TagResources - Auto Scaling - Alibaba Cloud Documentation Center

Creates and attaches tags. You can call the TagResources operation to uniformly create and attach tags to your Auto Scaling resources, streamlining resource management. This capability empowers you to categorize resources based on tags, thereby enhancing the overall efficiency of resource allocation and utilization.

Operation description

You can attach up to 20 tags to a scaling group.

**

Note Before you attach tags to a specific Auto Scaling resource, Alibaba Cloud automatically verifies the current number of tags attached to that resource. In the event the proposed addition would exceed the maximum allowed number of tags, an error message will be promptly returned after you call this operation.
If you set Tags.Propagate to true, any tags attached to your scaling group will be automatically propagated to new instances that are subsequently created in the scaling group, without affecting existing instances.
If both the scaling configuration and the scaling group have tags attached, and tag propagation from the scaling group is enabled, the tags of newly created instances comply with the following rules:
- Instances set to join the scaling group will inherit the following tags: tags attached to the scaling configuration that initiates the instance creation and tags attached to the scaling group that are allowed to propagate to these instances upon instance creation.
- If the tag keys of the scaling configuration and those attached to the scaling group and propagated to the instances are identical, the tags attached to the scaling group and propagated to the instances will be overwritten by the tags of the scaling configuration.

Debugging
