docker - Selenium docker 在 Windows 上崩溃(未知错误 : DevToolsActivePort file doesn't exist)

Question

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 和其他地方对此进行了超过一天的研究。

我构建了一个 super 简单的脚本，它执行 2 个 docker 容器:一个带有 chrome 浏览器、chromedriver，另一个带有测试。它在 Linux 上运行良好，但当我在 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.)

有没有人见过这个？看起来 Docker 只是在 Windows 上表现不同，导致 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，但这似乎确实与 docker 在 windows 上的工作方式有关。

这可能是由于 windows 更新和 docker 镜像没有相应更新时发生的问题。尝试回滚到以前的版本可以修复它。

此外，尝试使用不同的 docker 镜像进行实验，例如

"selenium/standalone-chrome"

将有助于调试问题。

在 Windows WSL 更新之前工作的先前图像的示例

image: selenium/standalone-chrome:89.0.4389.90-chromedriver-89.0.4389.23-20210315

一些选项可能还需要在实例化驱动对象时进行调整，这里是一个工作示例

$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);
