+# Traefik & Kubernetes
+
+The Kubernetes Ingress Controller, The Custom Resource Way.
+{: .subtitle }
+
+[comment]: # (Link "Kubernetes Ingress controller" to ./kubernetes-ingress.md)
+
+The Traefik Kubernetes provider used to be a Kubernetes Ingress controller in the strict sense of the term; that is to say,
+it would manage access to a cluster services by supporting the [Ingress](https://kubernetes.io/docs/concepts/services-networking/ingress/) specification.
+
+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.
+
+## Traefik IngressRoute definition
+
+```yaml
+--8<-- "content/providers/crd_ingress_route.yml"
+```
+
+That `IngressRoute` kind can then be used to define an `IngressRoute` object, such as:
+
+```yaml
+apiVersion: traefik.containo.us/v1alpha1
+kind: IngressRoute
+metadata:
+  name: ingressroutefoo.crd
+
+spec:
+  entrypoints:
+    - web
+  routes:
+  # Match is the rule corresponding to an underlying router.
+  # Later on, match could be the simple form of a path prefix, e.g. just "/bar",
+  # but for now we only support a traefik style matching rule.
+  - match: Host(`foo.com`) && PathPrefix(`/bar`)
+    # kind could eventually be one of "Rule", "Path", "Host", "Method", "Header",
+    # "Parameter", etc, to support simpler forms of rule matching, but for now we
+    # only support "Rule".
+    kind: Rule
+    # Priority disambiguates rules of the same length, for route matching.
+    priority: 12
+    services:
+    - name: whoami
+      port: 80
+```
+
+## Middleware
+
+Additionally, to allow for the use of middlewares in an `IngressRoute`, we defined the CRD below for the `Middleware` kind.
+
+```yaml
+--8<-- "content/providers/crd_middlewares.yml"
+```
+
+Once the `Middleware` kind has been registered with the Kubernetes cluster, it can then be used in `IngressRoute` definitions, such as:
+
+```yaml
+apiVersion: traefik.containo.us/v1alpha1
+kind: Middleware
+metadata:
+  name: stripprefix
+
+spec:
+  stripprefix:
+    prefixes:
+      - /stripit
+
+---
+apiVersion: traefik.containo.us/v1alpha1
+kind: IngressRoute
+metadata:
+  name: ingressroutebar.crd
+
+spec:
+  entrypoints:
+    - web
+  routes:
+  - match: Host(`bar.com`) && PathPrefix(`/stripit`)
+    kind: Rule
+    services:
+    - name: whoami
+      port: 80
+    middlewares:
+    - name: stripprefix
+```
+
+## TLS
+
+To allow for TLS, we made use of the `Secret` kind, as it was already defined, and it can be directly used in an `IngressRoute`:
+
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: supersecret
+
+data:
+  tls.crt: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0tLS0tCi0tLS0tRU5EIENFUlRJRklDQVRFLS0tLS0=
+  tls.key: LS0tLS1CRUdJTiBQUklWQVRFIEtFWS0tLS0tCi0tLS0tRU5EIFBSSVZBVEUgS0VZLS0tLS0=
+
+---
+apiVersion: traefik.containo.us/v1alpha1
+kind: IngressRoute
+metadata:
+  name: ingressroutetls.crd
+
+spec:
+  entryPoints:
+    - web
+  routes:
+  - match: Host(`foo.com`) && PathPrefix(`/bar`)
+    kind: Rule
+    services:
+    - name: whoami
+      port: 443
+  tls:
+    secretName: supersecret
+```
