Docker - Logging and Monitoring

A user runs:
docker run --log-driver=syslog --log-opt syslog-facility=daemon myimage
But logs are not appearing in syslog. What is a possible error?

ADocker does not support syslog logging driver

BThe syslog-facility option is invalid and causes failure

CThe --log-driver flag must be set to json-file for syslog

DThe syslog server is not configured to accept logs from Docker

Step-by-Step Solution

Solution:

Step 1: Confirm Docker supports syslog driver and syntax
Docker supports syslog driver and the option syslog-facility is valid.
Step 2: Check syslog server configuration
If syslog server is not set to accept Docker logs, logs won't appear.
Final Answer:
The syslog server is not configured to accept logs from Docker -> Option D
Quick Check:
Syslog server must accept Docker logs for syslog driver to work [OK]

Quick Trick: Syslog server must be configured to receive Docker logs [OK]

Common Mistakes:

Assuming syslog-facility is invalid
Thinking json-file needed for syslog
Believing Docker lacks syslog support
