Terraform AWS Eks Blueprints Addons

Abstract

1. Introduction

Terraform module to deploy Kubernetes addons on Amazon EKS clusters.

2. Objective

Terraform module which provisions addons on Amazon EKS clusters

This project demonstrates how HCL, AWS, Kubernetes can be applied to a real-world Blockchain & Cloud Computing problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Terraform CLI
• Cloud provider account (e.g. AWS) with CLI configured
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/aws-ia/terraform-aws-eks-blueprints-addons.git
cd terraform-aws-eks-blueprints-addons

module "eks_blueprints_addons" {
  source = "aws-ia/eks-blueprints-addons/aws"
  version = "~> 1.0" #ensure to update this to the latest/desired version

  cluster_name      = module.eks.cluster_name
  cluster_endpoint  = module.eks.cluster_endpoint
  cluster_version   = module.eks.cluster_version
  oidc_provider_arn = module.eks.oidc_provider_arn

  eks_addons = {
    aws-ebs-csi-driver = {
      most_recent = true
    }
    coredns = {
      most_recent = true
    }
    vpc-cni = {
      most_recent = true
    }
    kube-proxy = {
      most_recent = true
    }
  }

  enable_aws_load_balancer_controller    = true
  enable_cluster_proportional_autoscaler = true
  enable_karpenter                       = true
  enable_kube_prometheus_stack           = true
  enable_metrics_server                  = true
  enable_external_dns                    = true
  enable_cert_manager                    = true
  cert_manager_route53_hosted_zone_arns  = ["arn:aws:route53:::hostedzone/XXXXXXXXXXXXX"]

  tags = {
    Environment = "dev"
  }
}

module "eks" {
  source = "terraform-aws-modules/eks/aws"

  cluster_name    = "my-cluster"
  cluster_version = "1.29"

  ... truncated for brevity
}

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a CI/CD pipeline with GitHub Actions
• Deploy to a public test network or cloud free tier
• Add monitoring and cost alerts

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Why does this problem need a blockchain or cloud-native design?
2. Explain the smart contract / infrastructure components and how they interact.
3. How are gas costs or cloud costs kept under control?
4. How is the system secured (keys, IAM, access control)?
5. How would the solution scale to many more users?
