Issue in deploying azure function through terraform with app settings - azure

Question

I am Following this docs page to deploy azure function with app settings https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/function_app
My terraform file looks like :
terraform {
required_providers {
azurerm = {
source = "hashicorp/azurerm"
version = "3.10.0"
}
}
}
provider "azurerm" {
}
resource "azurerm_resource_group" "example" {
name = "azure-functions-test-rg"
location = "West Europe"
}
resource "azurerm_storage_account" "example" {
name = "funcdemo123shafiq"
resource_group_name = azurerm_resource_group.example.name
location = azurerm_resource_group.example.location
account_tier = "Standard"
account_replication_type = "LRS"
}
resource "azurerm_app_service_plan" "example" {
name = "azure-functions-test-service-plan"
location = azurerm_resource_group.example.location
resource_group_name = azurerm_resource_group.example.name
sku {
tier = "Standard"
size = "S1"
}
}
resource "azurerm_function_app" "example" {
name = "test-azure-shafiq123"
location = azurerm_resource_group.example.location
resource_group_name = azurerm_resource_group.example.name
app_service_plan_id = azurerm_app_service_plan.example.id
storage_account_name = azurerm_storage_account.example.name
storage_account_access_key = azurerm_storage_account.example.primary_access_key
os_type = "linux"
version = "~4"
app_settings {
FUNCTIONS_WORKER_RUNTIME = "python"
TESTING_KEY = "TESTING_VALUE"
}
site_config {
linux_fx_version = "python|3.9"
}
}
When try to deploy this through terraform apply command , I am getting this error.
│ Error: Unsupported block type
│
│ on main.tf line 46, in resource "azurerm_function_app" "example":
│ 46: app_settings {

│ Blocks of type "app_settings" are not expected here. Did you mean to define argument "app_settings"? If so, use the equals sign to assign it a value.

Answer 1

app_setting is supported on specific version of Terraform AzureRM provider. There is bug fixed availble for those version. I have used 3.3.0 provider version and it is working for me as expected and also you can't configure the value of site_config.Its value will be decide automatically based on the result of applying this configuration, same you can check in the updated document of Terraform
main.tf
terraform {
required_providers {
azurerm = {
source = "hashicorp/azurerm"
version = "3.3.0"
}
}
}
provider "azurerm" {
features{}
}
data "azurerm_resource_group" "example" {
