Attach labels to your services and let Traefik do the rest!
One of the best feature of Traefik is to delegate the routing configuration to the application level.
With Rancher, Traefik can leverage labels attached to a service to generate routing rules.
!!! warning "Labels & sensitive data"
We recommend to *not* use labels to store sensitive data (certificates, credentials, etc).
Instead, we recommend to store sensitive data in a safer storage (secrets, file, etc).
!!! important "This provider is specific to Rancher 1.x."
Rancher 2.x requires Kubernetes and does not have a metadata endpoint of its own for Traefik to query.
