CDK for Amazon EKS with c5.12xlarge nodegroup

eks-cdk-c512xlarge.ts

import cdk = require('@aws-cdk/core');
import eks = require('@aws-cdk/aws-eks');
import iam = require('@aws-cdk/aws-iam');
import autoscaling = require('@aws-cdk/aws-autoscaling');
import { InstanceType } from '@aws-cdk/aws-ec2';


export class CdkStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    // first define the role
    const clusterAdmin = new iam.Role(this, 'AdminRole', {
      assumedBy: new iam.AccountRootPrincipal()
    });

    // eks cluster with nodegroup of 2x m5.large instances in dedicated vpc with default configuratrion
    const cluster = new eks.Cluster(this, 'Cluster', {
      clusterName: 'cdk-eks3',
      defaultCapacity: 0,
      mastersRole: clusterAdmin
    });

    const asg = new autoscaling.AutoScalingGroup(this, 'NG', {
      vpc: cluster.vpc,
      // on-demand price of c5.12xlarge in us-west-2
      spotPrice: '2.0400',
      instanceType: new InstanceType('c5.12xlarge'),
      machineImage: new eks.EksOptimizedAmi({
        kubernetesVersion: '1.13',
        nodeType: eks.NodeType.NORMAL
      }),
      updateType: autoscaling.UpdateType.ROLLING_UPDATE
    })

    cluster.addAutoScalingGroup(asg, {
      // https://github.com/awslabs/amazon-eks-ami/blob/master/files/eni-max-pods.txt
      maxPods: 234,
      mapRole: true
    })

After the cluster is running, you need update the aws-vpc-cni to 1.5.2 or above

kubectl -n kube-system set image  ds/aws-node aws-node=602401143452.dkr.ecr.us-west-2.amazonaws.com/amazon-k8s-cni:v1.5.2

Does this create a ManagedNodeGroup?

Does this create a ManagedNodeGroup?

No, but the next release of CDK(1.32.0) will be allow you to create managed nodegroup.

Thank you so much!
