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.
  • 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.

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.

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 IngressRoute service
  • on both sides, you'll be warned if the ports don't match, and the IngressRoute service port is used

Thus, in case of two sides port definition, Traefik expects a match between ports.

Register the Middleware kind in the Kubernetes cluster before creating Middleware objects or referencing middlewares in the IngressRoute objects.

      port: 80
    middlewares:
    - name: stripprefix
      namespace: foo

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, 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:

TraefikService object allows to use any (valid) combinations of:

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).

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.

To keep a session open with the same server, the client would then need to specify the two levels within the cookie for each request, e.g. with curl:

curl -H Host:example.com -b "lvl1=default-whoami1-80; lvl2=http://10.42.0.6:80" http://localhost:8000/foo

assuming 10.42.0.6 is the IP address of one of the replicas (a pod then) of the whoami1 service.

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, 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.

More information about available TCP middlewares in the dedicated middlewares section.

Kind: IngressRouteUDP

IngressRouteUDP is the CRD implementation of a Traefik UDP router.

Register the IngressRouteUDP kind in the Kubernetes cluster before creating IngressRouteUDP objects.

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 IngressRouteUDP service
  • on both sides, you'll be warned if the ports don't match, and the IngressRouteUDP service port is used

Thus, in case of two sides port definition, Traefik expects a match between ports.

References and namespaces

If the optional namespace attribute is not set, the configuration will be applied with the namespace of the IngressRoute.

Additionally, when the definition of the TLS option is from another provider, the cross-provider syntax (middlewarename@provider) should be used to refer to the TLS option. Specifying a namespace attribute in this case would not make any sense, and will be ignored.

Kind: TLSStore

TLSStore is the CRD implementation of a Traefik "TLS Store".

Register the TLSStore kind in the Kubernetes cluster before creating TLSStore objects or referencing TLS stores in the IngressRoute / IngressRouteTCP objects.

Default TLS Store

Traefik currently only uses the TLS Store named "default". This means that you cannot have two stores that are named default in different Kubernetes namespaces. For the time being, please only configure one TLSStore named default.

ServersTransport is the CRD implementation of a ServersTransport.

[6] forwardingTimeouts Timeouts for requests forwarded to the servers.
[7] dialTimeout The amount of time to wait until a connection to a server can be established. If zero, no timeout exists.
[8] responseHeaderTimeout The amount of time to wait for a server's response headers after fully writing the request (including its body, if any). If zero, no timeout exists.
[9] idleConnTimeout The maximum amount of time an idle (keep-alive) connection will remain idle before closing itself. If zero, no timeout exists.
[10] peerCertURI URI used to match against SAN URIs during the server's certificate verification.

CA Secret

The CA secret must contain a base64 encoded certificate under either a tls.ca or a ca.crt key.

ServersTransport reference

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.
