将 Azure 磁盘加密与虚拟机规模集扩展排序配合使用

适用于:✔️ Linux VM ✔️ Windows VM ✔️ 统一规模集

Azure 磁盘加密等扩展可以按指定顺序添加到 Azure 虚拟机规模集。 为此,请使用扩展排序

通常,应将加密应用到磁盘:

  • 在准备磁盘或卷的扩展或自定义脚本之后。
  • 在访问或使用加密磁盘或卷上的数据的扩展或自定义脚本之前。

在上述任一情况下,provisionAfterExtensions 属性都指定在序列中稍后应添加哪个扩展。

示例 Azure 模板

如果希望在另一个扩展之后应用 Azure 磁盘加密,请将 provisionAfterExtensions 属性放在 AzureDiskEncryption 扩展块中。

下面是一个使用“CustomScriptExtension”的例子,这是一个初始化和格式化 Windows 磁盘的 PowerShell 脚本,后跟“AzureDiskEncryption”:

"virtualMachineProfile": {
  "extensionProfile": {
    "extensions": [
      {
        "type": "Microsoft.Compute/virtualMachineScaleSets/extensions",
        "name": "CustomScriptExtension",
        "location": "[resourceGroup().location]",
        "properties": {
          "publisher": "Microsoft.Compute",
          "type": "CustomScriptExtension",
          "typeHandlerVersion": "1.9",
          "autoUpgradeMinorVersion": true,
          "forceUpdateTag": "[parameters('forceUpdateTag')]",
          "settings": {
            "fileUris": [
              "https://raw.githubusercontent.com/Azure-Samples/compute-automation-configurations/master/ade-vmss/FormatMBRDisk.ps1"
            ]
          },
          "protectedSettings": {
           "commandToExecute": "powershell -ExecutionPolicy Unrestricted -File FormatMBRDisk.ps1"
          }
        }
      },
      {
        "type": "Microsoft.Compute/virtualMachineScaleSets/extensions",
        "name": "AzureDiskEncryption",
        "location": "[resourceGroup().location]",
        "properties": {
          "provisionAfterExtensions": [
            "CustomScriptExtension"
          ],
          "publisher": "Microsoft.Azure.Security",
          "type": "AzureDiskEncryption",
          "typeHandlerVersion": "2.2",
          "autoUpgradeMinorVersion": true,
          "forceUpdateTag": "[parameters('forceUpdateTag')]",
          "settings": {
            "EncryptionOperation": "EnableEncryption",
            "KeyVaultURL": "[reference(variables('keyVaultResourceId'),'2018-02-14-preview').vaultUri]",
            "KeyVaultResourceId": "[variables('keyVaultResourceID')]",
            "KeyEncryptionKeyURL": "[parameters('keyEncryptionKeyURL')]",
            "KekVaultResourceId": "[variables('keyVaultResourceID')]",
            "KeyEncryptionAlgorithm": "[parameters('keyEncryptionAlgorithm')]",
            "VolumeType": "[parameters('volumeType')]",
            "SequenceVersion": "[parameters('sequenceVersion')]"
          }
        }
      },
    ]
  }
}

如果希望在另一个扩展之前应用 Azure 磁盘加密,请将 provisionAfterExtensions 属性放在后面跟着的扩展块中。

下面是一个使用“AzureDiskEncryption”(后跟“VMDiagnosticsSettings”,这是一个在基于 Windows 的 Azure VM 上提供监视和诊断功能的扩展)的例子:

"virtualMachineProfile": {
  "extensionProfile": {
    "extensions": [
      {
        "name": "AzureDiskEncryption",
        "type": "Microsoft.Compute/virtualMachineScaleSets/extensions",
        "location": "[resourceGroup().location]",
        "properties": {
          "publisher": "Microsoft.Azure.Security",
          "type": "AzureDiskEncryption",
          "typeHandlerVersion": "2.2",
          "autoUpgradeMinorVersion": true,
          "forceUpdateTag": "[parameters('forceUpdateTag')]",
          "settings": {
            "EncryptionOperation": "EnableEncryption",
            "KeyVaultURL": "[reference(variables('keyVaultResourceId'),'2018-02-14-preview').vaultUri]",
            "KeyVaultResourceId": "[variables('keyVaultResourceID')]",
            "KeyEncryptionKeyURL": "[parameters('keyEncryptionKeyURL')]",
            "KekVaultResourceId": "[variables('keyVaultResourceID')]",
            "KeyEncryptionAlgorithm": "[parameters('keyEncryptionAlgorithm')]",
            "VolumeType": "[parameters('volumeType')]",
            "SequenceVersion": "[parameters('sequenceVersion')]"
          }
        }
      },
      { 
        "name": "Microsoft.Insights.VMDiagnosticsSettings", 
        "type": "extensions", 
        "location": "[resourceGroup().location]", 
        "apiVersion": "2016-03-30", 
        "dependsOn": [ 
          "[concat('Microsoft.Compute/virtualMachines/myVM', copyindex())]" 
        ], 
        "properties": { 
          "provisionAfterExtensions": [
            "AzureDiskEncryption"
          ],
        "publisher": "Microsoft.Azure.Diagnostics", 
          "type": "IaaSDiagnostics", 
          "typeHandlerVersion": "1.5", 
          "autoUpgradeMinorVersion": true, 
          "settings": { 
            "xmlCfg": "[base64(concat(variables('wadcfgxstart'), 
            variables('wadmetricsresourceid'), 
            concat('myVM', copyindex()),
            variables('wadcfgxend')))]", 
            "storageAccount": "[variables('storageName')]" 
          }, 
          "protectedSettings": { 
            "storageAccountName": "[variables('storageName')]", 
            "storageAccountKey": "[listkeys(variables('accountid'), 
              '2015-06-15').key1]", 
            "storageAccountEndPoint": "https://core.chinacloudapi.cn" 
          } 
        } 
      },
    ]
  }
}
