[ aws . s3api ]



Creates a new bucket. To create a bucket, you must register with Amazon S3 and have a valid AWS Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner.

Not every string is an acceptable bucket name. For information on bucket naming restrictions, see Working with Amazon S3 Buckets .

By default, the bucket is created in the US East (N. Virginia) Region. You can optionally specify a Region in the request body. You might choose a Region to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you will probably find it advantageous to create buckets in the Europe (Ireland) Region. For more information, see How to Select a Region for Your Buckets .


If you send your create bucket request to the s3.amazonaws.com endpoint, the request goes to the us-east-1 Region. Accordingly, the signature calculations in Signature Version 4 must use us-east-1 as the Region, even if the location constraint in the request specifies another Region where the bucket is to be created. If you create a bucket in a Region other than US East (N. Virginia), your application must be able to handle 307 redirect. For more information, see Virtual Hosting of Buckets .

When creating a bucket using this operation, you can optionally specify the accounts or groups that should be granted specific permissions on the bucket. There are two ways to grant the appropriate permissions using the request headers.

  • Specify a canned ACL using 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. For more information, see Canned ACL .

  • Specify access permissions explicitly using the x-amz-grant-read , x-amz-grant-write , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. These headers map to the set of permissions 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


    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-read header grants the AWS accounts identified by account IDs permissions to read object data and its metadata:

x-amz-grant-read: id="11112222333", id="444455556666"


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

The following operations are related to CreateBucket :

  • PutObject

  • DeleteBucket

--acl (string)

The canned ACL to apply to the bucket.

Possible values:

  • private

  • public-read

  • public-read-write

  • authenticated-read

--bucket (string)

The name of the bucket to create.

--create-bucket-configuration (structure)

The configuration information for the bucket.

LocationConstraint -> (string)

Specifies the Region where the bucket will be created. If you don’t specify a Region, the bucket is created in the US East (N. Virginia) Region (us-east-1).

Shorthand Syntax:


JSON Syntax:

  "LocationConstraint": "EU"|"eu-west-1"|"us-west-1"|"us-west-2"|"ap-south-1"|"ap-southeast-1"|"ap-southeast-2"|"ap-northeast-1"|"sa-east-1"|"cn-north-1"|"eu-central-1"

--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.

--object-lock-enabled-for-bucket | --no-object-lock-enabled-for-bucket (boolean)

Specifies whether you want S3 Object Lock to be enabled for the new bucket.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


The following command creates a bucket named my-bucket:

aws s3api create-bucket --bucket my-bucket --region us-east-1


    "Location": "/my-bucket"

The following command creates a bucket named my-bucket in the eu-west-1 region. Regions outside of us-east-1 require the appropriate LocationConstraint to be specified in order to create the bucket in the desired region:

$ aws s3api create-bucket --bucket my-bucket --region eu-west-1 --create-bucket-configuration LocationConstraint=eu-west-1


    "Location": "http://my-bucket.s3.amazonaws.com/"


Location -> (string)

Specifies the Region where the bucket will be created. If you are creating a bucket on the US East (N. Virginia) Region (us-east-1), you do not need to specify the location.
