本文介绍了使用 PowerShell 脚本记录 Azure 私有 DNS 区域的步骤。该脚本可以获取每个区域的名称、订阅名称、资源组名称以及关联的虚拟网络名称，并将其写入 Markdown 表格中，方便用户进行复制粘贴和文档整理。

👨‍💻 该脚本首先获取所有 Azure 订阅，并使用 `Get-AzPrivateDnsZone` 命令获取每个订阅下的所有私有 DNS 区域。

🌐 对于每个区域，脚本使用 `Get-AzPrivateDnsVirtualNetworkLink` 命令获取与该区域关联的虚拟网络链接，并提取虚拟网络名称。

📝 脚本将区域名称、订阅名称、资源组名称和虚拟网络名称写入一个 Markdown 表格中，并将其保存到名为 `dnsLinks.md` 的文件中。

💡 脚本使用 `try...catch` 语句来处理可能的错误，并使用 `break` 语句跳过特定订阅。

🚀 该脚本可以快速方便地记录 Azure 私有 DNS 区域信息，并提供清晰易懂的表格格式，方便用户进行文档整理和维护。

I found myself in a situation where I needed to document a lot of Azure Private DNS Zones. I needed the following information:

Name of the zoneSubscription nameResource group nameName of associated virtual networks

The list was long so a copy and paste from the Azure Portal was going to take too long. Instead, I put a few minutes into a script to do the job – it even writes the content as a Markdown table in a .md file, making it super simple to copy/paste the entire piece of text into my documentation in VS Code.

cls$subs = Get-AzSubscription$outString = "| Zone Name | Subscription Name | Resource Group Name | Linked Virtual Network |"Write-Host $outString$outString | Out-File "dnsLinks.md"$outString = "| --------- | ----------------- | ------------------- | ---------------------- |"Write-Host $outString$outString | Out-File "dnsLinks.md" -Appendforeach ($sub in $subs){    try    {        $context = Set-AzContext -subscription $sub.id           $zones = Get-AzPrivateDnsZone        foreach ($zone in $zones)        {            if ($sub.Name -eq "connectivity" -or $sub.Name -eq "connectivity-canary")    {        break    }            try            {                $links = Get-AzPrivateDnsVirtualNetworkLink -ResourceGroupName $zone.ResourceGroupName -ZoneName $zone.Name                       foreach ($link in $links)                {                    try                    {                        $vnetName = ($link.VirtualNetworkId.Split("/")) | Select-Object -Last 1                        $outString  = "| " + $zone.name + " | " + $context.Subscription.Name + " | " + $zone.ResourceGroupName + " | " + $vnetName + " |"                        Write-Host $outString                        $outString | Out-File "dnsLinks.md" -Append                    }                    catch {}                }             }             catch {}        }      }    catch {}}

It probably wouldn’t take a whole lot more work to add any DNS records if you needed that information too.
