k8s中设置hostNetwork: true，怎么修改冲突的端口,yaml使用的是DaemonSet

apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: cadvisor
  namespace: monitoring
spec:
  selector:
    matchLabels:
      app: cAdvisor
  template:
    metadata:
      labels:
        app: cAdvisor
    spec:
      tolerations:    #污点容忍,忽略master的NoSchedule
        - effect: NoSchedule
          key: node-role.kubernetes.io/master
      hostNetwork: false
      restartPolicy: Always   # 重启策略
      containers:
      - name: cadvisor
        image: registry.zgshfp.com.cn/k8s/cadvisor:v0.39.2 
        imagePullPolicy: IfNotPresent  # 镜像策略
        ports:
        - containerPort: 8080
          hostPort: 8888 
        volumeMounts:
          - name: root
            mountPath: /rootfs
          - name: run
            mountPath: /var/run
          - name: sys
            mountPath: /sys
          - name: docker
            mountPath: /var/lib/docker
      volumes:
      - name: root
        hostPath:
          path: /
      - name: run
        hostPath:
          path: /var/run
      - name: sys
        hostPath:
          path: /sys
      - name: docker
        hostPath:
          path: /var/lib/docker
