バケットへの指定された通知を有効にするには

次のput-bucket-notification-configuration例では、 という名前のバケットに通知設定を適用しますmy-bucketnotification.json ファイルは、現在のフォルダ内の JSON ドキュメントで、モニタリングする SNS トピックとイベントタイプを指定します。

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

notification.json の内容:

{ "TopicConfigurations": [ { "TopicArn": "arn:aws:sns:us-west-2:123456789012:s3-notification-topic", "Events": [ "s3:ObjectCreated:*" ] } ] }

SNS トピックには、Amazon S3 がトピックに発行することを許可する IAM ポリシーがアタッチされている必要があります。

{ "Version": "2008-10-17", "Id": "example-ID", "Statement": [ { "Sid": "example-statement-ID", "Effect": "Allow", "Principal": { "Service": "s3.amazonaws.com" }, "Action": [ "SNS:Publish" ], "Resource": "arn:aws:sns:us-west-2:123456789012::s3-notification-topic", "Condition": { "ArnLike": { "aws:SourceArn": "arn:aws:s3:*:*:my-bucket" } } } ] }
