Traefik follows the [Kubernetes support policy](https://kubernetes.io/releases/version-skew-policy/#supported-versions),
and supports at least the latest three minor versions of Kubernetes.
General functionality cannot be guaranteed for versions older than that.

# Traefik & Kubernetes with Gateway API
The Kubernetes Gateway API Controller.
{: .subtitle }
Gateway API is the evolution of Kubernetes APIs that relate to `Services`, such as `Ingress`.
The Gateway API project is part of Kubernetes, working under SIG-NETWORK.
The Kubernetes Gateway provider is a Traefik implementation of the [Gateway API](https://gateway-api.sigs.k8s.io/)
specifications from the Kubernetes Special Interest Groups (SIGs).
specification from the Kubernetes Special Interest Groups (SIGs).
This provider supports Gateway API [v1.1.0](https://github.com/kubernetes-sigs/gateway-api/releases/tag/v1.1.0) specification.
This provider supports version [v1.1.0](https://github.com/kubernetes-sigs/gateway-api/releases/tag/v1.1.0) of the Gateway API specification.
It fully supports all HTTP core and some extended features, as well as the `TCPRoute` and `TLSRoute` resources from the [Experimental channel](https://gateway-api.sigs.k8s.io/concepts/versioning/?h=#release-channels).
For more details, check out the conformance [report](https://github.com/kubernetes-sigs/gateway-api/tree/main/conformance/reports/v1.1.0/traefik-traefik).
## Requirements
{!kubernetes-requirements.md!}
!!! tip "All Steps for a Successful Deployment"
!!! info "Helm Chart"
* Add/update the Kubernetes Gateway API [definitions](../reference/dynamic-configuration/kubernetes-gateway.md#definitions).
* Add/update the [RBAC](../reference/dynamic-configuration/kubernetes-gateway.md#rbac) for the Traefik custom resources.
* Add all needed Kubernetes Gateway API [resources](../reference/dynamic-configuration/kubernetes-gateway.md#resources).
When using the Traefik [Helm Chart](../getting-started/install-traefik.md#use-the-helm-chart), the CRDs (Custom Resource Definitions) and RBAC (Role-Based Access Control) are automatically managed for you.
The only remaining task is to enable the `kubernetesGateway` in the chart [values](https://github.com/traefik/traefik-helm-chart/blob/master/traefik/values.yaml#L130).
## Examples
1. Install/update the Kubernetes Gateway API CRDs.
??? example "Kubernetes Gateway Provider Basic Example"
```yaml tab="Gateway API"
--8<-- "content/reference/dynamic-configuration/kubernetes-gateway-simple-https.yml"
```bash
# Install Gateway API CRDs from the Experimental channel.
kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.1.0/experimental-install.yaml
```
```yaml tab="Whoami Service"
--8<-- "content/reference/dynamic-configuration/kubernetes-whoami-svc.yml"
2. Install/update the Traefik [RBAC](../reference/dynamic-configuration/kubernetes-gateway.md#rbac).
```bash
# Install Traefik RBACs.
kubectl apply -f kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v3.1/docs/content/reference/dynamic-configuration/kubernetes-gateway-rbac.yml
```
```yaml tab="Traefik Service"
--8<-- "content/reference/dynamic-configuration/kubernetes-gateway-traefik-lb-svc.yml"
3. Deploy Traefik and enable the `kubernetesGateway` provider in the static configuration as detailed below:
```yaml tab="File (YAML)"
providers:
kubernetesGateway: {}
```
```yaml tab="Gateway API CRDs"
# All resources definition must be declared
--8<-- "content/reference/dynamic-configuration/gateway.networking.k8s.io_gatewayclasses.yaml"
--8<-- "content/reference/dynamic-configuration/gateway.networking.k8s.io_gateways.yaml"
--8<-- "content/reference/dynamic-configuration/gateway.networking.k8s.io_httproutes.yaml"
```toml tab="File (TOML)"
[providers.kubernetesGateway]
```
```yaml tab="RBAC"
--8<-- "content/reference/dynamic-configuration/kubernetes-gateway-rbac.yml"
```bash tab="CLI"
--providers.kubernetesgateway=true
```
The Kubernetes Gateway API project provides several guides on how to use the APIs.
These guides can help you to go further than the example above.
The [getting started guide](https://gateway-api.sigs.k8s.io/guides/) details how to install the CRDs from their repository.
## Routing Configuration
For now, the Traefik Gateway Provider can be used while following the below guides:
* [Simple Gateway](https://gateway-api.sigs.k8s.io/guides/simple-gateway/)
* [HTTP routing](https://gateway-api.sigs.k8s.io/guides/http-routing/)
* [TLS](https://gateway-api.sigs.k8s.io/guides/tls/)
## Resource Configuration
When using Kubernetes Gateway API as a provider, Traefik uses Kubernetes
[Custom Resource Definitions](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/)
to retrieve its routing configuration.
All concepts can be found in the official API concepts [documentation](https://gateway-api.sigs.k8s.io/concepts/api-overview/).
Traefik implements the following resources:
* `GatewayClass` defines a set of Gateways that share a common configuration and behaviour.
* `Gateway` describes how traffic can be translated to Services within the cluster.
* `HTTPRoute` defines HTTP rules for mapping requests from a Gateway to Kubernetes Services.
* `TCPRoute` defines TCP rules for mapping requests from a Gateway to Kubernetes Services.
* `TLSRoute` defines TLS rules for mapping requests from a Gateway to Kubernetes Services.
When using the Kubernetes Gateway API provider, Traefik uses the Gateway API CRDs to retrieve its routing configuration.
Check out the Gateway API concepts [documentation](https://gateway-api.sigs.k8s.io/concepts/api-overview/),
and the dedicated [routing section](../routing/providers/kubernetes-gateway.md) in the Traefik documentation.

When this policy attaches to a parent, the controller that manages the parent and the ancestors MUST add an entry to this list when the controller first sees the policy and SHOULD update the entry as appropriate when the relevant ancestor is modified. \n Note that choosing the relevant ancestor is left to the Policy designers; an important part of Policy design is designing the right object level at which to namespace this status. \n Note also that implementations MUST ONLY populate ancestor status for the Ancestor resources they are responsible for. Implementations MUST use the ControllerName field to uniquely identify the entries in this list that they are responsible for. \n Note that to achieve this, the list of PolicyAncestorStatus structs MUST be treated as a map with a composite key, made up of the AncestorRef and ControllerName fields combined. \n A maximum of 16 ancestors will be represented in this list. An empty list means the Policy is not relevant for any ancestors. \n If this slice is full, implementations MUST NOT add further entries. Instead they MUST consider the policy unimplementable and signal that on any related resources such as the ancestor that would be referenced here. For example, if this list was full on BackendTLSPolicy, no additional Gateways would be able to reference the Service targeted by the BackendTLSPolicy."
items:
description: "PolicyAncestorStatus describes the status of a route with respect to an associated Ancestor. \n Ancestors refer to objects that are either the Target of a policy or above it in terms of object hierarchy. For example, if a policy targets a Service, the Policy's Ancestors are, in order, the Service, the HTTPRoute, the Gateway, and the GatewayClass. Almost always, in this hierarchy, the Gateway will be the most useful object to place Policy status on, so we recommend that implementations SHOULD use Gateway as the PolicyAncestorStatus object unless the designers have a _very_ good reason otherwise. \n In the context of policy attachment, the Ancestor is used to distinguish which resource results in a distinct application of this policy. For example, if a policy targets a Service, it may have a distinct result per attached Gateway. \n Policies targeting the same resource may have different effects depending on the ancestors of those resources. For example, different Gateways targeting the same Service may have different capabilities, especially if they have different underlying implementations. \n For example, in BackendTLSPolicy, the Policy attaches to a Service that is used as a backend in a HTTPRoute that is itself attached to a Gateway. In this case, the relevant object for status is the Gateway, and that is the ancestor object referred to in this status. \n Note that a parent is also an ancestor, so for objects where the parent is the relevant object for status, this struct SHOULD still be used. \n This struct is intended to be used in a slice that's effectively a map, with a composite key made up of the AncestorRef and the ControllerName."

For example: Gateway has the AllowedRoutes field, and ReferenceGrant provides a generic way to enable any other kind of cross-namespace reference. \n ParentRefs from a Route to a Service in the same namespace are \"producer\" routes, which apply default routing rules to inbound connections from any namespace to the Service. \n ParentRefs from a Route to a Service in a different namespace are \"consumer\" routes, and these routing rules are only applied to outbound connections originating from the same namespace as the Route, for which the intended destination of the connections are a Service targeted as a ParentRef of the Route. \n Support: Core"

When both Port and SectionName are specified, the name and port of the selected listener must match both specified values. \n When the parent resource is a Service, this targets a specific port in the Service spec. When both Port (experimental) and SectionName are specified, the name and port of the selected port must match both specified values. \n Implementations MAY choose to support other parent resources.

For example, Gateway listeners can restrict which Routes can attach to them by Route kind, namespace, or hostname.

This matches the RFC 1123 definition of a hostname with 2 notable exceptions: \n 1. IPs are not allowed. 2. A hostname may be prefixed with a wildcard label (`*.`). The wildcard label MUST appear by itself as the first label. \n If a hostname is specified by both the Listener and GRPCRoute, there MUST be at least one intersecting hostname for the GRPCRoute to be attached to the Listener. For example: \n * A Listener with `test.example.com` as the hostname matches GRPCRoutes that have either not specified any hostnames, or have specified at least one of `test.example.com` or `*.example.com`. * A Listener with `*.example.com` as the hostname matches GRPCRoutes that have either not specified any hostnames or have specified at least one hostname that matches the Listener hostname. For example, `test.example.com` and `*.example.com` would both match. On the other hand, `example.com` and `test.example.net` would not match. \n Hostnames that are prefixed with a wildcard label (`*.`) are interpreted as a suffix match. That means that a match for `*.example.com` would match both `test.example.com`, and `foo.test.example.com`, but not `example.com`. \n If both the Listener and GRPCRoute have specified hostnames, any GRPCRoute hostnames that do not match the Listener hostname MUST be ignored. For example, if a Listener specified `*.example.com`, and the GRPCRoute specified `test.example.com` and `test.example.net`, `test.example.net` MUST NOT be considered for a match. \n If both the Listener and GRPCRoute have specified hostnames, and none match with the criteria above, then the GRPCRoute MUST NOT be accepted by the implementation. The implementation MUST raise an 'Accepted' Condition with a status of `False` in the corresponding RouteParentStatus. \n If a Route (A) of type HTTPRoute or GRPCRoute is attached to a Listener and that listener already has another Route (B) of the other type attached and the intersection of the hostnames of A and B is non-empty, then the implementation MUST accept exactly one of these two routes, determined by the following criteria, in order: \n * The oldest Route based on creation timestamp. * The Route appearing first in alphabetical order by \"{namespace}/{name}\". \n The rejected Route MUST raise an 'Accepted' condition with a status of 'False' in the corresponding RouteParentStatus. \n Support: Core"

parentRefs:
description: "ParentRefs references the resources (usually Gateways) that a Route wants to be attached to. Note that the referenced parent resource needs to allow this for the attachment to be complete. For Gateways, that means the Gateway needs to allow attachment from Routes of this kind and namespace. For Services, that means the Service must either be in the same namespace for a \"producer\" route, or the mesh implementation must support and allow \"consumer\" routes for the referenced Service. ReferenceGrant is not applicable for governing ParentRefs to Services - it is not possible to create a \"producer\" route for a Service in a different namespace from the Route. \n There are two kinds of parent resources with \"Core\" support: \n * Gateway (Gateway conformance profile) * Service (Mesh conformance profile, experimental, ClusterIP Services only) This API may be extended in the future to support additional kinds of parent resources. \n ParentRefs must be _distinct_. This means either that: \n * They select different objects. If this is the case, then parentRef entries are distinct. In terms of fields, this means that the multi-part key defined by `group`, `kind`, `namespace`, and `name` must be unique across all parentRef entries in the Route. * They do not select different objects, but for each optional field used, each ParentRef that selects the same object must set the same set of optional fields to different values. If one ParentRef sets a combination of optional fields, all must set the same combination. \n Some examples: \n * If one ParentRef sets `sectionName`, all ParentRefs referencing the same object must also set `sectionName`. * If one ParentRef sets `port`, all ParentRefs referencing the same object must also set `port`. * If one ParentRef sets `sectionName` and `port`, all ParentRefs referencing the same object must also set `sectionName` and `port`. \n It is possible to separately reference multiple distinct objects that may be collapsed by an implementation. For example, some implementations may choose to merge compatible Gateway Listeners together. If that is the case, the list of routes attached to those resources should also be merged. \n Note that for ParentRefs that cross namespace boundaries, there are specific rules. Cross-namespace references are only valid if they are explicitly allowed by something in the namespace they are referring to. For example, Gateway has the AllowedRoutes field, and ReferenceGrant provides a generic way to enable other kinds of cross-namespace reference. \n ParentRefs from a Route to a Service in the same namespace are \"producer\" routes, which apply default routing rules to inbound connections from any namespace to the Service. \n ParentRefs from a Route to a Service in a different namespace are \"consumer\" routes, and these routing rules are only applied to outbound connections originating from the same namespace as the Route, for which the intended destination of the connections are a Service targeted as a ParentRef of the Route. \n "

For example, Gateway listeners can restrict which Routes can attach to them by Route kind, namespace, or hostname.

If that is the case, they MUST clearly document how SectionName is interpreted. \n When unspecified (empty string), this will reference the entire resource. For the purpose of status, an attachment is considered successful if at least one section in the parent resource accepts it. For example, Gateway listeners can restrict which Routes can attach to them by Route kind, namespace, or hostname.

If no Gateway listeners accept attachment from this Route, the Route MUST be considered detached from the Gateway. \n Support: Core"

properties:
backendRefs:
description: "BackendRefs defines the backend(s) where matching requests should be sent. \n Failure behavior here depends on how many BackendRefs are specified and how many are invalid. \n If *all* entries in BackendRefs are invalid, and there are also no filters specified in this route rule, *all* traffic which matches this rule MUST receive an `UNAVAILABLE` status. \n See the GRPCBackendRef definition for the rules about what makes a single GRPCBackendRef invalid. \n When a GRPCBackendRef is invalid, `UNAVAILABLE` statuses MUST be returned for requests that would have otherwise been routed to an invalid backend. If multiple backends are specified, and some are invalid, the proportion of requests that would otherwise have been routed to an invalid backend MUST receive an `UNAVAILABLE` status. \n For example, if two backends are specified with equal weights, and one is invalid, 50 percent of traffic MUST receive an `UNAVAILABLE` status. Implementations may choose how that 50 percent is determined. \n Support: Core for Kubernetes Service \n Support: Implementation-specific for any other resource \n Support for weight: Core"

Implementations MAY infer the protocol from the Route type referring to the backend Service. \n If a Route is not able to send traffic to the backend using the specified protocol then the backend is considered invalid.

parentRefs:
description: "ParentRefs references the resources (usually Gateways) that a Route wants to be attached to. Note that the referenced parent resource needs to allow this for the attachment to be complete. For Gateways, that means the Gateway needs to allow attachment from Routes of this kind and namespace. For Services, that means the Service must either be in the same namespace for a \"producer\" route, or the mesh implementation must support and allow \"consumer\" routes for the referenced Service. ReferenceGrant is not applicable for governing ParentRefs to Services - it is not possible to create a \"producer\" route for a Service in a different namespace from the Route. \n There are two kinds of parent resources with \"Core\" support: \n * Gateway (Gateway conformance profile) * Service (Mesh conformance profile, experimental, ClusterIP Services only) This API may be extended in the future to support additional kinds of parent resources. \n ParentRefs must be _distinct_. This means either that: \n * They select different objects. If this is the case, then parentRef entries are distinct. In terms of fields, this means that the multi-part key defined by `group`, `kind`, `namespace`, and `name` must be unique across all parentRef entries in the Route. * They do not select different objects, but for each optional field used, each ParentRef that selects the same object must set the same set of optional fields to different values. If one ParentRef sets a combination of optional fields, all must set the same combination. \n Some examples: \n * If one ParentRef sets `sectionName`, all ParentRefs referencing the same object must also set `sectionName`. * If one ParentRef sets `port`, all ParentRefs referencing the same object must also set `port`. * If one ParentRef sets `sectionName` and `port`, all ParentRefs referencing the same object must also set `sectionName` and `port`. \n It is possible to separately reference multiple distinct objects that may be collapsed by an implementation. For example, some implementations may choose to merge compatible Gateway Listeners together. If that is the case, the list of routes attached to those resources should also be merged. \n Note that for ParentRefs that cross namespace boundaries, there are specific rules. Cross-namespace references are only valid if they are explicitly allowed by something in the namespace they are referring to. For example, Gateway has the AllowedRoutes field, and ReferenceGrant provides a generic way to enable other kinds of cross-namespace reference. \n ParentRefs from a Route to a Service in the same namespace are \"producer\" routes, which apply default routing rules to inbound connections from any namespace to the Service. \n ParentRefs from a Route to a Service in a different namespace are \"consumer\" routes, and these routing rules are only applied to outbound connections originating from the same namespace as the Route, for which the intended destination of the connections are a Service targeted as a ParentRef of the Route. \n "

parentRefs:
description: "ParentRefs references the resources (usually Gateways) that a Route wants to be attached to. Note that the referenced parent resource needs to allow this for the attachment to be complete. For Gateways, that means the Gateway needs to allow attachment from Routes of this kind and namespace. For Services, that means the Service must either be in the same namespace for a \"producer\" route, or the mesh implementation must support and allow \"consumer\" routes for the referenced Service. ReferenceGrant is not applicable for governing ParentRefs to Services - it is not possible to create a \"producer\" route for a Service in a different namespace from the Route. \n There are two kinds of parent resources with \"Core\" support: \n * Gateway (Gateway conformance profile) * Service (Mesh conformance profile, experimental, ClusterIP Services only) This API may be extended in the future to support additional kinds of parent resources. \n ParentRefs must be _distinct_. This means either that: \n * They select different objects. If this is the case, then parentRef entries are distinct. In terms of fields, this means that the multi-part key defined by `group`, `kind`, `namespace`, and `name` must be unique across all parentRef entries in the Route. * They do not select different objects, but for each optional field used, each ParentRef that selects the same object must set the same set of optional fields to different values. If one ParentRef sets a combination of optional fields, all must set the same combination. \n Some examples: \n * If one ParentRef sets `sectionName`, all ParentRefs referencing the same object must also set `sectionName`. * If one ParentRef sets `port`, all ParentRefs referencing the same object must also set `port`. * If one ParentRef sets `sectionName` and `port`, all ParentRefs referencing the same object must also set `sectionName` and `port`. \n It is possible to separately reference multiple distinct objects that may be collapsed by an implementation. For example, some implementations may choose to merge compatible Gateway Listeners together. If that is the case, the list of routes attached to those resources should also be merged. \n Note that for ParentRefs that cross namespace boundaries, there are specific rules. Cross-namespace references are only valid if they are explicitly allowed by something in the namespace they are referring to. For example, Gateway has the AllowedRoutes field, and ReferenceGrant provides a generic way to enable other kinds of cross-namespace reference. \n ParentRefs from a Route to a Service in the same namespace are \"producer\" routes, which apply default routing rules to inbound connections from any namespace to the Service. \n ParentRefs from a Route to a Service in a different namespace are \"consumer\" routes, and these routing rules are only applied to outbound connections originating from the same namespace as the Route, for which the intended destination of the connections are a Service targeted as a ParentRef of the Route. \n "

parentRefs:
description: "ParentRefs references the resources (usually Gateways) that a Route wants to be attached to. Note that the referenced parent resource needs to allow this for the attachment to be complete. For Gateways, that means the Gateway needs to allow attachment from Routes of this kind and namespace. For Services, that means the Service must either be in the same namespace for a \"producer\" route, or the mesh implementation must support and allow \"consumer\" routes for the referenced Service. ReferenceGrant is not applicable for governing ParentRefs to Services - it is not possible to create a \"producer\" route for a Service in a different namespace from the Route. \n There are two kinds of parent resources with \"Core\" support: \n * Gateway (Gateway conformance profile) * Service (Mesh conformance profile, experimental, ClusterIP Services only) This API may be extended in the future to support additional kinds of parent resources. \n ParentRefs must be _distinct_. This means either that: \n * They select different objects. If this is the case, then parentRef entries are distinct. In terms of fields, this means that the multi-part key defined by `group`, `kind`, `namespace`, and `name` must be unique across all parentRef entries in the Route. * They do not select different objects, but for each optional field used, each ParentRef that selects the same object must set the same set of optional fields to different values. If one ParentRef sets a combination of optional fields, all must set the same combination. \n Some examples: \n * If one ParentRef sets `sectionName`, all ParentRefs referencing the same object must also set `sectionName`. * If one ParentRef sets `port`, all ParentRefs referencing the same object must also set `port`. * If one ParentRef sets `sectionName` and `port`, all ParentRefs referencing the same object must also set `sectionName` and `port`. \n It is possible to separately reference multiple distinct objects that may be collapsed by an implementation. For example, some implementations may choose to merge compatible Gateway Listeners together. If that is the case, the list of routes attached to those resources should also be merged. \n Note that for ParentRefs that cross namespace boundaries, there are specific rules. Cross-namespace references are only valid if they are explicitly allowed by something in the namespace they are referring to. For example, Gateway has the AllowedRoutes field, and ReferenceGrant provides a generic way to enable other kinds of cross-namespace reference. \n ParentRefs from a Route to a Service in the same namespace are \"producer\" routes, which apply default routing rules to inbound connections from any namespace to the Service. \n ParentRefs from a Route to a Service in a different namespace are \"consumer\" routes, and these routing rules are only applied to outbound connections originating from the same namespace as the Route, for which the intended destination of the connections are a Service targeted as a ParentRef of the Route. \n "

For example, Gateway listeners can restrict which Routes can attach to them by Route kind, namespace, or hostname. If 1 of 2 Gateway listeners accept attachment from the referencing Route, the Route MUST be considered successfully attached. If no Gateway listeners accept attachment from this Route, the Route MUST be considered detached from the Gateway. \n Support: Core"

# Traefik & Kubernetes
# Traefik & Kubernetes with Gateway API
The Kubernetes Gateway API Controller.
{: .subtitle }
When using the Kubernetes Gateway API provider, Traefik leverages the Gateway API Custom Resource Definitions (CRDs) to obtain its routing configuration.
For detailed information on the Gateway API concepts and resources, refer to the official [documentation](https://gateway-api.sigs.k8s.io/).
## Configuration Examples
The Kubernetes Gateway API provider supports version [v1.1.0](https://github.com/kubernetes-sigs/gateway-api/releases/tag/v1.1.0) of the specification.
??? example "Configuring Kubernetes Gateway provider and Deploying/Exposing Services"
It fully supports all `HTTPRoute` core and some extended features, as well as the `TCPRoute` and `TLSRoute` resources from the [Experimental channel](https://gateway-api.sigs.k8s.io/concepts/versioning/?h=#release-channels).
```yaml tab="Gateway API"
--8<-- "content/reference/dynamic-configuration/kubernetes-gateway-simple-https.yml"
```
For more details, check out the conformance [report](https://github.com/kubernetes-sigs/gateway-api/tree/main/conformance/reports/v1.1.0/traefik-traefik).
```yaml tab="Whoami Service"
--8<-- "content/reference/dynamic-configuration/kubernetes-whoami-svc.yml"
```
## Deploying a Gateway
```yaml tab="Traefik Service"
--8<-- "content/reference/dynamic-configuration/kubernetes-gateway-traefik-lb-svc.yml"
```
A `Gateway` is a core resource in the Gateway API specification that defines the entry point for traffic into a Kubernetes cluster.
It is linked to a `GatewayClass`, which specifies the controller responsible for managing and handling the traffic, ensuring that it is directed to the appropriate Kubernetes backend services.
```yaml tab="RBAC"
--8<-- "content/reference/dynamic-configuration/kubernetes-gateway-rbac.yml"
```
The `GatewayClass` is a cluster-scoped resource typically defined by the infrastructure provider.
The following `GatewayClass` defines that gateways attached to it must be managed by the Traefik controller.
## Routing Configuration
### Custom Resource Definition (CRD)
* You can find an exhaustive list, of the custom resources and their attributes in
[the reference page](../../reference/dynamic-configuration/kubernetes-gateway.md) or in the Kubernetes
Sigs `Gateway API` [repository](https://github.com/kubernetes-sigs/gateway-api).
* Validate that [the prerequisites](../../providers/kubernetes-gateway.md#requirements) are fulfilled
before using the Traefik Kubernetes Gateway Provider.
You can find an excerpt of the supported Kubernetes Gateway API resources in the table below:
| Kind | Purpose | Concept Behind |
|------------------------------------|---------------------------------------------------------------------------|------------------------------------------------------------------------|
| [GatewayClass](#kind-gatewayclass) | Defines a set of Gateways that share a common configuration and behaviour | [GatewayClass](https://gateway-api.sigs.k8s.io/api-types/gatewayclass) |
| [Gateway](#kind-gateway) | Describes how traffic can be translated to Services within the cluster | [Gateway](https://gateway-api.sigs.k8s.io/api-types/gateway) |
| [HTTPRoute](#kind-httproute) | HTTP rules for mapping requests from a Gateway to Kubernetes Services | [Route](https://gateway-api.sigs.k8s.io/api-types/httproute) |
| [TCPRoute](#kind-tcproute) | Allows mapping TCP requests from a Gateway to Kubernetes Services | [Route](https://gateway-api.sigs.k8s.io/guides/tcp/) |
| [TLSRoute](#kind-tlsroute) | Allows mapping TLS requests from a Gateway to Kubernetes Services | [Route](https://gateway-api.sigs.k8s.io/guides/tls/) |
### Kind: `GatewayClass`
`GatewayClass` is cluster-scoped resource defined by the infrastructure provider. This resource represents a class of
Gateways that can be instantiated. More details on the
GatewayClass [official documentation](https://gateway-api.sigs.k8s.io/api-types/gatewayclass/).
The `GatewayClass` should be declared by the infrastructure provider, otherwise please register the `GatewayClass`
[definition](../../reference/dynamic-configuration/kubernetes-gateway.md#definitions) in the Kubernetes cluster before
creating `GatewayClass` objects.
!!! info "Declaring GatewayClass"
```yaml
```yaml tab="GatewayClass"
---
apiVersion: gateway.networking.k8s.io/v1
kind: GatewayClass
metadata:
name: my-gateway-class
name: traefik
spec:
# Controller is a domain/path string that indicates
# the controller that is managing Gateways of this class.
controllerName: traefik.io/gateway-controller
```
### Kind: `Gateway`
Next, the following `Gateway` manifest configures the running Traefik controller to handle the incoming traffic.
A `Gateway` is 1:1 with the life cycle of the configuration of infrastructure. When a user creates a Gateway, some load
balancing infrastructure is provisioned or configured by the GatewayClass controller. More details on the
Gateway [official documentation](https://gateway-api.sigs.k8s.io/v1alpha2/api-types/gateway/).
!!! info "Listener ports"
Register the `Gateway` [definition](../../reference/dynamic-configuration/kubernetes-gateway.md#definitions) in the
Kubernetes cluster before creating `Gateway` objects.
Please note that `Gateway` listener ports must match the configured [EntryPoint ports](../entrypoints.md) of the Traefik deployment.
In case they do not match, an `ERROR` message is logged, and the resource status is updated accordingly.
Depending on the Listener Protocol, different modes and Route types are supported.
| Listener Protocol | TLS Mode | Route Type Supported |
|-------------------|----------------|--------------------------------------------------------|
| TCP | Not applicable | [TCPRoute](#kind-tcproute) |
| TLS | Passthrough | [TLSRoute](#kind-tlsroute), [TCPRoute](#kind-tcproute) |
| TLS | Terminate | [TLSRoute](#kind-tlsroute), [TCPRoute](#kind-tcproute) |
| HTTP | Not applicable | [HTTPRoute](#kind-httproute) |
| HTTPS | Terminate | [HTTPRoute](#kind-httproute) |

Once a `Gateway` is deployed (see [Deploying a Gateway](#deploying-a-gateway)) `HTTPRoute`, `TCPRoute`,
and/or `TLSRoute` resources must be deployed to forward some traffic to Kubernetes backend [services](https://kubernetes.io/docs/concepts/services-networking/service/).

### Kind: `HTTPRoute`
As demonstrated in the following examples, a Route resource must be configured with `ParentRefs` that reference the parent `Gateway` it should be associated with.
`HTTPRoute` defines HTTP rules for mapping requests from a `Gateway` to Kubernetes Services.
### HTTP/HTTPS
Register the `HTTPRoute` [definition](../../reference/dynamic-configuration/kubernetes-gateway.md#definitions) in the
Kubernetes cluster before creating `HTTPRoute` objects.
The `HTTPRoute` is a core resource in the Gateway API specification, designed to define how HTTP traffic should be routed within a Kubernetes cluster.
It allows the specification of routing rules that direct HTTP requests to the appropriate Kubernetes backend services.
!!! info "Declaring HTTPRoute"
For more details on the resource and concepts, check out the Kubernetes Gateway API [documentation](https://gateway-api.sigs.k8s.io/api-types/httproute/).
```yaml
For example, the following manifests configure a whoami backend and its corresponding `HTTPRoute`,
reachable through the [deployed `Gateway`](#deploying-a-gateway) at the `http://whoami.localhost` address.

## Using Traefik middleware as HTTPRoute filter
An HTTP [filter](https://gateway-api.sigs.k8s.io/api-types/httproute/#filters-optional) is an `HTTPRoute` component which enables the modification of HTTP requests and responses as they traverse the routing infrastructure.
There are three types of filters:
- **Core:** Mandatory filters for every Gateway controller, such as `RequestHeaderModifier` and `RequestRedirect`.
- **Extended:** Optional filters for Gateway controllers, such as `ResponseHeaderModifier` and `RequestMirror`.
- **ExtensionRef:** Additional filters provided by the Gateway controller. In Traefik, these are the [HTTP middlewares](https://doc.traefik.io/traefik/middlewares/http/overview/) supported through the [Middleware CRD](../providers/kubernetes-crd.md#kind-middleware).
!!! info "ExtensionRef Filters"
To use Traefik middlewares as `ExtensionRef` filters, the Kubernetes IngressRoute provider must be enabled in the static configuration, as detailed in the [documentation](../../providers/kubernetes-crd.md).
For example, the following manifests configure an `HTTPRoute` using the Traefik `AddPrefix` middleware,
reachable through the [deployed `Gateway`](#deploying-a-gateway) at the `http://whoami.localhost` address:
```yaml tab="HTTRoute"
