AWS Cloud Development Kitをさわってみた

AWS Cloud Development Kit (Developer Preview)をさわってみました。

どんなもの？

AWSのインフラストラクチャをコードで定義して CloudFormation でプロビジョニングできる優れもの。

チュートリアルをやってみる

S3バケットを作成します。

$ npm install -g aws-cdk
$ mkdir hello-cdk
$ cd hello-cdk
$ git init
$ npm init -y
$ vi index.js
$ vi cdk.json

index.js

const cdk = require('@aws-cdk/cdk');
const s3 = require('@aws-cdk/aws-s3');

class MyStack extends cdk.Stack {
    constructor(parent, id, props) {
        super(parent, id, props);

        new s3.Bucket(this, 'MyFirstBucket', {
            versioned: true
        });
    }
}

class MyApp extends cdk.App {
    constructor(argv) {
        super(argv);

        new MyStack(this, 'hello-cdk');
    }
}

process.stdout.write(new MyApp(process.argv).run());

cdk.json

{
  "app": "node index.js"
}

$ cdk synth hello-cdk
$ cdk deploy

対応サービス

ECSやEKSやNeptune等、比較的新しいサービスにも対応しているようです。

雑感

• これでAWSのインフラエンジニアやCloudformation職人はいらない子に。→ 自分
• 逆に言えば、アプリエンジニアがAWSをさわらない言い訳ができなくなった
• 他のクラウドにも早く対応しないかな
