我是Kubernetes的新手。我正在学习一个教程，我需要在kuberenetes集群中运行一个服务。运行minikube start后，得到以下输出：

> 😄  minikube v1.29.0 on Ubuntu 20.04 (vbox/amd64) ✨  Automatically
> selected the docker driver. Other choices: none, ssh 📌  Using Docker

然后分别运行kubectl apply -f client-node-port.yaml和kubectl apply -f client-pod.yaml。
client-node-port.yaml看起来像这样：

apiVersion: v1
kind: Service
metadata:
  name: client-node-port
spec:
  type: NodePort
  ports:
    - port: 3050
      targetPort: 3001
      nodePort: 31515
  selector: 
    component: web

client-pod.yaml文件看起来像这样：

apiVersion: v1
kind: Pod
metadata:
  name: client-pod
  labels:
    component: web
spec:
  containers:
    - name: client
      image: dibyajyoti47/multi-client
      ports:
        - containerPort: 3001
      imagePullPolicy: Always

然后运行命令minikube ip，输出为192.168.49.2。之后，我去浏览器与url 192.168.49.2:31515得到拒绝连接。
我错过了什么吗？请帮助我解决此问题。先谢谢你了。
注意：我在“Windows 10”机器上的“Oracle VM虚拟机”中运行“Ubuntu 20”。
