DOCKER SYSLOG NG START HOW TO
This is much easier then trying to figure out how to run a syslog process alongside your application inside your docker container (which docker probably isnt designed to do anyway). If I add print statements to the Python script, it gets sent to stdout as expected. If you could add a working configuration, that can start syslog-ng automatically during system startup, teach launchd how to stop syslog-ng, and how to restart or reload (syslog-ng-ctl stop/restart/reload), that would be a valuable contribution. That way, your syslog will print to stderr, which docker will then log by default (you dont need to run syslog process in docker for this).
Like this: sudo docker run -i -v /etc/alloy_listener/scripts:/scripts:ro alloy_listener /scripts/test.pyĮverything is fine, the container run and just sits there doing very little. When I execute an arbitrary Python script: import time I have already covered how to use syslog-ng in a Docker environment as a traditional central syslog server. Within that VM, I have a Docker image running stock Python 3.4.3: FROM python:3.4.3-slim This is the final blog post in a three-part series on logging in Docker using syslog-ng. On the other hand, remote logging drivers arrive with a minimalist feature set and you are not able to use the doc. docker run -rm -it -entrypoint /bin/sh balabit/syslog-ng openssl version OpenSSL 1.1. This post demonstrates how to ingest syslog messages in Seq. I have a Vagrant-created VM running stock Ubuntu Trusty 64, with one host CPU allocated to it. Why use syslog-ng for collecting Docker logs Docker already provides many drivers for logging, even for central log collection. Currently the syslog-ng-docker container is using openSSL version 1.1.0l, however support for TLSv1.3 was only introduced in openSSL version 1.1.1. Using, Seq is able to ingest syslog messages both RFC3164 and RFC5424 formats as structured logs.
