graylog 是一個很不錯的日志系統，但是我們實際開發中，可能需要進行測試，但是直接部署一個graylog 可能有點太費事
（依賴es，mongo），有一個golang mock 服務的實現包 github.com/lintianzhi/graylogd
以下是一個demo server的構建以及容器鏡像，可以直接使用
代碼
- go mod
module github.com/rongfengliang/graylogd
go 1.14
require (
github.com/bmizerany/assert v0.0.0-20160611221934-b7ed37b82869 // indirect
github.com/kr/pretty v0.2.0 // indirect
github.com/lintianzhi/graylogd v0.0.0-20180503131252-dc68342f04dc
github.com/robertkowalski/graylog-golang v0.0.0-20151121031040-e5295cfa2827
github.com/stretchr/testify v1.6.1
)
- main.go
package main
import (
"fmt"
"net"
"github.com/lintianzhi/graylogd"
)
func main() {
conf := graylogd.Config{
ListenAddr: ":12201",
// handle raw message
HandleRaw: func(b []byte) {
fmt.Println(string(b))
fmt.Println(len(b))
},
HandleGELF: func(gelf *graylogd.GelfLog, addi map[string]interface{}) {
fmt.Println(gelf)
fmt.Println(addi)
},
HandleError: func(addr *net.UDPAddr, err error) {
fmt.Println("err:", err)
},
}
logd, _ := graylogd.NewGraylogd(conf)
err := logd.Run()
if err != nil {
fmt.Println("run failed:", err)
return
}
select {}
}

說明
已經push 的docker 鏡像dalongrong/graylogd 可以直接使用，參考運行
docker run -d -p 12201:12201/udp dalongrong/graylogd
