Selenium 从docker-compose.yml运行Zalenium时自动拉取依赖映像

我有以下docker-compose.yml文件。当我运行此命令时，会收到消息“请运行'docker pull elgalu/selenium'，或通过--seleniumImageName使用您自己的兼容映像”。如果我拉图像，我的测试运行良好。如何在运行撰写文件时自动提取图像，而不是手动提取图像。谢谢你的帮助

version: '3'

services:

  zalenium:
    image: repo.forge.lmig.com/docker/dosel/zalenium
    container_name: zalenium
    depends_on:
       - selenium
    ports:
      - "4444:4444"
    restart: unless-stopped
    tty: true
    command: ["start", "--desiredContainers", "5", "--maxDockerSeleniumContainers", "10","--sauceLabsEnabled","false","--screenWidth", "1920", "--screenHeight", "1080"]
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /Users/goutham/git/selenium-tests/test-output/videos:/home/seluser/videos
    privileged: true   
    networks:
      mynetwork:
        aliases:
          - chrome


 selenium-tests: 
    image: selenium-tests:latest
    container_name: selenium-tests-container      
    depends_on:
      - zalenium
    networks:
      mynetwork:  
    volumes:
     - /Users/goutham/git/selenium-tests/test-output:/test-output

networks:
  mynetwork:
    driver: bridge

添加新服务

  dep:
    image: elgalu/selenium
    command: echo 0
    restart: "no" # ensures it does not get recreated

将此添加到Zalenium中

  depends_on:
       - selenium
       - dep # ensures pull/launch order

如果指定环境变量，则可以自动提取图像

PULL_SELENIUM_IMAGE=true
