$ docker-compose build 		(1) 	: Build multi-container image
$ docker image ls 			: projectDirectoryName-imageName
$ docker-compose up -d 		(2)	: Start multi-container
$ docker-compose logs -f  		: See all (both) container's logs together
$ docker logs -f next-app_next 		: See only 'next-app_next' container's logs

$ docker-compose ps -a 			: show process/containers running by docker-compose
$ docker ps -a 				: show all process
$ docker down 				: stop multi-container

NB: - Though database take some times to start & ready, so 1st time may require refresh browser
	. To solve that issue we can use a package 'wait-for-it'
