Configuring Tags for a Bucket

Functions

This operation adds tags to a bucket.

After tags are added to a bucket, all service detail records (SDRs) generated by the requests for this bucket will have the same tags. You can categorize the SDRs for detailed cost analysis. For example, if a running application uploads data to a bucket, you can tag the bucket with the application name. In this manner, the costs on the application can be analyzed using tags in SDRs.

To perform this operation, you must have the PutBucketTagging permission. By default, only the bucket owner can delete the tags of a bucket. The bucket owner can allow other users to perform this operation by setting a bucket policy or granting them the permission.

Constraints

A bucket can have up to 20 tags.
