我似乎找不到为什么无法连接到我通过NodePort公开的端点。当运行kubectl logs <pod>时，容器按预期运行，我无法访问：
http://<node ip>:30100/<valid endpoint form container>
其中<node ip>是在INTERNAL IP下运行kubectl get nodes -o wide的ip。
我不确定问题是否存在于部署yaml中。下面是我应用到集群的单个部署：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: auth-app-deployment
  labels:
    app: auth-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: auth-app
  template:
    metadata:
      labels:
        app: auth-app
    spec:
      containers:
        - name: auth-app
          image: <working image>
          ports:
            - containerPort: 80

---
apiVersion: v1
kind: Service
metadata:
  name: auth-app-service
spec:
  type: NodePort
  selector:
    app: auth-app
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80
      nodePort: 30100

下面是运行kubectl get all的结果：

NAME                                       READY   STATUS    RESTARTS   AGE

PS：我用的是minikube。
