我为 SpringBoot-Java-App 创建了一个带有部署 + 服务 (LoadBalancer) 的 Kubernetes 集群。如果我想通过外部 IP 访问 Web-App，我会收到超时错误。现在有人如何解决这个问题吗？

LoadBalancerService.yml：

apiVersion: v1
kind: Service
metadata:
  creationTimestamp: null
  labels:
    app: webapp
  name: webapp
spec:
  ports:
  - name: 8080-8080
    port: 8080
    protocol: TCP
    targetPort: 8080
  selector:
    app: webapp
  type: LoadBalancer

部署.yml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: webapp
  labels:
    app: webapp
spec:
  replicas: 4
  selector:
    matchLabels:
      app: webapp
  template:
    metadata:
      labels:
        app: webapp
    spec:
      containers:
        - name: webapp-container
          image: skrivutenliv/raspi_stress:latest
          ports:
        - containerPort: 8080
