My stack-level tags aren't propagating to resources in my AWS CloudFormation stack.
Short description
Propagation of stack-level tags to resources can vary by resource. CloudFormation supports propagation of stack-level tags only for resources with the Tags property. For a list of AWS resources and their property types, see AWS resource and property types reference.
The following examples demonstrate the difference in stack-level tag propagation between a resource that supports the Tags property, and one that doesn't.
Resolution
Resource that supports the Tags property
The resourceAWS::S3::Bucket supports the Tags property.
Create a stack with the AWS::S3::Bucket resource and specify stack-level tags.
After the stack is created, the S3 bucket resource has the propagated stack-level tags with the aws: prefix.
Resource that doesn't support the Tags property
Although the PutRule API allows you to specify tags, the AWS::Events::Rule resource doesn't support the Tags property.
Create a stack with the AWS::Events::Rule resource and specify stack-level tags.
After the stack is created, the Events Rule resource doesn't have the propagated stack-level tags.
Search for or create an issue through GitHub
If a stack-level tag isn't propagating for a resource that supports the Tags property, then check the cloudformation-coverage-roadmap on the GitHub website to see if it's a known issue. If it isn't submitted as an issue, then choose New issue to create one.
