Docker Containerization

This skill ensures that applications run consistently across different machines by using container technology.

Instructions

1. Write a Dockerfile for the application.
2. Use multi-stage builds to reduce image size.
3. Configure docker-compose.yml for multi-container services.
4. Manage volumes for data persistence.
5. Secure containers by running as a non-root user.

Examples

• "Containerize this Node.js app and its PostgreSQL database."
• "Optimize this Docker image to be under 100MB."
