Azure DNS – Using PowerShell V1.0 to Add a Subdomain

Azure PowerShell Version 1.0 has great benefits, and also has many breaking changes. Since I wrote about updating a naked domain RecordSet, I received a few questions. This is a post about adding a Subdomain to an existing RecordSet.

Most of breaking changes are minor. If your script leveraged Azure Resource Manager (ARM), start by replacing ‘-Azure‘ with ‘-AzureRm‘. This change was made because the Switch-AzureMode CmdLet was removed.

Using PowerShell to Add a Subdomain

Login-AzureRmAccount -SubscriptionName 'Visual Studio Ultimate with MSDN'

$zone = Get-AzureRmDnsZone -Name 'alexandrebrisebois.com' `
                           -ResourceGroupName 'BriseboisDNS'

$recordSet = New-AzureRmDnsRecordSet -Name 'liveqna' `
                                     -Zone $zone `
                                     -Ttl 60 `
                                     -RecordType CNAME

Add-AzureRmDnsRecordConfig -RecordSet $recordSet `
                           -Cname 'liveqna.eastus.cloudapp.azure.com'

# Don't forget to use the Set-AzureRmDnsRecordSet cmdlet
# to apply the changes

Set-AzureRmDnsRecordSet -RecordSet $recordSet

Resolve-DnsName -Name 'liveqna.alexandrebrisebois.com' 
                -Type ALL 
                -DnsOnly
