How to check logs
In order to view containers’ logs,
docker logs is the best bet to go.
Before viewing logs, running containers could be seen by running
docker ps and
docker ps -a if wished to view stopped containers as well
docker logs <container name> --tail <number of lines to tail> -f # -f is for following
less /var/log/ocl/web_debug.log.`date +%Y-%m-%d`_*
