CDK Construct for a private frontend hosting S3 bucket

CDK Private S3 Hosting Construct

This is a CDK construct that creates a private S3 bucket and an Application Load Balancer (ALB) with a listener rule that forwards requests to the S3 bucket.

You can use this construct for a enterprise use case where you want to host a static website in a private network.

Original idea is from this blog post.

Architecture

Usage

To create a private S3 bucket and an ALB with a listener rule that forwards requests to the S3 bucket, you can use the following code:

import { PrivateS3Hosting } from 'cdk-private-s3-hosting';

const privateS3Hosting = new PrivateS3Hosting(this, 'PrivateS3Hosting', {
  domainName: 'cryer-nao-domain.com',
});

After you deploy the stack, you can access the S3 bucket using the ALB's DNS name from the VPC where the stack is deployed.

For example, if you put the hoge.txt file in the S3 bucket, you can access it using the following command:

curl http://cryer-nao-domain.com/hoge.txt

Deploy the frontend assets

You can deploy the frontend assets to the S3 bucket like below:

import { PrivateS3Hosting } from 'cdk-private-s3-hosting';
import * as s3deploy from 'aws-cdk-lib/aws-s3-deployment';

const privateS3Hosting = new PrivateS3Hosting(this, 'PrivateS3Hosting', {
  domainName: 'cryer-nao-domain.com',
});

new s3deploy.BucketDeployment(this, 'DeployWebsite', {
  sources: [s3deploy.Source.asset('./website-dist')],
  destinationBucket: websiteBucket,
  bucket: privateS3Hosting.bucket,
});

After deploying the stack, you can access the website using the domainName you specified from the VPC.

curl http://cryer-nao-domain.com

Note: All access to the path pattern */ will be redirected to /index.html. Therefore, it will function correctly even when the path is set on the frontend and the page is reloaded.
