Description

I'd like to be able to create Windows node groups for EKS.

The EKS docs show that with eksctl you can create windows node groups but the terraform eks node group module doesn't allow it.

https://docs.aws.amazon.com/eks/latest/userguide/launch-windows-workers.html

eksctl create nodegroup \
--region us-west-2 \
--cluster windows \
--name windows-ng \
--node-type t2.large \
--nodes 3 \
--nodes-min 1 \
--nodes-max 4 \
--node-ami-family WindowsServer2019FullContainer

I see a list of amis here:
https://github.com/weaveworks/eksctl/blob/ef183767fa7a19205d02e63375aacb889b55b732/pkg/ami/static_resolver_ami.go

Docs show this:
https://eksctl.io/usage/custom-ami-support/

With 4 AMI families, Amazon Linux, Ubuntu, Windows Server Full, Windows Server Core.

New or Affected Resource(s)

• aws_eks_node_group

Potential Terraform Configuration

resource "aws_eks_node_group" "windows_nodes" {
  cluster_name    = "foo"
  node_group_name = "foo-windows"
  node_role_arn   = "${data.aws_iam_role.node.arn}"
  subnet_ids      = ["${data.aws_subnet_ids.eks_private.ids}"]

  ami_type        = "WindowsServer2019FullContainer"

  scaling_config {
    desired_size = "1"
    max_size     = "5"
    min_size     = "1"
  }
}

@gibsonje The eksctl command you showed does not create an EKS managed nodegroup, instead creating a standard unmanaged nodegroup.
I think there need to be enhancements from Amazon to enabled managed Windows nodegroups.

Hi @gibsonje 👋 Thank you for submitting this. As mentioned above, this functionality is not directly available via the EKS API at the moment. This support can be tracked at aws/containers-roadmap#584. When the API support becomes available we will support this directly in the Terraform AWS Provider, but for now we will opt to close this feature request until that time comes. 👍

Sounds good, thanks!
