Deploying a web application with a CI/CD pipeline on Azure App Service using GitHub involves several steps. Here's a detailed guide to help you through the process:

Step 1: Create an Azure App Service

Login to Azure Portal:

• Go to the Azure Portal.
• Login with your Azure credentials.

Create a New Resource:

• In the Azure portal, click on "Create a resource".
• Search for "App Service" and select it.
• Click "Create" to start the configuration.

Configure the App Service:

• Subscription: Choose your Azure subscription.
• Resource Group: Either create a new resource group or use an existing one.
• Name: Enter a unique name for your App Service.
• Publish: Select "Code".
• Runtime Stack: Choose the runtime stack that your application uses (e.g., .NET, Node.js, Python).
• Operating System: Select the OS (Windows/Linux).
• Region: Choose a region where the App Service will be hosted.
• Pricing Tier: Choose a pricing tier based on your needs (e.g., Free, Shared, Basic). Review and Create:
• Click on "Review + Create" to validate your settings.
• Once validation passes, click "Create".

Step 2:Create and configure webapp

• In the basics tab, choose a resource group and name.
• choose a programming language(PHP).
• Review and create

Step 3: Set Up GitHub Actions for CI/CD

**Create your repository, add a README file
After creating, copy the url created

Step 4: Virtual studio code

• On the visual studio code, on the search bar,type the repostory name you created and open.
• Switch your terminal to gitbash. run these commands mkdir project cd project
  • Open the folder on the VSCode. run the above linux commands cd mywebapp touch index.php nano cat index.php

NOTE: Remember to stage and commit yor git
git add .
git commit -m"comment"
git init

Step 5: On the webapp page in your azure portal

• Go to deployment center
• Fill and save

By following these steps, you should have a fully operational CI/CD pipeline for your web app on Azure using GitHub Actions. This setup automates the process of building, testing, and deploying your application whenever you push changes to your repository.
