A Bucket in TOS is a globally unique namespace that serves as a container for storing Object data. The name of a newly created bucket must be unique within TOS. This article explains how to create a bucket.
Precautions
- Bucket naming conventions are as follows:
- Only lowercase letters (a–z), digits, and hyphens (-) are permitted.
- The beginning and end can only be a digit or a letter.
- The length must be between 3 and 63 characters.
- When accessing TOS via other Volcano Engine products in the same region as TOS, it is recommended to use the internal network Endpoint. For more information about regions and Endpoints, please refer to Regions and Access Endpoints.
- Before creating a storage bucket, you must ensure that your account has the tos:CreateBucket permission. You can grant the corresponding permissions through IAM policies. For detailed steps, please refer to IAM policies.
Sample Code
Specify the ACL when creating a bucket.
