Episode
Modernizing .NET Apps with Docker, for IT Pros. Part 2.
The second video in the series showing you how to move existing .NET apps to Docker, so you can run them in Azure without any code changes.
In Part 2 I use the open-source PowerShell module, Image2Docker, to extract an ASP.NET 3.5 application from a Windows Server 2003 VM into Docker. The Image2Docker tool extracts the content for IIS apps from the source machine, and generates a Dockerfile.
The Dockerfile is a simple script which sets up your application in Docker. To package the app, you build the Dockerfile into a Docker image - and that's the portable unit. You can share that image on a public or private registry, and anyone with access can pull the image.
To run the app in Docker, you start a container from the image. The image contains everything the app needs to run, so it will behave in the same way on a developer laptop, on a server in the datacenter, and on a Windows VM in Azure.
