🚀 Deploy an EKS Cluster with Terraform – Like a Boss!

📌 Project Overview

This project uses Terraform to provision an Amazon EKS Cluster on AWS. By leveraging Infrastructure as Code (IaC), we automate the deployment of Kubernetes clusters with modular and reusable Terraform configurations.

🔹 Kubernetes (K8s) manages containerized applications efficiently. 🔹 EKS (Elastic Kubernetes Service) is a managed K8s solution on AWS. 🔹 Terraform simplifies infrastructure provisioning with reusable modules.

With this setup, you can deploy, manage, and scale Kubernetes workloads seamlessly!

📁 Project Structure

The repository follows a modular structure for better organization and reusability:

EKS-CLUSTER-TERRAFORM/
│── modules/                   # Terraform modules  
│   ├── eks/                   # EKS module  
│   │   ├── main.tf            # Defines EKS cluster  
│   │   ├── outputs.tf         # Outputs for EKS cluster  
│   │   ├── variables.tf       # Variables for EKS cluster  
│   ├── vpc/                   # VPC module  
│   │   ├── main.tf            # Defines networking resources  
│   │   ├── outputs.tf         # Outputs for VPC  
│   │   ├── variables.tf       # Variables for VPC  
│  
│── .gitignore                 # Git ignore file  
│── LICENSE                    # License file  
│── kubectl.sha256             # Checksum for kubectl  
│── .terraform.lock.hcl         # Terraform lock file  
│── kubernetes.tf              # Kubernetes resources definition  
│── main.tf                    # Root Terraform configuration  
│── outputs.tf                 # Root outputs  
│── provider.tf                 # Provider configurations  
│── README.md                   # Documentation (this file)

🔹 modules/eks – Manages EKS cluster deployment. 🔹 modules/vpc – Handles VPC and networking setup. 🔹 provider.tf – Defines the AWS provider. 🔹 main.tf – Root Terraform script to call modules. 🔹 outputs.tf – Stores and displays useful deployment details.

🎯 Why Terraform for EKS?

Using Terraform for EKS offers several advantages over manual provisioning:

✔ Automated & Repeatable Deployments – Reduce human error. ✔ Infrastructure as Code (IaC) – Easily track changes. ✔ Dependency Awareness – Ensures resources are created in the correct order. ✔ Scalability & Reusability – Modular design for better maintainability.

⚡ Prerequisites

Before you begin, ensure you have the following installed:

✅ AWS Account – Sign up at AWS if you don’t have one. ✅ Terraform – Install from Terraform's official site. ✅ AWS CLI – Install and configure credentials (guide). ✅ kubectl – Kubernetes CLI tool (installation guide). ✅ VS Code (Optional) – Recommended IDE for managing Terraform code.

🚀 Deployment Steps

1️⃣ Clone the Repository

git clone https://github.com/NotHarshhaa/eks-cluster-terraform
cd eks-cluster-terraform

2️⃣ Initialize, Plan & Apply Terraform

Run the following Terraform commands:

terraform init      # Initialize Terraform backend  
terraform plan      # Preview infrastructure changes  
terraform apply     # Deploy infrastructure

📌 Expected Outputs:

• EKS Cluster Name
• Node IP Addresses
• VPC ID

3️⃣ Connect to Your EKS Cluster

After deployment, retrieve cluster credentials:

aws eks update-kubeconfig --name <EKSCLUSTERNAME> --region <AWS_REGION>

Verify cluster connectivity:

kubectl get nodes

4️⃣ Terraform Cloud Integration (Optional)

If you want to integrate with Terraform Cloud:

1️⃣ Go to Terraform Cloud 2️⃣ Create a new Workspace and connect your GitHub repository. 3️⃣ Add the following environment variables:

AWSACCESSKEY_ID
AWSSECRETACCESS_KEY
AWSDEFAULTREGION
CONFIRM_DESTROY

4️⃣ Run the Terraform plan & apply in Terraform Cloud.

5️⃣ Destroy the Infrastructure

To delete the deployed resources, run:

terraform destroy

Alternatively, if using Terraform Cloud, go to: Settings → Destruction & Deletion → Queue destroy plan.
