kubernetes - Minikube入口未响应

Question

我无法使用minikube在本地计算机上运行Minikube Nginx Ingress。它只是超时。
我关注了this教程和this one。

Minikube版本:

v1.8.1 (commit cbda04cf6bbe65e987ae52bb393c10099ab62014)

集群信息:

}

我的本地环境一定有问题，但是我不知道如何调试它。到目前为止，这是我当前的环境:

迷你库IP

~\Desktop\kubernetes> minikube IP
172.17.186.182

Answer 1

您正在Service定义中使用ClusterIP，从输出的外观看，您正在Windows上运行minikube。

从Windows CMD您将无法获得ClusterIP，因为它在VM(虚拟机)中运行。您可以通过运行以下命令来确认:

minikube ssh

然后在VM中:

curl 172.17.186.182

您可以尝试在VM上使用 NodePort 公开服务。这将是您的VM外部可用的端口，但由于Kubernetes分配了 30000-32767的可配置范围，所以不会是80。您可以根据需要使用 --service-node-port-range portRange选项在 kube-apiserver中手动更改此设置。

apiVersion: v1
kind: Service
metadata:
  name: hello-kubernetes-first
spec:
  type: NodePort
  ports:
  - port: 80
    targetPort: 8080
    name: http
  selector:
    app: hello-kubernetes-first

从Windows CMD中获取 NodePort(示例):

kubectl get svc
NAME                     TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
hello-kubernetes-first   NodePort    10.102.234.222   <none>        80:31181/TCP   3m51s
kubernetes               ClusterIP   10.96.0.1        <none>        443/TCP        138d

上面的NodePort是 31181
接下来，您必须在虚拟机中为eth0使用IP:

minikube ssh
$ ifconfig eth0

然后回到您的Windows CMD:

curl <ip-from-eth0-above>:31181
