可以连接到在容器上运行的App Service上的Selenium/Selenium/Selenium/standalone-Chrome docker容器

Question

我已经在本地测试了一个docker，其中我拥有硒/独立的奇异容器和一个具有自动化UI测试的dotnet核心。使用Docker组成文件中的主机名设置，我可以成功地连接并运行自动测试。

现在，我正在尝试将它们部署到容器的Azure Web应用程序中，但是Dotnet Core应用程序正在提出一个错误，说它无法连接到其他容器：

我还尝试了Localhost，而不是使用我使用的“ Chrome”值docker撰写文件中的主机名，但也无效。

有技巧吗？

这是我的Docker-Compose：

version: "1.0"
services:
  scrape:
    image: "xxxxxx.azurecr.io/yyyyy:4.0"
    stdin_open: true # docker run -i
    tty: true        # docker run -t
    shm_size: '2gb'
    restart: always
    depends_on:
      - chrome

  selenium:
    image: "selenium/standalone-chrome:latest"
    container_name: "chrome"
    hostname: chrome
    shm_size: '2gb'
    restart: always
    ports:
      - "4444:4444"   

Answer 1

我认为它可以违反Docker-Compose.yml的定义并重命名服务：

version: "1.0"
services:

  chrome:
    image: "selenium/standalone-chrome:latest"
    container_name: "chrome"
    hostname: chrome
    shm_size: '2gb'
    restart: always
    ports:
      - "4444:4444"   

  scrape:
    image: "xxxxxx.azurecr.io/yyyyy:4.0"
    stdin_open: true # docker run -i
    tty: true        # docker run -t
    shm_size: '2gb'
    restart: always
    depends_on:
      - chrome
