This document describes the concept of `VolumeSnapshotClass` in Kubernetes. Familiarity
|
||
with [volume snapshots](/docs/concepts/storage/volume-snapshots/) and
|
||
[storage classes](/docs/concepts/storage/storage-classes) is suggested.
|
||
-->
|
||
|
||
本文档描述了 Kubernetes 中 `VolumeSnapshotClass` 的概念。 建议熟悉[卷快照（Volume Snapshots）](/docs/concepts/storage/volume-snapshots/)和[存储类（Storage Class）](/docs/concepts/storage/storage-classes)。

## Introduction
|
||
|
||
Just like `StorageClass` provides a way for administrators to describe the "classes"
|
||
of storage they offer when provisioning a volume, `VolumeSnapshotClass` provides a
|
||
way to describe the "classes" of storage when provisioning a volume snapshot.
|
||
-->
|
||
|
||
## 介绍
|
||
|
||
就像 `StorageClass` 为管理员提供了一种在配置卷时描述存储“类”的方法，`VolumeSnapshotClass` 提供了一种在配置卷快照时描述存储“类”的方法。
|
||
|
||
<!--
|
||
## The VolumeSnapshotClass Resource
|
||
|
||
Each `VolumeSnapshotClass` contains the fields `snapshotter` and `parameters`,
|
||
which are used when a `VolumeSnapshot` belonging to the class needs to be
|
||
dynamically provisioned.
|
||
|
||
The name of a `VolumeSnapshotClass` object is significant, and is how users can
|
||
request a particular class. Administrators set the name and other parameters
|
||
of a class when first creating `VolumeSnapshotClass` objects, and the objects cannot
|
||
be updated once they are created.
|
||
|
||
Administrators can specify a default `VolumeSnapshotClass` just for VolumeSnapshots
|
||
that don't request any particular class to bind to.
|
||
-->
|
||
|
||
## VolumeSnapshotClass 资源
|
||
|
||
每个 `VolumeSnapshotClass` 都包含 `snapshotter` 和 `parameters` 字段，当需要动态配置属于该类的 `VolumeSnapshot` 时使用。
|
||
|
||
`VolumeSnapshotClass` 对象的名称很重要，是用户可以请求特定类的方式。
|
||
管理员在首次创建 `VolumeSnapshotClass` 对象时设置类的名称和其他参数，对象一旦创建就无法更新。
|
||
|
||
管理员可以为不请求任何特定类绑定的 VolumeSnapshots 指定默认的 `VolumeSnapshotClass`。
|
||
|
||
|
||
```yaml
|
||
apiVersion: snapshot.storage.k8s.io/v1alpha1
|
||
kind: VolumeSnapshotClass
|
||
metadata:
|
||
name: csi-hostpath-snapclass
|
||
snapshotter: csi-hostpath
|
||
parameters:
|
||
```
|
||
|
||
<!--
|
||
### Snapshotter
|
||
|
||
Volume snapshot classes have a snapshotter that determines what CSI volume plugin is
|
||
used for provisioning VolumeSnapshots. This field must be specified.
|
||
-->
|
||
|
||
### 快照生成器（Snapshotter）
|
||
|
||
卷快照类具有一个快照生成器，用于确定配置 VolumeSnapshot 的 CSI 卷插件。 必须指定此字段。
|
||
|
||
<!--
|
||
## Parameters
|
||
|
||
Volume snapshot classes have parameters that describe volume snapshots belonging to
|
||
the volume snapshot class. Different parameters may be accepted depending on the
|
||
`snapshotter`.
|
||
-->
|
||
|
||
## 参数
|
||
|
||
卷快照类具有描述属于卷快照类的卷快照参数。 可根据 `snapshotter` 接受不同的参数。
