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.
- Validate that the prerequisites 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 | HTTP Routing | HTTP router |
| Middleware | Tweaks the HTTP requests before they are sent to your service | HTTP Middlewares |
| TraefikService | Abstraction for HTTP loadbalancing/mirroring | HTTP service |
| IngressRouteTCP | TCP Routing | TCP router |
| MiddlewareTCP | Tweaks the TCP requests before they are sent to your service | TCP Middlewares |
| IngressRouteUDP | UDP Routing | UDP router |
| TLSOptions | Allows to configure some parameters of the TLS connection | TLSOptions |
| TLSStores | Allows to configure the default TLS store | TLSStores |
| ServersTransport | Allows to configure the transport between Traefik and the backends | ServersTransport |
Kind: IngressRoute¶
IngressRoute is the CRD implementation of a Traefik HTTP router.
Register the IngressRoute kind in the Kubernetes cluster before creating IngressRoute objects.

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.
Using Kubernetes ExternalName Service
Traefik backends creation needs a port to be set, however Kubernetes ExternalName Service could be defined without any port. Accordingly, Traefik supports defining a port in two ways:
- only on
IngressRouteservice - on both sides, you'll be warned if the ports don't match, and the
IngressRouteservice port is used
Thus, in case of two sides port definition, Traefik expects a match between ports.

To avoid creating the server load-balancer with the pods IPs and use Kubernetes Service clusterIP directly,
one should set the service NativeLB option to true.
Please note that, by default, Traefik reuses the established connections to the backends for performance purposes. This can prevent the requests load balancing between the replicas from behaving as one would expect when the option is set.
By default, NativeLB is false.

...Kind: Middleware¶
Middleware is the CRD implementation of a Traefik middleware.
Register the Middleware kind in the Kubernetes cluster before creating Middleware objects or referencing middlewares in the IngressRoute objects.

- match: Host(`example.com`) && PathPrefix(`/stripit`)
kind: Rule
services:
- name: whoami
port: 80
middlewares:
- name: stripprefix
namespace: fooCross-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, 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. Additionally, when you want to reference a Middleware from the CRD Provider, you have to append the namespace of the resource in the resource-name as Traefik appends the namespace internally automatically.
More information about available middlewares in the dedicated middlewares section.
Kind: TraefikService¶
TraefikService is the CRD implementation of a "Traefik Service".
Register the TraefikService kind in the Kubernetes cluster before creating TraefikService objects,
referencing services in the IngressRoute objects, or recursively in others TraefikService objects.
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 ServiceTraefikService: to reference another Traefik Service
TraefikService object allows to use any (valid) combinations of:
- Weighted Round Robin load balancing.
- Mirroring.

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).
Stickiness and load-balancing¶
As explained in the section about Sticky sessions, for stickiness to work all the way, it must be specified at each load-balancing level.
For instance, in the example below, there is a first level of load-balancing because there is a (Weighted Round Robin) load-balancing of the two whoami services,
and there is a second level because each whoami service is a replicaset and is thus handled as a load-balancer of servers.

Traefik backends creation needs a port to be set, however Kubernetes ExternalName Service could be defined without any port. Accordingly, Traefik supports defining a port in two ways:
- only on
IngressRouteTCPservice - on both sides, you'll be warned if the ports don't match, and the
IngressRouteTCPservice port is used
Thus, in case of two sides port definition, Traefik expects a match between ports.

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, when the definition of the TCP 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. Additionally, when you want to reference a MiddlewareTCP from the CRD Provider, you have to append the namespace of the resource in the resource-name as Traefik appends the namespace internally automatically.

Kind: TLSStore¶
TLSStore is the CRD implementation of a Traefik "TLS Store".
Register the TLSStore kind in the Kubernetes cluster before creating TLSStore objects.
Default TLS Store
Traefik currently only uses the TLS Store named "default".
This default TLSStore should be in a namespace discoverable by Traefik. Since it is used by default on IngressRoute and IngressRouteTCP objects, there never is a need to actually reference it.
This means that you cannot have two stores that are named default in different Kubernetes namespaces.
As a consequence, with respect to TLS stores, the only change that makes sense (and only if needed) is to configure the default TLSStore.

By default, the referenced ServersTransport CRD must be defined in the same Kubernetes service namespace.
To reference a ServersTransport CRD from another namespace,
the value must be of form namespace-name@kubernetescrd,
and the cross-namespace option must be enabled.
If the ServersTransport CRD is defined in another provider the cross-provider format name@provider should be used.
