Creating a Bucket

Functions

This operation is used to create a bucket with a specified name.

  • By default, a user can have a maximum of 100 buckets.
  • The name of a deleted bucket can be reused for a bucket or a parallel file system at least 30 minutes after the deletion.
  • When creating a bucket in OBS, you can enable the multi-AZ mode for the bucket or disable it. With the multi-AZ mode disabled, data in a bucket is stored in a single AZ by default. With the multi-AZ mode enabled, data in a bucket is stored redundantly in multiple AZs, improving reliability. However, buckets created before are still in the single AZ mode.

A bucket name must be unique in OBS. If a user creates a bucket with the same name as that of an existing bucket under the same account and in the same region, a 200 code (indicating success) is returned. In scenarios other than the preceding one, the request for creating a bucket with the same name as that of an existing one will receive the 409 code (indicating that a namesake bucket already exists). To set an access control policy for the bucket to be created, you can add the x-obs-acl parameter to request headers.

Request Parameters

This request contains no parameters.

Request Headers

The operation message header is the same as that of a common request. For details, see Table 3. However, this request can contain additional headers. The following table describes the additional headers for this request.

Table 1 Additional request headers

Header

Description

Mandatory

x-obs-acl

When creating a bucket, you can add this header to set the permission control policy for the bucket. The predefined common policies are as follows: private, public-read, public-read-write, public-read-delivered, and public-read-write-delivered.

Type: string

No

x-obs-grant-read

This header grants the read permission to all users under an account. It allows you to list objects in a bucket, list multipart tasks in a bucket, list multi-version objects in a bucket, and obtain bucket metadata.

Type: string

Example: x-obs-grant-read:id=Tenant ID

No

x-obs-grant-write

This header grants the write permission to all users under an account. Therefore, the users can create, delete, and overwrite all objects in a bucket, and can initialize parts, upload parts, copy parts, merge parts, and cancel multipart upload tasks.

Type: string

Example: x-obs-grant-write:id=Tenant ID

No

x-obs-grant-read-acp

This header grants the ACL read permission to all users under an account. Therefore, the users can read the bucket ACL information.

Type: string

Example: x-obs-grant-read-acp:id=Account ID

No

x-obs-grant-write-acp

This header grants the ACL write permission to all users under an account. Therefore, the users can modify the ACL of the bucket.

Type: string

Example: x-obs-grant-write-acp:id=Account ID

No

x-obs-grant-full-control

This header grants the full control permission to all users under an account.

Type: string

Example: x-obs-grant-full-control:id=Account ID

No

x-obs-grant-read-delivered

This header grants the read permission to all users under an account. By default, the read permission is applied to all objects in the bucket.

Type: string

Example: x-obs-grant-read-delivered:id=Account ID

No

x-obs-grant-full-control-delivered

This header grants the full control permission to all users under an account. By default, the FULL_CONTROL permission is applied to all objects in the bucket.

Type: string

Example: x-obs-grant-full-control-delivered:id=Account ID

No

x-obs-az-redundancy

This header is carried in the request when creating a bucket to enable the multi-AZ mode for the bucket. If this header is not carried, the bucket is in the single AZ mode by default. This header is carried to specify that a newly created bucket uses multi-AZ storage. If the region where the bucket resides does not support multi-AZ storage, the bucket still uses the single-AZ storage.

Type: string

Example: x-obs-az-redundancy:3az

No

x-obs-fs-file-interface

This header can be carried when you create a bucket as a parallel file system.

Type: string

Example: x-obs-fs-file-interface:Enabled

No

Request Elements

This request can use additional elements. For details about additional elements, see Table 2.

Table 2 Additional request elements

Element

Description

Mandatory

Location

Specifies the region where a bucket will be created.

  • When creating a bucket using the endpoint of the default region, note the following:
    • If Location is not specified, the bucket is created in the default region.
    • If Location is specified to other region, the bucket is created in the specified region.
  • When creating a bucket using the endpoint of a non-default region, Location must be specified to the region corresponding to the endpoint.

Type: string
