Google Cloud NetApp Volumes后端配置选项和示例

贡献者
PDF

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

ve版本

始终为 1

storageDriverName

存储驱动程序的名称

的值 storageDriverName 必须指定为"gosle-Cloud NetApp-volumes"。

backendName

(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

storagePools

用于指定用于创建卷的存储池的可选参数。

projectNumber

Google Cloud 帐户项目编号。此值可在Google Cloud门户主页上找到。

位置

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 location 可用于在多个Google Cloud区域的节点上计划的工作负载。跨区域流量会产生额外成本。

apiKey

具有角色的Google Cloud服务帐户的API密钥 netappcloudvolumes.admin 。它包括 Google Cloud 服务帐户专用密钥文件的 JSON 格式的内容（逐字复制到后端配置文件）。 apiKey`必须包括以下键的键值对： `type、 project_id、 client_email、、 client_id auth_uri token_uri auth_provider_x509_cert_url`和 `client_x509_cert_url。

nfsMountOptions

精细控制 NFS 挂载选项。

"nfsvers=3"

limitVolumeSize

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）

s服务级别

存储池及其卷的服务级别。值为 flex、、 standard premium`或 `extreme。

网络

用于GCNV卷的Google Cloud网络。

debugTraceFlags

故障排除时要使用的调试标志。例如， {"api":false, "method":true}。除非您正在进行故障排除并需要详细的日志转储，否则请勿使用此功能。

空

supportedTopologies

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：
supportedTopologies:
- topology.kubernetes.io/region: asia-east1
topology.kubernetes.io/zone: asia-east1-a

卷配置选项

您可以在中控制默认卷配置 defaults 部分。

参数 Description Default

exportRule

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

snapshotDir

访问 ` .snapshot` 目录

对于NFSv4、为"TRUE"；对于NFSv3、为"false"

sSnapshot 预留

为快照预留的卷百分比

""(接受默认值0)

unixPermissions

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"。

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。
