Terraform EKS Cluster Setup

This repository contains Terraform configuration files for setting up an Amazon EKS cluster along with a VPC, security groups, and necessary outputs. The following files are included:

• eks-cluster.tf: Manages the EKS cluster and associated resources.
• outputs.tf: Defines the output values such as the cluster endpoint and security group ID.
• security-group.tf: Configures security groups for the EKS cluster.
• variables.tf: Declares variables used throughout the Terraform configuration.
• versions.tf: Specifies the required Terraform version and provider versions.
• vpc.tf: Configures the Virtual Private Cloud (VPC) and related networking resources.

Prerequisites

Before you begin, ensure that you have:

• Terraform installed on your local machine.
• AWS CLI configured with appropriate access.
• An S3 bucket for storing Terraform state files.

Setup Instructions

1. Clone the Repository

git clone https://github.com/your-username/terraform-eks-setup.git
cd terraform-eks-setup

2. Initialize Terraform

Run the following command to initialize Terraform, which will download the necessary provider plugins.

terraform init

3. Review and Modify Variables

Review the variables.tf file to adjust any variables specific to your environment, such as region, VPC CIDR, etc.

4. Plan the Deployment

Generate an execution plan to preview the changes Terraform will apply:

terraform plan

5. Apply the Configuration

Apply the configuration to create the EKS cluster and related resources:

terraform apply

6. Access the EKS Cluster

Once the cluster is created, you can access it using the Kubernetes CLI (kubectl). The cluster details can be found in the output values.
