Put Bucket Acl

s3_put_bucket_acl R Documentation

This operation is not supported by directory buckets

Description

This operation is not supported by directory buckets.

Sets the permissions on an existing bucket using access control lists (ACL). For more information, see Using ACLs. To set the ACL of a bucket, you must have the WRITE_ACP permission.

You can use one of the following two ways to set a bucket's permissions:

  • Specify the ACL in the request body

  • Specify permissions using request headers

You cannot specify access permission using both the body and the request headers.

Depending on your application needs, you may choose to set the ACL on a bucket using either the request body or the headers. For example, if you have an existing application that updates a bucket ACL using the request body, then you can continue to use that approach.

If your bucket uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. You must use policies to grant access to your bucket and the objects in it. Requests to set ACLs or update ACLs fail and return the AccessControlListNotSupported error code. Requests to read ACLs are still supported. For more information, see Controlling object ownership in the Amazon S3 User Guide.

Permissions

You can set access permissions by using one of the following methods:

  • Specify a canned ACL with the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. Specify the canned ACL name as the value of x-amz-acl. If you use this header, you cannot use other access control-specific headers in your request. For more information, see Canned ACL.

  • Specify access permissions explicitly with the x-amz-grant-read, x-amz-grant-read-acp, x-amz-grant-write-acp, and x-amz-grant-full-control headers. When using these headers, you specify explicit access permissions and grantees (Amazon Web Services accounts or Amazon S3 groups) who will receive the permission. If you use these ACL-specific headers, you cannot use the x-amz-acl header to set a canned ACL. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview.

    You specify each grantee as a type=value pair, where the type is one of the following:

    • id – if the value specified is the canonical user ID of an Amazon Web Services account

    • uri – if you are granting permissions to a predefined group

    • emailAddress – if the value specified is the email address of an Amazon Web Services account

      Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

      • US East (N. Virginia)

      • US West (N. California)

      • US West (Oregon)

      • Asia Pacific (Singapore)

      • Asia Pacific (Sydney)

      • Asia Pacific (Tokyo)

      • Europe (Ireland)

      • South America (São Paulo)

      For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

    For example, the following x-amz-grant-write header grants create, overwrite, and delete objects permission to LogDelivery group predefined by Amazon S3 and two Amazon Web Services accounts identified by their email addresses.

    ⁠x-amz-grant-write: uri="http://acs.amazonaws.com/groups/s3/LogDelivery", id="111122223333", id="555566667777" ⁠

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Grantee Values

You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:

  • By the person's ID:

    ⁠<Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee>⁠

    DisplayName is optional and ignored in the request

  • By URI:

    ⁠<Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee>⁠

  • By Email address:

    ⁠<Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grantees@email.com<></EmailAddress>&</Grantee>⁠

    The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)

    • US West (N. California)

    • US West (Oregon)

    • Asia Pacific (Singapore)

    • Asia Pacific (Sydney)

    • Asia Pacific (Tokyo)

    • Europe (Ireland)

    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

Usage

s3_put_bucket_acl(ACL, AccessControlPolicy, Bucket, ContentMD5,
  ChecksumAlgorithm, GrantFullControl, GrantRead, GrantReadACP,
  GrantWrite, GrantWriteACP, ExpectedBucketOwner)

Arguments

ACL

The canned ACL to apply to the bucket.

AccessControlPolicy

Contains the elements that set the ACL permissions for an object per grantee.

Bucket

[required] The bucket to which to apply the ACL.

ContentMD5

The base64-encoded 128-bit MD5 digest of the data. This header must be used as a message integrity check to verify that the request body was not corrupted in transit. For more information, go to RFC 1864.

For requests made using the Amazon Web Services Command Line Interface (CLI) or Amazon Web Services SDKs, this field is calculated automatically.

ChecksumAlgorithm

Indicates the algorithm used to create the checksum for the object when you use the SDK. This header will not provide any additional functionality if you don't use the SDK. When you send this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code ⁠400 Bad Request⁠. For more information, see Checking object integrity in the Amazon S3 User Guide.

If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

GrantFullControl

Allows grantee the read, write, read ACP, and write ACP permissions on the bucket.

GrantRead

Allows grantee to list the objects in the bucket.

GrantReadACP

Allows grantee to read the bucket ACL.

GrantWrite

Allows grantee to create new objects in the bucket.

For the bucket and object owners of existing objects, also allows deletions and overwrites of those objects.

GrantWriteACP

Allows grantee to write the ACL for the applicable bucket.

ExpectedBucketOwner

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).

Value

An empty list.

Examples

## Not run: 
# The following example replaces existing ACL on a bucket. The ACL grants
# the bucket owner (specified using the owner ID) and write permission to
# the LogDelivery group. Because this is a replace operation, you must
# specify all the grants in your request. To incrementally add or remove
# ACL grants, you might use the console.
svc$put_bucket_acl(
  Bucket = "examplebucket",
  GrantFullControl = "id=examplee7a2f25102679df27bb0ae12b3f85be6f290b936c4393484",
