    volumeMounts:
    - name: data01
      # 指定挂载点，若不指定subPath属性，则挂载点默认为目录。若指定后，可以让挂载点对应的是一个文件。
      mountPath: /etc/nginx/nginx.conf
      # 指定subPath，声明其在挂载点的文件名称。要和"po.spec.volumes.configMap.items.path"相同。
      # subPath: nginx.conf
      subPath: haha
      # 声明只读(ro)权限，默认是读写(rw)
      readOnly: true
    - name: data02
      mountPath: /etc/nginx/conf.d/
