使用 Resource Manager 範本部署 Azure Spot Virtual Machines

適用於:✔️ Linux VM

使用 Azure Spot Virtual Machines 可讓您以大幅降低的成本使用我們未運用的容量。 在任何時候,只要 Azure 又需要這些容量,Azure 基礎結構就會收回 Azure 現成 VM。 Azure 現成 VM 對於可因應中斷的工作負載來說很好用,例如批次處理作業、開發/測試環境、大量運算工作負載等。

Azure Spot Virtual Machines 的定價是根據區域和 SKU 的變數為準。 如需詳細資訊,請參閱 LinuxWindows 的 VM 定價。

您可以選擇為 VM 設定您願意支付的每小時價格上限。 Azure 現成 VM 的最高價格可以設為美元 (USD),且最多可取小數點後五位。 例如,0.98765 的值是每小時 $0.98765 美元的最大價格。 如果您將最高價格設定為 -1,則 VM 收回不是以價格為基礎,而且價格會是 Azure Spot VM 的目前價格,或標準 VM 的價格,只要有可用的容量和配額即可。 如需設定價格上限的詳細資訊,請參閱 Azure 現成 VM - 定價

使用範本

針對 Azure Spot VM 樣本部署,請使用"apiVersion": "2019-03-01" 或更新版本。 新增 priorityevictionPolicybillingProfile 屬性至您的範本:

"priority": "Spot",
"evictionPolicy": "Deallocate",
"billingProfile": {
    "maxPrice": -1
}

以下是範例範本,其中包含 Azure Spot VM 的已新增屬性。 以您自己的名稱取代資源名稱,並以 VM 上本機管理員帳戶的密碼取代 <password>

模擬收回

您可以模擬 Azure 現成 VM 的收回,以測試應用程式對突然收回的回應。

將下列參數取代為您的資訊:

  • subscriptionId
  • resourceGroupName
  • vmName
