Configuring Tags for a Bucket (SDK for Java)
Function
If you add tags to a bucket, SDRs generated for the requests sent to this bucket will include these tags, so you can use the tags to classify SDRs for detailed cost analysis. For example, if you have an application that uploads its running data to a bucket, you can tag the bucket with the application name. In this manner, the costs of the application can be analyzed using tags in SDRs.
This API adds tags to a bucket.
If you have any questions during development, post them on the Issues page of GitHub.
Restrictions
- A bucket can have a maximum of 10 tags.
- To configure tags for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketTagging in IAM or PutBucketTagging in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.
- The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.
