Selenium docker crashes on Windows (unknown error: DevToolsActivePort file doesn't exist)
Selenium docker crashes on Windows (unknown error: DevToolsActivePort file doesn't exist)
总结：适用于 mac 但不适用于 windows。请注意：这不是其他类似问题的重复，我已经在 SO 和其他地方研究了一天多。
我构建了一个超级简单的脚本，它执行 2 个 dockers 容器：一个带有 chrome 浏览器，chrome 驱动程序，另一个带有测试。它在 Linux 上运行良好，但是当我在 Windows 上启动容器时，我得到了；
root@4ba2401510ed:/wdir# ../usr/bin/php7.1 chromeTest.php
PHP Fatal error: Uncaught Facebook\WebDriver\Exception\UnknownErrorException: unknown error: Chrome failed to start: crashed.
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has
crashed.)

有人以前看过这个吗？看起来 Docker 只是在 Windows 上表现不同，并使 docker 容器内的 Chrome 崩溃..
我尝试了建议的解决方案，例如添加 --headless、--sandbox 等，但它似乎确实与 docker 在 windows 上的工作方式有关。

这可能是由于 windows 更新和 docker 图像未相应更新时发生的问题。尝试回滚到以前的版本可以解决它。
此外，尝试使用不同的 docker 图片进行试验，例如
"selenium/standalone-chrome"
将有助于调试问题。
在 windows WSL 更新
之前有效的先前图像示例
image: selenium/standalone-chrome:89.0.4389.90-chromedriver-89.0.4389.23-20210315
在实例化驱动程序对象时可能还需要调整一些选项，这是一个工作示例
$options = new ChromeOptions();
$options->addArguments(["no-sandbox","headless", "disable-dev-shm-usage"]);
$capabilities = DesiredCapabilities::chrome();
$capabilities->setCapability(ChromeOptions::CAPABILITY_W3C, $options);
$driver = RemoteWebDriver::create($host, $capabilities);
