If you want to deploy to a private subnet (private_node_group), you can use labels. follow my code below:

Terraform to create private_node_group:

resource "aws_eks_node_group" "private-nodes" {
  cluster_name    = "cluster_name"
  node_group_name = "private-nodes"
  node_role_arn   = aws_iam_role.nodes.arn
  subnet_ids      = [private_subnet_id_1, private_subnet_id_2]
  labels = {
    nodegroup = "private"
  }
}

.yaml file to deploy k8s. in values.yaml file:

nodeSelector: {
  nodegroup: private
}

template/deployment.yaml file:

spec:
 template:
   spec:
     [...]
     nodeSelector:
       nodegroup: {{ .Values.nodeSelector.nodegroup }}

Follow this guide to create managed nodegroup https://docs.aws.amazon.com/eks/latest/userguide/create-managed-node-group.html

Specify the private subnets while configuring the Networking as mentioned in Point no. 8.
