问题
我正在docker桥接网络中使用mobbrowserproxy启动硒网格。远程驱动程序代理设置配置正确，但我无法从chrome驱动程序连接到代理服务器。我看了所有的问题，但找不到解决办法。
以下是显示驱动程序所需功能/选项的错误。

重现此错误。如果你简单地启动容器并登录chromenode并使用chromedrivercli，你应该会在终端中看到同样的错误。同样，这个问题的目标是通过chromedriver代理设置连接代理容器。

正如您在上面的跟踪中所看到的。所需的功能和选项都在那里。我想弄清楚的是，chrome驱动程序在上面的代理设置中出现这个错误的原因。
在登录页面上查找第一个元素时，我的测试失败了。我不确定你是否需要测试脚本和执行测试脚本的能力来尝试重现这一点，或者这是否是可以指出的。如果需要，我可以将此回购添加到github。

建议
我认为这个脚本最重要的部分是连接到集线器和mob浏览器代理容器的变量
${BMP_HOST} 0.0.0.0
${BMP_PORT} 9090
${SELENIUM} http://0.0.0.0:4444/wd/hub
这个脚本只是向您展示了我是如何设置您在chrome节点上的stacktrace中已经看到的首选项的。
chrome_1 | Only local connections are allowed.
chrome_1 | Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.

这些是我在网上已经发现的问题一二——在这个问题的底部，它通过添加得到了解决，正如你在上面看到的那样。我已经试过了。
--disable-dev-shm-usage'
三这个家伙通过在docker配置中添加ipv6解决了这个问题。但我在docker compose中使用了一个桥接网络，所以我不明白为什么这个选项会很重要。。。。
以前的尝试
我不确定这是chromedriver还是docker的问题。为了完成我已经尝试过的一些事情。。。1.我尝试登录chrome容器并使用chromedriver cli。。。我也犯了同样的错误对问题2的评论我确实尝试使用了包含chromedriver 74的图像作为下一条评论关于问题2 的下一条评论
消除

您需要通过设置docker chrome节点镜像的envJAVA_OPTS：
chrome:
image: selenium/node-chrome:3.141.59-oxygen
depends_on:
- selenium-hub
environment:
- HUB_HOST=selenium-hub
- HUB_PORT=4444
- JAVA_OPTS=-Dwebdriver.chrome.whitelistedIps=
networks:
- caowebtests
