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 4: Composing Infrastructure with Crossplane

Composing is a powerful construct of Crossplane that makes it unique among its peers, such as the Open Service Broker API or AWS Controllers for Kubernetes. The ability to organize infrastructure recipes in a no-code way perfectly matches the organization’s agile expectation of building a lean platform team. This chapter will take us on a journey to learn about composing from end to end. We will start with a detailed understanding of how Crossplane Composite Resources (XRs) work and then cover a hands-on journey to build an XR step by step.

The following are the topics covered in this chapter:

  • Feeling like an API developer
  • How do XRs work?
  • Postprovisioning of an XR
  • Preprovisioned resources
  • Building an XR
  • Troubleshooting
