針對GCP後端設定CVS

貢獻者
PDF

瞭Cloud Volumes Service 解如何使用所提供的範例組態、將適用於Google Cloud Platform（GCP）的NetApp功能（CVS）設定為Astra Trident安裝的後端。

瞭解Astra Trident對CVS for GCP的支援

Astra Trident支援預設CVS服務類型為on的磁碟區 "GCP"。無論CVS服務類型允許的最小值為何、Astra Trident都不支援低於100 GiB的CVS磁碟區。因此、如果要求的磁碟區小於最小大小、Trident會自動建立100 GiB磁碟區。

您需要的產品

以設定及使用 "適用於 Google Cloud Cloud Volumes Service" 後端、您需要下列項目：

  • 使用NetApp CVS設定的Google Cloud帳戶

  • Google Cloud帳戶的專案編號

  • Google Cloud服務帳戶 netappcloudvolumes.admin 角色

  • CVS服務帳戶的API金鑰檔

後端組態選項

如需後端組態選項、請參閱下表：

參數 說明 預設

version

永遠為1

storageDriverName

儲存驅動程式名稱

「GCP-CVS」

backendName

自訂名稱或儲存後端

驅動程式名稱+「_」+ API金鑰的一部分

storageClass

儲存類型：任您選擇 hardware （效能最佳化）或 software （CVS服務類型）

projectNumber

Google Cloud帳戶專案編號。此值可在Google Cloud入口網站的首頁找到。

apiRegion

CVS帳戶區域。這是後端配置磁碟區的區域。

apiKey

的Google Cloud服務帳戶API金鑰 netappcloudvolumes.admin 角色：其中包含Google Cloud服務帳戶私密金鑰檔案（逐字複製到後端組態檔）的JSON-格式內容。

proxyURL

Proxy URL（如果需要代理伺服器才能連線至CVS帳戶）。Proxy伺服器可以是HTTP Proxy或HTTPS Proxy。對於HTTPS Proxy、會跳過憑證驗證、以允許在Proxy伺服器中使用自我簽署的憑證。不支援已啟用驗證的Proxy伺服器。

nfsMountOptions

精細控制NFS掛載選項。

"nfsves=3"

limitVolumeSize

如果要求的磁碟區大小高於此值、則資源配置失敗

""（預設不強制執行）

serviceLevel

新磁碟區的CVS服務層級。這些值包括「標準」、「高級」和「極端」。

"標準"

network

用於CVS磁碟區的GCP網路

「預設」

debugTraceFlags

疑難排解時要使用的偵錯旗標。範例： \{"api":false, "method":true}。除非您正在進行疑難排解並需要詳細的記錄傾印、否則請勿使用此功能。

null

如果使用共享的VPC網路、兩者都是 projectNumber 和 hostProjectNumber 必須指定。在這種情況下、 projectNumber 是服務專案、以及 hostProjectNumber 是主機專案。

。 apiRegion 代表Astra Trident建立CVS磁碟區的GCP區域。建立跨區域Kubernetes叢集時、會在中建立CVS磁碟區 apiRegion 可用於在多個GCP區域的節點上排程的工作負載。請注意、跨區域流量會產生額外成本。

註

  • 若要啟用跨區域存取、您的StorageClass定義適用於 allowedTopologies 必須包含所有區域。例如：

    - key: topology.kubernetes.io/region
  values:
  - us-east1
  - europe-west1

  • storageClass 是選用參數、可用來選取所需的參數 "CVS服務類型"。您可以從基礎CVS服務類型中進行選擇 (storageClass=software）或CVS效能服務類型 (storageClass=hardware）、這是Trident預設使用的功能。請務必指定 apiRegion 提供各自的CVS storageClass 在後端定義中。
警告 Astra Trident與Google Cloud上的基礎CVS服務類型整合、是一項*測試版功能、不適用於正式作業工作負載。Trident 完全支援 CVS效能服務類型、並依預設使用。

每個後端都會在單一Google Cloud區域中配置磁碟區。若要在其他區域建立磁碟區、您可以定義其他後端。

您可以在組態檔的特殊區段中指定下列選項、以控制預設的每個Volume佈建方式。請參閱下列組態範例。

參數 說明 預設

exportRule

新磁碟區的匯出規則

「0.00.0.0/0」

snapshotDir

存取 .snapshot 目錄

"假"

snapshotReserve

保留給快照的磁碟區百分比

""（接受CVS預設值為0）

size

新磁碟區的大小

「100Gi」

。 exportRule 值必須是以逗號分隔的清單、以CIDR表示法列出所有的IPv4位址或IPv4子網路組合。

註 針對在CVS Google Cloud後端上建立的所有磁碟區、Trident會在儲存資源池上的所有標籤配置時複製到儲存磁碟區。儲存管理員可以定義每個儲存資源池的標籤、並將儲存資源池中建立的所有磁碟區分組。這是根據後端組態中提供的一組可自訂標籤、方便區分磁碟區的方法。

範例1：最低組態

這是絕對最低的後端組態。

下列StorageClass定義係指上述儲存資源池。使用 parameters.selector 欄位中、您可以為每個StorageClass指定用於裝載Volume的虛擬集區。該磁碟區會在所選的資源池中定義各個層面。

第一個StorageClass (cvs-extreme-extra-protection）對應至第一個虛擬儲存資源池。這是唯一提供極致效能、快照保留率為10%的資源池。最後一個StorageClass (cvs-extra-protection）撥出提供快照保留10%的任何儲存資源池。Astra Trident決定選取哪個虛擬儲存池、並確保符合快照保留需求。

接下來呢？

建立後端組態檔之後、請執行下列命令：

tridentctl create backend -f <backend-file>

如果後端建立失敗、表示後端組態有問題。您可以執行下列命令來檢視記錄、以判斷原因：

tridentctl logs

識別並修正組態檔的問題之後、您可以再次執行create命令。
