Creating a Bucket

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

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:

obsClient.createBucket({
       Bucket : 'bucketname',
}, (err, result) => {
       if(err){
              console.error('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
       }
});
  • 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.
    • 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.
  • During bucket creation, if the endpoint you use corresponds to the default region CN North-Beijing1 (cn-north-1), specifying a region is not a must. If the endpoint you use corresponds to any other region, except the default one, you must set the region to the one that the used endpoint corresponds to. To view the valid regions, see Regions and Endpoints. For example, if the endpoint used for initialization is obs.ap-southeast-1.myhuaweicloud.com, you must set Location to ap-southeast-1 when you create a bucket. Otherwise, status code 400 will be returned.
