CDK

Intro

#IaC
#TypeScript (also use Python,Golang)

Installation

$ npm install -g aws-cdk
#! check cdk installation
$ cdk --version

Pre-requirement

Ready AWS Account
Give Right Permission to Account

Init

$ cdk bootstraap aws://{account}/{region}

Create CDK Project

$ cdk init --language typescript

Key File: lib/cdk-workshop-stack.ts
For example: create a simple lambda

lib/cdk-workshop-stack.ts
import * as cdk from "aws-cdk-lib";
import * as lambda from "aws-cdk-lib/aws-lambda";

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

    // defines an AWS Lambda resource
    const firstLambda = new lambda.Function(this, "HelloHandler", {
      runtime: lambda.Runtime.NODEJS_14_X,
      code: lambda.Code.fromAsset("lambda"),
      handler: "hello.handler",
    });
  }
}

Create lambda/hello.js

lambda/hello.js
exports.handler = async function (event) {
  // console.log("request:", JSON.stringify(event, undefined, 2));
  return {
    statusCode: 200,
    headers: { "Content-Type": "text/plain" },
    body: `Hello, CDK!\n`,
  };
};

CDK Command

#! Deploy
$ cdk deploy
#! Destroy / Delete
$ cdk destroy

Step Function

之前工作用到一些工具，使用到 AWS step function , 因此在這裡也筆記一下... 也在公司後端組例會分享了一下（以下就是我分享的 PPT ）：

其實我覺得我用的情境很簡單，只是用 Map 的方式啟動 lambda . 這個 lambda 就是我用來處理下載與上傳到 s3 指定位置... 說真的應用的情境真的很不多... 還有更多著墨的空間。

另外，自己同時也針對此寫了兩個版本，用 SAM 和用 CDK 的版本...

一、CDK 的版本

import * as cdk from "@aws-cdk/core";
import * as lambda from "@aws-cdk/aws-lambda";
import * as stepfunctions from "@aws-cdk/aws-stepfunctions";
import * as tasks from "@aws-cdk/aws-stepfunctions-tasks";
import * as logs from "@aws-cdk/aws-logs";
import * as s3 from "@aws-cdk/aws-s3";
import * as ec2 from "@aws-cdk/aws-ec2";
import * as dotenv from "dotenv";

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

    // 將裡面比較敏感的資訊用env 包起來, 注意後面的path 要正確
    dotenv.config({ path: __dirname + "/../.env" });

    // 我要上傳音檔的S3 目標 arn:aws:s3:::test 為虛構（我忘了把這個也包env了哈哈）
    const bucket = s3.Bucket.fromBucketArn(this, "test", "arn:aws:s3:::test");

    // 負責前面呼叫step function 的 lambda
    const downloadAudioLambda = new lambda.Function(
      this,
      "downloadAudioLambda",
      {
        runtime: lambda.Runtime.NODEJS_12_X,
        timeout: cdk.Duration.seconds(25),
        handler: "index.handler",
        code: lambda.Code.fromAsset("lambda/downloadAudioLambda"),
      }
    );

    bucket.grantPut(downloadAudioLambda);

    const downloadAudioJob = new tasks.LambdaInvoke(this, "Calllambda", {
      lambdaFunction: downloadAudioLambda,
      outputPath: "$.Payload",
    });

    const map = new stepfunctions.Map(this, "ExampleMapState");
    map.iterator(downloadAudioJob);

    const logGroup = new logs.LogGroup(this, "StepFunctionLogs");

    const stateMachine = new stepfunctions.StateMachine(this, "StateMachine", {
      definition: map,
      logs: {
        destination: logGroup,
        level: stepfunctions.LogLevel.ERROR,
      },
    });

    const testVpc = ec2.Vpc.fromLookup(this, "vpc-dev", {
      vpcId: process.env.VPCID,
    });

    const processorLambda = new lambda.Function(this, "processorLambda", {
      runtime: lambda.Runtime.NODEJS_12_X,
      handler: "index.handler",
      timeout: cdk.Duration.seconds(25),
      code: lambda.Code.fromAsset("lambda/processor"),
      vpc: testVpc,
      environment: {
        ENDPOINT: process.env.ENDPOINT ?? "localhost",
        DATABASE: process.env.DATABASE ?? "db",
        DBUSERNAME: process.env.DBUSERNAME ?? "root",
        PASSWORD: process.env.PASSWORD ?? "password",
        NODE_ENV: process.env.NODE_ENV ?? "test",
        statemachine_arn: stateMachine.stateMachineArn,
      },
    });

    stateMachine.grantStartExecution(transferLambda);
  }
}

總之，上面我就是用 CDK 先創建我的 lambda , 然後把那個要放到 state machine 的建立"task", 給予我另外一個 lambda 有 startExecution 的權限.... 簡單完成！

二、SAM 的版本

總之，有些原因，我另外又學習怎麼用 SAM 製作 state machine XDD

AWSTemplateFormatVersion: "2010-09-09"
Transform: AWS::Serverless-2016-10-31
Description:
  download audio file from huaxi to trigger audio transcoder

      DefinitionUri: statemachine/audioFile_processer.json
      DefinitionSubstitutions:

            BucketName: 'test'
        - S3WritePolicy:
            BucketName: 'test'

  ProcessorFunction:
    Type: AWS::Serverless::Function
    Properties:
      FunctionName: processor
      Timeout: 20
      CodeUri: functions/processor/
      Handler: index.handler
      Runtime: nodejs12.x
      Environment:
        Variables:
          DATABASE: dbname
          DBUSERNAME: dbusername
          PASSWORD:dbpassword
          NODE_ENV: test
          statemachine_arn: !Ref ProcessAudioFileStateMachine
      Policies:
        - StepFunctionsExecutionPolicy:
            StateMachineName: !GetAtt ProcessAudioFileStateMachine.Name

其實說真的 CDK 和 SAM 沒有多大差別，只是 CDK 你可以用比較程式化的去做那個 state machine language （就是 sam 裡面要包的那個 json 啦！），像我，實在懶得去構想那個 json 怎麼寫（啊我就不是 JSON 工程師啊～），所以先用 CDK 產生 state machine , 然後上 AWS 控制台上面把那一串 json 抓下來，放到我的 sam 這裏... 整理一下，CDK detroy 一下，sam 的 template.yaml 調整一下，一個下午搞定啦！（不過我好像忘了在 sam 裡面宣吿 log 去接 state machine 啦 XDDD 之後再研究吧！）
