Object Storage Service:バケット在庫

使用上の注意

• このトピックでは、中国 (杭州) リージョンのパブリックエンドポイントを使用します。 OSSと同じリージョンにある他のAlibaba CloudサービスからOSSにアクセスする場合は、内部エンドポイントを使用します。 OSSリージョンとエンドポイントの詳細については、「リージョン、エンドポイント、オープンポート」をご参照ください。

• このトピックでは、アクセス資格情報は環境変数から取得します。 アクセス資格情報の設定方法の詳細については、「アクセス資格情報の設定」をご参照ください。

• このトピックでは、OSSエンドポイントを使用してOSSClientインスタンスを作成します。 カスタムドメイン名またはSecurity Token Service (STS) を使用してOSSClientインスタンスを作成する場合は、「OSSClientインスタンスの作成」をご参照ください。

• バケットのインベントリを作成、表示、一覧表示、および削除する権限があることを確認します。 デフォルトでは、バケット所有者に上記の操作を実行する権限があります。 上記の操作を実行する権限がない場合は、バケットの所有者に権限を付与するよう依頼してください。

• バケットには最大1,000のインベントリを設定できます。

• インベントリを構成するソースバケットは、インベントリリストが保存されているターゲットバケットと同じリージョンにデプロイする必要があります。
