Use Docker containers to create and launch a basic multi-tier web application (frontend, backend, and database). To manage volumes, networks, and services, use Docker Compose. This project teaches you about multi-container orchestration, persistent storage, and container linking.

Create a pipeline for continuous integration and deployment by integrating Docker and Jenkins. The pipeline should deploy containers in a test/production environment, automatically create Docker images from source code, and push them to Docker Hub (or a private registry). Your DevOps automation skills are strengthened by this project.

Create and implement a microservices-based application (such as a chat or e-commerce app) with Docker Swarm orchestration. Execute scaling, load balancing, and rolling updates among several nodes. This project provides practical experience with real-world scaling challenges and container orchestration.
