DEPLOYING A WEB APPLICATION WITH ARM TEMPLATE AND AZURE CLI

INTRODUCTION

Azure provides a robust environment for deploying and managing web applications. ARM templates are JSON or Bicep files that specify the infrastructure and configuration of your Azure resources. They enable repeatable deployments and infrastructure-as-code (IaC) practices. Azure CLI complements this approach by providing commands to manage Azure resources from a terminal or shell script.

Deploying a web app using these tools ensures:

• Consistency: Every deployment follows the exact specifications defined in the template.


• Automation: Reduces manual configuration errors and saves time.


• Scalability: Easily modify the template to scale resources or deploy additional environments.

Pre-requisites

• Azure Subscription: An active Azure account. .


• Text Editor: For editing ARM templates (e.g., VS Code).


• Basic Knowledge: Familiarity with JSON and Azure Web Apps.

Step-by-Step Guide

• 
  Step 1: Prepare the ARM Template
  Create a JSON file for your ARM template (e.g., webapp-template.json).
  Define the required resources. A simple ARM template for an Azure Web App might look like this:

Save the file.

• 
  Step 3: Log in to Azure

1. Open a terminal.


2. Log in to Azure:

az login

• 
  Step 4: Create a Resource Group

Create a resource group where the web app will be deployed:

• 
  Step 6: Connect Github Repository to Azure using this code:
  az webapp deployment source config --name seyiwebapp555 --resource-group websiteRG --repo-url
  
  
  
  
  
  • 
    Step 7: Test the Web App
    Navigate to the web app URL provided in the Azure Portal or from the CLI output.
  
  
  
  
  
  
  

  Confirm that the web app is running.

  
  
  

  

  
  
  

  Conclusion
  
  This guide demonstrates how to deploy a web app using ARM templates and Azure CLI. By adopting these tools, you ensure a consistent and automated approach to managing Azure resources. You can extend the template to include additional configurations like custom domains, SSL bindings, or CI/CD pipelines.
