This document discusses heterogeneous Kubernetes clusters that include both Windows and Linux containers. It first covers why organizations may want to use Windows containers and why Kubernetes is a good fit to manage both Windows and Linux containers. It then provides instructions on getting started with Kubernetes on Windows using tools like Azure Container Service and ACS Engine. Finally, it acknowledges some current limitations of running Windows containers with Kubernetes and demos a sample configuration before discussing the future of this technology.
