Rancher v2 migration rancher.api / rancher.metadata are gone?

Migrating from 1.7 to 2.0 i stumbled uppon [providers.rancher.api] and [providers.rancher.metadata] which ado no longer exist or at least are not documented right now on https://docs.traefik.io/v2.0/providers/rancher/

Are there any hints on what changed / why it changed or how to adopt?

Thanks

In Traefik v2 we made the choice to keep only metadata.

https://docs.traefik.io/providers/rancher/

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.

Thank you, i missed that header. So the API mode has been removed.
That is why prefix has no nesting under metada anymore and is toplevel - make sense. Thanks

For those who look for a Traefik 2.0.0 compatible rancher-catalog, i have one here now https://github.com/EugenMayer/docker-rancher-extra-catalogs/tree/master/templates/traefik - there are also 1.7.x versions.
