Creating Network Interface using PowerShell

NIC_01

Hey folks,

Continuing our series of articles on how to create resources in Azure using PowerShell, let’s talk about creating the network interface using PowerShell, creating the network interface and assigning it to a VM and associating it to a VNET is easier via shell command.

Now let’s assign some variables to create the network interface.

$RGName= “RG_GETPRACTICAL”
$NIC1=”Nic-GP-VM-01″
$LOCATION= “UKSouth”
$VNETNAME=”VNet-GETPRACTICAL”
$subnetIndex=0

NIC_02

This “SubnetIndex” variable is very important in the creation process, as it will identify each of your VNETs within your environment. In the case of this article I have a single VNET so I am considering the value “0”, but if you need to pull this value, just run a “Get-AzVirtualNetwork” with the add-ons such as resource group and VNET name.

Now let’s validate if the network exists within the environment.

$VNET=Get-AzVirtualNetwork -Name $VNETName -ResourceGroupName $RGName

NIC_03

Next we will create a public IP for the network interface.

$PIP=New-AzPublicIpAddress -Name $NIC1 -ResourceGroupName $RGName -Location $LOCATION -AllocationMethod Dynamic

NIC_04

Finally, we will create the network interface associating the public IP and the VNET that exists within our environment.

$NIC=New-AzNetworkInterface -Name $NIC1 -ResourceGroupName $RGName -Location $LOCATION -SubnetId $vnet.Subnets[$subnetIndex].Id -PublicIpAddressId $PIP.Id

NIC_05

Your network interface has now been successfully created.

Thanks guys and until the next post!
