Azure Function App

This Terraform module creates an Azure Function App with its App Service Plan, a consumption plan by default. A Storage Account and an Application Insights are required and are created if not provided. This module allows to deploy a application from a local or remote ZIP file that will be stored on the associated storage account.

You can create an Azure Function without plan by using the submodule modules/functionapp.

Azure Functions v3 are now supported by this module and is the default one.

Limitations

Based on a current limitation, you cannot mix Windows and Linux apps in the same resource group.

Usage

This module is optimized to work with the Claranet terraform-wrapper tool which set some terraform variables in the environment needed by this module. More details about variables set by the terraform-wrapper available in the documentation.

⚠️ Since modules version v8.0.0, we do not maintain/check anymore the compatibility with Hashicorp Terraform. Instead, we recommend to use OpenTofu.
