Kubernetes Design Patterns and Extensions

By: Onur Yılmaz

Overview of this book

Before plunging into how Kubernetes works, this book introduces you to the world of container orchestration and describes the recent changes in application development. You'll understand problems that Kubernetes solves and get to grips with using Kubernetes resources to deploy applications. In addition to this, you'll learn to apply the security model of Kubernetes clusters. Kubernetes Design Patterns and Extensions describes how services running in Kubernetes can leverage the platform's security features. Once you've grasped all this, you'll explore how to troubleshoot Kubernetes clusters and debug Kubernetes applications. You also discover how to analyze the networking model and its alternatives in Kubernetes, and apply best practices with design patterns. By the end of this book, you'll have studied all about using the power of Kubernetes for managing your containers.

Extending the Kubernetes API

Kubernetes already has a rich set of resources, starting from pods as building blocks to higher-level resources such as stateful sets and deployments. Modern cloud-native applications can be deployed in terms of Kubernetes resources and their high-level configuration options. However, they are not sufficient when human expertise and operations are required. Kubernetes enables extending its own API with new resources and operates them as Kubernetes-native objects with the following features:

  • RESTful API: New resources are directly included in the RESTful API so that they are accessible with their special endpoints.
  • Authentication and authorization: All requests for new resources go through the steps of authentication and authorization, like native requests.
  • OpenAPI discovery: New resources can be discovered and integrated into OpenAPI specifications...
