Multi-environment management with Terraform and Flux CD

In the final section of this book, you’ll explore a detailed application of the concepts we’ve discussed, using a Kubernetes cluster (minikube) to manage a multi-environment setup with Flux CD for IaC. This real-world example will demonstrate how to effectively deploy separate environments for development (dev), staging (staging), and production (prod). Figure 10.4 illustrates the described example:
