AWS CLI Command Reference

[ aws . s3api ]

put-bucket-policy

Description

Applies an Amazon S3 bucket policy to an Amazon S3 bucket.

Note

Directory buckets - For directory buckets, you must make requests for this API operation to the Regional endpoint. These endpoints support path-style requests in the format ``https://s3express-control.*region_code* .amazonaws.com/bucket-name `` . Virtual-hosted-style requests aren’t supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide .

Permissions

If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must both have the PutBucketPolicy permissions on the specified bucket and belong to the bucket owner’s account in order to use this operation.

If you don’t have PutBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you’re not using an identity that belongs to the bucket owner’s account, Amazon S3 returns a 405 Method Not Allowed error.

Warning

To ensure that bucket owners don’t inadvertently lock themselves out of their own buckets, the root principal in a bucket owner’s Amazon Web Services account can perform the GetBucketPolicy , PutBucketPolicy , and DeleteBucketPolicy API actions, even if their bucket policy explicitly denies the root principal’s access. Bucket owner root principals can only be blocked from performing these API actions by VPC endpoint policies and Amazon Web Services Organizations policies.

  • General purpose bucket permissions - The s3:PutBucketPolicy permission is required in a policy. For more information about general purpose buckets bucket policies, see Using Bucket Policies and User Policies in the Amazon S3 User Guide .

  • Directory bucket permissions - To grant access to this API operation, you must have the s3express:PutBucketPolicy permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn’t supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide .

    Example bucket policies

Options

--bucket (string)

The name of the bucket.

Directory buckets - When you use this operation with a directory bucket, you must use path-style requests in the format https://s3express-control.*region_code* .amazonaws.com/*bucket-name* `` . Virtual-hosted-style requests aren't supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must also follow the format `` *bucket_base_name* --*az_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

--content-md5 (string)

The MD5 hash of the request body.

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

Note

This functionality is not supported for directory buckets.

--checksum-algorithm (string)

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-*algorithm* `` or ``x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request .

For the ``x-amz-checksum-algorithm `` header, replace `` algorithm `` with the supported algorithm from the following list:

  • CRC32
  • CRC32C
  • SHA1
  • SHA256

For more information, see Checking object integrity in the Amazon S3 User Guide .

If the individual checksum value you provide through x-amz-checksum-*algorithm* `` doesn't match the checksum algorithm you set through ``x-amz-sdk-checksum-algorithm , Amazon S3 ignores any provided ChecksumAlgorithm parameter and uses the checksum algorithm that matches the provided value in ``x-amz-checksum-algorithm `` .

Note

For directory buckets, when you use Amazon Web Services SDKs, CRC32 is the default checksum algorithm that’s used for performance.

Possible values:

  • CRC32
  • CRC32C
  • SHA1
  • SHA256

--confirm-remove-self-bucket-access | --no-confirm-remove-self-bucket-access (boolean)

Set this parameter to true to confirm that you want to remove your permissions to change this bucket policy in the future.

Note

This functionality is not supported for directory buckets.

--policy (string)

The bucket policy as a JSON document.

For directory buckets, the only IAM action supported in the bucket policy is s3express:CreateSession .

--expected-bucket-owner (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).

Note

For directory buckets, this header is not supported in this API operation. If you specify this header, the request fails with the HTTP status code 501 Not Implemented .

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

This example allows all users to retrieve any object in MyBucket except those in the MySecretFolder. It also grants put and delete permission to the root user of the AWS account 1234-5678-9012:

aws s3api put-bucket-policy --bucket MyBucket --policy file://policy.json

policy.json:
{
   "Statement": [
      {
         "Effect": "Allow",
         "Principal": "*",
         "Action": "s3:GetObject",
         "Resource": "arn:aws:s3:::MyBucket/*"
      },
      {
         "Effect": "Deny",
         "Principal": "*",
         "Action": "s3:GetObject",
         "Resource": "arn:aws:s3:::MyBucket/MySecretFolder/*"
      },
      {
         "Effect": "Allow",
         "Principal": {
            "AWS": "arn:aws:iam::123456789012:root"
         },
         "Action": [
            "s3:DeleteObject",
            "s3:PutObject"
         ],
         "Resource": "arn:aws:s3:::MyBucket/*"
      }
   ]
}
