Azure Logic app standard - set vnetPrivatePortsCount via Terraform

We have a requirement to set the vnetPrivatePortsCount which is a Configuration setting of Standard logic app. However, so far we could not find a way to set it via terraform. We use azurerm_logic_app_standard object to create Logic apps so we need an option to set it via that.

We have tried doing below but that does not work

site_config {
vnet_private_ports_count = 2
}

Is this property not available via terraform or am I missing something? Our terraform version is 1.8.5 and azurerm version is 3.106.1

Azure Logic app standard - set vnetPrivatePortsCount via Terraform

As per the documentation by hashicorp the vnet_private_ports_count for logic App standard doesn't support as this feature need to be added.

Meanwhile we can leverage the same requirement using the CLI commands using null resource.

Terraform configuration:

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "example" {
  name     = var.resource_group_name
  location = var.location
}

resource "azurerm_app_service_plan" "example" {
  name                = var.app_service_plan_name
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  sku {
    tier = "WorkflowStandard"
    size = "WS1"
  }
}

resource "azurerm_storage_account" "example" {
  name                     = var.storage_account_name
  resource_group_name      = azurerm_resource_group.example.name
  location                 = azurerm_resource_group.example.location
  account_tier             = "Standard"
  account_replication_type = "LRS"
}

resource "azurerm_logic_app_standard" "example" {
  name                = var.logic_app_name
  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

  identity {
    type = "SystemAssigned"
  }

  site_config {
    always_on = true
  }
}

resource "null_resource" "set_vnet_private_ports_count" {
  provisioner "local-exec" {
    interpreter = ["pwsh", "-Command"]
    command = <<EOT
      az resource update --resource-group ${azurerm_resource_group.example.name} --name ${azurerm_logic_app_standard.example.name} --resource-type 'Microsoft.Web/sites' --set properties.siteConfig.vnetPrivatePortsCount=2
    EOT
  }

  depends_on = [azurerm_logic_app_standard.example]
}
