Description

If I define a NestedStack and add custom tags, these tags are applied to child resources, but not the NestedStack itself. Is it possible to apply these tags to the NestedStack as well?

export class MyStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props: cdk.StackProps) {
    super(scope, id, props);

    new MyNestedStack();
  }
}

export class MyNestedStack extends cdk.NestedStack {
    constructor(scope: Construct, id: string, props: cdk.NestedStackProps) {
        super(scope, id, props);

        cdk.Tags.of(this).add('tag-1', 'value-1');
        cdk.Tags.of(this).add('tag-2', 'value-2');

        new s3.Bucket(this, 'MyBucket');
  }
}

Nested Stack tags:

{}

S3 Bucket Tags

{
  "tag-1": "value-1",
  "tag-2": "value-2"
}

Use Case

We create n NestedStacks, some of the tags we require are specific to individual nested stacks and can not be set in the parent scope. If tags specified on a cdk.NestedStack class applied to the NestedStack (in addition to the stack resources) this would resolve our issue.

Proposed Solution

Apply tags to NestedStacks when declared on class of type cdk.NestedStack.
