Learning Docker Compose by Building a Simple Todo App

Right now, I’m learning Docker Compose by running a simple multi-container Todo application. The project includes a Node.js backend, MongoDB for the database, and Nginx as the web server. By using Docker Compose commands, I was able to start all services together, check their status, and confirm that each container was running and mapped to the correct ports. I also learned how Docker handles logs and service orchestration, and I came across a warning about the Compose file version, which helped me understand recent changes in Docker Compose behavior.
