AWS LambdaのOSがAmazon Linux 2に変わっていたから中身を覗いてみた

LambdaがNode.js 10をサポートしましたがOSがAmazon Linux 2に変わっています。どのように変わっているのか、中身を少し覗いてみました。

本日AWS LambdaでNode.js v10が利用できるようになりました！！。Lambdaのドキュメントを見るとNode.js 10のOSがAmazon Linux 2になっていました！これはランタイムの中身の違いを確認せねばと思い、中身を覗いてみました。

Building Lambda Functions with Node.js

Lambda Node.js 10のランタイム

ドキュメントの英語版を見るとランタイムの説明として以下の記載があります。Node.js 10ではOSがAmazon Linux 2に変更されています！

Name	Identifier	Node.js Version	AWS SDK for JavaScript	Operating System
Node.js 10	nodejs10.x	10.15	2.437.0	Amazon Linux 2
Node.js 8.10	nodejs8.10	8.10	2.290.0	Amazon Linux

現在Lambdaのコードを変更できるNode.jsのランタイムは、以下になっています。

nodejs4.3
nodejs6.10
nodejs8.10
nodejs10.x

各々のランタイムについて以下の内容を確認してみます。

実行ユーザ
Node.jsのバージョン
デフォルトの環境変数
/直下のディレクトリ一覧
/bin以下のファイル一覧
起動しているプロセスの一覧
ファイルシステム

以下の様なコードでコマンドを実行してログに出力します。

var execSync = require('child_process').execSync;

exports.handler = (event, context, callback) => {
    var cmd = "whoami";
    const result =  execSync(cmd).toString();
    console.log(result);
    callback(null, context.functionName);
};

実行ユーザ

whoamiを実行して実行ユーザを確認します。全てsbx_user1051ユーザでした。

Node.jsのバージョン

node -vを実行してバージョンを確認します。

デフォルトの環境変数

printenvを実行して環境変数を確認します。Node.js 10でAWS_LAMBDA_RUNTIME_APIという環境変数が増えていました。

`/`直下のディレクトリ一覧

ls -al /を実行してルートのディレクトリを確認します。Node.js 10ではbin、lib、lib64、sbinがusr以下へのリンクに変わっています。またselinuxが無くなりrunが増えています。

さいごに

LambdaのNode.js 10はOSがAmazon Linux 2にアップデートされたためコマンドなど一部の動作が異なっています。Node.js 6.10のEOLが間近に迫っていて一気にNode.js 10に上げようと考えている方もいらっしゃると思いますが、ちゃんと動作を確認しないとハマる可能性があるので気をつけて下さい。
