如何在ARM模板中多次运行同一脚本？
如何在ARM模板中多次运行同一脚本？
提问于 2018-07-02 22:50:31
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azure快速入门模板here。
我希望使用"copy"函数多次运行该脚本，因为我希望在部署VM时安装10个代理。当我尝试部署我的模板时，我得到了这个错误：
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，如何使用copy函数安装10个构建代理，以便拥有vsts-agent-1, vsts-agent-2, etc
下面是该模板的相关代码片段：
{
"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'))]"
}
}
}
]EDIT1
我已经更新了模板并移出子资源，以致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'))]"
}
}
}然而，当我尝试部署时，我得到了这个错误：
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.

我相信你要找的东西就在这里：https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-multiple
其中，您可以使用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示例和干净的方法，但是对于上面的模板，如果您希望命名约定也与NIC等一致，则需要对模板的大部分进行一些更改
像这样的东西应该会帮助你开始行动：
{
"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遍历的计数。在上面的链接中也有如何做到这一点的示例。
希望这能有所帮助！

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 }
