Docker containers automatically exit when their main process completes, as they are designed to run specific tasks and terminate upon completion. The article presents three methods to keep containers
running indefinitely: using 'sleep infinity', 'tail -f /dev/null', or 'cat' commands, which are useful for development and debugging.
