Windows Builder

The WindowsBuilder allows you to get started with a builder class to configure with required setup as you prepare a blueprint for setting up EKS cluster with windows to run your windows workloads.

The WindowsBuilder creates the following: - An EKS Cluster` with passed k8s version and cluster tags. - A non-windows nodegroup for standard software with parameters passed. - A windows nodegroup to schedule windows workloads with parameters passed.

Input Parameters

WindowsOptions which takes inputs to WindowsBuilder supports following parameters:

  • kubernetesVersion : Required field, Kubernetes version to use for the cluster
  • instanceClass: Required field, Instance class to use for the cluster
  • instanceSize: Required field, Instance size to use for the cluster
  • nodeRole: optional, Node IAM Role to be attached to Windows and Non-windows nodes.
  • windowsAmiType: Required field, AMI Type for Windows Nodes. For example WINDOWS_FULL_2022_X86_64.
  • desiredNodeSize: Optional field, Desired number of nodes to use for the cluster
  • minNodeSize: Optional field, Minimum number of nodes to use for the cluster
  • maxNodeSize: Optional field, Maximum number of nodes to use for the cluster
  • blockDeviceSize: Optional field, Block device size
  • noScheduleForWindowsNodes: Optional field, No Schedule for Windows Nodes, this allows Windows nodes to be marked as no-schedule by default to prevent any linux workloads from scheduling.
  • clusterProviderTags: Optional field, Cluster Provider Tags
  • genericNodeGroupTags: Optional field, Generic Node Group Tags for non-windows nodes which run standard cluster software.
  • windowsNodeGroupTags: Optional field, Windows Node Group Tags.

Demonstration - Building Windows on EKS Cluster

The below usage helps you with a demonstration to use WindowsBuilder to configure a required setup as you prepare a blueprint for setting up windows nodes on a new EKS cluster.

import * as blueprints from "@aws-quickstart/eks-blueprints";
import * as ec2 from "aws-cdk-lib/aws-ec2";
import * as eks from "aws-cdk-lib/aws-eks";
import * as iam from "aws-cdk-lib/aws-iam";
import { Construct } from "constructs";
import { WindowsBuilder, WindowsOptions } from '../common/windows-builder';
import { WindowsVpcCni } from "./vpc-cni";

export default class WindowsConstruct {
    build(scope: Construct, id: string) {
        const account = process.env.CDK_DEFAULT_ACCOUNT!;
        const region = process.env.CDK_DEFAULT_REGION!;
        const stackID = `${id}-eks-blueprint`;

        const nodeRole = new blueprints.CreateRoleProvider("blueprint-node-role", new iam.ServicePrincipal(""),

        const options: WindowsOptions = {
            kubernetesVersion: eks.KubernetesVersion.of("1.28"),
            instanceClass: ec2.InstanceClass.M5,
            instanceSize: ec2.InstanceSize.XLARGE4

        const addOns: Array<blueprints.ClusterAddOn> = [
            new WindowsVpcCni()

            .resourceProvider("node-role", nodeRole)
                new blueprints.VpcProvider()
            .build(scope, stackID);
