【SAM】最新の状態を自動で反映したい
この記事を共有する
はじめに
パーソル＆サーバーワークスの嶋田です。
SAMを使って開発をしていると、sam build / sam deploy コマンドはよく使いますよね。
でも、ちょっとした修正ごとにこのサイクルを回すのは少々面倒だと感じませんか？
そんなあなたに、sam sync コマンドのご紹介です。
sam sync とは
sam sync コマンドは、ローカルのアプリケーションの変更をAWSクラウドに同期する。
公式には上記の通り書かれていますが、もう少し具体化すると、
SAMテンプレートや、SAMでデプロイしているコードの変更を、タイムリーに自動適用してくれます。
本ブログを通じて、実際の動作を見てみましょう。

sam sync を使ってみる
sam sync を使う環境が整ったので、実際に使っていきます。
$ sam sync The SAM CLI will use the AWS Lambda, Amazon API Gateway, and AWS StepFunctions APIs to upload your code without performing a CloudFormation deployment. This will cause drift in your CloudFormation stack. **The sync command should only be used against a development stack**. Confirm that you are synchronizing a development stack. Enter Y to proceed with the command, or enter N to cancel: [Y/n]: Y Queued infra sync. Waiting for in progress code syncs to complete... Starting infra sync.

コードを書き換えてみる
例えば、現在の hello world の結果を返すAPIを、
hello sam の結果を返すように、コードを書き換えます。
$ cat ./hello-world/app.mjs
/**

*/
export const lambdaHandler = async (event, context) => {
const response = {
statusCode: 200,
body: JSON.stringify({
message: 'hello sam',
})
};
return response;
};
コードを書き換えると、以下のように sam sync のCLIに動きが見えます。

同期が完了したようです。
APIを再度実行してみる
$ curl https://xfk8gt8fk5.execute-api.ap-northeast-1.amazonaws.com/Prod/hello/
{"message":"hello sam"}
hello sam と応答してくれてますね。
このように、sam build sam deploy せずとも動的に最新のコードを反映してくれます。
CloudFormationリソースについても、同様に反映してくれます。
こちらの動作も確認してみましょう。
リソースを追加してみる
まず、既存のhello-worldアプリケーションを複製します。
$ cp -r ./hello-world ./hello-sam-world
続いて、複製したアプリケーションのreturnを、 hello sam から hello sam world に書き換えます。
/**

export const lambdaHandler = async (event, context) => {
const response = {
statusCode: 200,
body: JSON.stringify({
message: 'hello sam world',
})
};
return response;
};
最後に、template.ymlを書き換えて、今回追加した hello sam world を返すAPIを追加します。
