az-functionapp

TLDR

List all function apps

$ az functionapp list

Create a function app (consumption plan)

$ az functionapp create --resource-group [rg_name] --consumption-plan-location [eastus] --runtime [node] --functions-version [4] --name [app_name] --storage-account [storage_name]

Create a function app on an App Service plan

$ az functionapp create --resource-group [rg_name] --plan [plan_name] --runtime [python] --runtime-version [3.11] --functions-version [4] --name [app_name] --storage-account [storage_name]

Show function app details

$ az functionapp show --name [app_name] --resource-group [rg_name]

Deploy code from a zip file

$ az functionapp deployment source config-zip --name [app_name] --resource-group [rg_name] --src [function.zip]

Restart a function app

$ az functionapp restart --name [app_name] --resource-group [rg_name]

View application settings

$ az functionapp config appsettings list --name [app_name] --resource-group [rg_name]

Set an application setting

$ az functionapp config appsettings set --name [app_name] --resource-group [rg_name] --settings "[KEY=value]"

SYNOPSIS

az functionapp subcommand [options]

az functionapp is a subcommand of the Azure CLI that manages Azure Functions apps. Azure Functions is a serverless compute service that runs event-triggered code without managing infrastructure.
Function apps host one or more functions that share configuration, deployment, and scaling. They can run on consumption plans (pay per execution, auto-scale), premium plans (pre-warmed instances, VNet integration), or dedicated App Service plans.
Supported runtimes include .NET, Node.js, Python, Java, PowerShell, and custom handlers. Functions can be triggered by HTTP requests, timers, queues, blobs, Event Grid, and other Azure services.

PARAMETERS

list

List all function apps.

create

Create a new function app.

delete

Remove a function app.

show

Get function app details.

restart

Restart the function app.

start

Start a stopped function app.

stop

Stop a running function app.

deployment source config-zip

Deploy from zip file.

config appsettings list

List application settings.

config appsettings set

Set application settings.

function list

List functions in the app.

--name name

Function app name (globally unique).

--resource-group rg

Resource group name.

--consumption-plan-location location

Region for consumption plan.

--plan plan

App Service plan name.

--runtime runtime

Language runtime (node, python, dotnet, java, powershell).

--runtime-version version

Runtime version.

--functions-version version

Azure Functions runtime version (4).

--storage-account storage

Storage account for function state.

CAVEATS

Function app names must be globally unique. Consumption plan has cold start latency. Storage account is required for triggers and state. Some features like VNet integration require Premium or App Service plans. Linux consumption plan has limited region availability. Functions version 4 requires runtime-specific version compatibility.

HISTORY

Azure Functions launched in March 2016 as Microsoft's serverless compute platform, inspired by AWS Lambda. Durable Functions for stateful workflows was added in 2017. Premium plan was introduced in 2019 for enterprise scenarios. Functions 4.0 with .NET 6 support released in November 2021. The service has expanded to support containers, Kubernetes via KEDA, and Azure Arc for hybrid deployments.
