put-bucket-acl

Description

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 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

Note

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.

Access Permissions

You can set access permissions 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 (AWS 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 AWS account

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

  • emailAddress – if the value specified is the email address of an AWS account

  Note

  Using email addresses to specify a grantee is only supported in the following AWS 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 AWS 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 AWS 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>lt;/Grantee> The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.

Note

Using email addresses to specify a grantee is only supported in the following AWS 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 AWS General Reference.

}

--bucket (string)

The bucket to which to apply the ACL.

--content-md5 (string)

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 AWS Command Line Interface (CLI) or AWS SDKs, this field is calculated automatically.

--grant-full-control (string)

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

--grant-read (string)

Allows grantee to list the objects in the bucket.

--grant-read-acp (string)

Allows grantee to read the bucket ACL.

--grant-write (string)

Allows grantee to create, overwrite, and delete any object in the bucket.

--grant-write-acp (string)

Allows grantee to write the ACL for the applicable bucket.

--expected-bucket-owner (string)

The account id of the expected bucket owner. If the bucket is owned by a different account, the request will fail with an HTTP 403 (Access Denied) error.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples

This example grants full control to two AWS users (user1@example.com and user2@example.com) and read permission to everyone:

aws s3api put-bucket-acl --bucket MyBucket --grant-full-control emailaddress=user1@example.com,emailaddress=user2@example.com --grant-read uri=http://acs.amazonaws.com/groups/global/AllUsers

See http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketPUTacl.html for details on custom ACLs (the s3api ACL commands, such as put-bucket-acl, use the same shorthand argument notation).

Output

None
