AWS SDK または CLI で PutBucketLifecycleConfiguration を使用する

        /// <summary>

        /// the bucketName parameter.
        /// </summary>

        /// PutLifecycleConfigurationAsync method.</param>

        public static async Task AddExampleLifecycleConfigAsync(IAmazonS3 client, string bucketName, LifecycleConfiguration configuration)
        {
            var request = new PutLifecycleConfigurationRequest()

次のコマンドは、my-bucket という名前のバケットにライフサイクル設定を適用します。

aws s3api put-bucket-lifecycle-configuration --bucket my-bucket --lifecycle-configuration  file://lifecycle.json

lifecycle.json ファイルは、現在のフォルダ内の JSON ドキュメントで、次の 2 つのルールを指定します。

{
    "Rules": [
        {
            "ID": "Move rotated logs to Glacier",
            "Prefix": "rotated/",
            "Status": "Enabled",
            "Transitions": [
                {
                    "Date": "2015-11-10T00:00:00.000Z",
                    "StorageClass": "GLACIER"
                }
            ]
        },
        {
            "Status": "Enabled",
            "Prefix": "",
            "NoncurrentVersionTransitions": [
                {
                    "NoncurrentDays": 2,
                    "StorageClass": "GLACIER"
                }
            ],
            "ID": "Move old versions to Glacier"
        }
    ]
}

1 つ目のルールは、指定した日付に、プレフィックス rotated の付いたファイルを Glacier に移動します。2 つ目のルールは、最新でない古いオブジェクトバージョンを Glacier に移動します。詳細については、「AWS CLI ユーザーガイド」の「Specifying Parameter Values」を参照してください。
