This Terraform module creates a network and an EKS cluster in AWS Cloud provider . The network can have subnets, security groups, and other resources, and the EKS cluster can have worker nodes and other resources.

To use EKS Module you can edit this section of code

resource "aws_eks_cluster" "demo" {
  name     = "demo"
  version  = "1.24"
  role_arn = aws_iam_role.demo.arn

  vpc_config {
    subnet_ids = [
      aws_subnet.private_us_east_1a.id,
      aws_subnet.private_us_east_1b.id,
      aws_subnet.public_us_east_1a.id,
      aws_subnet.public_us_east_1b.id
    ]
  }

  depends_on = [aws_iam_role_policy_attachment.demo_amazon_eks_cluster_policy]
}

In this architecture, the AWS VPC is divided into two public subnets and two private subnets. Each public subnet has an internet gateway attached and a route table that directs traffic to the internet gateway. Each private subnet has a NAT gateway attached and a route table that directs traffic to the NAT gateway.

The EKS cluster consists of a control plane with master nodes and worker nodes launched in an auto scaling group. The worker nodes use a launch configuration that specifies the AMI, instance type, and other configuration settings. The worker nodes are also associated with a security group that controls inbound and outbound traffic.
