Object Storage Service:Delete a bucket

Last Updated:Sep 19, 2023

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


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.

Usage notes

  • In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access Object Storage Service (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, 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 oss:DeleteBucket permission. For more information, see Common examples of RAM policies.


  • 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.


    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.


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

#include <alibabacloud/oss/OssClient.h>
using namespace AlibabaCloud::OSS;

int main(void)
    /* Initialize information about the account that is used to access OSS. */
    /* 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 */
    std::string Endpoint = "yourEndpoint";
    /* Specify the name of the bucket. Example: examplebucket. */
    std::string BucketName = "examplebucket";

    /* Initialize resources, such as network resources. */

    ClientConfiguration conf;
    /* 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. */
    auto credentialsProvider = std::make_shared<EnvironmentVariableCredentialsProvider>();
    OssClient client(Endpoint, credentialsProvider, conf);

    /* Delete the bucket. */
    DeleteBucketRequest request(BucketName);
    auto outcome = client.DeleteBucket(request);

    if (outcome.isSuccess()) {
    std::cout << "Delete bucket successfully." << std::endl;
    } else {
    std::cout << "Failed to delete bucket. Error code: " << outcome.error().Code()
              << ", Message: " << outcome.error().Message()
              << ", RequestId: " << outcome.error().RequestId() << std::endl;

    /* Release resources, such as network resources. */
    return 0;
