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.

Specifying resource limits and configuring autoscaling

As a container orchestrator, Kubernetes comes out of the box with two important features that help to manage your cluster resources:

  • Resource requests and limits for Pod containers
  • HPA, which allows automatic scaling of your Deployments or StatefulSets based on CPU resource usage (stable support), memory resource usage (beta support), or custom metrics (also beta support)

Let's first take a look at specifying resource requests and limits.

Resource requests and limits

When you create a Pod, it is possible to specify how much compute resources its containers requirewe already performed a short exercise on assigning resources for the voting application in the...
