Azure Public IP scheduled change

Question

I've got an Azure Load Balancer with:

• Load Balancer fronend IP config: Azure Public IP (dynamic)

• Load Balancer backend pool: single VM

Is there a way to schedule periodically change of Azure Public IP? Maybe using automation scripts? Or maybe I can create multiple Azure Public IPs and make LB to switch them periodically?

Answer 1

Yes, it is possible. You could use the following example.

$rgName = "shuilinux"
$nicName = "shui648"
$pipName = "shui-ip"
##unattach public IP on nic
$nic = Get-AzureRmNetworkInterface -ResourceGroupName $rgName -Name $nicName
$nic.IpConfigurations.PublicIpAddress.Id=""
$nic|Set-AzureRmNetworkInterface

##attach public IP to a nic
##If you want to create a new Public IP, use $pip = New-AzureRmPublicIpAddress -Name $pipName -ResourceGroupName $rgName -Location $locName -AllocationMethod Dynamic -Force
$pip = Get-AzureRmPublicIpAddress -Name $pipName -ResourceGroupName $rgName
$nic = Get-AzureRmNetworkInterface -ResourceGroupName $rgName -Name $nicName
$nic.IpConfigurations[0].PublicIpAddress = $pip 
Set-AzureRmNetworkInterface -NetworkInterface $nic
