环境
-
m1芯片mac
-
selenium/hub:latest
-
selenium/node-chrome:latest
启动命令，根据官网提示配置
docker network create grid
docker run -d -p 4442-4444:4442-4444 --net grid --name hub selenium/hub:latest
docker run -d --net grid -e SE_EVENT_BUS_HOST=hub \
--shm-size="2g" \
-e SE_EVENT_BUS_PUBLISH_PORT=4442 \
-e SE_EVENT_BUS_SUBSCRIBE_PORT=4443 \
selenium/node-chrome:latest
脚本代码
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
hub_url = 'http://10.1.6.65:4444'
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--headless')
driver = webdriver.Remote(
command_executor=hub_url,
options=chrome_options # 使用 options 代替 desired_capabilities
)
driver.get("https://www.baidu.com")
time.sleep(2)
print(driver.title)
print(driver.page_source)
driver.quit()
问题解决
乌龙事件，没仔细查看官网说明文档
selenium/node-chrome 并不支持arm64也就是m芯片的mac平台，因为docker部署容器，只虚拟化应用并未虚拟化内核。
更换为selenium/node-chromium 镜像，重新部署环境
执行成功
使用docker compose部署镜像
docker-compose.yml
