## Routing Configuration

Trafik uses [container labels](https://docs.docker.com/engine/reference/commandline/run/#set-metadata-on-container--l---label---label-file) to retrieve its routing configuration.

|
||||
However, as the community expressed the need to benefit from Traefik features without resorting to (lots of) annotations,
|
||||
we ended up writing a [Custom Resource Definition](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/) (alias CRD in the following) for an IngressRoute type, defined below, in order to provide a better way to configure access to a Kubernetes cluster.
|
||||
|
||||
## Configuration Requirements
|
||||
|
||||
!!! tip "All Steps for a Successful Deployment"
|
||||
|
||||
* Add/update **all** the Traefik resources [definitions](../reference/dynamic-configuration/kubernetes-crd.md#definitions)
|
||||
* Add/update the [RBAC](https://kubernetes.io/docs/reference/access-authn-authz/rbac/) for the Traefik custom resources
|
||||
* Use [Helm Chart](../getting-started/install-traefik.md#use-the-helm-chart) or use a custom Traefik Deployment
|
||||
* Enable the kubernetesCRD provider
|
||||
* Apply the needed kubernetesCRD provider [configuration](#provider-configuration)
|
||||
* Add all needed traefik custom [resources](../reference/dynamic-configuration/kubernetes-crd.md#resources)
|
||||
|
||||
??? example "Initializing Resource Definition and RBAC"
|
||||
|
||||
```yaml tab="Traefik Resource Definition"
|
||||
# All resources definition must be declared
|
||||
--8<-- "content/reference/dynamic-configuration/kubernetes-crd-definition.yml"
|
||||
```
|
||||
|
||||
```yaml tab="RBAC for Traefik CRD"
|
||||
--8<-- "content/reference/dynamic-configuration/kubernetes-crd-rbac.yml"
|
||||
```
|
||||
|
||||
## Resource Configuration
|
||||
|
||||
See the dedicated section in [routing](../routing/providers/kubernetes-crd.md).
|
||||
When using KubernetesCRD as a provider,
|
||||
Traefik uses [Custom Resource Definition](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/) to retrieve its routing configuration.
|
||||
Traefik Custom Resource Definitions are a Kubernetes implementation of the Traefik concepts. The main particularities are:
|
||||
|
||||
* The usage of `name` **and** `namespace` to refer to another Kubernetes resource.
|
||||
* The usage of [secret](https://kubernetes.io/docs/concepts/configuration/secret/) for sensible data like:
|
||||
* TLS certificate.
|
||||
* Authentication data.
|
||||
* The structure of the configuration.
|
||||
* The obligation to declare all the [definitions](../reference/dynamic-configuration/kubernetes-crd.md#definitions).
|
||||
|
||||
The Traefik CRD are building blocks which you can assemble according to your needs.
|
||||
See the list of CRDs in the dedicated [routing section](../routing/providers/kubernetes-crd.md).
