Running an existing .NET Framework-based application in a Windows container requires creating the Docker image that contains your application, and starting one or more containers to run that image. This topic explains the tasks you must perform to take an existing ASP.NET MVC application and deploy it in a Windows container.
At a minimum, your development machine must be running Windows 10 Anniversary Update or Windows Server 2016 and you need to install Docker for Windows.
After installing and starting Docker, you'll need to right-click on the tray icon and select Switch to Windows containers in order to run Docker images based on Windows.
Visual Studio 2017 is the required version to support adding Docker support for ASP.NET 4.x applications.
Right click the project, select Add -> Docker Support.
A new project type .dcproj is added with the Docker files for building, debugging and publishing the image.
Dockerfile
The base image used is microsoft/aspnet:4.7 which includes microsoft/iis.
FROM microsoft/aspnet:4.7
ARG source
WORKDIR /inetpub/wwwroot
COPY ${source:-obj/Docker/publish} .Start the application by clicking the Docker from the Debug menu; starting the application in a container and attaching the debugger allowing for you to debug your ASP.NET code inside the container.
Just as you would publish your application using the publish wizard, now you can publish your container images to Docker Hub, Azure Container Registry or Azure App Service through the same publishing wizard.
