This AWS Solutions Construct implements an AWS CloudFront fronting an AWS S3 Bucket.

Here is a minimal deployable pattern definition in Typescript:

import { CloudFrontToS3 } from '@aws-solutions-constructs/aws-cloudfront-s3';

new CloudFrontToS3(this, 'test-cloudfront-s3', {});

Initializer

new CloudFrontToS3(scope: Construct, id: string, props: CloudFrontToS3Props);

Parameters

• scope Construct
• id string
• props CloudFrontToS3Props

Pattern Construct Props

Name	Type	Description
existingBucketObj?	s3.IBucket	Existing instance of S3 Bucket object or interface. If this is provided, then also providing bucketProps will cause an error.
bucketProps?	s3.BucketProps	Optional user provided props to override the default props for the S3 Bucket.
cloudFrontDistributionProps?	cloudfront.DistributionProps	Optional user provided props to override the default props for CloudFront Distribution
insertHttpSecurityHeaders?	boolean	Optional user provided props to turn on/off the automatic injection of best practice HTTP security headers in all responses from CloudFront
originPath?	string	Optional user provided props to provide anoriginPath that CloudFront appends to the origin domain name when CloudFront requests content from the origin. The string should start with a /, for example: /production. Default value is '/'
loggingBucketProps?	s3.BucketProps	Optional user provided props to override the default props for the S3 Logging Bucket.
cloudFrontLoggingBucketProps?	s3.BucketProps	Optional user provided props to override the default props for the CloudFront Logging Bucket.
logS3AccessLogs?	boolean	Whether to turn on Access Logging for the S3 bucket. Creates an S3 bucket with associated storage costs for the logs. Enabling Access Logging is a best practice. default - true

Pattern Properties

Name	Type	Description
cloudFrontWebDistribution	cloudfront.CloudFrontWebDistribution	Returns an instance of cloudfront.CloudFrontWebDistribution created by the construct
cloudFrontFunction?	cloudfront.Function	Returns an instance of the Cloudfront function created by the pattern.
cloudFrontLoggingBucket	s3.Bucket	Returns an instance of the logging bucket for CloudFront WebDistribution.
s3BucketInterface	s3.IBucket	Returns an instance of s3.IBucket created by the construct
s3Bucket?	s3.Bucket	Returns an instance of s3.Bucket created by the construct. IMPORTANT: If existingBucketObj was provided in Pattern Construct Props, this property will be undefined
s3LoggingBucket?	s3.Bucket	Returns an instance of s3.Bucket created by the construct as the logging bucket for the primary bucket.

Default settings

Out of the box implementation of the Construct without any override will set the following defaults:

• Configure Access logging for CloudFront WebDistribution
• Enable automatic injection of best practice HTTP security headers in all responses from CloudFront WebDistribution
• CloudFront originPath set to '/'

Amazon S3 Bucket

• Configure Access logging for S3 Bucket
• Enable server-side encryption for S3 Bucket using AWS managed KMS Key
• Enforce encryption of data in transit
• Turn on the versioning for S3 Bucket
• Don't allow public access for S3 Bucket
