Azure-Tags标记

实现标记自动化

所有资源继承资源组的tag

1.利用Azure policy中的“Append tag and its default value”， 指定tag Name为application, tag value 为undefined

至此之后你所有建立的azure resource 都会在创建之初就带有这个预设的tag

2.建立资源组时做好tagging

3. 利用azure automation的runbook去遍历所有带有预设tag的resource, 并将对应的resource group的标签应用在其自身。

$connectionName = "AzureRunAsConnection" 
try
{

    $servicePrincipalConnection=Get-AutomationConnection -Name $connectionName

    "Logging in to Azure..."
    Add-AzureRmAccount `
        -ServicePrincipal `
        -TenantId $servicePrincipalConnection.TenantId `
        -ApplicationId $servicePrincipalConnection.ApplicationId `
        -CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint `
        -EnvironmentName AzureChinaCloud
 }
catch {
    if (!$servicePrincipalConnection)
    {
        $ErrorMessage = "Connection $connectionName not found."
        throw $ErrorMessage
    } else{
        Write-Error -Message $_.Exception
        throw $_.Exception
    }
}

Select-AzureRmSubscription -Subscription SubscriptionName
$Resources = (Get-azurermresource -Tag @{ Application="undefined"})

Foreach ($resource in $Resources)
{
    $Rgname = $resource.Resourcegroupname

    $resourceid = $resource.resourceId
    $RGTags = (Get-AzureRmResourceGroup -Name $Rgname).Tags

    $resourcetags = $resource.Tags

            $RGTagFinal = @{}
            $RGTagFinal = $RGTags                  
                    Foreach ($resourcetag in $resourcetags.GetEnumerator())
                    {
                
                    If ($RGTags.Keys -inotcontains $resourcetag.Key)
                        {                        
                                Write-Output "------------------------------------------------"
                                Write-Output "Keydoesn't exist in RG Tags adding to Hash Table" $resourcetag
                                Write-Output "------------------------------------------------"
                                $RGTagFinal.Add($resourcetag.Key,$resourcetag.Value)
                        }    

                    }
            Write-Output "---------------------------------------------"
            Write-Output "Applying the following Tags to $($resourceid)" $RGTagFinal
            Write-Output "---------------------------------------------"
            $Settag = Set-AzureRmResource -ResourceId $resourceid -Tag $RGTagFinal -Force
