Introduction

This article provides a comprehensive guide to creating and using Azure DevOps pipelines for efficient application deployment. We will explore YAML pipeline creation and a hands-on example of deploying applications using Azure Pipelines.

Creating YAML Pipelines

YAML pipelines offer a declarative way to define your CI/CD process. They are version-controlled, reusable, and easy to share.

trigger:

     - main

pool:

      vmImage: 'ubuntu-latest'

  steps:

       - script: echo Hello, world!

           displayName: 'Run a one-line script'

Hands-on: Deploying Applications with Azure Pipelines

Let's deploy a simple Node.js application to Azure App Service using Azure Pipelines.

1. Create an Azure App Service.
2. Create an Azure DevOps project.
3. Create a YAML pipeline with tasks for building, testing, and deploying your application.
4. Connect your pipeline to your Azure App Service.
5. Run the pipeline.

steps:

   - task: NodeTool@0

       inputs:

            versionSpec: '16.x' # Specify the Node.js version

- script: npm install

displayName: 'npm install'

- script: npm run build

displayName: 'npm run build'

- task: AzureWebApp@1

inputs:

   appName: 'your-app-name'

   resourceGroupName: 'your-resource-group'

   deployToSlotOrASE: false

   package: '$(Build.ArtifactStagingDirectory)/WebApp'

Summary

• YAML pipelines provide a structured way to define your CI/CD process.
• Azure Pipelines offers seamless integration with Azure services.
• Always follow best practices for security and maintainability.
