    ArgoCDAddOn,
    MetricsServerAddon, 
    ClusterAutoScaler, 
    ContainerInsightsAddOn, 
    NginxAddon, 
    CalicoNetworkPolicyAddon, 
    ClusterAddOn
}  from '@shapirov/cdk-eks-blueprint';

const addOns: Array<ClusterAddOn> = [
  new ArgoCDAddOn,
  new MetricsServerAddon,
  new ClusterAutoScaler,
  new ContainerInsightsAddOn,
  new NginxAddon, 
  new CalicoNetworkPolicyAddon,
];

const app = new cdk.App();
new CdkEksBlueprintStack(app, {id: 'east-test-1', addOns: addOns, teams: []}, {
  env: {
      account: '572179936737',
