Docker 问题：Chrome 无法启动：异常退出（未知错误：DevToolsActivePort 文件不存在）：Chrome 浏览器和驱动程序 78

Question

我最近将 Chrome 浏览器更新到了 78 版本，这导致了一个问题。

我正在 Linux Docker 容器中以 Headless Chrome 模式运行 Selenium 测试，使用最新的 chrome-78.0.3904.108、driver-78.0.3904.105 和 selenium-3.141.0、specflow 包 -3.1.67。

我已经尝试了这个论坛上建议的几乎所有功能，以便在 Docker 中无头运行 Chrome。

 case "Headless_Chrome":


                        string driverPath = "/opt/selenium/";
                        string driverExecutableFileName = "chromedriver";

                        ChromeDriverService service_headless = ChromeDriverService.CreateDefaultService(driverPath, driverExecutableFileName);

                       chrome_options.BinaryLocation = "/opt/google/chrome/chrome";

                        chrome_options.AddArgument("--no-sandbox");
                        chrome_options.AddArgument("--headless");
                        chrome_options.AddArgument("--window-size=1420,1080");
                        chrome_options.AddArgument("--disable-extensions");
                        chrome_options.AddArgument("--proxy-server='direct://'");
                        chrome_options.AddArgument("--proxy-bypass-list=*");
                        chrome_options.AddArgument("--disable-gpu"); //even will come redundant in case of linux 
                        chrome_options.AddArgument("--disable-dev-shm-usage"); // to fix -  error: unknown error: session deleted because of page crash
                        chrome_options.AddArgument("--remote-debugging-port=9222");
                        chrome_options.AddArgument("--remote-debugging-address=0.0.0.0");
                        chrome_options.AddArgument("--disable-infobars");
                        chrome_options.AddArgument("--user-data-dir=/data");
                        chrome_options.AddArgument("--disable-features=VizDisplayCompositor"); //to save from zombie chrome process running
                        //chrome_options.AddArgument("--disable-setuid-sandbox");
                        //chrome_options.AddArgument("--privileged"); // can be a security risk
                        //chrome_options.AddArgument("--lang=en_US");
                        //chrome_options.AddArgument("--start-maximized");
                        //chrome_options.AddAdditionalCapability("useAutomationExtension", false);

                        driver = new ChromeDriver(service_headless, chrome_options, TimeSpan.FromSeconds(120));

                     break;

关闭这个问题，

因为根本原因是：项目中使用的 default.srprofile 在 Docker 中不起作用，只是没有被读取。 在 Git 中心 Specflow 提出了一个问题
