Bringup the containers

$ docker-compose up -d

Checking container status

$  docker-compose ps
 Name               Command             State                    Ports

Nginx     nginx -g daemon off;          Up      0.0.0.0:443->443/tcp, 0.0.0.0:80->80/tcp

Listout the services

$  docker-compose ps --services
webserver
dbserver

Stop the container of a single service

$  docker-compose stop webserver
Stopping Nginx ... done

Checking container status

$  docker-compose ps
 Name               Command             State                  Ports
