This Terraform feature 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.
Azure Functions v3 are now supported by this module and is the default one.
| Module version | Terraform version | AzureRM version |
|---|---|---|
| >= 4.x.x | 0.13.x | >= 2.0 |
| >= 3.x.x | 0.12.x | >= 2.0 |
| >= 2.x.x | 0.12.x | < 2.0 |
| < 2.x.x | 0.11.x | < 2.0 |
Based on a current limitation, you cannot mix Windows and Linux apps in the same resource group.
Limitations documentation: docs.microsoft.com/en-us/azure/app-service/containers/app-service-linux-intro#limitations
Due to a bug introduced in AzureRM v2.18.0, you need to force the version to 2.17.0 if you want to create a Linux FunctionApp. GitHub Issue
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.
You can use this module by including it this way:
