docker-compose build
docker-compose build myservice
docker-compose up
if you want to run the container in the background (no console output), do this (-d is 'daemon' or background mode):
docker-compose up -d
docker-compose up myservice
attach to a running service, assuming bash is in the container (will need a new terminal window unless you ran the services in daemon mode)
docker-compose exec myservice /bin/bash
