Luzifer / rsyslog_cron
This project is a quick and dirty replacement for running a cron daemon inside docker containers.
Advantages
- It logs the output of the jobs into a remote syslog target (like Papertrail) using TCP syslog
- Crons can be started on seconds, not only on minutes like a conventional cron
- Due to the logs cron jobs can get debugged
Usage
- Put the binary into your container
- Generate a YAML file containing the cron definition
- Watch your crons get executed in your log stream
Config format
---
rsyslog_target: logs.myserver.com:12345
jobs:
- name: date
schedule: "0 * * * * *"
cmd: "/bin/date"
args:
- "+%+"
The rsyslog_target
parameter needs to be a rsyslog endpoint supporting TCP plain connections like Loggly or Papertrail does.
The schedule
parameter consists of 6 instead of the normal 5 fields:
field allowed values
