Creating Buckets

Last updated: 2021-11-19 14:44:28


    You can create a bucket on the Bucket List page in the COS console. For more information about buckets, please see Bucket Overview.


    Each account can create up to 200 buckets regardless of the region.


    1. Log in to the COS console.
    2. On the left sidebar, click Bucket List to enter the bucket list page, and then click Create Bucket.
    3. In the pop-up window, configure the following information:
      1. Basic information
    • Region: a COS region corresponding to the physical location where your business or users are distributed. This parameter cannot be modified once configured. For more information about regions, please see Regions and Access Endpoints.

    • Name: a custom bucket name, which cannot be modified once configured. For more information, please see Naming Conventions.

    • Access Permissions: Three access permissions are available for buckets by default: "Private Read/Write", "Public Read/Private Write", and "Public Read/Write". You can modify it if needed. For more information, please see Setting Access Permission.

    • Domain Name: The value is generated automatically. After creating a bucket, you can use this domain name to access the bucket.

      1. Advanced settings

        Advanced settings are optional and can be set as needed.

    • Versioning: If this field is enabled, and you upload an object whose name already exists, the historical version will be retained.

    • Logging: stores logs of bucket-related requests.

    • Bucket Tag: A tag is used as an identifier to manage buckets. For more information, please see Setting Bucket Tags.

    • Server-Side Encryption: Currently, the only supported bucket encryption method is SSE-COS encryption (i.e., server encryption using COS-managed keys). For more information on server encryption, see Server Encryption Overview.

      1. Configuration confirmation

    Confirm the bucket configurations. If there is anything you need to modify, click Previous and modify as needed.
    4. Verify the information entered and then click OK to create the bucket. You will then be able to view the created bucket on the Bucket List page.
