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

Pause the services

$ docker-compose pause
Pausing Nginx   ... done
Pausing Mysqldb ... done

Checking container status

$ docker-compose ps
 Name               Command             State                     Ports
