Azure PowerShell - VM 标记报告

Question

我有兴趣查询 Azure 订阅以提供标记报告，其中指示 VM 名称、Azure 区域以及每个 VM 的标签和标签值。

我当前的脚本为我提供了除每个标签的标签值之外的所有数据。我的输出显示的结果就好像标签不存在一样。

有人对我的剧本有什么建议吗？谢谢!

param([Parameter(Mandatory = $true)][String] $subscriptionName )

Select-AzSubscription -Subscription $subscriptionName

$allTags = Get-AzTag

$allVMs = Get-AzVM

$vmInformation = @() foreach ($vm in $allVMs) {

$vmInformationObject = New-Object PSObject

$vmName = $vm.Name
$vmRegion = $vm.Location
$vmInformationObject | Add-Member -MemberType NoteProperty -Name "VM_Name" -Value $vmName
$vmInformationObject | Add-Member -MemberType NoteProperty -Name "VM_Region" -Value $vmRegion

$vm_tags = $vm.tags
foreach ($tag in $allTags) {
    $IfTagExists = $false
    foreach ($vmtag in $vm_tags) {
        if ($tag.name -like $vmtag.keys) {
            $IfTagExists = $true
            $vmInformationObject | Add-Member -MemberType NoteProperty -Name $tag.Name -Value $vmtag.$($tag.Name)
            break
        }
    }
    if ($IfTagExists -eq $false) {
        $vmInformationObject | Add-Member -MemberType NoteProperty -Name $tag.Name -Value "--"
    }
}
$vmInformation += $vmInformationObject }

$vmInformation | Export-Csv "path.csv" -NoTypeInformation -Force

这里的问题是比较语句$tag.name -like $vmtag.keys。由于左侧值是标量，右侧值是集合或列表，因此您需要使用包含 comparison operator 。最简单的选项是 -in 或 -contains。

# Option 1
# Use -in when singular item is on the LHS and collection is on RHS
if ($tag.name -in $vmtag.keys) {
            $IfTagExists = $true
            $vmInformationObject | Add-Member -MemberType NoteProperty -Name $tag.Name -Value $vmtag.$($tag.Name)
            break
}

# Option 2
# Use -contains when singular item is on the RHS and collection is on LHS
if ($vmtag.keys -contains $tag.name) {
            $IfTagExists = $true
            $vmInformationObject | Add-Member -MemberType NoteProperty -Name $tag.Name -Value $vmtag.$($tag.Name)
            break
}
