Object Storage Service:Delete a bucket

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 Initialization.

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

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.

Sample code

The following sample code shows how to delete a 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. 
    client, err := oss.New("yourEndpoint", "", "", oss.SetCredentialsProvider(&provider))
    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)
    }
}
