Installing Azure CLI

2.1 Installing Azure CLI

Azure CLI can be installed on Windows, macOS, or Linux.

OS	Installation Command
Windows	Use the MSI Installer
macOS	brew install azure-cli (Homebrew)
Linux (Ubuntu/Debian)	Use apt-get
Linux (RHEL/Fedora)	Use yum/dnf

---

🪟 Installing on Windows

1. Go to the official download page.

2. Download the MSI Installer.

3. Run the installer (Next → Next → Finish).

4. Open Command Prompt or PowerShell and test:

bashCopyEditaz version

✅ You should see the installed version.

---

🍎 Installing on macOS

If you use Homebrew:

bashCopyEditbrew update && brew install azure-cli

Then verify:

bashCopyEditaz version

---

🐧 Installing on Linux (Ubuntu/Debian)

bashCopyEditcurl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

Then verify:

bashCopyEditaz version

---

🔄 2.2 Updating Azure CLI

Azure CLI updates frequently to support new Azure services.

Update using:

OS	Command
Windows	Rerun the MSI installer
macOS	brew upgrade azure-cli
Linux	sudo apt-get update && sudo apt-get install azure-cli

Always try to keep your CLI updated to avoid bugs or missing features!

Check your version:

bashCopyEditaz version

You can view available updates using:

bashCopyEditaz upgrade

---

🔐 2.3 Logging in to Azure

After installation, you must authenticate.

Default login (interactive)

bashCopyEditaz login

✅ This opens a browser window asking for your Microsoft credentials.

---

Login with Device Code (for MFA or Cloud Shell)

If you can’t open a browser (example: SSH session):

az login --use-device-code

This gives you a code to enter at https://microsoft.com/devicelogin.

---

Service Principal Login (for Automation)

For automated scripts, you should log in with a Service Principal:

bashCopyEditaz login --service-principal -u APP_ID -p PASSWORD --tenant TENANT_ID

(We'll dive into Service Principals later in the course.)

---

📂 2.4 Setting the Active Subscription

If you have multiple Azure subscriptions, you need to set the active one.

First, list your subscriptions:

az account list --output table

Example output:

Name	SubscriptionId	State
MyCompany-Production	1234abcd-5678-efgh-9101-ijklmnopqrst	Enabled
MyCompany-Dev	8765zyxw-4321-vuts-1098-ponmlkjihgfed	Enabled

---

Then set your active subscription:

az account set --subscription "MyCompany-Dev"

✅ Now, every command you run will operate against that subscription.

---

🛠️ 2.5 Verifying Your CLI Environment

Double-check everything by running:

az account show

You should see:

• Your current subscription

• Your tenant ID

• Your user ID

And finally:

az group list

If you get a valid response (even if empty), your CLI is ready!
