More information about available middlewares in the dedicated [middlewares section](../../middlewares/overview.md).
### Services
If one needs a setup more sophisticated than a load-balancer of servers (which is a Kubernetes Service kind behind the scenes),
one can define and use additional service objects specific to Traefik, based on the `TraefikService` kind defined in the CRD below.
```yaml
--8<-- "content/routing/providers/crd_traefikservice.yml"
```
Once the `TraefikService` kind has been registered with the Kubernetes cluster, it can then be used in `IngressRoute` definitions
(as well as recursively in other Traefik Services), such as below.
Note how the `name` field in the IngressRoute definition now refers to a TraefikService instead of a (Kubernetes) Service.
The reason this is allowed, and why a `name` can refer either to a TraefikService or a Service,
is because the `kind` field is used to break the ambiguity. The allowed values for this field are `TraefikService`, or `Service`
(which is the default value).
```yaml
apiVersion: traefik.containo.us/v1alpha1

```
!!! important "References and namespaces"
If the optional `namespace` attribute is not set, the configuration will be applied with the namespace of the current resource.
Additionally, when the definition of the `TraefikService` is from another provider,
the cross-provider syntax (service@provider) should be used to refer to the `TraefikService`, just as in the middleware case.
Specifying a namespace attribute in this case would not make any sense, and will be ignored (except if the provider is `kubernetescrd`).
### TLS Option
Additionally, to allow for the use of TLS options in an IngressRoute, we defined the CRD below for the TLSOption kind.
