AWS EKS Cluster Creation with Terraform¶
This project provisions a production-ready Amazon EKS cluster using Terraform.
We build the cluster step by step, covering IAM roles, networking, node groups, and outputs.
Kubernetes Architecture¶

AWS EKS Cluster Architecture¶

Terraform Remote State Datasource for VPC and EKS Cluster Terraform Projects¶
- Sharing data across Terraform projects

Step-01: Project Structure¶
| File | Description |
|---|---|
c1_versions.tf |
Required Terraform + AWS provider versions |
c2_variables.tf |
Input variables (region, cluster name, etc.) |
c3_remote-state.tf |
Remote backend for Terraform state (S3 + DynamoDB) |
c4_datasources_and_locals.tf |
AWS data sources and local values |
c5_eks_tags.tf |
Common tags for resources |
c6_eks_cluster_iamrole.tf |
IAM role for EKS control plane |
c7_eks_cluster.tf |
EKS cluster resource definition |
c8_eks_nodegroup_iamrole.tf |
IAM role for EKS worker node groups |
c9_eks_nodegroup_private.tf |
Private node group configuration |
c10_eks_outputs.tf |
Useful Terraform outputs (kubeconfig, cluster details) |
Step-02: Steps to Provision¶
# Terraform Initialize
terraform init
# Terraform Validate
terraform validate
# Terraform Plan
terraform plan
# Terraform Apply
terraform apply -auto-approve
Step-03: Configure kubectl cli to access EKS cluster¶
# EKS kubeconfig
aws eks update-kubeconfig --name <cluster_name> --region <aws_region>
# List Kubernetes Nodes
kubectl get nodes
# List Kubernetes Pods
kubectl get pods -n kube-system
Step-04: Browse EKS Cluster features on AWS Console¶
- Go to AWS Console -> EKS
- Review Tabs
- Overview
- Resources
- Compute
- Networking
- Add-ons
- Access
- Observability
- Update history
