Why use tag propagation-Resource Orchestration Service(ROS)-阿里云帮助中心

When you create or update a stack by calling an API, Resource Orchestration Service (ROS) propagates any specified tags to each resource in the stack that supports tags.

Usage notes

If a tag defined in the template has the same key as a stack tag:
- For a ROS stack, the tag defined for the resource in the template is used. For example, if the tag for resource A in the template is k1:v1, and you specify k1:v2 when you call CreateStack, the final tag for resource A is k1:v1.
- For a Terraform stack, the tag specified for the stack is used. For example, if the tag for resource A in the template is k1:v1, and you specify k1:v2 when you call CreateStack, the final tag for resource A is k1:v2.
If a resource in a template has no tags, or if the tag keys of the resource and the stack are different, the stack tags are propagated to the resource. For example, if resource A in the template has the tag k1:v1 and you specify the tag k2:v2 when you call CreateStack, the final tags for resource A are k1:v1,k2:v2.
Tag propagation occurs only when you create or update a stack by calling CreateStack or UpdateStack. Tags attached to a stack by calling TagResources are not propagated.
