## Routing Configuration
|
|
|
|
### Custom Resource Definition (CRD)
|
|
|
|
* You can find an exhaustive list, generated from Traefik's source code, of the custom resources and their attributes in [the reference page](../../reference/dynamic-configuration/kubernetes-crd.md).
|
|
* Validate that [the prerequisites](../../providers/kubernetes-crd.md#configuration-requirements) are fulfilled before using the Traefik custom resources.
|
|
* Traefik CRDs are building blocks that you can assemble according to your needs.
|
|
|
|
You can find an excerpt of the available custom resources in the table below:
|
|
|
|
| Kind | Purpose | Concept Behind |
|
|
|------------------------------------------|---------------------------------------------------------------|----------------------------------------------------------------|
|
|
| [IngressRoute](#kind-ingressroute) | HTTP Routing | [HTTP router](../routers/index.md#configuring-http-routers) |
|
|
| [Middleware](#kind-middleware) | Tweaks the HTTP requests before they are sent to your service | [HTTP Middlewares](../../middlewares/overview.md) |
|
|
| [TraefikService](#kind-traefikservice) | Abstraction for HTTP loadbalancing/mirroring | [HTTP service](../services/index.md#configuring-http-services) |
|
|
| [IngressRouteTCP](#kind-ingressroutetcp) | TCP Routing | [TCP router](../routers/index.md#configuring-tcp-routers) |
|
|
| [TLSOptions](#kind-tlsoption) | Allows to configure some parameters of the TLS connection | [TLSOptions](../../https/tls.md#tls-options) |
|
|
|
|
### Kind: `IngressRoute`
|
|
|
|
`IngressRoute` is the CRD implementation of a [Traefik HTTP router](../routers/index.md#configuring-http-routers).
|
|
|
|
Register the `IngressRoute` kind in the Kubernetes cluster before creating `IngressRoute` objects.

|
```
|
|
|
|
!!! important "Configuring Backend Protocol"
|
|
|
|
There are 3 ways to configure the backend protocol for communication between Traefik and your pods:
|
|
|
|
- Setting the scheme explicitly (http/https/h2c)
|
|
- Configuring the name of the kubernetes service port to start with https (https)
|
|
- Setting the kubernetes service port to use port 443 (https)
|
|
|
|
If you do not configure the above, Traefik will assume an http connection.
|
|
|
|
### Kind: `Middleware`
|
|
|
|
`Middleware` is the CRD implementation of a [Traefik middleware](../../middlewares/overview.md).
|
|
|
|
Register the `Middleware` kind in the Kubernetes cluster before creating `Middleware` objects or referencing middlewares in the [`IngressRoute`](#kind-ingressroute) objects.
|
|
|
|
??? "Declaring and Referencing a Middleware"
|
|
|
|
```yaml tab="Middleware"
|
|
apiVersion: traefik.containo.us/v1alpha1
|
|
kind: Middleware
|
|
metadata:
|
|
name: stripprefix
|
|
namespace: foo
|
|
|
|
spec:
|
|
stripPrefix:
|
|
prefixes:
|
|
- /stripit
|
|
```
|
|
|
|
```yaml tab="IngressRoute"
|
|
apiVersion: traefik.containo.us/v1alpha1
|
|
kind: IngressRoute
|
|
metadata:
|
|
name: ingressroutebar
|
|
|
|
spec:
|
|
entryPoints:
|
|
- web
|
|
routes:
|
|
- match: Host(`bar.com`) && PathPrefix(`/stripit`)
|
|
kind: Rule
|
|
services:
|
|
- name: whoami
|
|
port: 80
|
|
middlewares:
|
|
- name: stripprefix
|
|
namespace: foo
|
|
```
|
|
|
|
!!! important "Cross-provider namespace"
|
|
|
|
As Kubernetes also has its own notion of namespace, one should not confuse the kubernetes namespace of a resource
|
|
(in the reference to the middleware) with the [provider namespace](../../middlewares/overview.md#provider-namespace),
|
|
when the definition of the middleware comes from another provider.
|
|
In this context, specifying a namespace when referring to the resource does not make any sense, and will be ignored.
|
|
|
|
More information about available middlewares in the dedicated [middlewares section](../../middlewares/overview.md).
|
|
|
|
### Kind: `TraefikService`
|
|
|
|
`TraefikService` is the CRD implementation of a ["Traefik Service"](../services/index.md).
|
|
|
|
Register the `TraefikService` kind in the Kubernetes cluster before creating `TraefikService` objects,
|
|
referencing services in the [`IngressRoute`](#kind-ingressroute)/[`IngressRouteTCP`](#kind-ingressroutetcp) objects or recursively in others `TraefikService` objects.
|
|
|
|
!!! info "Disambiguate Traefik and Kubernetes Services "
|
|
|
|
As the field `name` can reference different types of objects, use the field `kind` to avoid any ambiguity.
|
|
|
|
The field `kind` allows the following values:
|
|
|
|
* `Service` (default value): to reference a [Kubernetes Service](https://kubernetes.io/docs/concepts/services-networking/service/)
|
|
* `TraefikService`: to reference another [Traefik Service](../services/index.md)
|
|
|
|
`TraefikService` object allows to use any (valid) combinations of:
|
|
|
|
* servers [load balancing](#server-load-balancing).
|
|
* services [Weighted Round Robin](#weighted-round-robin) load balancing.
|
|
* services [mirroring](#mirroring).
|
|
|

!!! 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`).
|
|
|
|
### Kind `IngressRouteTCP`
|
|
|
|
`IngressRouteTCP` is the CRD implementation of a [Traefik TCP router](../routers/index.md#configuring-tcp-routers).
|
|
|
|
Register the `IngressRouteTCP` kind in the Kubernetes cluster before creating `IngressRouteTCP` objects.

### Kind: `TLSOption`

`TLSOption` is the CRD implementation of a [Traefik "TLS Option"](../../https/tls.md#tls-options).

|
Register the `TLSOption` kind in the Kubernetes cluster before creating `TLSOption` objects
|
|
or referencing TLS options in the [`IngressRoute`](#kind-ingressroute) / [`IngressRouteTCP`](#kind-ingressroutetcp) objects.
