Windows10 上无法通过 NodePort 或 ClusterIP 访问 Minikube 服务

Question

我正在 Windows10 机器上的本地 minikube 集群上测试一些东西。我在我的本地 minikube 集群上部署了我的测试部署并向其添加了一个服务以通过 NodePort 访问它，但我无法访问它。

PS C:\Users\Admin> kubectl get all -n web -o wide

PS C:\Users\Admin> kubectl describe svc nginx-webserver-service -n web

External Traffic Policy:  Cluster

但是我无法使用 nodeport 方法连接：

PS C:\Users\Admin> curl 10.96.115.194:30008
curl : Unable to connect to the remote server
At line:1 char:1
+ curl 10.96.115.194:30008

    + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-WebRequest], WebException
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

我尝试完全禁用 Windows 防火墙，但没有成功。

我一定是遗漏了一些核心但还没有弄清楚的东西。

我找到了解决方案。

与 Linux 不同，在 Windows10.

上使用服务定义 yaml 文件上的指定端口访问 NodePort 并不是一件简单的事情

在 Windows10 上，必须按如下方式完成：

PS C:\Users\Admin> minikube service nginx-webserver-service -n web
|-----------|-------------------------|-------------|---------------------------|
| NAMESPACE |          NAME           | TARGET PORT |            URL            |
|-----------|-------------------------|-------------|---------------------------|
| web       | nginx-webserver-service | http/80     | http://192.168.49.2:30008 |
|-----------|-------------------------|-------------|---------------------------|
* Starting tunnel for service nginx-webserver-service.
|-----------|-------------------------|-------------|------------------------|
| NAMESPACE |          NAME           | TARGET PORT |          URL           |
|-----------|-------------------------|-------------|------------------------|
| web       | nginx-webserver-service |             | http://127.0.0.1:61410 |
|-----------|-------------------------|-------------|------------------------|
* Opening service web/nginx-webserver-service in default browser...
! Because you are using a Docker driver on windows, the terminal needs to be open to run it.
* Stopping tunnel for service nginx-webserver-service.

这将在您的默认网络浏览器上自动打开公开的服务。

否则，您可以让它直接生成 URL 而不是自动打开。

PS C:\Users\Admin> minikube service nginx-webserver-service -n web --url
* Restarting the docker service may improve performance.
* Starting tunnel for service nginx-webserver-service.
|-----------|-------------------------|-------------|------------------------|
| NAMESPACE |          NAME           | TARGET PORT |          URL           |
|-----------|-------------------------|-------------|------------------------|
| web       | nginx-webserver-service |             | http://127.0.0.1:52665 |
|-----------|-------------------------|-------------|------------------------|
http://127.0.0.1:52665
! Because you are using a Docker driver on windows, the terminal needs to be open to run it.
* Stopping tunnel for service nginx-webserver-service.
