无法使用 docker-compose.yml 从 Rails sidekiq 连接到 selenium-hub

Question

尝试使用 docker-compose 从 sidekiq worker 运行 selenium。 如果我从 rails 任务运行作业，它会很好地工作。但是当我从 sidekiq 运行时它不起作用。 从 sidekiq 运行 Job 时出现此错误。

Errno::EADDRNOTAVAIL: 无法打开与 localhost:4444 的 TCP 连接（无法分配请求的地址 - connect(2) 用于“localhost”端口 4444）

docker-compose.yml

version: '3'
services:
  db:
    image: mysql
    volumes:
      - ./tmp/db:/var/lib/postgresql/data
  web:
    build: .
    command: bundle exec rails s -p 3000 -b '0.0.0.0'
    volumes:
      - .:/myapp
    ports:
      - "3000:3000"
    depends_on:
      - db

  redis:
    image: redis:latest
    ports:
      - 6379:6379

  sidekiq:
    build: .
    command: bundle exec sidekiq
    volumes:
      - .:/myapp
    depends_on:
      - db
      - redis

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

请建议我如何解决此问题

我让它与这样的 docker-compose.yml 一起工作：

version: '3.3'
services:
  selenium-hub:
    container_name: selenium_hub
    image: selenium/hub:3.12.0-cobalt
    ports:
      - 4444:4444
    networks:
      - selenium_grid

  selenium-chrome:
    container_name: selenium_chrome
    image: selenium/node-chrome:3.12.0-cobalt
    environment:
      - HUB_HOST=selenium_hub
      - HUB_PORT=4444
    volumes:
      - /dev/shm:/dev/shm
    networks:
      - selenium_grid
    depends_on:
      - selenium-hub

  selenium-firefox:
    container_name: selenium_firefox
    image: selenium/node-firefox:3.12.0-cobalt
    environment:
      - HUB_HOST=selenium_hub
      - HUB_PORT=4444
    volumes:
      - /dev/shm:/dev/shm
    networks:
      - selenium_grid
    depends_on:
      - selenium-hub

networks:
  selenium_grid:
    driver: bridge
