Creating a Bucket

This section describes how to create a bucket in OBS Console. 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. In the upper right corner of the OBS Console, click Create BucketFigure 1 displays Create Bucket dialog box.

    Figure 1 Creating a bucket

  2. Set Region and Storage Class, and then enter a name for the bucket.

    • Once you create a bucket, you cannot change the name of it. Make sure that the bucket name you set is appropriate.
    • 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.

  3. You can configure any of the general policies for a bucket. The general policies include private, public read, and public read and write. Alternatively, you can set these properties after creating the bucket. For more information, see Configuring a Bucket Policy.
  4. Tags: Tags are used to identify and classify OBS buckets. Each tag is represented by one key-value pair. For more information, see Tags.
