Filter resources based on dynamic tag name following some pattern.

[AbhishekSinha47]

How to filter resources based on dynamic tag name following some pattern? The tag name is say 'custodian-xyz', where xyz changes but 'custodian' is constant. Can we filter based on the tag name using regex like we can apply 'regex' option to 'Values'. Eg:

filters:
    - type: value
      key: tag:custodian*
      value: true
      op: regex

I have put tag name as 'custodian*' but that does not seem to work. @kapilt can you please guide?

can you describe the use case, are you just asserting the presence of the named dynamic tag on a resource, or its value?

Yeah, I am just asserting the presence of the named dynamic tag on a resource. Eg: tag name 'custodian-xyz', here 'custodian-' remains constant whereas 'xyz' varies in different resources. Hope this makes it clear.
