Creating a Bucket

Last updated: 2022-04-29 11:17:43


    You can create a bucket on the Bucket List page in the COS console. For more information about buckets, 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 field cannot be modified once configured. For more information about regions, see Regions and Access Endpoints.
      • Name: A custom bucket name, which cannot be modified once configured. For more information, see Naming Conventions.
      • Access Permission: 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, see Setting Access Permission.
      • Endpoint: The value is generated automatically. After creating a bucket, you can use this endpoint 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, 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.
    1. Confirm the information and then click Create to create the bucket. You will then be able to view the created bucket on the Bucket List page.
