### Kubernetes CRD
|
|
|
|
|
|
|
|
|
|
In v2.1, a new Kubernetes CRD called `TraefikService` was added.
|
|
|
|
|
While updating an installation to v2.1,
|
|
|
|
|
one should apply that CRD, and update the existing `ClusterRole` definition to allow Traefik to use that CRD.

|
|
|
|
|
|
|
|
To add that CRD and enhance the permissions, following definitions need to be applied to the cluster.

After having both resources applied, Traefik will work properly.
