aws alb ingress controller constructs for cdk8s

Basic implementation of a aws alb ingress controller construct for cdk8s. Contributions are welcome!

Usage

AWS Load Balance Controller V1

import { App, Chart } from 'cdk8s';
import { Construct } from 'constructs';
import { AlbIngressController } from 'cdk8s-aws-alb-ingress-controller';

export class MyChart extends Chart {
  constructor(scope: Construct, name: string) {
    super(scope, name);
    new AlbIngressController(this, 'albingresscntroller', {
      clusterName: 'EKScluster',
    });
  }
}
const app = new App();
new MyChart(app, 'testcdk8s');
app.synth();

AWS Load Balance Controller V2

only support install in default namespace now!!!

import { App, Chart } from 'cdk8s';
import { AwsLoadBalancerController } from 'cdk8s-aws-alb-ingress-controller';
import * as constructs from 'constructs';

export interface MyChartProps {
  readonly clusterName: string;
}

export class MyChart extends Chart {
  readonly deploymentName: string;
  readonly deploymentNameSpace: string;
  constructor(scope: Construct, name: string, props: MyChartProps) {
    super(scope, name);
    const alb = new AwsLoadBalancerController(this, 'alb', {
      clusterName: props.clusterName,
      createServiceAccount: false,
    });
    this.deploymentName = alb.deploymentName;
    this.deploymentNameSpace = alb.namespace;
  }
}
const app = new App();
new MyChart(app, 'testcdk8s');
app.synth();

Featrue For Add IAM Policy.

• For IRSA add IAM Policy version 1.

// CDK APP like eks_cluster.ts
import { AwsLoadBalancePolicy, VersionsLists } from 'cdk8s-aws-alb-ingress-controller';
import * as eks from '@aws-cdk/aws-eks';
    const cluster = new eks.Cluster(this, 'MyK8SCluster', {
      defaultCapacity: 0,
      mastersRole: clusterAdmin,
      version: eks.KubernetesVersion.V1_18,
    });

    const albServiceAccount = cluster.addServiceAccount('alb-ingress-controller', {
      name: 'alb-ingress-controller',
      namespace: 'kube-system',
    });
    // will help you add policy to IAM Role .
    AwsLoadBalancePolicy.addPolicy(VersionsLists.AWS_LOAD_BALANCER_CONTROLLER_POLICY_V1, albServiceAccount);

• For IRSA add IAM Policy version 2.

// CDK APP like eks_cluster.ts
import { AwsLoadBalancePolicy, VersionsLists } from 'cdk8s-aws-alb-ingress-controller';
import * as eks from '@aws-cdk/aws-eks';
    const cluster = new eks.Cluster(this, 'MyK8SCluster', {
      defaultCapacity: 0,
      mastersRole: clusterAdmin,
      version: eks.KubernetesVersion.V1_18,
    });

    const sa = new eks.ServiceAccount(this, 'albserviceaccount', {
      cluster: cluster,
      name: 'aws-load-balancer-controller',
    });
    AwsLoadBalancePolicy.addPolicy(VersionsLists.AWS_LOAD_BALANCER_CONTROLLER_POLICY_V2, sa );
