  db_data:

Bringing up the containers​

$ docker-compose up -d

----------------------------------------------------------------------------------------
Mysqldb   docker-entrypoint.sh mysqld   Up      0.0.0.0:3306->3306/tcp, 33060/tcp       
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
