Dynamic provisioning eliminates the need for cluster administrators to pre-provision storage. Instead, it automatically provisions storage by user request. Dynamic volume provisioning is based on an API object, {{< glossary_tooltip text="StorageClass" term_id="storage-class" >}}, referring to a {{< glossary_tooltip text="Volume Plugin" term_id="volume-plugin" >}} that provisions a {{< glossary_tooltip text="Volume" term_id="volume" >}} and the set of parameters to pass to the Volume Plugin.

动态制备让集群管理员无需再预先制备存储。这种机制转为通过用户请求自动地制备存储。
动态卷制备是基于 API 对象 {{< glossary_tooltip text="StorageClass" term_id="storage-class" >}} 的，
StorageClass 可以引用{{< glossary_tooltip text="卷插件（Volume Plugin）" term_id="volume-plugin" >}}
提供的{{< glossary_tooltip text="卷" term_id="volume" >}}，
也可以引用传递给卷插件的参数集。
