Adding a Bucket

On OBS, buckets are containers where objects are stored. Before you store data in OBS, you need to create buckets.


An account can create 100 buckets.


  1. Log in to OBS Browser.
  2. In the upper left corner on the page, click Add Bucket.
  3. In the Add Bucket dialog box, displayed in Figure 1, select Create new bucket for Method.

  4. Set Region to the name of the region where the bucket will reside. For details about regions, see Region Information Configuration
  5. Select the Storage Class according to your actual needs.
  6. Enter a name in the text box of Bucket Name.

    You can move the pointer over  behind the Bucket Name text box to view the naming rules for a bucket.

    • When a URL is used to access a bucket, the bucket name will become a part of the URL. According to the DNS rule, URLs do not support uppercase letters and cannot be used to access a bucket whose name contains uppercase letters. Therefore, a bucket name can contain only lowercase letters, digits, hyphens (-), and periods (.) For example, if you attempt to access bucket MyBucket using the URL, bucket mybucket will be accessed instead, causing an access error.
    • DNS naming can standardize the bucket naming globally, facilitating the resolution when accessing a bucket. Users can benefit from new functions and optimized features, and static website hosting is then applicable to buckets.
