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, 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:PutBucketpermission. For more information, see Attach a custom policy to a RAM user.
Sample code
The following sample code provides an example on how to create a bucket named examplebucket:
using Aliyun.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 https://oss-cn-hangzhou.aliyuncs.com.
var endpoint = "yourEndpoint";
// 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.
var accessKeyId = Environment.GetEnvironmentVariable("OSS_ACCESS_KEY_ID");
var accessKeySecret = Environment.GetEnvironmentVariable("OSS_ACCESS_KEY_SECRET");
// Specify the name of the bucket.
var bucketName = "examplebucket";
// Initialize an OssClient instance.
var client = new OssClient(endpoint, accessKeyId, accessKeySecret);
// Create a bucket.
try
{
var request = new CreateBucketRequest(bucketName);
// Set the access control list (ACL) of the bucket to PublicRead. The default value is private.
request.ACL = CannedAccessControlList.PublicRead;
// Set the redundancy type of the bucket to zone-redundant storage (ZRS).
request.DataRedundancyType = DataRedundancyType.ZRS;
client.CreateBucket(request);
Console.WriteLine("Create bucket succeeded");
}
catch (Exception ex)
{
Console.WriteLine("Create bucket failed. {0}", ex.Message);
}
