ObjectVersion / Action / delete

delete#

S3.ObjectVersion.delete(**kwargs)#

Removes an object from a bucket. The behavior depends on the bucket’s versioning state:

  • If bucket versioning is not enabled, the operation permanently deletes the object.

  • If bucket versioning is enabled, the operation inserts a delete marker, which becomes the current version of the object. To permanently delete an object in a versioned bucket, you must include the object’s versionId in the request. For more information about versioning-enabled buckets, see Deleting object versions from a versioning-enabled bucket.

  • If bucket versioning is suspended, the operation removes the object that has a null versionId, if there is one, and inserts a delete marker that becomes the current version of the object. If there isn’t an object with a null versionId, and all versions of the object have a versionId, Amazon S3 does not remove the object and only inserts a delete marker. To permanently delete an object that has a versionId, you must include the object’s versionId in the request. For more information about versioning-suspended buckets, see Deleting objects from versioning-suspended buckets.

Note

  • Directory buckets - S3 Versioning isn’t enabled and supported for directory buckets. For this API operation, only the null value of the version ID is supported by directory buckets. You can only specify null to the versionId query parameter in the request.

  • Directory buckets - For directory buckets, you must make requests for this API operation to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format ``https://bucket_name.s3express-az_id.region.amazonaws.com/key-name ``. Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

To remove a specific version, you must use the versionId query parameter. Using this query parameter permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header x-amz-delete-marker to true.

If the object you want to delete is in a bucket where the bucket versioning configuration is MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS. For more information about MFA Delete, see Using MFA Delete in the Amazon S3 User Guide. To see sample requests that use versioning, see Sample Request.

Note

Directory buckets - MFA delete is not supported by directory buckets.

You can delete objects by explicitly calling DELETE Object or calling ( PutBucketLifecycle) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject, s3:DeleteObjectVersion, and s3:PutLifeCycleConfiguration actions.

Note

Directory buckets - S3 Lifecycle is not supported by directory buckets.

Permissions

  • General purpose bucket permissions - The following permissions are required in your policies when your DeleteObjects request includes specific headers.

    • s3:DeleteObject - To delete an object from a bucket, you must always have the s3:DeleteObject permission.

    • s3:DeleteObjectVersion - To delete a specific version of an object from a versioning-enabled bucket, you must have the s3:DeleteObjectVersion permission.

  • Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

    HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

Request Syntax

response = object_version.delete(
    MFA='string',
    RequestPayer='requester',
    BypassGovernanceRetention=True|False,
    ExpectedBucketOwner='string'
)
Parameters:

  • MFA (string) –

    The concatenation of the authentication device’s serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.

    Note

    This functionality is not supported for directory buckets.

  • RequestPayer (string) –

    Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

    Note

    This functionality is not supported for directory buckets.

  • BypassGovernanceRetention (boolean) –

    Indicates whether S3 Object Lock should bypass Governance-mode restrictions to process this operation. To use this header, you must have the s3:BypassGovernanceRetention permission.

    Note

    This functionality is not supported for directory buckets.

  • ExpectedBucketOwner (string) – The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

Return type:

dict

Returns:

Response Syntax

{
    'DeleteMarker': True|False,
    'VersionId': 'string',
    'RequestCharged': 'requester'
}

Response Structure

  • (dict) –

    • DeleteMarker (boolean) –

      Indicates whether the specified object version that was permanently deleted was (true) or was not (false) a delete marker before deletion. In a simple DELETE, this header indicates whether (true) or not (false) the current version of the object is a delete marker.

      Note

      This functionality is not supported for directory buckets.

    • VersionId (string) –

      Returns the version ID of the delete marker created as a result of the DELETE operation.

      Note

      This functionality is not supported for directory buckets.

    • RequestCharged (string) –

      If present, indicates that the requester was successfully charged for the request.

      Note

      This functionality is not supported for directory buckets.
