How to examine the Docker daemon log file
+++++++++++++++++++++++++++++++++++++++++++
Docker daemon log locations depend on the operating system. A good outline is in this stackoverflow question (http://stackoverflow.com/a/30970134/235000) on the matter. In summary:
Older Ubuntu - /var/log/upstart/docker.log
Boot2Docker - /var/log/docker.log
Debian GNU/Linux - /var/log/daemon.log
CentOS - /var/log/daemon.log | grep docker
Fedora - journalctl -fu docker.service
Red Hat Enterprise Linux Server - /var/log/messages | grep docker
OpenSuSE/Ubuntu - journalctl -fu docker.service
