The CDK Construct Library for AWS::S3ObjectLambda
The APIs of higher level constructs in this module are experimental and under active development. They are subject to non-backward compatible changes or removal in any future version. These are not subject to the Semantic Versioning model and breaking changes will be announced in the release notes. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.
This construct library allows you to define S3 object lambda access points.
import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as s3 from 'aws-cdk-lib/aws-s3';
import * as s3objectlambda from '@aws-cdk/aws-s3objectlambda-alpha';
import * as cdk from 'aws-cdk-lib';
const stack = new cdk.Stack();
const bucket = new s3.Bucket(stack, 'MyBucket');
const handler = new lambda.Function(stack, 'MyFunction', {
runtime: lambda.Runtime.NODEJS_LATEST,
handler: 'index.handler',
code: lambda.Code.fromAsset('lambda.zip'),
});
new s3objectlambda.AccessPoint(stack, 'MyObjectLambda', {
bucket,
handler,
accessPointName: 'my-access-point',
payload: {
prop: "value",
},
});
Lambdas are currently limited to only transforming GetObject
requests. However, they can additionally support GetObject-Range
and GetObject-PartNumber
requests, which needs to be specified in the access point configuration:
import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as s3 from 'aws-cdk-lib/aws-s3';
import * as s3objectlambda from '@aws-cdk/aws-s3objectlambda-alpha';
import * as cdk from 'aws-cdk-lib';
const stack = new cdk.Stack();
const bucket = new s3.Bucket(stack, 'MyBucket');
const handler = new lambda.Function(stack, 'MyFunction', {
runtime: lambda.Runtime.NODEJS_LATEST,
handler: 'index.handler',
code: lambda.Code.fromAsset('lambda.zip'),
});
new s3objectlambda.AccessPoint(stack, 'MyObjectLambda', {
bucket,
handler,
accessPointName: 'my-access-point',
supportsGetObjectRange: true,
supportsGetObjectPartNumber: true,
});
You can specify an additional object that provides supplemental data to the Lambda function used to transform objects. The data is delivered as a JSON payload to the Lambda:
import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as s3 from 'aws-cdk-lib/aws-s3';
import * as s3objectlambda from '@aws-cdk/aws-s3objectlambda-alpha';
import * as cdk from 'aws-cdk-lib';
const stack = new cdk.Stack();
const bucket = new s3.Bucket(stack, 'MyBucket');
const handler = new lambda.Function(stack, 'MyFunction', {
runtime: lambda.Runtime.NODEJS_LATEST,
handler: 'index.handler',
code: lambda.Code.fromAsset('lambda.zip'),
});
new s3objectlambda.AccessPoint(stack, 'MyObjectLambda', {
bucket,
handler,
accessPointName: 'my-access-point',
payload: {
prop: "value",
},
});
If you need access to the s3 accesspoint, you can get its ARN like so:
import * as s3objectlambda from '@aws-cdk/aws-s3objectlambda-alpha';
declare const accessPoint: s3objectlambda.AccessPoint;
const s3AccessPointArn = accessPoint.s3AccessPointArn;
This is only supported for AccessPoints created in the stack - currently you're unable to get the S3 AccessPoint ARN for imported AccessPoints. To do that you'd have to know the S3 bucket name beforehand.
