Creating Bucket

Last updated: 2024-06-03 10:51:47

Overview
You can create a bucket on the bucket list page through the Cloud Object Storage (COS) console. For the concept of buckets, see Bucket Overview. Below, we will detail how to create a bucket.
Note:
Each account can create up to 200 buckets regardless of the region.
Directions
1. Log in to the COS console.
2. In the left navigation pane, click Bucket List to enter the bucket list page.
3. Click Create Bucket.
4. In the Create Bucket dialog box that is displayed, configure the following information:
4.1 Basic information
Region: Choose a COS region corresponding to the physical area where your business (or user base) is concentrated. Once set, this cannot be modified. For more information about regions, see Regions and Access Endpoints.
Name: Enter a custom bucket name. Once set, this cannot be modified. For naming guidelines, see Bucket Naming Conventions.
Access Permission: By default, a bucket provides three types of access permissions: private read/write, public read/private write, and public read/write. This can be modified after setting. For more information, see Setting Access Permissions.
Endpoint: Automatically generated. After creating a bucket, you can use this domain name to access the bucket.
4.2 Advanced optional configuration
Note:
Advanced settings are optional and can be set as needed.
Versioning: After enabling, uploading an object with the same name or performing operations such as adding, deleting, or modifying objects will save historical versions, facilitating the retrieval of an object's historical versions.
Note:
If versioning and MAZ features are enabled at the same time, the status of versioning cannot be modified. Configure with caution.
MAZ configuration: The MAZ feature is a characteristic of the bucket. When you enable the MAZ configuration, your data will be stored in different data centers within the same region, providing intra-city disaster recovery. Currently, this feature is only available in certain regions, such as Beijing, Shanghai, Guangzhou, Hong Kong (China), and Singapore. For more applicable regions and feature introduction, see MAZ Feature Overview.
Note:
Once the MAZ configuration for a bucket is enabled, it cannot be modified. After enabling, data will be stored in the bucket in storage types that support the MAZ feature (for example, MAZ_STANDARD and MAZ_STANDARD_IA). Configure with caution. If versioning is also enabled, the status of versioning cannot be modified.
MAZ configuration cannot be enabled for existing buckets. It can be enabled only for new buckets during creation.
Metadata Acceleration: This configuration is currently only available to allowlisted users. For more information, see Metadata Acceleration Overview.
Logging: Records various request logs related to bucket operations for you.
Bucket Tag: A bucket tag serves as an identifier for managing buckets. You can set tags for your buckets to facilitate grouped management. For more information, see Setting Bucket Tags.
Server-Side Encryption: You can choose a server-side encryption method. For an introduction to server-side encryption and supported regions, see Server-Side Encryption Overview.
4.3 Confirm configuration
Confirm the bucket configuration information. If you need to make changes, click Previous.
5. After confirming the information is correct, click Create to create the bucket. On the bucket list page, you can see the bucket you just created.

Note:
The bucket list will only display the buckets you created with Data Lake Compute (DLC) and does not support configuration for now. If you need to configure, go to the DLC console to proceed.
