# 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
|
|
|
|
1. Put the [binary](https://gobuilder.me/get/github.com/Luzifer/rsyslog_cron/rsyslog_cron_master_linux-amd64) into your container
|
|
2. Generate a YAML file containing the cron definition
|
|
3. Watch your crons get executed in your log stream
|
|
|
|
## Config format
|
|
|
|
```yaml
|
|
---
|
|
rsyslog_target: logs.myserver.com:12345
|
|
log_format: '<{{ syslogpri .Severity }}>{{ .Date.Format "Jan 02 15:04:05" }} {{ .Hostname }} {{ .JobName }}: {{ .Message }}'
|
|
jobs:
|
|
- name: date
|
|
schedule: "0 * * * * *"
|
|
cmd: "/bin/date"
|
|
args:
|
|
- "+%+"
|
|
```
|
|
|
|
- `rsyslog_target` - needs to be a rsyslog endpoint supporting TCP plain connections like Loggly or Papertrail does.
|
|
- `log_format` - format to use for generating the log line (above shown is default and does not need to be provided)
|
|
- `schedule` - consists of 6 instead of the normal 5 fields:
|
|
|
|
```
|
|
field allowed values
|
