aws_s3: Implement requester pays

[giusedroid]

Describe the feature

Enable S3 requester pays

Enabling s3 requester pays as a property of BucketProperty would help customers managing the state of their payment options directly from code.

    const bucket = new s3.Bucket(this, 'RequesterPaysBucket', {
      //requester pays
      paymentRequests: true, // or something like that
    });

Use Case

As of now, I could not find a way to declaratively set this option on a bucket.

Proposed Solution

there's no CloudFormation equivalent option on AWS::S3::Bucket, so this may not be an easy fix. Here's a link to the docs where they show how to implement this via an HTTP request.

Potentially this could be implemented as a custom resource depending on the bucket

// lambda/set-requyester-pays.js
const { S3Client, PutBucketRequestPaymentCommand } = require('@aws-sdk/client-s3');

exports.handler = async (event) => {
    const bucketName = event.ResourceProperties.BucketName;

    if (!bucketName) {
        return {
            status: 'FAILED',
            reason: 'Bucket name is required',
        };
    }

    const s3Client = new S3Client({ region: process.env.AWS_REGION });

    const params = {
        Bucket: bucketName,
        RequestPaymentConfiguration: {
            Payer: 'Requester'
        }
    };

    try {
        await s3Client.send(new PutBucketRequestPaymentCommand(params));
        return {
            status: 'SUCCESS',
            reason: 'Requester pays enabled successfully',
        };
    } catch (error) {
        return {
            status: 'FAILED',
            reason: `Error enabling requester pays: ${error.message}`,
        };
    }
};

// within a stack
// Custom Resource Lambda to set requester pays
    const setRequesterPaysLambda = new lambda.Function(this, 'SetRequesterPaysLambda', {
      runtime: lambda.Runtime.NODEJS_18_X,
      handler: 'set-requester-pays.handler',
      code: lambda.Code.fromAsset(path.join(__dirname, '../lambda'))
    });

    // Custom Resource to trigger the lambda
    const customResourceProvider = new Provider(this, 'CustomResourceProvider', {
      onEventHandler: setRequesterPaysLambda,
    });

    new CustomResource(this, 'SetRequesterPaysCustomResource', {
      serviceToken: customResourceProvider.serviceToken,
      properties: {
        BucketName: bucket.bucketName,
      },
    });

@giusedroid Good morning. As rightly pointed out by you, there is an open issue https://github.com/aws-cloudformation/cloudformation-coverage-roadmap/issues/123 in CloudFormation repository. The constructs in CDK are limited by the functionality provided by CloudFormation. Once CloudFormation specification supports RequesterPays property, it would be available as part of CDK CfnBucket L1 construct. The workaround to use custom resource as suggested in https://github.com/aws-cloudformation/cloudformation-coverage-roadmap/issues/123#issuecomment-932532908 is the way to go forward as of now.

Thanks, Ashish
