQL_USER=reports
        - MYSQL_PASSWORD=reports
      ports:
        - "8011:3306"
      networks:
        reports:
          ipv4_address: 172.22.1.3

    webserver:
      image: nginx:latest
      container_name: reports-nginx
      working_dir: /application
      volumes:
          - .:/application
          - ./dev/nginx/nginx.conf:/etc/nginx/conf.d/default.conf
      ports:
       - "8010:80"
      networks:
        reports:
          ipv4_address: 172.22.1.2

    php-fpm:
      build: dev/php-fpm
      container_name: reports-php-fpm
      working_dir: /application
      volumes:
        - .:/application
        - ./dev/php-fpm/php-ini-overrides.ini:/etc/php/7.2/fpm/conf.d/99-overrides.ini
      networks:
        reports:
          ipv4_address: 172.22.1.4

networks:
  reports:
    driver: bridge
    ipam:
      config:
        - subnet: 172.22.1.0/24

Answer 1

在发布问题后它来到我这里......它默认在本地主机上查看，但由于应用程序在虚拟网络 172.22.1.0/24 内运行，与应用程序容器相比，它显然是不同的本地主机。

所以我将容器移到我的主 docker-compose 文件中并添加了 selenium-hub像这样到虚拟网络:

version: "3.1"
services:

    mariadb:
      image: mariadb:10.1
      container_name: reports-mariadb
      working_dir: /application
      volumes:
        - .:/application
      environment:
        - MYSQL_ROOT_PASSWORD=reports
        - MYSQL_DATABASE=reports
        - MYSQL_USER=reports
        - MYSQL_PASSWORD=reports
      ports:
        - "8011:3306"
      networks:
        reports:
          ipv4_address: 172.22.1.3

    webserver:
      image: nginx:latest
      container_name: reports-nginx
      working_dir: /application
      volumes:
          - .:/application
          - ./dev/nginx/nginx.conf:/etc/nginx/conf.d/default.conf
      ports:
       - "8010:80"
      networks:
        reports:
          ipv4_address: 172.22.1.2

    php-fpm:
      build: dev/php-fpm
      container_name: reports-php-fpm
      working_dir: /application
      volumes:
        - .:/application
        - ./dev/php-fpm/php-ini-overrides.ini:/etc/php/7.2/fpm/conf.d/99-overrides.ini
      networks:
        reports:
          ipv4_address: 172.22.1.4

    selenium-hub:
        image: selenium/hub:3.12.0-cobalt
        container_name: selenium-hub
        ports:
          - "4444:4444"
    chrome:
        image: selenium/node-chrome:3.12.0-cobalt
        depends_on:
          - selenium-hub
        environment:
          - HUB_HOST=selenium-hub
          - HUB_PORT=4444
    firefox:
        image: selenium/node-firefox:3.12.0-cobalt
        depends_on:
          - selenium-hub
        environment:
          - HUB_HOST=selenium-hub
          - HUB_PORT=4444

networks:
  reports:
    driver: bridge
    ipam:
      config:
        - subnet: 172.22.1.0/24

然后你只需要告诉codeception它在哪个主机上运行:

actor: AcceptanceTester
modules:
    enabled:
        - WebDriver:
            url: http://172.22.1.2
            host: 172.22.1.5
            browser: chrome
