Deploy Azure Functions from the CLI

Intermediate12 min

Create a serverless function app and deploy functions using Azure CLI and Azure Functions Core Tools.

Prerequisites

-Azure CLI installed
-Azure Functions Core Tools installed
-Active Azure subscription

Steps

Create a resource group and storage account

Functions require a storage account for triggers and state management.

$ az group create --name func-rg --location eastus && az storage account create --name funcstore$RANDOM --resource-group func-rg --sku Standard_LRS

Create the function app

Creates a consumption-plan function app that scales automatically and bills per execution.

$ az functionapp create --resource-group func-rg --consumption-plan-location eastus --runtime node --runtime-version 20 --functions-version 4 --name myfunc-unique --storage-account funcstore

Consumption plan is free for the first 1 million executions per month.

Initialize a local function project

Scaffolds a local project with the required configuration files.

$ func init MyFuncProject --worker-runtime node --language javascript

Create a function

Adds an HTTP-triggered function to the project.

$ cd MyFuncProject && func new --name HttpTrigger --template "HTTP trigger"

Deploy to Azure

Packages and deploys all functions in the project to the remote function app.

$ func azure functionapp publish myfunc-unique
