Azure CLI: Your Quick Start Guide to Managing Azure Resources

Do you want to optimize your management of Azure resources using the Azure Command-Line Interface (CLI)? This guide will walk you through all the essentials, making it user-friendly for both novices and those looking to refresh their knowledge.

What is Azure CLI?

Azure CLI is a versatile command-line tool that streamlines the management of Azure resources. Rather than going through the Azure portal, Azure CLI allows you to access your Azure services directly via the command line, which can save time and enhance your productivity.

Setting Up Azure CLI

System Requirements

Before you begin, ensure you meet the following requirements:

• An operating system like Windows, macOS, or Linux
• Python 3.6 or a later version (for some installations)
• An internet connection to download Azure CLI

Installation Steps

Follow these straightforward steps to install Azure CLI:

1. Open your terminal or command prompt.

2. Run the corresponding command for your OS:

   • Windows: Use the .msi installer

   • macOS:
     bash
     brew update && brew install azure-cli

   • Linux:
     bash
     curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

3. Confirm the installation:
   bash
   az –version

Logging In

After installation, log in to your Azure account:

bash
az login

A browser window will launch, prompting you to sign in. Once logged in, you’ll be able to view your subscriptions.

Basic Azure CLI Commands

Viewing Your Resources

To list the resources in your subscription, use:

bash
az resource list

This command will show all resources linked to your account, such as VMs and storage accounts.

Creating a Resource Group

Resource groups are key for efficient Azure resource management. Here’s how to create one:

bash
az group create –name MyResourceGroup –location eastus

This will establish a new resource group titled "MyResourceGroup" in the East US region.

Deploying Virtual Machines

To create a Virtual Machine (VM), use:

bash
az vm create \
–resource-group MyResourceGroup \
–name MyVM \
–image UbuntuLTS \
–admin-username azureuser \
–generate-ssh-keys

This command sets up a new Ubuntu VM in the specified resource group with automatically generated SSH keys.

Common Challenges and Fixes

Authentication Issues

Login failures are a frequent challenge. If you see "unable to access account," make sure:

• You have the necessary permissions.
• Your Azure account is active.

Resource Not Found

If you encounter a “Resource not found” error, check:

• The resource name is correct.
• The resource group is valid.

Best Practices for Using Azure CLI

• Scripting: Incorporate Azure CLI commands into scripts for automation, enabling efficient management of multiple resources at once.
• Regular Updates: Stay current with Azure CLI updates. Execute az upgrade to access the latest features and fixes.
• Utilize Help Resources: If you hit a snag, leverage the built-in help feature with any command for more details:
  bash
  az –help

Real-World Example: Infrastructure as Code

If you have a project with recurring infrastructure setup needs, scripting your Azure CLI commands can save you time and provide uniformity in deployments. For instance, a script that creates a resource group, VMs, and networking resources can execute in mere minutes.

Conclusion

The Azure CLI is an invaluable tool for effectively managing Azure resources. By getting to know its commands and workflows, you can enhance your cloud operations. Keep practicing, explore CLI help options, and apply best practices to your everyday tasks.
