Preparing the Virtual Network and AKS Subnet

Now you can prepare a virtual network with custom ranges and subnet for AKS. If you already have an existing virtual network with a subnet for AKS, you can skip this procedure.

All the created resources must be placed in the same virtual network to prevent performance issues caused by network latency; these resources include resource group, AKS cluster, jump host, and Azure NetApp Files (NFS).

To create the virtual network:

1. Run the following command:

   az network vnet create \
   -g <RESOURCE_GROUP> \
   -n <VNET_NAME> \
   --address-prefix <VNET_CIDR> \
   --subnet-name <SUBNET_NAME> \
   --subnet-prefix <SUBNET_CIDR>

Where:

<RESOURCE_GROUP>: the name of the resource group created in step 1.1

<VNET_NAME>: The assigned name of this virtual network.

<VNET_CIDR>: The CIDR notation for this virtual network. For example, 10.1.0.0/16.

<SUBNET_NAME>: Name for this subnet for AKS.

<SUBNET_CIDR>: The CIDR notation for this subnet. For example, 10.1.1.0/24.

For example, this would create a virtual network demo-vnet, in resource group srg-demo, with range 10.1.0.0/16 and subnet aks-subnet with subnet range 10.1.1.0/24 :

az network vnet create \
-g srg-demo \
-n demo-vnet \
--address-prefix 10.1.0.0/16 \
--subnet-name aks-subnet \
--subnet-prefix 10.1.1.0/24
