[Gateway API] Unable to get listener to attach!

Help!
1

Hi everybody,

I’ve been trying to get my listener to attach to my Gateway in kubernetes, and I just can’t get it to work! Here’s what I’ve written till now:

apiVersion: gateway.networking.k8s.io/v1alpha2
kind: GatewayClass
metadata:
  namespace: bind9
  name: bind9-gatewayclass
spec:
  controllerName: haproxy.org/gateway-controller

apiVersion: gateway.networking.k8s.io/v1alpha2
kind: Gateway
metadata:
  name: bind9-gateway
  namespace: bind9
spec:

  listeners:
    - allowedRoutes:
        kinds:
          - group: gateway.networking.k8s.io
            kind: TCPRoute
        namespaces:
          from: All
      name: bind9-dns-listener
      port: 53
      protocol: TCP

apiVersion: gateway.networking.k8s.io/v1alpha2

    - backendRefs:
        - group: ""
          kind: Service
          name: bind9-dns-service
          port: 53

        image: ubuntu/bind9:edge  # Use a pre-built BIND9 image
        ports:
        - containerPort: 53
          protocol: TCP
        args:
        - "/usr/sbin/named"
        - "-g"  # Start BIND9 in the foreground
        - "-c"
        - "/etc/bind/named.conf"

Sorry to make you go through such a long file, but any help would be greatly appreciated! The error message is:

$ kubectl describe gateway bind9-gateway -n bind9
