3.2 网络优化配置

配置网络优化：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: edge-cache
spec:
  replicas: 1
  selector:
    matchLabels:
      app: edge-cache
  template:
    metadata:
      labels:
        app: edge-cache
    spec:
      containers:
      - name: edge-cache
        image: nginx:latest
        volumeMounts:
        - name: cache-volume
          mountPath: /usr/share/nginx/html
        resources:
          limits:
            cpu: "500m"
            memory: "512Mi"
          requests:
            cpu: "200m"
            memory: "256Mi"
        ports:
        - containerPort: 80
      volumes:
      - name: cache-volume
        emptyDir: {}
        

3.3 安全防护设置

配置安全防护：
