🐳 NodeSlim: Docker Multi-Stage Mastery

📋 Project Overview

This project demonstrates advanced Docker containerization techniques through a practical implementation of multi-stage builds for Node.js applications. By leveraging multi-stage builds, I've created a streamlined containerization process that significantly reduces image size and enhances deployment efficiency while maintaining robust functionality.

🎯 Key Objectives

• Implement efficient multi-stage Docker builds for Node.js applications
• Optimize container image size through strategic layer management
• Demonstrate professional-grade containerization practices
• Create a secure and production-ready deployment pipeline
• Establish a reusable pattern for Node.js application containerization

🏗️ Project Architecture

The architecture implements a Docker multi-stage build process that first copies the Node.js source code into a build stage using the full node:latest image. Then, for optimal production deployment, it transfers only the necessary artifacts to a lightweight node:slim image, resulting in a significantly smaller final image (~150MB) that runs a simple HTTP server on port 3000.

Docker Multi-Stage Build Node.js Architecture

💻 Technical Stack

• Runtime: Node.js with HTTP server implementation
• Containerization: Docker multi-stage builds
• Base Images:
  • Build: node:latest
  • Production: node:slim
• Networking: Exposed port 3000

🚀 Getting Started

🐳 Prerequisites

• Docker Engine 20.10.x or higher
• Node.js 14.x or higher (for local development)
• Git for version control

⚙️ Installation

1. Clone the repository:

   git clone https://github.com/TheToriqul/multi-stage-nodejs-build.git
   cd multi-stage-nodejs-build

2. Build the Docker image:

   docker build -t node-app .

3. Run the container:

   docker run -d -p 3000:3000 node-app

🎮 Usage

1. Access the application:

   curl http://localhost:3000

2. View container status:

   docker ps

For detailed commands and operations, refer to the reference-commands.md file.
