Azure CLI

Azure CLI, or Azure Command Line Interface, is a set of commands used to create and manage Azure resources. It is a cross-platform command-line tool that's available for Windows, macOS, and Linux and can be run in the Azure Cloud Shell directly from a web browser.

Azure CLI is designed to be easy to learn and get started with but powerful enough to manage your entire Azure environment. It's optimized for automation and can be used in a DevOps pipeline. You can use Azure CLI to create and manage resources such as virtual machines, storage accounts, and web apps, among others.

Before using Azure CLI, you need to authenticate with your Azure account. You can do this by using the az login command, which opens a web browser for you to sign in with your Azure credentials.

Azure CLI Usage Pattern

$ az [group] [subgroup] [command]

Example – to create a new resource group

$ az group create


$ brew update && brew install azure-cli

Azure Functions Core Tools CLI

Here's what you can do directly with Azure Functions Core Tools CLI:

  • Create new function projects and functions.
  • Run and debug functions locally.
  • Deploy functions to Azure.

Azure Functions Core Tools lets you develop and test your functions on your local computer from the command prompt or terminal. Your local functions can connect to live Azure services, and you can debug your functions on your local computer using the full Functions runtime. You can even deploy a function app to your Azure subscription.


The specific prerequisites for Core Tools depend on the features you plan to use:

  • One of the following tools for creating Azure resources:
  • Install extensions: To manually install extensions by using Azure Functions Core Tools, you must have the .NET 6.0 SDK installed. The .NET SDK is used by Core Tools to install extensions from NuGet. You don't need to know .NET to use Azure Functions extensions.
