```ts
export class EksClusterLatestVersion extends Stack {
  constructor(scope: Construct, id: string, props: StackProps) {
    super(scope, id, props);

    const vpc = new ec2.Vpc(this, 'Vpc', { natGateways: 1 });
    const mastersRole = new iam.Role(this, 'Role', {
      assumedBy: new iam.AccountRootPrincipal(),
    });

    // create eks.Cluster of the latest k8s version
    new eks.Cluster(this, 'Cluster', {
      vpc,
      mastersRole,
      version: eks.KubernetesVersion.V1_30,
      kubectlLayer: new KubectlV30Layer(this, 'KubectlLayer'),
      defaultCapacity: 1,
    });
  }
}
```

$ kubectl get no
