Azure Powershell 从 CSV 文件中标记 VM

Question

我对 Powershell 脚本很陌生。我正在尝试从 CSV 文件为 azure vm 生成标签。

在 CSV 中，我有以下列标题：

• 虚拟机名称
• 应用
• 子猫
• 环境
• AppOwner
• 位置

我有一个测试 CSV，其中包含以下数据： MattTestVM、TestApp、TestSubapp、Dev、Matt、英国南部

我不确定我在代码中添加了什么错误以使其添加标签。

代码

#Set Credentials

$cred = Get-credential

# Sign-in with Azure account credentials

add-azurermaccount -credential $cred

# Select Azure Subscription

$subscriptionId = (Get-AzureRmSubscription | Out-GridView -Title "Select an Azure Subscription ..." -PassThru).SubscriptionId

#Select specified subscription ID

Select-AzureRmSubscription -SubscriptionId $subscriptionId



$InputCSVFilePath = "C:\test\Tagging1.csv"

#Start loop

foreach ($eachRecord in $InputCSVFilePath)

{

    $VMName = $eachrecord.VMName

    $Application = $eachrecord.Application

    $SubCat = $eachrecord.SubCat

    $Environment = $eachrecord.Environment

    $AppOwner = $eachrecord.AppOwner

    $Location = $eachrecord.Location



     $r = Get-AzureRmResource -ResourceId $ResourceId -ErrorAction Continue



    if($r -ne $null)

    {

        if($r.tags)

        {

            # Tag - Application

            if($r.Tags.ContainsKey("Application"))

            {

                $r.Tags["Application"] = $Application

            }

            else

            {

                $r.Tags.Add("Application", $Application)

            }



            # Tag - SubCat

            if($r.Tags.ContainsKey("subCat"))

            {

                $r.Tags["subCat"] = $subCat

            }

            else

            {

                $r.Tags.Add("subCat", $subCat)

            }



            # Tag - Environment

            if($r.Tags.ContainsKey("Environment"))

            {

                $r.Tags["Environment"] = $Environment

            }

            else

            {

                $r.Tags.Add("Environment", $Environment)

            }



            # Tag - AppOwner

            if($r.Tags.ContainsKey("AppOwner"))

            {

                $r.Tags["AppOwner"] = $AppOwner

            }

            else

            {

                $r.Tags.Add("AppOwner", $AppOwner)

            }



            # Tag - Location

            if($r.Tags.ContainsKey("Location"))

            {

                $r.Tags["Location"] = $Location

            }

            else

            {

                $r.Tags.Add("Location", $Location)

            }



            #Setting the tags on the resource

            Set-AzureRmResource -Tag $r.Tags -ResourceId $r.ResourceId -Force

        }

        else

        {

            #Setting the tags on a resource which doesn't have tags

            Set-AzureRmResource -Tag @{ Application=$Application; subCat=$subCat; Environment=$Environment; AppOwner=$AppOwner; Location=$Location } -ResourceId $r.ResourceId -Force

        }

    }

    else

    {

        Write-Host "Resource Not Found with Resource Id: " + $ResourceId

    }





}

好的，第一件事是：如果没有 ResourceGroupName，您将无法执行此操作，在您的情况下添加它的最佳方法是作为 csv 中的列。

其次，每个人都从某个地方开始，所以永远不要道歉。 :) 我评论了我在下面的代码中修复的大部分问题。您最大的问题是 a) 您实际上并没有从 CSV 加载数据（您只创建了一个包含文件路径的变量），b) 您尝试使用 $ResourceID 而不填充它。

我清理了一下，它现在可以工作了，如果找不到 VM，它会抛出错误。这是我的 test.csv 的内容，其中有一个好的虚拟机和一个不存在的虚拟机。

VMName,ResourceGroup,Application,SubCat,Environment,AppOwner,Location
test-rm-01,test-rg,Thing,Subs,Dev,Nick,Europe
clambake,mygroup,,,,,

这是重新编写的脚本。

# Set Credentials (Fixed this up)

$context = Get-AzureRmContext
if ($context.Account -eq $null) {
    Login-AzureRmAccount
}

# Select Azure Subscription

$subscriptionId = (Get-AzureRmSubscription | Out-GridView -Title "Select an Azure Subscription ..." -PassThru).SubscriptionId

#Select specified subscription ID

Select-AzureRmSubscription -SubscriptionId $subscriptionId

$InputCSVFilePath = "C:\Users\Nick\Desktop\test.csv"
