gistfile1.txt

import cdk = require('@aws-cdk/core');
import ec2 =  require( '@aws-cdk/aws-ec2');
import eks = require('@aws-cdk/aws-eks');
import iam = require('@aws-cdk/aws-iam');

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

    const vpc = new ec2.Vpc(this, 'eksClusterVPC');
    
    

    const cluster = new eks.Cluster(this, "eksCluster", {
      vpc: vpc,
      defaultCapacityInstance: ec2.InstanceType.of(ec2.InstanceClass.C5, ec2.InstanceSize.LARGE),
      defaultCapacity: 1
    });

  }
}

所以你最後可以了嗎？
