<!--
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.

动态供应让集群管理员无需再预先供应存储。相反，它通过用户请求自动地供应存储。
动态卷供应是基于 API 对象 {{< glossary_tooltip text="StorageClass" term_id="storage-class" >}} 的，
StorageClass 可以引用 {{< glossary_tooltip text="卷插件" 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（Volume Plugin）的参数集。
