Per abilitare le notifiche specificate in un bucket

L'put-bucket-notification-configurationesempio seguente applica una configurazione di notifica a un bucket denominato. my-bucket Il file notification.json è un JSON documento nella cartella corrente che specifica un SNS argomento e un tipo di evento da monitorare.

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

Contenuto di notification.json.

All'SNSargomento deve essere associata una IAM policy che consenta ad Amazon S3 di pubblicare su di esso.
