You would not think this would be super difficult or, at the least Terraform’s documentation would cover such a common use case. But, I found it to be false, so I figured I would share the necessary changes needed.
First, some background – I am using a Terraform script to deploy a variety of Azure resources to support an internal bootcamp I will be giving at West Monroe in August.
Here is the completed Terraform block to deploy the V2 Azure Function:

| resource "azurerm_function_app" "main" { | |
| name = "${var.resource-prefix}-analyticsapp" | |
| location = "${azurerm_resource_group.main.location}" | |
| resource_group_name = "${azurerm_resource_group.main.name}" | |
| app_service_plan_id = "${azurerm_app_service_plan.main.id}" | |
| storage_connection_string = "${azurerm_storage_account.main.primary_connection_string}" | |
| version = "~2" | |
| app_settings { | |
| FUNCTIONS_EXTENSION_VERSION = "~2" | |
| FUNCTIONS_WORKER_RUNTIME = "dotnet" | |
| } | |
| site_config { | |
| always_on = true | |
| linux_fx_version = "DOCKER|mcr.microsoft.com/azure-functions/dotnet:2.0-appservice" | |
| use_32_bit_worker_process = true | |
| } | |
| } |
This isnt something that is covered in the documentation that, in addition to specifying version we also need to include the linux_fx_versionin site_config.
I do not know if this is necessary if you use a Windows based App Service Plan (I am using Linux and sharing it with my App Service).
I found immense frustration in figuring this out and found myself annoyed that I could not find anything by V1 examples in the Terraform docs.
