Istio Ingress Gateway Add-on

Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. An Ingress gateway is a load balancer that handles incoming HTTP and HTTPS traffic to the mesh. It can be used to expose services to the internet, or to enable communication between services within the mesh. Istio Ingress Gateway Add-on installs Istio Ingress Gateway implementing a Kubernetes gateway resource and a set of Envoy proxy instances.


  1. This add-on depends on Istio Base and istio Control Plane Add-ons for cluster-wide resources and CRDs.

Istio Base add-on and Istio Control Plane addon-on must be present in add-on array and must be in add-on array before the Istio Ingress Gateway add-on for it to work, as shown in below example. Otherwise will run into error Assertion failed: Missing a dependency for IstioBaseAddOn.


Add the following as an add-on to your main.ts file to add Istio Control Plane to your cluster

import 'source-map-support/register';
import * as cdk from 'aws-cdk-lib';
import * as blueprints from '@aws-quickstart/eks-blueprints';

const app = new cdk.App();

const istioBase = new blueprints.addons.IstioBaseAddOn();
const istioControlPlane = new blueprints.addons.IstioControlPlaneAddOn()
const istioIngressGateway = new blueprints.addons.IstioIngressGatewayAddOn()

const addOns: Array<blueprints.ClusterAddOn> = [ istioBase, istioControlPlane, istioIngressGateway ];

const blueprint = blueprints.EksBlueprint.builder()
  .build(app, 'my-stack-name');

Configuration Options

  • createNamespace: (boolean) If you want CDK to create the namespace for you
  • version: Version fo the Helm Chart to be used to install
  • values: Arbitrary values to pass to the chart. Refer to Helm Chart documentation for additional details


To validate that installation is successful run the following command:
