Deleting a Bucket (SDK for Go)
Function
This API deletes an empty bucket. You can delete buckets you no longer use to free up space. The name of a deleted bucket can be reused for another bucket at least 30 minutes after the deletion.
![](https://support.huaweicloud.com/intl/en-us/sdk-go-devg-obs/public_sys-resources/note_3.0-en-us.png)
The data you deleted from OBS cannot be recovered on Huawei Cloud. Exercise caution when using this API.
Restrictions
- Only empty buckets can be deleted. An empty bucket means that:
- The bucket does not contain any object (including noncurrent versions and delete markers).
- The bucket does not contain any fragments, which means that there are no multipart uploads that have not been completed in the bucket.
- To delete a bucket, you must be the bucket owner or have the required permission (obs:bucket:DeleteBucket in IAM or DeleteBucket in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.
- The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.
