How to Trigger an AWS Lambda from Kinesis

How to Trigger an AWS Lambda from Kinesis

先建立資料夾拉～～～

mkdir how-to-trigger-lambda-from-kinesis
cd how-to-trigger-lambda-from-kinesis
npx cdk init app --language typescript

安裝 kinesis & lambda

npm i @aws-cdk/aws-kinesis
npm i @aws-cdk/aws-lambda
npm i @aws-cdk/aws-lambda-event-sources

新增一個檔案.env

touch .env

AWS_ACCOUNT_ID=1234567890123
AWS_DEFAULT_REGION=us-east-1
AWS_ACCESS_KEY_ID=xxxxxx
AWS_SECRET_ACCESS_KEY=xxxxxxx

修改 how-to-trigger-lambda-from-kinesis.ts

#!/usr/bin/env node
import 'source-map-support/register';
import * as cdk from '@aws-cdk/core';
import { HowToTriggerLambdaFromKinesisStack } from '../lib/how-to-trigger-lambda-from-kinesis-stack';

const app = new cdk.App();
new HowToTriggerLambdaFromKinesisStack(app, 'HowToTriggerLambdaFromKinesisStack', {
  env: {
      account: process.env.AWS_ACCOUNT_ID,
      region: process.env.AWS_REGION
  },
});

修改 how-to-trigger-lambda-from-kinesis-stack.ts

import * as cdk from '@aws-cdk/core';
import * as kinesis from '@aws-cdk/aws-kinesis';

export class HowToTriggerLambdaFromKinesisStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const stream = new kinesis.Stream(this, 'MyKinesisStream', {
      streamName: 'MyKinesisStream',
    });
  }
}`

新增 src/index.js 撰寫一下lambda code (這次來用一下nodejs寫)

exports.handler = async (event) => {
  event.Records.forEach((record) => {
    console.log('Record: %j', record);
  });
};

準備發佈前

cdk bootstrap
⏳ Bootstrapping environment aws://xxxxxxxx/us-east-2…
✅ Environment aws://xxxxxxx/us-east-2 bootstrapped (no changes).

發佈

cdk deploy

test

aws kinesis list-streams
aws kinesis put-record --data "aGVsbG8sIHdvcmxk" --stream-name MyKinesisStream --partition-key pk1
