Listing Buckets

You can list all created buckets to view their information.

Important Notes

Bucket listing requests default to the CN North-Beijing1 region. Therefore, the costs for the ListAllMyBucketsOperation requests are billed to this region.

Ways to List Buckets

You can use OBS Console, APIs, SDKs, OBS Browser+, or obsutil to list buckets.

Using OBS Console

  1. Log in to OBS Console.
  2. Go to the bucket list page, which displays all buckets under your account.

Parameter Description

Parameter

Optional or Mandatory

Description

s

Optional (additional parameter)

Displays simplified query result.

NOTE:

In the simplified format, the returned result contains only the bucket name.

sc

Optional (additional parameter)

Queries the storage classes of the buckets when listing buckets.

j

Optional (additional parameter). It must be used together with sc.

The maximum number of concurrent tasks for querying the bucket storage class. The default value is the value of defaultJobs in the configuration file.

NOTE:

The value is ensured to be greater than or equal to 1.

du

Optional (additional parameter)

Quickly returns the total size of listed objects, without displaying detailed object information. This parameter can be used together with other parameters.

NOTE:

This parameter takes effect only on listing objects, but not on listing buckets.

fs

Optional (additional parameter)

Whether the method of listing parallel file systems is applied. If you are listing parallel file systems, you are recommended to add this parameter.

CAUTION:
  • With this method, the listing time required varies largely depending on the directory structures.
  • After this parameter is enabled, marker and limit will be ignored. Then, the size of the bucket, parallel file system, or directory will be calculated.
  • This parameter is only supported by obsutil 5.5.12 and later.

limit

Optional (additional parameter)

The maximum number of buckets that can be queried. If the value is less than 0, all buckets are listed. If it is left blank, a maximum of 1000 buckets can be listed by default.

format

Optional (additional parameter)

Prints a listing result in the user-defined format. Currently, the value can only be default, indicating that the listing result is displayed in one row.

config

Optional (additional parameter)

The user-defined configuration file for executing the current command. For details about parameters that can be configured, see Configuration Parameters.

e

Optional (additional parameter)

The endpoint

i

Optional (additional parameter)

The user's AK

k

Optional (additional parameter)

The user's SK

t

Optional (additional parameter)

The user's security token

In a bucket listing result, BucketType indicates the bucket type. OBJECT indicates an object storage bucket, while POSIX indicates a parallel file system.
