Minikube IP和入口地址不同。如何访问通过Ingress路由的服务

Question

Minikube部署在EC2实例中。Kubernetes dashboard作为群集ip服务部署在Minikube中

Nginx-Ingress-Controller作为NodePort服务部署。入口YAML文件如下：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  namespace: kubernetes-dashboard
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/ssl-passthrough: "true"
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
    nginx.ingress.kubernetes.io/use-regex: "true"
    nginx.ingress.kubernetes.io/rewrite-target: "/$1"
  name: ingress-resource
spec:
  rules:
   - http:
      paths:
      - path: /kubedashboard
        pathType: Prefix
        backend:
          service:
            name: kubernetes-dashboard
            port:
              number: 443

入口地址为：

Minikube IP为：

Minikube IP和入口地址不同。我没有提到Ingress.yaml中的任何主机。

入口和Kubernetes仪表板部署在同一个命名空间中: kubernetes-dashboard。

如何通过Ingress访问kubernetes仪表板？

我想通过以下方式访问：

curl https://localhost:NodePort/kubedashboard --insecure

或

curl https://MinikubeIP:NodePort/kubedashboard --insecure

或

curl https://EC2PublicIP:NodePort/kubedashboard --insecure

Answer 1

不需要入口，ingress只用于80和443端口，如果要使用节点端口访问仪表板，只需将仪表板服务类型设置为NodePort即可。

然后，您应该能够使用curl https://localhost:NodePort/ --insecure进行访问

kubectl patch service kubernetes-dashboard -n kubernetes-dashboard -p '{"spec": {"type": "NodePort"}}'
kubectl get service kubernetes-dashboard -n kubernetes-dashboard

如果你真的想使用入口。使用下面的入口，然后您可以从https://localhost/kubedashboard/访问

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: kubernetes-dashboard
  annotations:
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
    nginx.ingress.kubernetes.io/rewrite-target: /$2
    nginx.ingress.kubernetes.io/configuration-snippet: |
      rewrite ^(/kubedashboard)$ $1/ redirect;
  namespace: kubernetes-dashboard
spec:
  ingressClassName: nginx
  rules:
  - http:
      paths:
      - path: /kubedashboard(/|$)(.*)
        pathType: ImplementationSpecific
        backend:
          service:
            name: kubernetes-dashboard
            port:
              number: 443
