Dockerization Lab is an educational repository designed to teach you how to containerize your applications using Docker and Docker Compose, step by step.
It starts with the fundamentals, introduces Docker Compose, and then applies everything to a real-world NestJS + PostgreSQL project.
- Understand what Docker is and how it works
- Learn about images, containers, volumes, and networks
- Use Docker Compose to manage multi-container applications
- Apply Dockerization principles to a NestJS backend project
- Build a reusable structure for future apps
