Docker is an open source project which developed in the Linux world, but that doesn't mean Windows and .NET projects can't make use of it. With the Core CLR you can run .NET inside a container running Linux, and with Windows Server 2016 you'll be able to run Docker containers on Windows. In this session we'll start by looking at how Docker works, how containers are defined and run, and what's already out there in public repositories for you to use. We'll see where Docker can fit in integration projects - running core components like message queues and caches, and hosting .NET projects too.
