Understanding `docker compose up` 🐳

There are many advantages to using Docker with your app, and multiple ways to get started. You can use the Docker Desktop app or the Docker extension in VS Code.

So, what happens when you run the `docker compose up` command?

- The first time you run it, Docker may take some time to download base images and build containers. However, future runs will be faster due to Docker's caching mechanisms.
- It starts all the containers defined in the `docker-compose.yml` file.
- If the project requires connections to other containers, Docker establishes those connections.
- If the images aren't already built, Docker builds them as part of the process.

🛑 To stop the containers: 
- Press `CTRL + C` on your keyboard, which allows Docker to stop the containers gracefully.
- Alternatively, you can use `docker compose down` to remove containers, networks, and volumes, or `docker compose stop` to halt the containers without removing them.

🔎 Running into port issues?
Use this command to check if a specific port is still active:
`netstat -ano | findstr :3000` (replace 3000 with your port number).
