Overview
This AWS Solutions Construct implements the AWS Lambda function and AWS Secrets Manager secret with the least privileged permissions.
Here is a minimal deployable pattern definition:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { LambdaToSecretsmanagerProps, LambdaToSecretsmanager } from '@aws-solutions-constructs/aws-lambda-secretsmanager';
import * as lambda from 'aws-cdk-lib/aws-lambda';

const constructProps: LambdaToSecretsmanagerProps = {
lambdaFunctionProps: {
runtime: lambda.Runtime.NODEJS_16_X,
code: lambda.Code.fromAsset(`lambda`),
handler: 'index.handler'
},
};

new LambdaToSecretsmanager(this, 'test-lambda-secretsmanager-stack', constructProps);

Python
from aws_solutions_constructs.aws_lambda_secretsmanager import LambdaToSecretsmanagerProps, LambdaToSecretsmanager
from aws_cdk import (
aws_lambda as _lambda,
Stack
)
from constructs import Construct


LambdaToSecretsmanager(
self, 'test-lambda-secretsmanager-stack',
lambda_function_props=_lambda.FunctionProps(
code=_lambda.Code.from_asset('lambda'),
runtime=_lambda.Runtime.PYTHON_3_9,
handler='index.handler'
)
)

Java
import software.constructs.Construct;

import software.amazon.awscdk.Stack;
import software.amazon.awscdk.StackProps;
import software.amazon.awscdk.services.lambda.*;
import software.amazon.awscdk.services.lambda.Runtime;
import software.amazon.awsconstructs.services.lambdasecretsmanager.*;

new LambdaToSecretsmanager(this, "test-lambda-secretsmanager-stack", new LambdaToSecretsmanagerProps.Builder()
.lambdaFunctionProps(new FunctionProps.Builder()
.runtime(Runtime.NODEJS_16_X)
.code(Code.fromAsset("lambda"))
.handler("index.handler")
.build())
.build());

Pattern Construct Props



Name
Type
Description




existingLambdaObj?
lambda.Function
Existing instance of Lambda Function object, providing both this and lambdaFunctionProps will cause an error.


lambdaFunctionProps?
lambda.FunctionProps
User provided props to override the default props for the Lambda function.


secretProps?
secretsmanager.SecretProps
Optional user provided props to override the default props for Secrets Manager


existingSecretObj?
secretsmanager.Secret
Existing instance of Secrets Manager Secret object, If this is set then the secretProps is ignored


grantWriteAccess?
string
Optional Access granted to the Lambda function for the secret. 'Read' or 'ReadWrite". Default is "Read"


secretEnvironmentVariableName?
string
Optional Name for the Lambda function environment variable set to the ARN of the secret. Default: SECRET_ARN.


existingVpc?
ec2.IVpc
An optional, existing VPC into which this pattern should be deployed. When deployed in a VPC, the Lambda function will use ENIs in the VPC to access network resources and an Interface Endpoint will be created in the VPC for AWS Secrets Manager. If an existing VPC is provided, the deployVpc property cannot be true. This uses ec2.IVpc to allow clients to supply VPCs that exist outside the stack using the ec2.Vpc.fromLookup() method.


vpcProps?
ec2.VpcProps
Optional user-provided properties to override the default properties for the new VPC. enableDnsHostnames, enableDnsSupport, natGateways and subnetConfiguration are set by the pattern, so any values for those properties supplied here will be overridden. If deployVpc is not true then this property will be ignored.


deployVpc?
boolean
Whether to create a new VPC based on vpcProps into which to deploy this pattern. Setting this to true will deploy the minimal, most private VPC to run the pattern: One isolated subnet in each Availability Zone used by the CDK programenableDnsHostnames and enableDnsSupport will both be set to trueIf this property is true then existingVpc cannot be specified. Defaults to false.



Pattern Properties



Name
Type
Description




lambdaFunction
lambda.Function
Returns an instance of lambda.Function created by the construct


secret
secretsmanager.Secret
Returns an instance of secretsmanager.Secret created by the construct


vpc?
ec2.IVpc
Returns an interface on the VPC used by the pattern (if any). This may be a VPC created by the pattern or the VPC supplied to the pattern constructor.



Default settings
Out of the box implementation of the Construct without any override will set the following defaults:
AWS Lambda Function


Configure limited privilege access IAM role for Lambda function


Enable reusing connections with Keep-Alive for NodeJs Lambda function


Enable X-Ray Tracing


Set Environment Variables

(default) SECRET_ARN containing the ARN of the secret as return by CDK secretArn property.
AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)



Amazon SecretsManager Secret


Enable read-only access for the associated AWS Lambda Function


Creates a new Secret

(default) random name
(default) random value



Retain the Secret when deleting the CloudFormation stack
