Overview
This AWS Solutions Construct implements an AWS IoT MQTT topic rule and an AWS Lambda function pattern.
Here is a minimal deployable pattern definition:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { IotToLambdaProps, IotToLambda } from '@aws-solutions-constructs/aws-iot-lambda';
import * as lambda from 'aws-cdk-lib/aws-lambda';

const constructProps: IotToLambdaProps = {
lambdaFunctionProps: {
code: lambda.Code.fromAsset(`lambda`),
runtime: lambda.Runtime.NODEJS_16_X,
handler: 'index.handler'
},
iotTopicRuleProps: {
topicRulePayload: {
ruleDisabled: false,
description: "Processing of DTC messages from the AWS Connected Vehicle Solution.",
sql: "SELECT * FROM 'connectedcar/dtc/#'",
actions: []
}
}
};

new IotToLambda(this, 'test-iot-lambda-integration', constructProps);

Python
from aws_solutions_constructs.aws_iot_lambda import IotToLambdaProps, IotToLambda
from aws_cdk import (
aws_iot as iot,
aws_lambda as _lambda,
Stack
)
from constructs import Construct

IotToLambda(self, 'test_iot_lambda',
lambda_function_props=_lambda.FunctionProps(
code=_lambda.Code.from_asset('lambda'),
runtime=_lambda.Runtime.PYTHON_3_9,
handler='index.handler'
),
iot_topic_rule_props=iot.CfnTopicRuleProps(
topic_rule_payload=iot.CfnTopicRule.TopicRulePayloadProperty(
rule_disabled=False,
description="Sends data to kinesis data stream",
sql="SELECT * FROM 'solutions/construct'",
actions=[]
)
))

Java

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.


iotTopicRuleProps?
iot.CfnTopicRuleProps
User provided CfnTopicRuleProps to override the defaults



Pattern Properties



Name
Type
Description




iotTopicRule
iot.CfnTopicRule
Returns an instance of iot.CfnTopicRule created by the construct


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



Default settings
Out of the box implementation of the Construct without any override will set the following defaults:
Amazon IoT Rule

Configure least privilege access IAM role for Amazon IoT

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

AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)
