-# Welcome to your CDK TypeScript project
+# Langflow on AWS
 
-This is a blank project for CDK development with TypeScript.
+Langflow on AWS は、 Langflow を AWS 上に展開する Project になります。
+この Branch では、AWS CDK を用いて 各種 Dockerfile からコンテナイメージを ECR に展開し、ECS、Aurora MySQL を用いて Langflow を構築します。
 
-The `cdk.json` file tells the CDK Toolkit how to execute your app.
+# デプロイ
+[CloudShell](https://us-east-1.console.aws.amazon.com/cloudshell/home?region=us-east-1)を開きます。
 
-## Useful commands
+以下のコマンドを実行します。
+```shell
+git clone https://github.com/aws-samples/cloud9-setup-for-prototyping
+cd cloud9-setup-for-prototyping
+./bin/bootstrap
+```
 
-* `npm run build`   compile typescript to js
+`Done!` と表示されたら [Cloud9](https://us-east-1.console.aws.amazon.com/cloud9control/home?region=us-east-1#/) から `cloud9-for-prototyping` を開きます。
-* `npm run watch`   watch for changes and compile
+![make-cloud9](./img/langflow-cloud9.png)
-* `npm run test`    perform the jest unit tests
+
-* `cdk deploy`      deploy this stack to your default AWS account/region
+以下のコマンドを実行します。
-* `cdk diff`        compare deployed stack with current state
+
-* `cdk synth`       emits the synthesized CloudFormation template
+```shell
+git clone -b aws-cdk-dev2 https://github.com/kazuki306/langflow
+cd langflow/scripts/aws
+cp .env.example .env # この後envの設定が必要ならここで追記
+npm ci
+cdk bootstrap
+cdk deploy
+```
+表示される URL にアクセスします。
+```shell
+Outputs:
+LangflowAppStack.NetworkURLXXXXXX = http://alb-XXXXXXXXXXX.elb.amazonaws.com
+```
+
+# 環境の削除
+`Cloud9` で以下のコマンドを実行します。
+```shell
+cdk destroy
+```
+
+
+[CloudFormation](https://us-east-1.console.aws.amazon.com/cloudformation/home?region=us-east-1#/getting-started)を開き、`aws-cloud9-cloud9-for-prototyping-XXXX` を選択して削除します。
