Lab Overview

In this lab, we will learn how to use Azure CLI commands from the cloud shell to create a virtual network, create a virtual machine and attach a network security group to the new subnet. We will familiarize with Azure cloud shell and run CLI commands in Bash shell.

Lab Diagram

Start Cloud Shell

1. Launch Cloud Shell from the top navigation of the Azure portal

   

2. Select a subscription to create a storage account and Microsoft Azure Files share

3. Select “Create storage”

4. This should bring you to the cloud shell prompt. You can run Azure CLI commands from here.

Select Bash

Check that the environment drop-down from the left-hand side of shell window says Bash.

We are ready to run CLI commands to create our virtual network.

Create the virtual network

1. Define a group of variables:

   ResourceGroup=rg-lab
   VnetName=vnet-hub
   VnetPrefix=10.0.0.0/16
   SubnetName=vnet-hub-subnet1
   SubnetPrefix=10.0.1.0/24
   Location=westus2
   

2. Run the command to create a virtual network vnet-hub, with one subnet vnet-hub-subnet1.

   az network vnet create -g $ResourceGroup -n $VnetName --address-prefix $VnetPrefix --subnet-name $SubnetName --subnet-prefix $SubnetPrefix -l $Location
   

Create the NSG and security rule

1. Define additional variables:

   Nsg=nsg-hub
   NsgRuleName=vnet-hub-allow-ssh
   DestinationAddressPrefix=10.0.1.0/24
   DestinationPortRange=22
   

2. Create the Network Security Group and add the security rule

   az network nsg create --name $Nsg --resource-group $ResourceGroup --location $Location
   az network nsg rule create -g $ResourceGroup --nsg-name $Nsg --name $NsgRuleName --direction inbound --destination-address-prefix $DestinationAddressPrefix --destination-port-range $DestinationPortRange --access allow --priority 100
   

Attach the NSG to the subnet

1. Attach the network security group to vnet-hub-subnet1

   az network vnet subnet update -g $ResourceGroup -n $SubnetName --vnet-name $VnetName --network-security-group $Nsg
   

Create a VM

1. Declare additional variables

   VmName=vnet-hub-vm1
   AdminUser=azureuser
   AdminPassword=Azure123456!
   

2. Create the virtual machine

   az vm create --resource-group $ResourceGroup --name $VmName --image UbuntuLTS --vnet-name $VnetName --subnet $SubnetName  --admin-username $AdminUser --admin-password $AdminPassword
   az network vnet subnet list -g $ResourceGroup --vnet-name $VnetName -o table
