# Terraform EKS Cluster in Private VPC

This project demonstrates the creation of an EKS cluster in a private VPC using Terraform. All resources, including VPC, subnets, route tables, NAT gateways, and the EKS cluster, were built from scratch without using pre-built Terraform modules.

## Features

- **EKS Cluster**: Provisioned using AWS EKS.

- **Private VPC**: Custom-built VPC with private subnets for enhanced security.

- **Subnets and Route Tables**: Handled manually to control traffic flow.

- **NAT Gateways**: Ensuring private access for instances in the private subnets.

- **IAM Roles and Policies**: Configured for EKS workers and control plane.

## Prerequisites

- AWS Account

- Terraform 1.x.x

- AWS CLI

- kubectl

## Usage

1. Clone the repository:

    ```bash

    git clone https://github.com/niveshsunny/terraform-eks.git

    cd terraform-eks

    ```

2. Initialize the project:

    ```bash

    terraform init

    ```

3. Apply the configuration:

    ```bash

    terraform apply

    ```

4. Update your kubeconfig to interact with the cluster:

    ```bash

    aws eks --region  update-kubeconfig --name 

    ```

5. Verify your cluster:

    ```bash

    kubectl get nodes

    ```

## Resources

- **VPC**: Custom-built VPC with private subnets.

- **EKS Cluster**: Created from scratch.

- **NAT Gateways**: Provisioned for internet access in the private subnets.

- **IAM Roles and Policies**: Configured for the EKS cluster.

## Notes

- This project does not use pre-built Terraform modules to maintain full control and customization.

- Ensure your AWS credentials are properly configured before applying the Terraform plan.
