Hands-On Kubernetes on Windows

By: Piotr Tylenda

Overview of this book

With the adoption of Windows containers in Kubernetes, you can now fully leverage the flexibility and robustness of the Kubernetes container orchestration system in the Windows ecosystem. This support will enable you to create new Windows applications and migrate existing ones to the cloud-native stack with the same ease as for Linux-oriented cloud applications. This practical guide takes you through the key concepts involved in packaging Windows-distributed applications into containers and orchestrating these using Kubernetes. You'll also understand the current limitations of Windows support in Kubernetes. As you advance, you'll gain hands-on experience deploying a fully functional hybrid Linux/Windows Kubernetes cluster for development, and explore production scenarios in on-premises and cloud environments, such as Microsoft Azure Kubernetes Service. By the end of this book, you'll be well-versed with containerization, microservices architecture, and the critical considerations for running Kubernetes in production environments successfully.

Linux versus Windows containers

Containerization on both Linux and Windows aims to achieve the same goal creating predictable and lightweight environments that are isolated from other applications. For Linux, a classic example of container usage can be running a Python RESTful API written in Flask, without worrying about conflicts between Python modules that are required by other applications. Similarly, for Windows, the containers can be used to host an Internet Information Services (IIS) web server that's entirely isolated from other workloads running on the same machine.

Compared to traditional hardware virtualization, containerization comes at the cost of being tightly coupled with the host OS since it uses the same kernel to provide multiple isolated user spaces. This means that running Windows containers on the Linux OS or running Linux containers on the Windows...
