1. 安装Docker

docker安装

2. pull Docker镜像

3. 官方操作方法

githup地址

4. 懒得话，看这里：

1. 启动Chrome驱动selenium

docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-chrome:3.141.59-zirconium
docker run -d -p 4444:4444 --shm-size=2g selenium/standalone-chrome:3.141.59-zirconium

2. 启动Firefox驱动selenium

docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-firefox:3.141.59-zirconium
docker run -d -p 4444:4444 --shm-size 2g selenium/standalone-firefox:3.141.59-zirconium

3. 启动Opera驱动selenium

docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-chrome:3.141.59-zirconium
docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-firefox:3.141.59-zirconium
docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-opera:3.141.59-zirconium

4. 独立使用

docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-chrome:3.141.59-zirconium
docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-firefox:3.141.59-zirconium
docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-opera:3.141.59-zirconium

5. 通过网络连接多个selenium

docker network create grid
docker run -d -p 4444:4444 --net grid --name selenium-hub selenium/hub:3.141.59-zirconium
docker run -d --net grid -e HUB_HOST=selenium-hub -v /dev/shm:/dev/shm selenium/node-chrome:3.141.59-zirconium
docker run -d --net grid -e HUB_HOST=selenium-hub -v /dev/shm:/dev/shm selenium/node-firefox:3.141.59-zirconium
docker run -d --net grid -e HUB_HOST=selenium-hub -v /dev/shm:/dev/shm selenium/node-opera:3.141.59-zirconium

3. 爬虫链接脚本

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

driver = webdriver.Remote(
    command_executor="http://127.0.0.1:4444/wd/hub",
    desired_capabilities=DesiredCapabilities.CHROME
)

driver.get("http://www.baidu.com")
print(driver.title)
driver.close()
