How to auto-tag AWS resources with Pulumi?

Question

Pulumi · Accepted Answer

Sure, we can auto-tag AWS resources using Pulumi using the `aws.ec2.Tag` resource.

The `Tag` resource allows you to add tags to an existing resources that support tagging. These tags are key-value pairs associated with resources, and they can be used for organizing, sorting, and categorizing resources.

Here is a Pulumi program that creates an Amazon S3 bucket and auto-tags it:

```typescript
import * as aws from "@pulumi/aws";
import * as pulumi from '@pulumi/pulumi';

// Create a new AWS S3 bucket
const bucket = new aws.s3.Bucket('my-bucket');

// Add a tag to the bucket
new aws.ec2.Tag("BucketTag", {
  key: 'Environment',
  value: 'Production',
  resourceId: bucket.id,
});

// Export the bucket name
export const bucketName = bucket.id;
```
This is a simple example of how to use the `aws.ec2.Tag` resource with Pulumi. After creating the S3 bucket, we create a new `Tag` resource. This requires us to specify the `key`, `value`, and `resourceId`.

Here, `key` and `value` are your tag's key-value pair. The `resourceId` is the ID of the resource you intend to apply the tag to. In this case, it's the Bucket `id` passed as `bucket.id`.

This will create the bucket and attach the specified tag to it.
