Terraform On Azure – Creating A WebApp

Introduction

 

Azure WebApp is a steadily used cloud service that helps us in internet hosting our utility code as a Platform Service providing. Within the improvement atmosphere, we could create an Azure WebApp utilizing the portal and deploy our code. Nevertheless, once we are coping with the manufacturing environments, we should take an Infrastructure as Code (IaC) method to automate the creation of Azure WebApp. On this article allow us to discover how we are able to create an Azure WebApp utilizing Terraform.

 

Within the earlier article, we explored the idea of Infrastructure as Code (IaC) and how you can get began with Infrastructure as Code (IaC) utilizing Terraform. We took a easy use case of how you can create a Useful resource Group utilizing Terraform. The next is the hyperlink to the earlier article of this sequence.

Create Azure WebApp utilizing Terraform

 

Allow us to create a easy Home windows-based Azure WebApp. The next are the sources that we should create earlier than making a WebApp.

  • Useful resource Group
  • App Service Plan

Any Azure useful resource should be created inside a Useful resource Group and an Azure WebApp should be related to an App Service Plan. An App Service Plan defines the compute, scaling, and different crucial necessities for Azure WebApp.

 

Log in to the Azure portal. Allow us to use Azure Cloud Shell to create sources utilizing Terraform. Azure Cloud Shell has Terraform put in and you needn’t do any set up or configuration to work with Terraform.

 

 

As soon as the Azure Cloud Shell opens up, choose Bash. Allow us to begin creating scripts to create an Azure WebApp. We will use a nano editor to create the Infrastructure as Code script for the WebApp utilizing Terraform.

 

Terraform On Azure - Creating A WebApp

 

Execute the next command to open a nano editor and create a file named myterraformscript.tf.

  1.   nano myterraformscript.tf

Add the next code to the nano editor. This could create a Useful resource Group. Change {ResourceGroup} with title of your Useful resource Group that you’re planning to create.

  1. terraform {    
  2.   required_providers {    
  3.     azurerm = {    
  4.       supply = “hashicorp/azurerm”    
  5.     }    
  6.   }    
  7. }    
  8. supplier “azurerm” {    
  9.   options {}    
  10. }    
  11. useful resource “azurerm_resource_group” “{ResourceGroup}” {    
  12.   title = “{ResourceGroup}”    
  13.   location = “eastus”    
  14. }    

Add the next code in nano editor to create an App Service Plan. Change {ResourceGroup} with title of your Useful resource Group that you’re planning to create. Change {AppServicePlanName} with title of the App Service Plan you might be planning to create.

  1. useful resource “azurerm_app_service_plan” “{AppServicePlanName}” {  
  2.   title                = “{AppServicePlanName}”  
  3.   location            = “eastus”  
  4.   resource_group_name = azurerm_resource_group.{ResourceGroup}.title  
  5.   
  6.   sku {  
  7.     tier = “Normal”  
  8.     measurement = “S1”  
  9.   }  
  10. }   

Add the next code to create a WebApp. Change {ResourceGroup} with title of your Useful resource Group that you’re planning to create. Change {AppServicePlanName} with title of the App Service Plan you might be planning to create. Change {WebAppName} with title of the WebApp that you’re planning to create. You might be additionally including few appsetting keys and values.

  1. useful resource “azurerm_app_service” “{WebAppName}” {  
  2.   title                = “{WebAppName}”  
  3.   location            = “eastus”  
  4.   resource_group_name = azurerm_resource_group.{ResourceGroup}.title  
  5.   app_service_plan_id = azurerm_app_service_plan.{AppServicePlanName}.id  
  6.   
  7.   app_settings = {  
  8.     “DeviceName” = “SampleDevice”,  
  9.     “DeviceId” = “2”  
  10.   }  
  11. }  

The next is the script file that you just created. You’ll be able to consult with the hooked up script file and check out the pattern. Change {ResourceGroup} with the title of your Useful resource Group that you’re planning to create. Change {AppServicePlanName} with the title of the App Service Plan you might be planning to create. Change {WebAppName} with the title of the WebApp that you’re planning to create. You might be additionally including just a few appsetting keys and values.

  1. terraform {    
  2.   required_providers {    
  3.     azurerm = {    
  4.       supply = “hashicorp/azurerm”    
  5.     }    
  6.   }    
  7. }    
  8. supplier “azurerm” {    
  9.   options {}    
  10. }    
  11. useful resource “azurerm_resource_group” “{ResourceGroup}” {    
  12.   title = “{ResourceGroup}”    
  13.   location = “eastus”    
  14. }   
  15. useful resource “azurerm_app_service_plan” “{AppServicePlanName}” {  
  16.   title                = “{AppServicePlanName}”  
  17.   location            = “eastus”  
  18.   resource_group_name = azurerm_resource_group.{ResourceGroup}.title  
  19.   
  20.   sku {  
  21.     tier = “Normal”  
  22.     measurement = “S1”  
  23.   }  
  24. }  
  25.   
  26. useful resource “azurerm_app_service” “{WebAppName}” {  
  27.   title                = “{WebAppName}”  
  28.   location            = “eastus”  
  29.   resource_group_name = azurerm_resource_group.{ResourceGroup}.title  
  30.   app_service_plan_id = azurerm_app_service_plan.{AppServicePlanName}.id  
  31.   
  32.   app_settings = {  
  33.     “DeviceName” = “SampleDevice”,  
  34.     “DeviceId” = “2”  
  35.   }  
  36. }  

Run the next command to provoke Terraform. This could fetch all dependencies wanted to execute the Terraform script.

Now allow us to create an execution plan for Terraform. Allow us to present the title of the execution plan within the out parameter.

  1. terraform plan –out myrg.tfplan   

Execute the execution plan utilizing the next command,

  1. terraform apply “myrg.tfplan”  

The WebApp will get created contained in the Useful resource Group utilizing the App Service Plan that we’ve got specified.
