一.存储卷(Volume)概述
1>.什么是存储卷
熟悉Docker架构的同学，想必说到存储卷大家应该都很熟悉了，其实在功能上K8S的存储卷和Docker功能类似,Docker是为了持久化Container容器的数据，而K8S则是为了持久化Pods中的数据。
由于在一个节点上所有的容器是共享宿主机内核的，而驱动是属于内核的。因此K8s node主机内核需要适配目标存储系统,否则该K8s node主机中的Pod将无法使用目标存储系统(如你们公司自己研发的存储系统)。
虽然K8S已经内置了很多常用的标准类型存储系统驱动，但对于自研的存储系统需要满足Google定义的CSI(Container Storage Interface)规范:
利用CSI用户可以方便开发自己的Pods存储驱动插件,可以自定义使用任何的类型的存储系统插件。

3>.使用存储卷(Volumes)的注意事项
在Kerbernetes集群的Pod上想要使用存储卷(Volumes)，需要注意以下事项:
(1)确保外部存储系统(Storage System)可用;
(2)需要在Pod级别指明存储系统的存储服务作为存储卷在当前Pod中使用(此时存储卷只是将"k8s.gcr.io/pause"这个Pod作为存储系统的客户端);
(3)之后，在该Pod中的容器上挂载该存储卷(如果此步骤不做，尽管你做了第二步容器也无法使用存储卷，因为在该容器中没有挂载点)
二.本地存储卷(hostPath)使用案例(挂在node节点本地的目录)
1>.编写支持hostPath的存储卷使用案例(参考文档:https://kubernetes.io/docs/concepts/storage/volumes/#hostpath)

3>.优化hostPath方案
hostPath存在的风险剖析:
当我们手动删除Pod时,如果新建的Pod不在之前的那台k8s node主机上，则数据全部丢失，因此我们可以绑定Pod在某一台k8s node主机上，这样新建的Pod数据还是可以在该主机上获取到。
综上所述,我们可以总结为hostPath只能维持节点的数据存储的持久性，当节点宕机时数据依旧是访问不了啦，而且Pod只能被调度到拥有相同数据的node主机。
优化hostPath方案1:
我们将web数据在所有K8S node主机上使用rsync同步一份数据到其它节点,这样无论Pod被调度到K8s集群的任何一台服务器数据都不会丢失，但是该方案有个很明显的缺点就是浪费存储空间。
优化hostPath方案2:
我们可以使用分布式存储系统，然后在K8s node主机上配置上挂载，这样被写入的数据虽说是本地的存储目录，但实际上缺存储到分布式文件系统上了,相比上一种解决方案更加节省空间，而且还可以借助存储系统本身的可用性保证数据不丢失。
优化hostPath方案3:
就是直接在编辑Pod的yaml文件时指定每次启动该容器时只能(绑定)运行在某一台节点上，这样每次启动数据时数据均不会丢失，该方案很明显的缺陷就是当该节点宕机时，则Pod长时间无法完成调度。
4>.另一种本地存储卷(local)方案(参考文档:https://kubernetes.io/docs/concepts/storage/volumes/#local)
三.临时存储卷(emptyDir)使用案例(一般用作缓存空间)
1>. 编写支持hostPath的存储卷使用案例(参考文档:https://kubernetes.io/docs/concepts/storage/volumes/#emptydir)
[root@master200.yinzhengjie.org.cn ~]# kubectl explain pods.spec.volumes.emptyDir KIND: Pod VERSION: v1 RESOURCE: emptyDir <Object> DESCRIPTION: EmptyDir represents a temporary directory that shares a pod's lifetime.

FIELDS: medium <string> What type of storage medium should back this directory. The default is "" which means to use the node's default medium. Must be an empty string (default) or Memory. More info: https://kubernetes.io/docs/concepts/storage/volumes#emptydir sizeLimit <string> Total amount of local storage required for this EmptyDir volume. The size limit is also applicable for memory medium. The maximum usage on memory medium EmptyDir would be the minimum value between the SizeLimit specified here and the sum of memory limits of all containers in a pod.
