CLI

Esempio 1: creare un bucket

L'create-bucketesempio seguente crea un bucket denominato: my-bucket

aws s3api create-bucket \ --bucket my-bucket \ --region us-east-1

Output:

{ "Location": "/my-bucket" }

Per ulteriori informazioni, consulta Creare un bucket nella Guida per l'utente di Amazon S3.

Esempio 2: creare un bucket con il proprietario imposto

L'create-bucketesempio seguente crea un bucket denominato my-bucket che utilizza l'impostazione bucket owner enforced per S3 Object Ownership.

aws s3api create-bucket \ --bucket my-bucket \ --region us-east-1 \ --object-ownership BucketOwnerEnforced

Output:

{ "Location": "/my-bucket" }

Per ulteriori informazioni, consulta la sezione Controllo della proprietà degli oggetti e disattivazione ACLs nella Guida per l'utente di Amazon S3.

Esempio 3: creare un bucket al di fuori della regione ``us-east-1``

L'create-bucketesempio seguente crea un bucket denominato nella regione. my-bucket eu-west-1 Le aree esterne LocationConstraint a us-east-1 richiedono che venga specificato il valore appropriato per creare il bucket nella regione desiderata.

aws s3api create-bucket \ --bucket my-bucket \ --region eu-west-1 \ --create-bucket-configuration LocationConstraint=eu-west-1

Output:

{ "Location": "http://my-bucket.s3.amazonaws.com/" }
