Deploying Azure AppService using Terraform Script

Let's first find out what an azure app service is !!  
Azure AppService is a Platform as a service (PaaS) cloud computing-based platform for hosting websites, created and managed by Microsoft. Azure appService includes multiple services(Azure Website, Azure Mobile services and Azure BizTalk ) that were previously delivered separately.

Being involved with Terraform configurations is done in three steps:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1> Create a configuration 2> Initialize the terraform state 3> Apply the configuration

1. Create an Azure App Service
~~~~~~~~~~~~~~~~~~~~~~~~
Now that we’ve seen what an Azure App Service is, let us dive deep and create a new App Service in Azure.

Create a terraform script file named myappservice.tf

vim myappservice.tf

To provision an appservice we need.

(a) Resource Group (b) AppService Plan (c) App Service

Now make the following configuration entries here.

#This section creates a azure Resource Group named "myrg"

resource "azurerm_resource_group" "stage" {   name     = "myrg"   location = "West Europe" }

#Create a App Service Plan named "myplan".

resource "azurerm_app_service_plan" "stage" {   name                = "myplan"   location            = "${azurerm_resource_group.stage.location}"   resource_group_name = "${azurerm_resource_group.stage.name}"   sku {     tier = "Free"     size = "F1"   } }

#Create a App Service named "myappsrvc"

resource "azurerm_app_service" "stage" {   name                = "myappsrvc"   location            = "${azurerm_resource_group.stage.location}"   resource_group_name = "${azurerm_resource_group.stage.name}"   app_service_plan_id = "${azurerm_app_service_plan.stage.id}" }

2. Initialize the terraform state
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Before we start applying this configuration to your azure environment we need to initialliz terraform in the current folder in order to get it working with our script:

terraform init 

This will download the required modules for our repository and setup any local files that our terraform script needs.

terraform init

3. Apply the configuration
~~~~~~~~~~~~~~~~~~~~~~~~~~    
Once initialization is done. it is time to apply our configuration to our azure environment.

terraform apply

This will deploy a new desired state for your environment.
