End-to-End Automation with Kubernetes and Crossplane

By: Arun Ramakani

Overview of this book

In the last few years, countless organizations have taken advantage of the disruptive application deployment operating model provided by Kubernetes. With Crossplane, the same benefits are coming to the world of infrastructure provisioning and management. The limitations of Infrastructure as Code with respect to drift management, role-based access control, team collaboration, and weak contract make people move towards a control-plane-based infrastructure automation, but setting it up requires a lot of know-how and effort. This book will cover a detailed journey to building a control-plane-based infrastructure automation platform with Kubernetes and Crossplane. The cloud-native landscape has an overwhelming list of configuration management tools that can make it difficult to analyze and choose. This book will guide cloud-native practitioners to select the right tools for Kubernetes configuration management that best suit the use case. You'll learn about configuration management with hands-on modules built on popular configuration management tools such as Helm, Kustomize, Argo, and KubeVela. The hands-on examples will be patterns that one can directly use in their work. By the end of this book, you'll be well-versed with building a modern infrastructure automation platform to unify application and infrastructure automation.

Specialized and extendable abstraction

As we scale the number of applications deployed in Kubernetes, there could be an exponential proliferation of configurations to manage. Managing a high volume of KRM/XRM configuration files is prone to human error, is challenging to keep in sync, and requires a highly skilled workforce. Reuse is the key to keeping the volume of configurations low. But customization requirements at the individual team level will not allow us to reuse unless we have an easy and quick way to do so. Also, agile and product engineering practices will add additional pressure from a minimal external dependency perspective. Specialized and extendable abstraction is vital to address these problems. Let’s start with specialized abstraction in the following section.

Specialized abstraction

Specialized abstraction is a technique where we build a basic abstraction and reuse the base abstraction to make specialized abstractions that handle custom requirements....
