When working with Docker containers, you can run docker compose down before switching off your laptop to avoid potential issues like port conflicts or network errors when starting them again.

Running docker compose down before shutting down is a more cautious approach than simply shutting down your laptop when containers are still running, as it:

• Ensures no containers are left running

• Frees up all ports and networks immediately

After running docker compose down, you can also confirm no containers are running by running docker ps.
