🚀 Azure DevOps CI/CD Demo: Node.js & Docker

A production-grade demonstration of Modern DevOps practices using Azure DevOps, Docker, and Node.js. This repository showcases a complete automated lifecycle—from code commit to containerized deployment on Azure App Service.

🌟 Key Features

• Automated CI Pipeline: Multi-stage YAML pipeline for building, testing, and containerizing.
• Docker Integration: Optimized Dockerfile for Node.js production environments.
• Advanced CD Strategy:
  • Deployment Slots: Zero-downtime deployments using Azure App Service staging slots.
  • Manual Approvals: Integrated gatekeeping for production releases.
  • Automated Rollbacks: Logic to handle deployment failures gracefully.
• Observability: Built-in health check endpoints for infrastructure monitoring.

🏗️ Architecture Overview

The pipeline is split into three main stages:

1. Build & Test: Installs dependencies, executes unit tests, builds the Docker image, and pushes it to Azure Container Registry (ACR).
2. Deploy to Staging: Deploys the latest container to a staging slot for validation.
3. Production Release: Requires manual sign-off before swapping slots to live traffic.

🛠️ Tech Stack

• Backend: Node.js, Express.js
• Testing: Mocha, Supertest
• Containerization: Docker
• Orchestration/CI-CD: Azure Pipelines (YAML)
• Cloud: Azure App Service, Azure Container Registry (ACR)

🚀 Getting Started

Local Development

1. Clone the repo:

   git clone https://github.com/ihkokil/azure-devops-ci-cd-demo.git

2. Install dependencies:

   npm install

3. Run tests:

   npm test

4. Start the app:

   npm start

Pipeline Configuration

To mirror this pipeline in your own Azure DevOps organization:

1. Create a Service Connection to your Azure Subscription and Docker Registry.
2. Update the variables in azure-pipelines.yml (Registry URL, App Name, etc.).
3. Configure the production environment with Approvals and Checks.
