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.

Helm provider hands-on

It is exciting to introduce this aspect of Crossplane. It is precisely the crossroads where it unifies infrastructure automation and application automation. After creating an infrastructure resource, we would be interested in doing additional operations. For example, after deploying a Kubernetes cluster, we would be interested in setting up Prometheus or deploying an application in the remote Kubernetes cluster. Helm Crossplane provider can perform this operation.

Similarly, after provisioning a database, we will be interested in creating tables. SQL provider can perform these activities from Crossplane. The examples open a way to define all application dependencies in Crossplane and package them along with infrastructure. This section will go through a hands-on journey to experiment with Crossplane Helm provider. We will use GCP to create a Kubernetes cluster. It will fit well within the free tier limits. The following diagram represents how the Helm provider...
