Object Storage Service:Delete a bucket

Last Updated:Sep 26, 2023

If you no longer use a bucket, you can delete the bucket to stop unnecessary charges.

Warning

Deleted buckets cannot be recovered. Make sure that the data in the buckets is no longer required before you delete the buckets. If you want to continue using the data in the buckets, back up the data in advance. For more information, see Back up buckets.

Prerequisites

  • All objects in the bucket are deleted.

    • For more information about how to manually delete a small number of objects, see Delete objects.

    • If you want to delete a large number of objects, we recommend that you configure lifecycle rules to delete the objects in batches. For more information, see Configure lifecycle rules.

    Important

    If versioning is enabled for the bucket that you want to delete, make sure that all versions of objects in the bucket are deleted. For more information, see Configure versioning.

  • Parts generated by multipart upload or resumable upload tasks in the bucket are deleted. For more information, see Delete parts.

  • All LiveChannels in the bucket are deleted. For more information, see DeleteLiveChannel.

Usage notes

  • In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS by using other Alibaba Cloud services in the same region as OSS, use an internal endpoint. For more information about the regions and endpoints supported by OSS, 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.

  • In this topic, an OSSClient instance is created by using an OSS endpoint. If you want to create an OSSClient instance by using custom domain names or Security Token Service (STS), see Create an OSSClient instance.

  • To delete a bucket, you must have the oss:DeleteBucket permission. For more information, see Common examples of RAM policies.

Sample code

The following sample code shows how to delete a bucket named examplebucket:

import com.aliyun.oss.ClientException;
import com.aliyun.oss.OSS;
import com.aliyun.oss.common.auth.*;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.OSSException;

public class Demo {

    public static void main(String[] args) throws Exception {
        // In this example, the endpoint of the China (Hangzhou) region is used. Specify your actual endpoint. 
        String endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
        // 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. 
        EnvironmentVariableCredentialsProvider credentialsProvider = CredentialsProviderFactory.newEnvironmentVariableCredentialsProvider();
        // Specify the name of the bucket. Example: examplebucket. 
        String bucketName = "examplebucket";

        // Create an OSSClient instance. 
        OSS ossClient = new OSSClientBuilder().build(endpoint, credentialsProvider);

        try {
            // Delete the bucket. 
            ossClient.deleteBucket(bucketName);
        } catch (OSSException oe) {
            System.out.println("Caught an OSSException, which means your request made it to OSS, "
                    + "but was rejected with an error response for some reason.");
            System.out.println("Error Message:" + oe.getErrorMessage());
            System.out.println("Error Code:" + oe.getErrorCode());
            System.out.println("Request ID:" + oe.getRequestId());
            System.out.println("Host ID:" + oe.getHostId());
        } catch (ClientException ce) {
            System.out.println("Caught an ClientException, which means the client encountered "
                    + "a serious internal problem while trying to communicate with OSS, "
                    + "such as not being able to access the network.");
            System.out.println("Error Message:" + ce.getMessage());
        } finally {
            if (ossClient != null) {
                ossClient.shutdown();
            }
        }
    }
}
