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.

Building a new provider

Crossplane providers are nothing but a bundle of related Managed Resources (MRs). MRs are opinionated custom controllers and custom resources combined into one-to-one mapping with external resources, enabling us to manage those resources from Kubernetes. Onboarding new resources as MRs into an existing or new provider is a time-consuming process. The Crossplane community has worked hard to onboard most of the essential resources with Crossplane-native controllers in the last few years. With the recent development in the Crossplane community to auto-generate, Crossplane providers from Terraform provider enabled 100% resource coverage for all cloud resources. In addition to the provider for all primary cloud providers, we also have providers for other external resources, such as GitLab, Helm, SQL, and Argo CD. Visit the Crossplane website or Upbound Registry to explore the available providers.
