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.

Nested and multi-resource XRs

Every software product depends on more than one infrastructure resource. It is essential to build single infrastructure recipes in order for the product teams to consume with a unified experience. The orchestration of infrastructure dependencies should remain abstracted. Such recipes require multiple resources to be composed into a single XR. In all the examples hitherto, we have always composed a single GCP resource inside an XR. Let’s look at an XR sample where multiple GCP resources are composed into a single XR API. The following figure represents the resources and XR APIs that we are going to work with in the example:

Figure 5.8 – Multi-resource nested XR

In addition to multiple resource provisioning in a single XR, we also have a nested XR pattern in Figure 5.8. We are composing three resources within two XRs. The first XR composes two resources, and the second XR composes the first XR and a database resource...
