Minikube入口没有响应

Question

我无法使用Minikube在本地机器上运行Minikube-Nginx-Ingress。它只是超时。我遵循了这个教程和这个教程。

Minikube版本：

v1.8.1 (commit cbda04cf6bbe65e987ae52bb393c10099ab62014)

集群信息：

我的本地环境肯定有问题，但我不知道如何调试它。这就是我目前的环境：

minikube IP

~Desktopkubernetes> minikube IP
172.17.186.182

Answer 1

您在服务定义中使用ClusterIP，从输出的外观来看，您正在Windows上运行minikube。

从您的Windows CMD，您将无法访问ClusterIP，因为它在VM(虚拟机(中运行。您可以通过运行来确认这一点

minikube ssh

然后在VM中：

curl 172.17.186.182

您可以尝试在虚拟机上使用NodePort公开您的服务。这将是一个从VM外部可用的端口，但它不会是80，因为Kubernetes分配了30000-32767的可配置范围。如果愿意的话，可以在kube-apiserver中使用--service-node-port-range portRange选项手动更改。

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VM中使用eth0的IP：

minikube ssh
$ ifconfig eth0

然后回到您的Windows CMD:

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

Answer 2

检查入口插件是否已启用：

minikube addons list

如果没有，启用它：

minikube addons enable ingress
