【问题描述】：

我想在 DockerCompose 上将 selenium 与 Ruby 一起使用，并在另一台服务器上使用 chrome，但出现错误。
以下是各种代码和错误。

DockerCompose.yml

version: "3"
services:
  ruby:
    build:
      context: .
      dockerfile: RubyDockerFile
    ports:
      - "3000:3000"
    tty: true
  chrome:
    image: selenium/standalone-chrome:4.0.0-beta-3-20210426
    container_name: chrome
    volumes:
      - /dev/shm:/dev/shm
    ports:
      - 4444:4444
      - 5900:5900
      - 7900:7900

RubyDocker 中的 Ruby 代码

driver = Selenium::WebDriver.for :remote, url: 'http://chrome:4444', desired_capabilities: :chrome

错误

【问题讨论】：

当页面加载超过 60 秒时会发生此错误。您的页面加载时间是否超过 60 秒？
感谢您的回复，我可以通过将超时设置为 180 秒而不是 120 秒来连接。非常感谢您的帮助。
是的，就是这样。

【解决方案1】：

如果我延长超时时间，我现在可以连接了。

    client = Selenium::WebDriver::Remote::Http::Default.new
    client.read_timeout = 180 # seconds
    driver = Selenium::WebDriver.for :remote, url: 'http://chrome:4444', desired_capabilities: :chrome, :http_client => client
