k8s使用ingress代理非集群ip地址

Question

我有一个web服务，没有在集群中，想使用 ingress 代理

下面是我的 yaml 文件

apiVersion: v1
kind: Service
metadata:
  name: exsi-web
spec:
  ports:
    - name: http
      port: 80
      protocol: TCP
      targetPort: 443
  type: ClusterIP
---
apiVersion: v1
kind: Endpoints
metadata:
  name: exsi-web
subsets:
  - addresses:
      - ip: 192.168.1.102
    ports:
      - name: https
        port: 443
        protocol: TCP
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: esxi-web
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
    - host: exsi.mrj.com
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: exsi-web
                port:
                  number: 443

但是却报错

  ~ k describe ing esxi-web
Name:             esxi-web
Namespace:        default
Address:
Default backend:  default-http-backend:80 (<error: endpoints "default-http-backend" not found>)

  Normal  AddedOrUpdated  22m   nginx-ingress-controller  Configuration for default/esxi-web was added or updated

问题：

1. 需要如何修改 ingress 的配置，才能正确发现 endpoint ?
