Overview

This AWS Solutions Construct provisions an Amazon CloudFront Distribution that serves objects from an AWS S3 Bucket via an Origin Access Control (OAC).

Here is a minimal deployable pattern definition:

Typescript

import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { CloudFrontToS3 } from '@aws-solutions-constructs/aws-cloudfront-s3';

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

Python

from aws_solutions_constructs.aws_cloudfront_s3 import CloudFrontToS3
from aws_cdk import Stack
from constructs import Construct

CloudFrontToS3(self, 'test-cloudfront-s3')

Java

import software.constructs.Construct;

import software.amazon.awscdk.Stack;
import software.amazon.awscdk.StackProps;
import software.amazon.awsconstructs.services.cloudfronts3.*;

new CloudFrontToS3(this, "test-cloudfront-s3", new CloudFrontToS3Props.Builder()
        .build());

Pattern Construct Props

| Name | Type | Description | |:-------------|:----------------|-----------------| |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| |responseHeadersPolicyProps? | cloudfront.ResponseHeadersPolicyProps | Optional user provided configuration that cloudfront applies to all http responses.| |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 '/'| |existingBucketObj?|s3.IBucket|Existing instance of S3 content 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 content bucket. Note - to log S3 access for this bucket to an existing S3 bucket, put the existing log bucket in bucketProps: serverAccessLogsBucket| |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| |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. Note: to use an existing bucketto hold CloudFront logs, pass the existing log bucket in | |logCloudFrontAccessLog|boolean|Optional - Whether to maintain access logs for the CloudFront Logging bucket. Specifying false for this while providing info about the log bucket will cause an error. Default = true | |cloudFrontLoggingBucketAccessLogBucketProps|s3.BucketProps|Optional user provided props to override the default props for the CloudFront Log Bucket Access Log bucket. Providing both this and existingcloudFrontLoggingBucketAccessLogBucket will cause an error. To provide an existing bucket to accept these logs, pass the existing bucket in cloudFrontLoggingBucketProps::serverAccessLogBucket|

Pattern Properties

| Name | Type | Description | |:-------------|:----------------|-----------------| |cloudFrontWebDistribution|cloudfront.Distribution|Returns an instance of cloudfront.Distribution created by the construct.| |cloudFrontFunction?|cloudfront.Function|Returns an instance of the Cloudfront function created by the construct.| |originAccessControl?|cloudfront.CfnOriginAccessControl|Returns an instance of cloudfront.CfnOriginAccessControl created by the construct.| |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.| |cloudFrontLoggingBucket?|s3.Bucket|The S3 bucket created by the construct to hold CloudFront logs. Only populated if the construct creates the bucket (not if an existing bucket is passed in via DistributionProps)| |cloudFrontLoggingBucketAccessLogBucket?|s3.Bucket|The S3 bucket containing the S3 access logs for the CloudFront log bucket. Only populated if the construct creates the bucket (not if the bucket is passed in via cloudFrontLoggingBucketProps::serverAccessLogBucket|

Default settings

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

Amazon CloudFront

• Configure Access logging for CloudFront Distribution
• Enable automatic injection of best practice HTTP security headers in all responses from CloudFront Distribution
• 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
• Retain the S3 Bucket when deleting the CloudFormation stack
• Applies Lifecycle rule to move noncurrent object versions to Glacier storage after 90 days
