Google Cloud NetApp Volumes 後端組態選項和範例

貢獻者
PDF

瞭解 Google Cloud NetApp Volumes 的 NFS 後端組態選項、並檢閱組態範例。

後端組態選項

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。

參數 說明 預設

version

永遠為1

storageDriverName

儲存驅動程式名稱

的值 storageDriverName 必須指定為「 googoogle 雲端 -NetApp-Volumes 」。

backendName

（選用）儲存後端的自訂名稱

驅動程式名稱+「_」+ API金鑰的一部分

storagePools

選用參數、用於指定用於建立磁碟區的儲存資源池。

projectNumber

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

location

Astra Trident 建立 GCNV Volume 的 Google Cloud 位置。建立跨區域 Kubernetes 叢集時、在中建立的磁碟區 location 可用於跨多個 Google Cloud 區域的節點上排程的工作負載。跨區域流量會產生額外成本。

apiKey

具有此角色的 Google Cloud 服務帳戶的 API 金鑰 netappcloudvolumes.admin 。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。 apiKey`必須包含下列金鑰的金鑰值配對： `type project_id、、 client_email、 client_id、 auth_uri token_uri auth_provider_x509_cert_url、和 client_x509_cert_url。

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

儲存池及其磁碟區的服務層級。這些值包括 flex、 standard、 premium`或 `extreme。

network

用於 GCNV Volume 的 Google Cloud 網路。

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

supportedTopologies

代表此後端所支援的區域和區域清單。如需詳細資訊、請 "使用「csi拓撲」"參閱。例如：
supportedTopologies:
- topology.kubernetes.io/region: europe-west6
topology.kubernetes.io/zone: europe-west6-b

Volume資源配置選項

您可以在組態檔案的區段中控制預設的 Volume 資源配置 defaults。

參數 說明 預設

exportRule

新磁碟區的匯出規則。必須是以逗號分隔的任何 IPv4 位址組合清單。

「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

" （接受預設值 0 ）

unixPermissions

新磁碟區的UNIX權限（4個八進位數字）。

"

組態範例

下列範例顯示基本組態、讓大部分參數保留預設值。這是定義後端最簡單的方法。

最小組態

這是絕對最低的後端組態。有了這項組態、 Astra Trident 會探索您在設定位置中委派給 Google Cloud NetApp Volumes 的所有儲存資源池、並隨機將新磁碟區放在其中一個資源池上。由於省略、因此 nasType nfs 會套用預設值、而後端會為 NFS 磁碟區進行資源配置。

當您剛開始使用 Google Cloud NetApp Volumes 並試用時、這項組態非常理想、但實際上您很可能需要為您所配置的 Volume 提供額外的範圍。

虛擬集區組態

此後端組態會在單一檔案中定義多個虛擬集區。虛擬集區是在一節中定義 storage 。當您有多個儲存集區支援不同的服務層級、而且您想要在 Kubernetes 中建立代表這些層級的儲存類別時、這些功能就很有用。虛擬集區標籤用於區分集區。例如、在下面的範例中、 performance 標籤和 serviceLevel 類型是用來區分虛擬集區。

您也可以將某些預設值設定為適用於所有虛擬集區、並覆寫個別虛擬集區的預設值。在下列範例中 snapshotReserve 、並 exportRule 做為所有虛擬集區的預設值。

如需詳細資訊、請 "虛擬資源池"參閱。

接下來呢？

建立後端組態檔之後、請執行下列命令：

kubectl create -f <backend-file>

若要確認後端已成功建立、請執行下列命令：

kubectl get tridentbackendconfig

NAME               BACKEND NAME       BACKEND UUID                           PHASE   STATUS

如果後端建立失敗、表示後端組態有問題。您可以使用命令來描述後端 kubectl get tridentbackendconfig <backend-name> 、或是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、您可以刪除後端、然後再次執行 create 命令。
