Reliability options and Behaviour of the syslog logging driver

(Archbungle) #1

How reliable is the docker syslog driver when used with rsyslog, e.g logging from docker daemon to local6. facility via syslog on a linux host?
Specifically, when the docker syslog driver is unable to communicate with rsyslogd on the same physical server, does it discard logs, buffer them to disk or memory, or block docker resulting in docker crashing or containers crashing.

In addition, is there any detailed design documentation on the syslog driver itself for docker?

Thanks in advance for any insight!
