[SOLVED] Discovery server behind traefik (2.8)

@kevdog , I might have small question on which I can’t find answer easily (probably wrong search queries made from my end).

In your example, you’ve

    syncthing-discosvr:
      <<: *modern_tls

Which uses reference anchor used earlier:

    modern: &modern_tls

Question is how to use such reference across different yaml files? I like to keep app related settings within single files for easy portability and as above section defines default which I want to apply to other apps/traefik services, question is how to use that reference to modern_tls defined in different file?

Error occurred during watcher callback: ... yaml: unknown anchor 'modern_tls' referenced"

I have a feeling that it won’t work: https://yaml.org/spec/1.2-old/spec.html#id2765878

Is there any other way to keep definitions in one place and re-use in other files?
