Creating a Bucket

A bucket is a global namespace of OBS and is a data container. It functions as a root directory of a file system and can store objects. The following code shows how to create a bucket:

CreateBucketRequest request = new CreateBucketRequest();
request.BucketName = "bucketname";
client.CreateBucket(request);
  • Bucket names are globally unique. Ensure that the bucket you create is named differently from any other bucket.
  • A bucket name must comply with the following rules:
    • Contains 3 to 63 characters, chosen from lowercase letters, digits, hyphens (-), and periods (.), and starts with a digit or letter.
    • Cannot be an IP address or similar.
    • Cannot start or end with a hyphen (-) or period (.)
    • Cannot contain two consecutive periods (.), for example, my..bucket.
    • Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket.
  • If you create buckets of the same name, no error will be reported and the bucket properties comply with those set in the first creation request.
  • For more information, see Creating a Bucket.
