S3 / Client / delete_object

delete_object#

S3.Client.delete_object(**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

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-zone-id.region-code.amazonaws.com.

The following action is related to DeleteObject:

See also: AWS API Documentation

Request Syntax

response = client.delete_object(
    Bucket='string',
    Key='string',
    MFA='string',
    VersionId='string',
    RequestPayer='requester',
    BypassGovernanceRetention=True|False,
    ExpectedBucketOwner='string',
    IfMatch='string',
    IfMatchLastModifiedTime=datetime(2015, 1, 1),
    IfMatchSize=123
)
Parameters:

  • Bucket (string) –

    [REQUIRED]

    The bucket name of the bucket containing the object.

    Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket-name.s3express-zone-id.region-code.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Zone (Availability Zone or Local Zone). Bucket names must follow the format bucket-base-name--zone-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.

    Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.*Region*.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.

    Note

    Access points and Object Lambda access points are not supported by directory buckets.

    S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.

  • Key (string) –

    [REQUIRED]

    Key name of the object to delete.

  • 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.

  • VersionId (string) –

    Version ID used to reference a specific version of the object.

    Note

    For directory buckets in this API operation, only the null value of the version ID is supported.

  • 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).

  • IfMatch (string) –

    The If-Match header field makes the request method conditional on ETags. If the ETag value does not match, the operation returns a 412 Precondition Failed error. If the ETag matches or if the object doesn’t exist, the operation will return a 204 Success (No Content) response.

    For more information about conditional requests, see RFC 7232.

    Note

    This functionality is only supported for directory buckets.

  • IfMatchLastModifiedTime (datetime) –

    If present, the object is deleted only if its modification times matches the provided Timestamp. If the Timestamp values do not match, the operation returns a 412 Precondition Failed error. If the Timestamp matches or if the object doesn’t exist, the operation returns a 204 Success (No Content) response.

    Note

    This functionality is only supported for directory buckets.

  • IfMatchSize (integer) –

    If present, the object is deleted only if its size matches the provided size in bytes. If the Size value does not match, the operation returns a 412 Precondition Failed error. If the Size matches or if the object doesn’t exist, the operation returns a 204 Success (No Content) response.

    Note

    This functionality is only supported for directory buckets.

    Warning

    You can use the If-Match, x-amz-if-match-last-modified-time and x-amz-if-match-size conditional headers in conjunction with each-other or individually.
