ОБНОВЛЕНИЕ 0429 - Полный образ докера, который вы можете использовать для работы с Windows, Docker, Chrome, Firefox и тестами. Все ссылки Dockerhub и инструкции в репозитории GitHub - https://github.com/jhealy/aspnet45-docker-selenium.

Мой тест на selenium.Chromedrive c # завершается неудачно с истечением времени ожидания при попытке получить удаленный сервер WebDriver.Основное сообщение выглядит как

HTTP-запрос к удаленному серверу WebDriver для URL http://localhost:49164/session, истекший через 60 секунд

Я подготовил приложение, используяdockerfile и скопируйте в него мое приложение.Я могу запустить приложение снаружи и внутри файла Docker с помощью powershell / wget.

В следующих разделах приведены Dockerfile, команды обеспечения и полный вывод скверных маленьких экранов ошибок.

Исправление для этой конкретной ошибки - установка веб-сокетов в образ моего докера.

Dockerfile ниже: 

FROM mcr.microsoft.com/dotnet/framework/aspnet:4.8    
RUN powershell -Command Add-WindowsFeature Web-WebSockets    
RUN powershell -Command Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))    
RUN powershell -Command choco install googlechrome -y
RUN powershell -Command choco install firefox -y
...
