测试gateway api 不成功

[alexzzh]

按照 https://zhuanlan.zhihu.com/p/679799511 文档所述，测试higress gateway api资源效果:

• gatewayclass.yaml

apiVersion: gateway.networking.k8s.io/v1
kind: GatewayClass
metadata:
  name: higress-gateway
spec:
  controllerName: "higress.io/gateway-controller"

• gateway.yaml

apiVersion: gateway.networking.k8s.io/v1
kind: Gateway
metadata:
  name: higress-gateway
  namespace: higress-system
spec:
  gatewayClassName: higress-gateway
  listeners:
    - name: foobar
    hostname: "*.foobar.com"
    port: 22222
    protocol: HTTP
    allowedRoutes:
      namespaces:
        from: All

• httproute.yaml

apiVersion: gateway.networking.k8s.io/v1
kind: HTTPRoute
metadata:
  name: foobar
  namespace: default
spec:
  parentRefs:
  - name: higress-gateway
    namespace: higress-system
  hostnames: ["www.foobar.com"]
  rules:
  - matches:
    - path:
        type: PathPrefix
        value: /foo
    backendRefs:
    - name: foo-service
      port: 5678

• apply都是ok的

kubectl apply -f gatewayclass.yaml
gatewayclass.gateway.networking.k8s.io/higress-gateway created
kubectl  apply -f gateway.yaml
gateway.gateway.networking.k8s.io/higress-gateway created
kubectl apply -f httproute.yaml
httproute.gateway.networking.k8s.io/foobar created

• 查看higress-gateway监听的端口并没有 22222， 肯定访问不成功

hgctl gateway-config listener | grep  22222

$ curl http://192.168.49.2:22222/foo -H "Host: www.foobar.com"
curl: (7) Failed to connect to 192.168.49.2 port 22222: Connection refused

• 查看gateway资源状态，有点异常, 但不清楚怎么回事?

$ kubectl describe  gateway higress-gateway  -n higress-system

“failed to assign to any requested addresses: port 22222 not found for hostname "higress-gateway.higress-system.svc.cluster.local"

根据这条错误信息，在svc增加了对应端口，已能正常访问
