Deploy Linux VM with Networking using Azure CLI Script

Azure CLI is a command-line tool for managing Azure resources on Windows, macOS, and Linux. Combined with Bash scripting, it lets you automate infrastructure deployments so the same commands run the same way every time. Teams use this pattern to reduce manual errors and to practice Infrastructure as Code without jumping straight to ARM or Bicep.

A Bash script packages those CLI commands into one file: argument checks, resource lookups with JMESPath, and a Linux VM with VNet, subnet, NSG, public IP, and NIC created in a single run.

In this lab, you will write deploy.sh, run it against your lab resource group, and SSH into the Linux VM it creates.

Objectives

By completing this intermediate lab, you will be able to:

• Build a reusable Bash script that deploys Azure resources with Azure CLI
• Validate script arguments and test that a resource group exists before deploying
• Capture Azure CLI output with command substitution and JMESPath queries
• Deploy a Linux VM with VNet, subnet, NSG, public IP, and NIC
• Configure SSH key authentication for the VM

Who is this lab for?

This lab is designed for:

• Cloud Engineers who need to automate Azure deployments with scripting
• DevOps Engineers looking to practice Infrastructure as Code with Azure CLI
• System Administrators transitioning to cloud-based automation

You should already be comfortable with a Bash terminal and with signing in through Azure CLI.
