What is azure cli

Overview

Azure CLI is Microsoft's command-line interface for managing Azure cloud resources and services. It provides an alternative to the Azure Portal and Azure PowerShell for infrastructure provisioning, configuration, and management. The tool is built on the Azure SDK for Python and is designed to be lightweight, efficient, and easy to use for developers and system administrators working with Azure.

Installation and Setup

Azure CLI can be installed on Windows, macOS, and Linux systems. Installation methods include using package managers like apt, brew, or msi installers, or downloading from the official Microsoft website. Once installed, users authenticate to their Azure subscriptions using the 'az login' command, which opens a browser for interactive authentication. After authentication, users can manage any Azure resources within their subscribed accounts and roles.

Core Functionality

Azure CLI provides commands for managing virtually all Azure services including virtual machines, storage accounts, databases, networking, and web applications. The command structure follows a pattern of 'az [service] [operation] [parameters]'. For example, 'az vm create' creates a virtual machine, while 'az storage account list' displays all storage accounts. The tool includes comprehensive help documentation accessible with the '--help' flag on any command.

Automation and Scripting

Azure CLI is particularly powerful for automation and infrastructure-as-code scenarios. Administrators and developers can create bash or PowerShell scripts that execute multiple Azure CLI commands in sequence, automating complex deployment and management workflows. This capability is essential for continuous integration and continuous deployment (CI/CD) pipelines, where Azure resources need to be provisioned and configured automatically.

Advanced Features

The tool includes interactive mode for exploring available commands and parameters, output formatting options for JSON, table, and YAML formats, and query capabilities for filtering and processing command output. Azure CLI supports extensions that add specialized functionality for specific services. Developers can also create custom scripts that combine Azure CLI commands with other tools and programming languages for sophisticated resource management solutions.
