⚡ Quick Start

Prerequisites

• Docker Desktop installed
• Ports 3000, 5000, 27017 available

Run the full stack

# Clone the repo
git clone https://github.com/devops-swapnil/staynest.git
cd staynest

# Build and start all containers
docker compose up --build

# The seed job runs automatically on first start

Open http://localhost:3000 in your browser.

Tear down

docker compose down -v   # also removes volumes

🔌 API Endpoints

Base URL: http://localhost:5000/api

Method	Endpoint	Description
GET	/listings	Get all listings
GET	/listings?category=Beach	Filter by category
GET	/listings?search=Maldives	Search by keyword
GET	/listings/:id	Get single listing
POST	/listings	Create listing
PUT	/listings/:id	Update listing
DELETE	/listings/:id	Delete listing
GET	/health	Health check

🔐 MongoDB Credentials

Root User	root
Root Password	rootpassword
App User	staynest_user
App Password	staynest_pass
Database	staynest
Auth Source	staynest

🐳 Docker Details

• Frontend: nginx:1.25-alpine — serves static files, proxies /api/* to backend
• Backend: node:20-alpine (multi-stage build) — runs as non-root user for security
• MongoDB: mongo:7.0 with persistent volume and health checks
• Seed: One-shot job that seeds 30 listings on first start
• All services communicate over an isolated Docker bridge network

📋 DevOps Highlights

• Multi-stage Docker builds (smaller images)
• Health checks on all services
• Dependency ordering with condition: service_healthy
• Non-root container user (security best practice)
• Nginx gzip compression & static asset caching
• Environment-based configuration via .env
• Persistent MongoDB volume
