# Route
|
|
|
|
Routes are independent configuration objects that are associated with specific listeners.
|
|
|
|
Declare a route with either `kind: HTTPRoute` or `kind: TCPRoute` and configure the route parameters in the `spec` block.
|
|
Refer to the Kubernetes Gateway API documentation for each object type for details:
|
|
|
|
- [HTTPRoute](https://gateway-api.sigs.k8s.io/v1alpha2/references/spec/#gateway.networking.k8s.io/v1alpha2.HTTPRoute)
|
|
- [TCPRoute](https://gateway-api.sigs.k8s.io/v1alpha2/references/spec/#gateway.networking.k8s.io/v1alpha2.TCPRoute)
|
|
|
|
The following example creates a route named `example-route` associated with a listener defined in `example-gateway`.
|
|
|
|
<CodeBlockConfig filename="routes.yaml">
|
|
|
|
```yaml
|
|
apiVersion: gateway.networking.k8s.io/v1alpha2
|
|
kind: HTTPRoute
|
|
metadata:
|
|
name: example-route
|
|
spec:
|
|
parentRefs:
|
|
- name: example-gateway
|
|
rules:
|
|
- backendRefs:
|
|
- kind: Service
|
|
name: echo
|
|
port: 8080
|
|
```
|
|
|
|
</CodeBlockConfig>
|
|
|
|
To create a route for a `backendRef` in a different namespace, you must also
|
|
create a [ReferencePolicy](https://gateway-api.sigs.k8s.io/v1alpha2/references/spec/#gateway.networking.k8s.io/v1alpha2.ReferencePolicy).
|
|
|
|
The following example creates a route named `example-route` in namespace `gateway-namespace`. This route has a `backendRef` in namespace `service-namespace`. Traffic is allowed because the `ReferencePolicy`, named `reference-policy` in namespace `service-namespace`, allows traffic from `HTTPRoutes` in `gateway-namespace` to `Services` in `service-namespace`.
|
|
|
|
<CodeBlockConfig filename="route_with_referencepolicy.yaml">
|
|
|
|
```yaml
|
|
apiVersion: gateway.networking.k8s.io/v1alpha2
|
|
kind: HTTPRoute
|
|
metadata:
|
|
name: example-route
|
|
namespace: gateway-namespace
|
|
spec:
|
|
parentRefs:
|
|
- name: example-gateway
|
|
rules:
|
|
- backendRefs:
|
|
- kind: Service
|
|
name: echo
|
|
namespace: service-namespace
|
|
port: 8080
|
|

|
|
|
|
apiVersion: gateway.networking.k8s.io/v1alpha2
|
|
kind: ReferencePolicy
|
|
metadata:
|
|
name: reference-policy
|
|
namespace: service-namespace
|
|
spec:
|
|
from:
|
|
- group: gateway.networking.k8s.io
|
|
kind: HTTPRoute
|
|
namespace: gateway-namespace
|
|
to:
|
|
- group: ""
|
|
kind: Service
|
|
name: echo
|
|
```
|
|
|
|
</CodeBlockConfig>
|

|
## MeshService
|
|
|
|
The `MeshService` configuration holds a reference to an externally-managed Consul service mesh service and can be used as a `backendRef` for a [`Route`](#route).
|
|
|
|
| Parameter | Description | Type | Default |
|
|
| ------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | --------------- |
|
|
| `name` | Specifies the service name for a Consul service. It is assumed this service will exist in either the `consulDestinationNamespace` or mirrored Consul namespace from where this custom resource is defined, depending on the Helm configuration.
|
|
|
|
Refer to the [Consul API Gateway repository](https://github.com/hashicorp/consul-api-gateway/blob/main/config/crd/bases/api-gateway.consul.hashicorp.com_meshservices.yaml) for the complete specification.
