Object Storage Service:Create buckets

Last Updated:Sep 13, 2023

A bucket is a container used to store objects in Object Storage Service (OSS). All objects in OSS are stored in buckets. This topic describes how to create 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 create a bucket, you must have the oss:PutBucket permission. For more information, see Common examples of RAM policies.

Examples

The following code provides an example on how to create 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)
    }

    // Create a bucket named examplebucket. Set the storage class to IA (oss.StorageIA), the ACL to public-read (oss.ACLPublicRead), and the redundancy type to ZRS (oss.RedundancyZRS). 
    err = client.CreateBucket("examplebucket", oss.StorageClass(oss.StorageIA), oss.ACL(oss.ACLPublicRead), oss.RedundancyType(oss.RedundancyZRS))
    if err != nil {
        fmt.Println("Error:", err)
        os.Exit(-1)
    }
}
