azure - 无法连接到在容器应用程序服务上运行的 selenium/standalone-chrome docker 容器

Question

我在本地测试了一个 docker compose，其中有一个 selenium/standalone-chrome 容器和一个 dotnet core 容器，并实现了自动化 UI 测试。使用 docker compose 文件中的主机名设置，我可以正确连接并成功运行自动化测试。

现在我尝试将它们部署到 Azure Web App for Container，但 dotnet core 应用程序出现错误，指出它无法连接到其他容器:

我还尝试了 localhost，而不是使用 docker compose 文件中的主机名分配的“chrome”值，但它也不起作用。

有什么建议吗？

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

我将其用于反转 docker-compose.yml 上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
