How to do it…

To create the module, perform the following steps:

1. In a new folder called moduledemo, create the Modules and webapp folders.

2. In the webapp folder, create a new variables.tf file with the following code:

variable "resource_group_name" {
  description = "Resource group name"
}

variable "location" {
  description = "Location of Azure resource"
  default     = "West Europe"
}

variable "service_plan_name" {
  description = "Service plan name"
}

variable "app_name" {
  description = "Name of application"
}

3. Then, create the main.tf file with the following code:

resource "azurerm_app_service_plan" "plan-app" {
  name                = var.service_plan_name
  location            = var.location
  resource_group_name = var.resource_group_name
  sku {
    tier = "Standard"
    size = "S1"
  }
}

resource "azurerm_app_service" "app" {
...
