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.

Alerts and monitoring

Prometheus and Grafana, the popular tools in the Kubernetes world, can be used for Crossplane monitoring as well. Before starting, we should ensure that the Crossplane pod can emit metrics. It is as simple as setting the metrics parameter to true (--set metrics.enabled=true) during the Helm deployment of Crossplane. We can do it either at the first Crossplane release or upgrade the Helm release using the following command:

# Fresh install with metrics enables
helm install crossplane --namespace crossplane-system crossplane-stable/crossplane --set args='{--debug}' --set metrics.enabled=true
# Helm upgrade with metrics enables
helm upgrade crossplane --namespace crossplane-system crossplane-stable/crossplane --set args='{--debug}' --set metrics.enabled=true

We can split the monitoring and alert setup into three parts:

  • Enable Prometheus to scrape metrics.
  • Set up monitoring alerts.
  • Enable the Grafana dashboard.
  • ...
