How to do it…

To create multiple identical resources, perform the following steps:

1. In the variables.tf file, we add the following variable:

variable "nb_webapp" {
    description = "Number of App Service to create"
}

2. In the terraform.tfvars file, we give a value for this new variable as follows:

nb_webapp = 2

3. In the main.tf file, we modify the resource code of azurerm_app_service in the following way:

resource "azurerm_app_service" "app" {
  count = var.nb_webapp
  name = "${var.app_name}-${var.environement}-${count.index+1}"
  location = azurerm_resource_group.rg-app.location
  resource_group_name = azurerm_resource_group.rg-app.name
  app_service_plan_id = azurerm_app_service_plan.plan-app.id
}

4. (Optional:) In a new outputs.tf file, we add the output values with the following code:

output "app_service_names"{
 value = azurerm_app_service.app[*].name
}
