ApsaraDB RDS:TagResources

Last Updated:Sep 26, 2023

Creates and adds tags to one or more ApsaraDB RDS instances.

Operation Description

If you have a large number of instances, you can create multiple tags and add these tags to the instances. Then, you can query instances by tag.

  • A tag consists of a key and a value. Each key must be unique in a region for an Alibaba Cloud account. Different keys can be mapped to the same value.
  • If the tag that you specify does not exist, this tag is automatically created and added to the specified instance.
  • If the key of the specified tag is the same as that of an existing tag, the specified tag overwrites the existing tag.
  • You can add up to 20 tags to an instance.
  • You can add tags to up to 50 instances in each call.


You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
