Usage

module "aws_node_pool" {
  source = "../../modules/aws-node-pool"

  # Cluster configuration
  tenant_cluster_name = "my-cluster"
  pool_name          = "workers"
  pool_size          = 3

  # Instance configuration
  instance_type  = "t3a.large"
  ami_id         = "ami-06147ccec7237575f"
  node_disk_size = 50

  # AWS configuration
  aws_region   = "us-west-2"
  aws_zones    = ["us-west-2a", "us-west-2b"]
  aws_vpc_name = ["my-vpc"]
