self.driver_.get("http://www.stockbroking.com.my") 时出现 Selenium WebDriverException
Selenium WebDriverException when self.driver_.get("http://www.stockbroking.com.my")
我有一个名为“Kenbot”的 Ken**** 股票购买机器人（Ken**** 是一家股票经纪公司）已经 运行 一年了，我已经花了大部分时间尝试消除错误的时间。
直到最近，我遇到了一个新的追溯问题。它只在某些日子偶尔发生，而在其他日子则不会。
Kenbot 通过我的 Synology NAS 在 docker 图像（selenium/standalone-chrome：最新）上运行，每天早上在市场开盘前它会下订单购买少量股票。它通过 Selenium 工作。
现在除了使用 @retry 装饰器，如果遇到 WebDriverException 将重新尝试下股票订单，我没有其他解决方案。
我该如何解决这个问题？

假设你使用的是docker-compose，你可以添加www.stockbroking.com.my的IP:
...
services:
<app>:
extra_hosts:
- "www.stockbroking.com.my:<add IP address here>"
...
或者，docker run --add-host www.stockbroking.com.my:<add IP address here> ...
或使用 Python docker SDK，如评论中所示：
container = client.containers.run('selenium/standalone-chrome', user =
'root', detach=True, auto_remove=True, environment =
["TZ=Asia/Kuala_Lumpur"], ports={'4444/tcp':('127.0.0.1',4444)},
