我有一个用于在 ARM 模板中安装 VSTS 构建代理的 powershell 脚本。此模板基于此处的 azure 快速入门模板。

我想使用该"copy"函数多次运行脚本，因为我想在部署 VM 时安装 10 个代理。当我尝试部署我的模板时，我收到此错误：

Error: Code=InvalidTemplate; Message=Deployment template validation failed: 
'The template resource 'CustomScript' at line '247' column '13' is not valid. Copying nested resources is not supported.

我的问题是，我怎样才能安装 10 个具有该copy功能的构建代理，以便我拥有vsts-agent-1, vsts-agent-2, etc？

这是模板的相关片段：

{
      "name": "[parameters('vmName')]",
      "type": "Microsoft.Compute/virtualMachines",
      "location": "[parameters('location')]",
      "apiVersion": "2017-03-30",
      "dependsOn": [
        "[concat('Microsoft.Storage/storageAccounts/', variables('storageAccountName'))]",
        "[concat('Microsoft.Network/networkInterfaces/', variables('vmNicName'))]"
      ],
      "tags": {
        "displayName": "VM01"
      },
      "properties": {
        "hardwareProfile": {
          "vmSize": "[parameters('vmSize')]"
        },
        "osProfile": {
          "computerName": "[parameters('vmName')]",
          "adminUsername": "[parameters('vmAdminUserName')]",
          "adminPassword": "[parameters('vmAdminPassword')]"
        },
        "storageProfile": {
          "imageReference": {
            "publisher": "[variables('vmImagePublisher')]",
            "offer": "[variables('vmImageOffer')]",
            "sku": "[parameters('vmVisualStudioVersion')]",
            "version": "latest"
          },
          "osDisk": {
            "name": "[concat(parameters('vmName'),'_OSDisk')]",
            "caching": "ReadWrite",
            "createOption": "FromImage"
          }
        },
        "networkProfile": {
          "networkInterfaces": [
            {
              "id": "[resourceId('Microsoft.Network/networkInterfaces', variables('vmNicName'))]"
            }
          ]
        }
      },
      "resources": [
        {
          "name": "CustomScript",
          "type": "extensions",
          "location": "[parameters('location')]",
          "apiVersion": "2015-05-01-preview",
          "dependsOn": [
            "[concat('Microsoft.Compute/virtualMachines/', parameters('vmName'))]"
          ],
          "properties": {
            "publisher": "Microsoft.Compute",
            "type": "CustomScriptExtension",
            "typeHandlerVersion": "1.4",
            "settings": {
              "fileUris": [
                "[concat(parameters('_artifactsLocation'),'/InstallVSTSAgent.ps1')]"
              ],
              "commandToExecute": "[concat('powershell.exe -ExecutionPolicy Unrestricted -Command .\\InstallVSTSAgent.ps1 -vstsAccount ', parameters('vstsAccount'), ' -personalAccessToken ', parameters('personalAccessToken'), ' -AgentName ', parameters('vstsAccount'), ' -PoolName ', parameters('poolName'), ' -runAsAutoLogon ', parameters('enableAutologon'), ' -vmAdminUserName ', parameters('vmAdminUserName'), ' -vmAdminPassword ', parameters('vmAdminPassword'))]"
            }
          }
        }
      ]

我已更新模板并将子资源移出，以便子资源与父资源处于同一级别。此部分现在如下所示：

{
  "name": "CustomScript",
  "type": "Microsoft.Compute/virtualMachines/extensions",
  "location": "[parameters('location')]",
  "apiVersion": "2015-05-01-preview",
  "dependsOn": [
    "[concat('Microsoft.Compute/virtualMachines/', parameters('vmName'))]"
  ],
  "copy": {
    "name": "customScriptGroup",
    "count": "[parameters('agentCount')]"
  },
  "properties": {
    "publisher": "Microsoft.Compute",
    "type": "CustomScriptExtension",
    "typeHandlerVersion": "1.4",
    "protectedSettings": {
      "fileUris": [
        "[concat(parameters('_artifactsLocation'),'/InstallVSTSAgent.ps1')]"
      ],
      "commandToExecute": "[concat('powershell.exe -ExecutionPolicy Unrestricted -Command .\\InstallVSTSAgent.ps1 -vstsAccount ', parameters('vstsAccount'), ' -personalAccessToken ', parameters('personalAccessToken'), ' -AgentName ', parameters('vstsAccount')[copyIndex(1)], ' -PoolName ', parameters('poolName'), ' -runAsAutoLogon ', parameters('enableAutologon'), ' -vmAdminUserName ', parameters('vmAdminUserName'), ' -vmAdminPassword ', parameters('vmAdminPassword'))]"
    }
  }
}

但是，当我尝试部署时，出现此错误：

Error: Code=InvalidTemplate; Message=Deployment template validation failed: The template resource 'CustomScript' for type 'Microsoft.Compute/virtualMachines/extensions' at line '247' and column '9' has incorrect segment lengths. A nested resource type must have identical number of segments as its resource name. A root resource type must have segment length one greater than its resource name.

我相信您正在寻找的内容位于此处： https ://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-multiple

您可以使用该copyIndex()函数在循环中迭代以创建多个资源。

上面的链接有很好的例子和一种干净的方法，但是对于上面的模板，如果您希望命名约定也与您的 NIC 等保持一致，则需要对模板的大部分进行一些更改

这样的事情应该可以帮助你开始： 

{
   "name" : "[concat(parameters('vmName'), copyIndex())]",
   "copy": {
      "name" : "vmCopy",
      "count": 10
   }
   ...
   ...
   ...
   "osProfile" : "[concat(parameters('vmName'), copyIndex())]"
   ...
   ...
}

此处的"copy"属性设置复制循环的名称和它将迭代的计数。上面的链接中也有一些例子说明了如何做到这一点。

希望这可以帮助！

干杯，拉奇

我已经能够使用此脚本在服务器上安装多个代理：

Get-ExecutionPolicy

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope CurrentUser

for($i=0; $i -le 9;  $i++)
{
    $suffix=$i.ToString('00')
    $folder="vsts-agent-win-x64-2.144.2-$suffix"
    $agent="myagent-$suffix"

    "$PSScriptRoot\$folder"
    #note: folder needs to be copied for each instance
    #'vsts-agent-win-x64-2.144.2' is the folder after downloading and unzipping agent -manually.
    Copy-Item "$PSScriptRoot\vsts-agent-win-x64-2.144.2" "$PSScriptRoot\$folder" -Recurse

    cd $PSScriptRoot\$folder
 #.\config.cmd --unattended --url https://myaccount.visualstudio.com --auth pat --token myToken --pool 
#default --agent myAgent --runAsAutoLogon --windowsLogonAccount myDomain\myUserName 
#--windowsLogonPassword myPassword
    Write-Host "vsts-agent-win-x64-2.144.2-$suffix"

     .\config.cmd    --unattended `
                    --url "https://devops.my.org/org/" ` #(url of tfs)
                    --auth "pat" `
                    --token "u7s2mbna5v7heqzyfmz5ufrnvlektessebs7flfaf2ll4efzuj7q" `  (tfs token)
                    --pool "foiaModernization" `
                    --agent $agent `
                    --replace `
                    --acceptTeeEula `
                    --runAsService `
                    --windowsLogonAccount "xxx\yyy" `  #not sure if these lines are needed
                    --windowsLogonPassword "JJJJJlllll!!11" #not sure if these lines are

}
