Prerequisites

Before you begin, ensure you have the following:

• AWS CLI configured with appropriate access permissions
• Terraform installed
• Admin privileges

Setup Instructions

1. Clone the repository:

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

2. Initialize Terraform:

   Initialize the working directory with the following command:

   terraform init

3. Modify Variables:

   Update the variables.tf file with your custom configurations, such as the desired AWS region, cluster name, or any other variables needed for the deployment.

4. Plan the deployment:

   Preview the actions Terraform will take to create your resources:

   terraform plan

5. Apply the configuration:

   Deploy the EKS cluster by running the following command:

   terraform apply --auto-approve

   You will be prompted to confirm the deployment. Type yes to proceed.

6. Deploy the pre-deploy script:

   Run the pre-deploy.sh script to install necessary binaries

   chmod +x pre-deploy.sh
   bash pre-deploy.sh

7. Access the EKS Cluster:

   After the deployment is complete, you can access your EKS cluster using the AWS CLI. Run the following command to configure kubectl:

   aws eks update-kubeconfig --region <your-region> --name <cluster-name>

Outputs

After successful deployment, Terraform will output important information such as:

• EKS Cluster Name
• VPC ID
• Worker Node IAM Role ARN
• Kubernetes API Server Endpoint

Check the outputs.tf file to customize the outputs.
