## Overview

This Terraform project provisions a private AWS EKS environment in two documented stages: deploy VPC/EC2 infrastructure, then deploy the cluster and its management and monitoring tools. The graph shows the root configurations, reusable modules, and documented add-on branches. Source excerpts were unavailable, so links reflect the README and repository structure rather than unverified resource-level wiring.

Main entry points: [`eks/main.tf`](https://github.com/amanpathak-devops/eks-argocd-aws-lb-controller-terraform/blob/master/eks/main.tf) (EKS deployment), [`vpc-ec2/main.tf`](https://github.com/amanpathak-devops/eks-argocd-aws-lb-controller-terraform/blob/master/vpc-ec2/main.tf) (VPC/EC2 deployment), [`eks/helm-lb-controller.tf`](https://github.com/amanpathak-devops/eks-argocd-aws-lb-controller-terraform/blob/master/eks/helm-lb-controller.tf) (Load balancer controller), [`eks/argocd-helm.tf`](https://github.com/amanpathak-devops/eks-argocd-aws-lb-controller-terraform/blob/master/eks/argocd-helm.tf) (ArgoCD setup)
