An AWS Cloud Development Kit (AWS CDK) stage は、一緒にデプロイするように設定された 1 つ以上の CDK スタックのグループを表します。ステージを使用し、開発、テスト、本番稼働などの複数の環境にスタックの同じグループをデプロイします。

CDK ステージを設定するには、Stage コンストラクトをインポートして使用します。

次の内容は、MyAppStage という名前の CDK ステージを定義する基本的な例です。AppStack および DatabaseStack という名前の 2 つの CDK スタックをステージに追加します。この例では、AppStack にはアプリケーションリソースが含まれており、DatabaseStack にはデータベースリソースが含まれています。次に、開発環境および本番環境用として MyAppStage の 2 つのインスタンスを作成します。
