HTTPConnectionPool(host='localhost'，port=4444)

Question

我需要在docker容器中运行我的脚本

version: "3"
services:
  chrome:
    image: selenium/node-chrome:4.0.0-rc-1-prerelease-20210823
    shm_size: 2gb
    depends_on:
      - selenium-hub
    environment:
      - SE_EVENT_BUS_HOST=selenium-hub
      - SE_EVENT_BUS_PUBLISH_PORT=4442
      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443
    ports:
      - "6900:5900"

  selenium-hub:
    image: selenium/hub:4.0.0-rc-1-prerelease-20210823
    container_name: selenium-hub
    ports:
      - "4444:4444"
   app:
        build:
            context: . 
        volumes:
            - . :/home/saimon/
        network_mode: "host"
        depends_on:
            - selenium-hub
            - chrome
        command:
            python3 app.py
        environment:
            - SELENIUM_REMOTE_HOST=selenium-hub

在我的应用程序I中：

driver = webdriver.Remote(command_executor='http://selenium-hub:4444/wd/hub',
                                           desired_capabilities=DesiredCapabilities.CHROME, options=self.chrome_options)

我制作:船坞-构图制作

sudo坞-编写运行--rm应用程序或坞-编写-f坞-复合. app向上

并显示此错误：

NewConnectionError('上的port=4444对象引起:未能建立新连接: Errno -3名称解析中的临时失败)

如果您希望能够从应用程序容器连接到network_mode: "host"，请删除http://selenium-hub:4444

还应该尝试使用env-var。

import os 

host = os.environ['SELENIUM_REMOTE_HOST']
driver = webdriver.Remote(command_executor='http://{}:4444/wd/hub'.format(host),
  ...
