Optimized Dockerfile Implementation

Description

Created optimized and secure Docker images for a Node.js app using official base images, caching strategies, and multi-stage builds. Reduced image size, improved build speed, and enforced security best practices.

Tools and Technologies

• Docker
• Node.js
• Express.js
• Linux Command Line (bash)
• Text Editors (nano, vim)

Project Walk-through

1. Official base image usage for security and reliability


2. Layer optimization to reduce image size and improve build speed


3. Docker caching strategies for faster iterative builds


4. Multi-stage builds for production-ready images


5. Security practices including non-root users and proper permissions
