PUT Bucket¶
You can send the PUT Bucket request to create a bucket with the specified name.
Note
You can create a maximum of 100 buckets.
You can enable WORM when you create a bucket, but you cannot enable WORM for an existing bucket. In a bucket with WORM enabled, you can further configure retention policies for objects you upload to this bucket. For more information, see Configuring a Default WORM Policy for a Bucket. Once enabled, WORM cannot be disabled for a bucket. When you create a bucket with WORM enabled, OBS automatically enables versioning for the bucket and the versioning cannot be suspended for that bucket. When you create a parallel file system, you cannot enable WORM for it.
The name of a bucket must be unique in OBS. If a user repeatedly creates namesake buckets in the same region, status code 200 is returned. If namesake buckets are repeatedly created in other cases, status code 409 is returned. You can set the ACL of a bucket by adding optional header x-amz-acl to a request.
Note
In multiple regions scenarios, if user A creates a bucket, deletes the bucket later, and immediately creates a bucket with the same name in different regions, the system will respond 409. If user A creates a bucket with the same name in different regions 30 minutes later, the system will respond 200.
If a 5xx error is returned from the server or the request times out during bucket creation, the system takes about 10 minutes to make bucket information consistent. During the process, bucket information is inaccurate.
Storage Class¶
Users are allowed to create buckets of different storage classes. The x-default-storage-class header in a bucket creation request specifies the default storage class for a bucket. The storage class of the objects in a bucket is the same as that of the bucket. There are three storage classes: STANDARD (OBS Standard), STANDARD_IA (OBS Warm), and GLACIER (OBS Cold). If this header is not in the request, the storage class of the bucket created is OBS Standard. When users upload an object to a bucket, if they do not set the storage class of the object (see PUT Object), the object will use the default storage class of the bucket.

Request Headers¶
This request uses common headers. For details about common request headers, see section Common Request Headers.
You can add optional headers to this request. Table 1 describes the optional headers.
Header | Description | Remarks |

x-default-storage-class | When creating a bucket, you can add this header in the request to set the bucket's default storage class, which can be STANDARD (OBS Standard), STANDARD_IA (OBS Warm), and GLACIER (OBS Cold). If this header is not specified in the request, the storage class of the bucket created is OBS Standard. Type: String | Optional |
x-amz-security-token | Header field used to identify the request of a federated user. When the federal authentication function is enabled, users sending such requests are identified as federated users. Type: string | Optional. This parameter must be carried in the request sent by federated users. |
x-amz-bucket-object-lock-enabled | When creating a bucket, you can use this header to enable WORM for the bucket. Type: string Example: x-amz-bucket-object-lock-enabled:true | No |
