Chapter 3: Terraform + Helm — A Better Abstraction

In Chapter 2, we reached an uncomfortable conclusion: Terraform can manage Kubernetes, but that doesn't mean it should manage everything in Kubernetes. We observed that: Terraform → Versioning, auditing, reproducibility Helm → Simplicity, lifecycle management Terraform + K8s Provider directly → Verbose, giant state, no rollbacks The question that lingers: "Is there a way to have the best of both?" Changing Abstraction Level The problem in Chapter 2 wasn't Terraform itself, it was the level of abstraction we chose. Wrong thinking: Terraform → Manage Deployments, Services, Ingress, etc (individual Kubernetes resources) Right thinking: Terraform → Manage Helm Releases (complete applications as units) It's a subtle but profound change. Instead of Terraform replacing Helm, Terraform orchestrates Helm. Layered Architecture of Responsibilities Let's visualize how responsibilities are divided: ┌──────────────────────────────────────────┐ │ You (Developer) │ │ Define desired state in code │ └──
