  vpc_id          = module.vpc.vpc_id
  subnet_ids      = module.vpc.private_subnet_ids

  node_groups = {
    general = {
      instance_types = ["t3.medium"]
      desired_size   = 2
      max_size       = 5
      min_size       = 1
    }
    spot = {
      instance_types = ["t3.large", "t3a.large"]
      desired_size   = 2
      max_size       = 10
      min_size       = 0
