Hello,

The dynamic configuration can be:

  • labels
  • files
  • ...

The dynamic configuration from labels are not merged with dynamic configuration from another source.

https://docs.traefik.io/v2.1/getting-started/configuration-overview/#the-dynamic-configuration

So your dynamic configuration from label is incomplete.

Also, You mixed Traefik v1 and Traefik v2 configuration.

You don't need to use files.
