概要
statefulset应用是有状态并且数据有强关联性，多副本之间不能共用一个存储盘，所以每个副本需要一个单独的存储盘；通常情况下为多副本的statefulset设置持久化存储需要使用到Dynamic Provisioning，可以理解为需要一个StorageClass 存储；在openshift3.11 prometheus的管理由operator管理，也就是会使用到statefulset；Dynamic Provisioning对存储的要求较高，有些客户那里并没有支持Dynamic Provisioning的存储，其实NFS也是支持Dynamic Provisioning的，但是这个需要openshift对接到NFS存储管理层面，意味着openshift自己去NFS存储上创建NFS卷，但是这个在大部分客户那里是无法接受提供这么高的管理权限给openshift；通常情况下客户的存储负责人那里提供一个比较大的NFS卷给到openshift，openshift自行规划使用。基于上述原因我要给operator 管理 statefulset (prometheus) 多副本配置持久化存储只能使用客户提供好的nfs盘，在里面自己创建应用目录进行使用了。
通常情况下定义statefulset多副本的yml文件
创建了这个statefulset后，会自动的去找能够使用的storageclass创建PVC/PV，然后挂载至对应的pod上。

默认openshift未对prometheus进行持久化statefulset的yml文件
可以看到prometheus的volume字段是空的，未进行持久化。

- yml文件
可以看到volume字段的prometheus-k8s-db没了，多了个volumeClaimTemplates字段。
