Creating Buckets

Last updated: 2019-09-23 16:09:24



You can create buckets on the Bucket List page on the COS Console. For more information on buckets, see Bucket Overview.

A maximum of 200 buckets can be created under a single account regardless of region.


  1. Log in to the COS Console.
  2. On the left sidebar, click Bucket List to enter the bucket list, and then click Create Bucket.
  3. In the Create Bucket dialog box, configure the information as follows:
    • Name: Enter a custom bucket name, which is non-modifiable once being configured. For information on naming, see Naming Conventions.
    • Region: Select the COS region where your business is operated mostly or most of your users reside. It is non-modifiable once being configured. For more information on regions, see Regions and Endpoints.
    • Access Permission: Three access permissions for buckets are available by default: "Private Read/Write", "Public Read/Private Write" and "Public Read/Write". The permission is modifiable after being configured. For more information, see Bucket Access Permissions.
    • Bucket Tag: Bucket tags are used to identify and group buckets for an easier management. For more information, see Setting Bucket Tags.
  4. Verify that all the information entered is correct, and then click OK to create a bucket. In the Bucket List page, you can see the bucket you just created.
