Getting started¶

Install the required tools and create the Azure resources for a Go function application.

Prerequisites¶

Before creating your first function, install:

Go 1.24 or later
Azure Functions Core Tools version 4.12.0 or later, which includes Go worker support
Azure CLI 2.87.0 or later if you want to create and manage Azure resources from the command line

Install Azure Functions Core Tools using npm:

npm install --global azure-functions-core-tools@4 --unsafe-perm true

Confirm that both tools are available:

go version
func --version
az version

Create a Function App in Azure¶

Go support is currently in preview and uses the native Go runtime on the Flex Consumption plan.

The simplest way to create a Function App is through the Azure portal, which automates the supporting resource and role assignment setup.

You can also provision the Function App and its dependencies using:

The Azure CLI
Bicep
Azure Resource Manager (ARM) templates
Terraform or another infrastructure-as-code tool

After creating the Function App, continue developing and testing locally. The Azure resource is needed only when you are ready to deploy the application.
