Include

The Include construct can be used to include an existing manifest in a chart.

The following example will include the Kubernetes Dashboard in MyChart:

import { Include } from 'cdk8s';

class MyChart extends Chart {
  constructor(scope: Construct, id: string) {
    super(scope, id);

    const dashboard = new Include(this, 'dashboard', {
      url: 'https://raw.githubusercontent.com/kubernetes/dashboard/v2.4.0/aio/deploy/recommended.yaml',
      // or
      url: 'dashboard.yaml'
    });

    // ...other resources
  }
}

All API objects defined in the included manifest will be added as children ApiObjects under the Include construct’s scope and can be accessed through the apiObject property:

The following example queries for all the Deployment resources in the dashboard:

const deploymentApiObject = dashboard.apiObjects.find(c => c.kind === 'Deployment');

NOTE: names of included objects (metadata.name) are preserved. This means that if you try to include the same manifest twice into the same chart, your manifest will have duplicate definitions of the same objects.
