我对k8s相对来说是个新手，为了熟悉它，我跟随了tutorial。有一个通过ingress暴露kubernetes-dashboard的例子，我尝试了一下。
通过运行以下命令配置kubernetes-dashboard。根据documentation。kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.6.1/aio/deploy/recommended.yaml
但与教程kubernetes不同的是--dashboard是通过端口443暴露的

service/dashboard-metrics-scraper   ClusterIP   10.108.119.138   <none>        8000/TCP   50m
service/kubernetes-dashboard        ClusterIP   10.100.58.17     <none>        443/TCP    50m

因此我相应地更改了入口配置yaml。

apiVersion: networking.k8s.io/v1 
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
  name: ingress-dashboard
  namespace: kubernetes-dashboard
spec: 
  rules:
  - host: k8s-dashboard.com
    http:
      paths:
      - pathType: Prefix
        path: /
        backend:
          service:
            name: kubernetes-dashboard
            port: 
              number: 443

然后，我描述了入口并获取IP，并在/etc/hosts中为其添加了一个条目

kubectl describe ingress ingress-dashboard -n kubernetes-dashboard
Name:             ingress-dashboard
Labels:           <none>

                     nginx.ingress.kubernetes.io/backend-protocol: HTTPS

  Normal  Sync    24m (x2 over 25m)  nginx-ingress-controller  Scheduled for sync

/etc/hosts更改

192.168.49.2    k8s-dashbaord.com

当试图访问k8s-dashbaord.com时。404 Not Found从nginx找不到因此，它看起来像ingress正在运行，但它无法到达服务。
Map到ingress规则的ip似乎是错误的。（172.17.0.6：8443）。因为这不是服务的IP。
我做错了什么？
P.S.
如果我只是一个代理（kubectl代理）和访问 Jmeter 板，它工作得很好。
