powershell - 如何在Azure ASM中指定DNS名称(域名)前缀？

Question

这是我用来在 Azure 中创建经典 (ASM) VM 的脚本

param(
[switch] $Help = $false,                                                      
$azurePassword,                                                               
$azureUsername ,                                                              
$azureSubscriptionName ,
$VMImageName,                                                                 
$azureStorageAccountName,
$AzureResourceGroupName,
$VMSize,                                                                      
$VMName,
$VMAdministratorUsername,
$VMAdministratorPassword,
$VNetName,
$VNetSubnetName
)

我用参数(等等)来调用它

• AzureResourceGroupName“testBananas”
• 虚拟机名称“testOranges”

它工作正常并创建虚拟机，如屏幕截图所示

如您所见，VMName 是 testOranges，它是在服务(资源组)testBananas 中创建的。

但 DNS 名称默认创建为 testBananas.cloudapp.net我希望它是 testOranges.cloudapp.net 或我指定的任何内容。我认为 DNS 名称是默认填充的。

所以我的问题是:

如何在 Azure ASM 中指定 DNS 名称前缀？

我找到了很多使用自定义 dns 或将其加入域的信息...但我不想这样做，我只想指定我的自定义 DNSname.cloudapp.net 因为我计划在同一资源组中拥有多个虚拟机

注意 1:当我执行脚本时，我收到此警告:

WARNING: No deployment found in service: 'testBananas'

注 2:如果创建第二个虚拟机“test-Apples”，则 DNS 名称和公共(public) IP 与“test-Oranges”相同，但专用 IP 不同。 test-oranges 的外部 SSH 端口是 55525，test-apples 的外部 SSH 端口是 53456。如果我在两者中都使用 SSH 并执行“hostname”，则名称是匹配的...

我的脚本肯定有问题:-(

Answer 1

在您的#7 配置虚拟机中!你有

New-AzureService -ServiceName $AzureResourceGroupName `
                 -Location "North Europe" `
                 -ErrorAction SilentlyContinue `
                 -WarningAction SilentlyContinue

将 $AzureResourceGroupName 更改为 TestOranges 将为您提供所需的结果

您遇到的问题是由于 ASM 不像 ARM 那样使用资源组。 (它对它们的使用有些不一致 - 它很大程度上用名称做自己的事情)
