Kubernetes：通过入口路由Kubernetes仪表板，主机输出，没有代理

Question

有人能帮我走台阶吗...（我在互联网的帮助下尝试了多种方法...不知道我错过了什么？）

注意：根据讨论论坛，我在ingress YAML的部署部分中添加了“hostnetwork：true”来解决“没有主机参数不能工作”，并注释了“type：nodeport”。

更新信息：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: nginx-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
    - http:
        paths:
        - path: /
          pathType: Prefix
          backend:
            service:
              name: kdash-in-ns
          port:
            number: 443

kind: Service
apiVersion: v1
metadata:
  name: kdash-in-ns
  namespace: default
spec:
  type: ExternalName
  externalName: kubernetes-dashboard.kubernetes-dashboard.svc.cluster.local
  ports:

    port: 443

dockeras@ubuntu3:~/simplek8s/kubernetes/yamls/ingress-demo$ kubectl describe svc kdash-in-ns
Name:              kdash-in-ns

kubectl描述了更新后的入口路由：在这里，我有ngnix--它工作得很好（我猜ingress和nginx都在相同的命名空间中...仪表板的geting错误--因为它在不同的命名空间（kubernetes-dasbhoard））

当我在浏览器中尝试相同的URL时，以下是响应（我的工作人员之一IP-192.168.1.31)

如果我理解正确的话，您希望从集群外部访问kubernetes服务（仪表板）。您可以部署metallb LoadBalancer并管理从外部集群网络分配给您的集群的IPs。

因此，您可以分配一个IP和一个LoadBalancer来访问您的服务。下面是mssql server的一个示例，但您可以通过仪表板轻松地使其适应您的需要：

apiVersion: v1
kind: Service
metadata:
  name: sql-server-lb
  namespace: database-server
  annotations:
    metallb.universe.tf/address-pool: default
spec:
  selector:
    app: sql-server
  ports:
  - port: 1433
    targetPort: 1433
  type: LoadBalancer
