<h1 id="kubernetes存储卷">Kubernetes存储卷</h1>
|
||
|
|
<p>我们知道默认情况下容器的数据都是非持久化的，在容器消亡以后数据也跟着丢失，所以Docker提供了Volume机制以便将数据持久化存储。类似的，Kubernetes提供了更强大的Volume机制和丰富的插件，解决了容器数据持久化和容器间共享数据的问题。</p>
|
||
|
|
<h2 id="volume">Volume</h2>
|
||
|
|
<p>目前，Kubernetes支持以下Volume类型：</p>
|
||
|
|
<ul>
|
||
|
|
<li>emptyDir</li>
|
||
|
|
<li>hostPath</li>
|
||
|
|
<li>gcePersistentDisk</li>
|
||
|
|
<li>awsElasticBlockStore</li>
|
||
|
|
<li>nfs</li>
|
||
|
|
<li>iscsi</li>
|
||
|
|
<li>flocker</li>
|
||
|
|
<li>glusterfs</li>
|
||
|
|
<li>rbd</li>
|
||
|
|
<li>cephfs</li>
|
||
|
|
<li>gitRepo</li>
|
||
|
|
<li>secret</li>
|
||
|
|
<li>persistentVolumeClaim</li>
|
||
|
|
<li>downwardAPI</li>
|
||
|
|
<li>azureFileVolume</li>
|
||
|
|
<li>vsphereVolume</li>
|
||
|
|
<li>flexvolume</li>
|
||
|
|
</ul>
|
||
|
|
<p>注意，这些volume并非全部都是持久化的，比如emptyDir、secret、gitRepo等，这些volume会随着Pod的消亡而消失。</p>
|
||
|
|
<h2 id="persistentvolume">PersistentVolume</h2>
|
||
|
|
<p>对于持久化的Volume，PersistentVolume (PV)和PersistentVolumeClaim (PVC)提供了更方便的管理卷的方法：PV提供网络存储资源，而PVC请求存储资源。这样，设置持久化的工作流包括配置底层文件系统或者云数据卷、创建持久性数据卷、最后创建claim来将pod跟数据卷关联起来。PV和PVC可以将pod和数据卷解耦，pod不需要知道确切的文件系统或者支持它的持久化引擎。</p>
|
||
|
|
<h3 id="pv">PV</h3>
|
||
|
|
<p>PersistentVolume（PV）是集群之中的一块网络存储。跟 Node 一样，也是集群的资源。PV 跟 Volume (卷) 类似，不过会有独立于 Pod 的生命周期。比如一个NFS的PV可以定义为</p>

<p>PV的访问模式有三种：</p>
|
||
|
|
<ul>
|
||
|
|
<li>第一种，ReadWriteOnce：是最基本的方式，可读可写，但只支持被单个Pod挂载。</li>
|
||
|
|
<li>第二种，ReadOnlyMany：可以以只读的方式被多个Pod挂载。</li>
|
||
|
|
<li>第三种，ReadWriteMany：这种存储可以以读写的方式被多个Pod共享。不是每一种存储都支持这三种方式，像共享方式，目前支持的还比较少，比较常用的是NFS。在PVC绑定PV时通常根据两个条件来绑定，一个是存储的大小，另一个就是访问模式。</li>

<p>上面通过手动的方式创建了一个NFS Volume，这在管理很多Volume的时候不太方便。Kubernetes还提供了<a href="https://kubernetes.io/docs/user-guide/persistent-volumes/#storageclasses" target="_blank">StorageClass</a>来动态创建PV，不仅节省了管理员的时间，还可以封装不同类型的存储供PVC选用。</p>
