log

Dead simple logging package for streaming log to syslog Dependency free

Usage

Just import and use it No configuration needed No new terms to learn.

package main

import "github.com/subiz/log"

func main() {
	log.Info("ac123", "this is a log message", "cid", "cs123")

	var err error
	log.Err("ac123", err, "this is an err", "cid", "cs123")
}

Use Info to log info, use Err to log error. Pass account_id to the first parameter to partition the log stream. It helps you grep log more effeciently.

Config Dockerfile

In order to stream log from all containers to one centralized server (log-1), you must install rsyslog in every container and config it like bellow.

RUN apk update && apk add rsyslog

RUN echo $'\n$FileOwner root\n$FileGroup adm\n$FileCreateMode 0640\n$DirCreateMode 0755\n$Umask 0022\n$WorkDirectory /tmp\n$ActionQueueFileName justlog\n$ActionQueueMaxDiskSpace 1g\n$ActionQueueSaveOnShutdown on\n$ActionQueueType LinkedList\n$ActionResumeRetryCount -1\n$ActionResumeInterval 30\n*.* @log-1:514' >> /etc/rsyslog.conf
