Similar to traefik/traefik#11666

On microk8s 1.32.3 I get

W0412 00:27:21.933731       1 reflector.go:561] k8s.io/[email protected]/tools/cache/reflector.go:243: failed to list *v1.GRPCRoute: the server could not find the requested resource (get grpcroutes.gateway.networking.k8s.io)
E0412 00:27:21.933765       1 reflector.go:158] "Unhandled Error" err="k8s.io/[email protected]/tools/cache/reflector.go:243: Failed to watch *v1.GRPCRoute: failed to list *v1.GRPCRoute: the server could not find the requested resource (get grpcroutes.gateway.networking.k8s.io)" logger="UnhandledError"

We have no mention of GRPCRoute anywhere. This is just with gateway created on an otherwise empty cluster with this

kubectl apply -f - <<EOF
apiVersion: gateway.networking.k8s.io/v1
kind: GatewayClass
metadata:
  name: traefik
spec:
  controllerName: traefik.io/gateway-controller
EOF

What did you see instead?

Sadness and lack of joy.

What version of Traefik are you using?

Chart: traefik-35.0.0 App: v3.3.5

What is your environment & configuration?

Hello @edgework,

The issue seems to be linked to the helm chart, I move this issue to the helm-chart repository.

[mloiseleur]

This section is invalid:

microk8s kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.0.0/standard-install.yaml
microk8s kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.0.0/experimental-install.yaml

See upstream documentation for valid version. There is no need for you to do this, the correct CRDs are already in the chart (source)

BTW, this value does not exist:

providers:
  kubernetesGateway:
    disableGRPCRoute: true

There is a complete Gateway API example, see here.

Does that answer your question ?
