delete https://api.linode.com//object-storage/buckets//
Removes a single bucket.
You need to remove all objects from a bucket before you can delete it. While you can delete a bucket using the s3cmd command-line tool, this operation fails if the bucket contains too many objects. The best way to empty large buckets is to use the S3 API to configure lifecycle policies. Set a policy to remove all objects, wait a day or more for the system to remove all objects, then delete the bucket.
The S3 API equivalent operation offers more detail.
