Google Cloud NetApp Volumes后端配置选项和示例
了解适用于Google Cloud NetApp卷的NFS后端配置选项并查看配置示例。
后端配置选项
每个后端都会在一个 Google Cloud 区域中配置卷。要在其他区域创建卷,您可以定义其他后端。
参数 | Description | Default |
---|---|---|
|
始终为 1 |
|
|
存储驱动程序的名称 |
的值 |
|
(可选)存储后端的自定义名称 |
驱动程序名称 + "_" + API 密钥的一部分 |
|
用于指定用于创建卷的存储池的可选参数。 |
|
|
Google Cloud 帐户项目编号。此值可在Google Cloud门户主页上找到。 |
|
|
Trident创建GCNV卷的Google Cloud位置。创建跨区域Kubnetes集群时、在中创建的卷 |
|
|
具有角色的Google Cloud服务帐户的API密钥 |
|
|
精细控制 NFS 挂载选项。 |
"nfsvers=3" |
|
如果请求的卷大小超过此值、则配置失败。 |
"" (默认情况下不强制实施) |
|
存储池及其卷的服务级别。值为 |
|
|
用于GCNV卷的Google Cloud网络。 |
|
|
故障排除时要使用的调试标志。例如, |
空 |
|
表示此后端支持的区域和区域的列表。有关详细信息,请参阅 "使用 CSI 拓扑"。例如: |
卷配置选项
您可以在中控制默认卷配置 defaults
部分。
参数 | Description | Default |
---|---|---|
|
新卷的导出规则。必须是IPv4地址任意组合的逗号分隔列表。 |
"0.0.0.0/0 |
|
访问 ` .snapshot` 目录 |
对于NFSv4、为"TRUE";对于NFSv3、为"false" |
|
为快照预留的卷百分比 |
""(接受默认值0) |
|
新卷的UNIX权限(4个八进制数字)。 |
"" |
示例配置
以下示例显示了将大多数参数保留为默认值的基本配置。这是定义后端的最简单方法。
最低配置
这是绝对的最低后端配置。使用此配置时、Trident会发现在配置位置委派给Google Cloud NetApp卷的所有存储池、并随机将新卷放置在其中一个池上。由于 nasType
省略了、因此会 nfs
应用默认设置、后端将为NFS卷配置。
当您刚刚开始使用Google Cloud NetApp卷并尝试操作时、此配置是理想的选择、但实际上、您很可能需要为您配置的卷提供额外的范围界定。

虚拟池配置
此后端配置可在一个文件中定义多个虚拟池。虚拟池在一节中进行了定义 storage
。如果您有多个存储池支持不同的服务级别、而您希望在Kubbernetes中创建表示这些服务级别的存储类、则这些选项板非常有用。虚拟池标签用于区分池。例如、在以下示例中 performance
、标签和 serviceLevel
类型用于区分虚拟池。
此外、您还可以设置一些适用于所有虚拟池的默认值、并覆盖各个虚拟池的默认值。在以下示例中、 snapshotReserve
和 exportRule
用作所有虚拟池的默认值。
有关详细信息,请参阅 "虚拟池"。

支持的拓扑配置
Trident可以根据区域和可用性区域为工作负载配置卷。 `supportedTopologies`此后端配置中的块用于提供每个后端的区域和分区列表。此处指定的区域和分区值必须与每个Kubnetes集群节点上标签中的区域和分区值匹配。这些区域和分区表示可在存储类中提供的允许值列表。对于包含后端提供的部分区域和区域的存储类、Trident会在上述区域和区域中创建卷。有关详细信息,请参阅 "使用 CSI 拓扑"。

下一步是什么?
创建后端配置文件后,运行以下命令:
kubectl create -f <backend-file>
要验证是否已成功创建后端、请运行以下命令:
kubectl get tridentbackendconfig NAME BACKEND NAME BACKEND UUID PHASE STATUS backend-tbc-gcnv backend-tbc-gcnv b2fd1ff9-b234-477e-88fd-713913294f65 Bound Success
如果后端创建失败,则后端配置出现问题。您可以使用命令说明后端 kubectl get tridentbackendconfig <backend-name>
、或者运行以下命令查看日志以确定原因:
tridentctl logs
确定并更正配置文件的问题后、您可以删除后端并再次运行create命令。
