AWS Cloud Development Kitを試してみます。

##参考

https://awslabs.github.io/aws-cdk/getting-started.html
https://awslabs.github.io/aws-cdk/reference.html

##Getting startedをベースに試してみる

$ npm install -g aws-cdk
/Users/atsum/.nodebrew/node/v9.11.1/bin/cdk -> /Users/atsum/.nodebrew/node/v9.11.1/lib/node_modules/aws-cdk/bin/cdk
+ aws-cdk@0.18.1
added 265 packages in 30.324

$ cdk --version
0.18.1 (build 9f7af21)

プロジェクトを作成する

mkdir hello-cdk
cd hello-cdk
git init
npm init -y

$ npm init -y
Wrote to /Users/atsum/Work/cdk/hello-cdk/package.json:

{
  "name": "hello-cdk",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

依存関係の追加

npm install @aws-cdk/cdk

npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN hello-cdk@1.0.0 No description
npm WARN hello-cdk@1.0.0 No repository field.

+ @aws-cdk/cdk@0.18.1
added 10 packages in 3.275s

AWS CDK Appの定義

$ emacs index.js

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

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

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

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

new MyApp().run();

クレデンシャル設定

$ aws configure
AWS Access Key ID [****************XHSQ]: ************
AWS Secret Access Key [****************f4/2]: **************
Default region name [ap-northeast-1]: 
Default output format [None]:

デフォルトで実行するappを指定する

$ emacs cdk.json
{
  "app": "node index.js"
}

stackの確認

$ cdk ls -l
- name: hello-cdk
  environment:
    name: 793493288704/ap-northeast-1
    account: "793493288704"
    region: ap-northeast-1

テンプレートの元となるスクリプトを記載する

emacs index.js
const cdk = require('@aws-cdk/cdk');

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

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

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

new MyApp().run();

jsからテンプレートに変換

$ cdk synth hello-cdk
Resources:
  CDKMetadata:
    Type: AWS::CDK::Metadata
    Properties:
      Modules: "@aws-cdk/cdk=0.18.1,@aws-cdk/cx-api=0.18.1,hello-cdk=1.0.0"

デプロイする

$ cdk deploy
hello-cdk: deploying...
hello-cdk: creating CloudFormation changeset...
 0/2 | 16:17:37 | CREATE_IN_PROGRESS   | AWS::CloudFormation::Stack | hello-cdk User Initiated
 0/2 | 16:17:42 | CREATE_IN_PROGRESS   | AWS::CDK::Metadata | CDKMetadata 
 0/2 | 16:17:45 | CREATE_IN_PROGRESS   | AWS::CDK::Metadata | CDKMetadata Resource creation Initiated

 2/2 | 16:17:47 | CREATE_COMPLETE      | AWS::CloudFormation::Stack | hello-cdk 

 ✅  hello-cdk

Stack ARN:
arn:aws:cloudformation:ap-northeast-1:793493288704:stack/hello-cdk/ad103a90-ee26-11e8-a16d-0a5da605f772

##S3バケットを作成

$ cat 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');
    }
}

new MyApp().run();

$ npm install @aws-cdk/aws-s3
npm WARN hello-cdk@1.0.0 No description
npm WARN hello-cdk@1.0.0 No repository field.

+ @aws-cdk/aws-s3@0.18.1
added 6 packages in 3.993s

$ cdk synth hello-cdk
