Delete a bucket (Go SDK V1)-Object Storage Service(OSS)-阿里云帮助中心

If you no longer need a bucket, you can delete it to stop all billing. Because Object Storage Service (OSS) fees are charged for the resources inside a bucket, you must clear all resources before deleting it. Deleting a bucket is the most reliable way to prevent unexpected fees from overlooked billable resources. Note that data cannot be recovered after a bucket is deleted, and another user can claim its name after it is released. To completely stop using OSS, you must delete all buckets in your account.

Warning

After a bucket is deleted, its name is released and can be claimed by another user. To reserve the bucket name, empty the bucket instead of deleting it.
Bucket deletion is permanent and data cannot be recovered. Before proceeding, confirm the data is no longer needed or back it up first. For instructions, see Back up a bucket.

Notes

In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS from other Alibaba Cloud services in the same region as OSS, use an internal endpoint. For more information about OSS regions and endpoints, see Regions and endpoints.
In this topic, access credentials are obtained from environment variables. For more information about how to configure access credentials, see Configure access credentials.
This topic demonstrates creating an OSSClient instance with an OSS endpoint. For alternative configurations, such as using a custom domain or authenticating with credentials from Security Token Service (STS), see Configure a client (Go SDK V1).
Before deleting the bucket, clean up resources that must be deleted.

Permissions

By default, an Alibaba Cloud account has full permissions. RAM users or RAM roles under an Alibaba Cloud account do not have any permissions by default. The Alibaba Cloud account or account administrator must grant operation permissions through RAM policies or Bucket Policy.

Sample code

The following code provides an example of how to delete the bucket named examplebucket:

package main

import (
	"fmt"
	"os"

	"github.com/aliyun/aliyun-oss-go-sdk/oss"
)

func main() {
	/// Obtain access credentials from environment variables. Before you run the sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are configured. 
	provider, err := oss.NewEnvironmentVariableCredentialsProvider()
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}

	// Create an OSSClient instance. 
	// Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. Specify your actual endpoint.
	// Specify the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the region to cn-hangzhou. Specify the actual region.
	clientOptions := []oss.ClientOption{oss.SetCredentialsProvider(&provider)}
	clientOptions = append(clientOptions, oss.Region("yourRegion"))
	// Specify the version of the signature algorithm.
	clientOptions = append(clientOptions, oss.AuthVersion(oss.AuthV4))
	client, err := oss.New("yourEndpoint", "", "", clientOptions...)
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}

	// Specify the name of the bucket. Example: examplebucket. 
	// Delete the bucket. 
	err = client.DeleteBucket("examplebucket")
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}
}
