How to set AWS EKS nodes to use gp3-CodePudding

I'm trying to set my EKS nodes to use gp3 as volume. It's using the default gp2 but I would like to change it to gp3. I'm using terraform to build the infrastructure and the aws_eks_cluster resource (I'm not using the module "eks"). Here is a simple snippet:

resource "aws_eks_cluster" "cluster" {
  name     = var.name
  role_arn = aws_iam_role.cluster.arn
  version  = var.k8s_version
}


resource "aws_eks_node_group" "cluster" {
  capacity_type   = var.node_capacity_type
  cluster_name    = aws_eks_cluster.cluster.name
  disk_size       = random_id.node_group.keepers.node_disk
  instance_types  = split(",", random_id.node_group.keepers.node_type)
  node_group_name = "${var.name}-${local.availability_zones[count.index]}-${random_id.node_group.hex}"
  node_role_arn   = random_id.node_group.keepers.role_arn
  subnet_ids      = [var.private ? aws_subnet.private[count.index].id : aws_subnet.public[count.index].id]
  version         = var.k8s_version
}

I tried to set up the kubernetes_storage_class resource but it's only changing for volumes used by the pods (PV/PVC). I would like to change the nodes volume to gp3.

I didn't find in the documentation and in the github how to do that. Was anyone able to do that?

Thanks.

You can try to setup your own launch template and then reference it in aws_eks_node_group - launch_template argument.

Launch template allows you to configure disk type. AWS provides guide on how to write a launch template correctly.
