How to add a tag to an AWS-CDK construct

Question

How to add a tag to an AWS-CDK specific construct or even better one tag definition to all ressources created within the stack?

Answer 1

According to aws-cdk doc you can add a tag to all constructs/ressources. Tags will inherits to constructs within same "tree". That's pretty cool.

Example using aws-cdk based on java:

MyStack stack = new MyStack(app, "nameOfStack");
Tag.add(stack, "tag_foo", "tag_foo");

AWS-Doc CDK Tagging

AWS CDK Reference: Tag

Tags can be applied to any construct. Tags are inherited, based on the scope. If you tag construct A, and A contains construct B, construct B inherits the tag.

Example from aws-cdk doc:

import { App, Stack, Tag } from require('@aws-cdk/core');

const app = new App();
const theBestStack = new Stack(app, 'MarketingSystem');

// Add a tag to all constructs in the stack
Tag.add(theBestStack, 'StackType', 'TheBest');
