Creating a new NSG rule with PowerShell

Alternatively, we can create an NSG rule using PowerShell. This command can be executed right after the NSG has been created, allowing us to create and configure an NSG in a single script. This way, we can standardize deployment and have rules applied each time an NSG is created.

Getting ready

Open the PowerShell console and make sure you are connected to your Azure subscription.

How to do it...

To create a new NSG rule, execute the following command:

$nsg = Get-AzNetworkSecurityGroup -Name 'nsg1' -ResourceGroupName 'Packt-Networking-Script'
$nsg | Add-AzNetworkSecurityRuleConfig -Name 'Allow_HTTPS' -Description 'Allow_HTTPS' -Access Allow -Protocol Tcp -Direction Inbound -Priority 100 -SourceAddressPrefix Internet -SourcePortRange * -DestinationAddressPrefix * -DestinationPortRange 443 | Set-AzNetworkSecurityGroup

How it works...

Using a script, creating an NSG rule is just a matter...
