An AWS CDK Construct that enforces encryption on an S3 bucket

pip install mbonig.secure-bucket==1.0.7


A CDK L3 Construct for a Secure Bucket

This is an AWS CDK L3 Construct used to demonstrate the development and publishing process with the AWS CDK.

Please refer to the blog post here for more information.


Just import and use it.

import cdk = require('@aws-cdk/core');
import {SecureBucket} from 'secure-bucket';

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

    new SecureBucket(this, 'myBucket',{});

Encryption options

This is just a wrapper around an S3 Bucket and the props are shared.

However, you cannot supply an UNENCRYPTED option for the encryption property. If you do, or don't set it at all, it will use the BucketEncryption.KMS_MANAGED value by default.

Integration Test

If you want to see full usage, you can run

$ cdk synth

to produce a basic stack with one SecureBucket resource

L2 Construct - Inheritance vs Composition

This construct is a wrapper around a standard L2 Bucket. However, because it wraps it, you can't just use it in all the same places you could use a standard L2 bucket. You have to pass around the public field .bucket from the construct. This was done as it's more representative of the types of constructs I expect people to build (composed of multiple L2s). However, if you were to actually want to use this construct in a production environment you'd probably use the inheritance model instead. Checkout the feature/inheritance branch for that version.
