This AWS Solutions Konstruk implements an AWS IoT topic rule, an AWS Lambda function and Amazon DynamoDB table with the least privileged permissions.

Here is a minimal deployable pattern definition:

const { IotToLambdaToDynamoDBProps,  IotToLambdaToDynamoDB } = require('@aws-solutions-konstruk/aws-iot-lambda-dynamodb');

const props: IotToLambdaToDynamoDBProps = {
    deployLambda: true,
    lambdaFunctionProps: {
        code: lambda.Code.asset(`${__dirname}/lambda`),
        runtime: lambda.Runtime.NODEJS_12_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 IotToLambdaToDynamoDB(stack, 'test-iot-lambda-dynamodb-stack', props);

Initializer

new IotToLambdaToDynamoDB(scope: Construct, id: string, props: IotToLambdaToDynamoDBProps);

Parameters

• scope Construct
• id string
• props IotToLambdaToDynamoDBProps
