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.

Chapter 8: Knowing the Trade-offs

In the previous few chapters, we learned a lot about Crossplane, from its basics to many advanced patterns. Also, we introduced the idea of a unified approach to both application and infrastructure automation. This chapter will step back to analyze and approach configuration management for unified automation holistically. The chapter is heavily influenced by the white paper Declarative application management in Kubernetes (https://goo.gl/T66ZcD) by Brian Grant, a Kubernetes Steering Committee emeritus. The white paper mainly covers the Kubernetes Resource Model (KRM). We will cover the topics in this chapter from the KRM and Crossplane Resource Model (XRM) perspectives. The chapter will define the scope of the unified automation approach. It will continue by looking into many more concepts, such as the tools available, common pitfalls along the way, and the trade-off in using different patterns. In a way, it’s a revisit of the API boundaries...
