Amazon Elastic File System サンプルテンプレート

Amazon Elastic File System (Amazon EFS) は、Amazon Elastic Compute Cloud (Amazon EC2) インスタンスのファイルストレージサービスです。Amazon EFS を使用すると、ファイルの追加および削除に合わせてストレージ容量が自動的に拡大/縮小するため、アプリケーションには必要なときにストレージが提供されます。

以下のサンプルテンプレートは、Amazon EFS ファイルシステムに関連付けられる EC2 インスタンス (Auto Scaling グループ内) をデプロイします。ファイルシステムにインスタンスを関連付けるために、インスタンスは cfn-init ヘルパースクリプトを実行します。これにより、nfs-utils yum パッケージがダウンロードおよびインストールされて、新しいディレクトリが作成され、ファイルシステムの DNS 名を使用してそのディレクトリにファイルシステムがマウントされます。ファイルシステムの DNS 名は、Amazon EC2 インスタンスのアベイラビリティーゾーンでマウントターゲットの IP アドレスに解決されます。DNS 名構造については、Amazon Elastic File System ユーザーガイドの「ファイルシステムのマウント」を参照してください。

Network File System (NFS) のアクティビティを測定するために、テンプレートにはカスタムの Amazon CloudWatch メトリクスが含まれています。このテンプレートでは、VPC、サブネット、およびセキュリティグループも作成します。インスタンスとファイルシステムとの通信を許可するには、VPC で DNS が有効になっていて、マウントターゲットと EC2 インスタンスはサブネットに指定された同じアベイラビリティーゾーン (AZ) にある必要があります。

マウントターゲットのセキュリティグループは TCP ポート 2049 へのネットワーク接続を有効にします。これは、NFSv4 クライアントがファイルシステムをマウントするために必要です。EC2 インスタンスとマウントターゲット向けのセキュリティグループの詳細については、Amazon Elastic File System ユーザーガイドの「セキュリティ」を参照してください。

注記

置き換えの原因となる更新をマウントターゲットに対して行った場合は、関連するファイルシステムを使用するインスタンスまたはアプリケーションが中断される可能性があります。このため、コミットされていない書き込みが失われることがあります。中断を回避するには、希望する容量をゼロに設定することで、マウントターゲットの更新時にインスタンスを停止します。これにより、マウントターゲットを削除する前に、インスタンスがファイルシステムをアンマウントできるようになります。マウントの更新が完了したら、希望する容量を設定して後続の更新のインスタンスを開始します。
