You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: master.go
    path of file: ./repos/learning/golang/practice/go-crontab/gopath/src/github.com/owenliang/crontab/master/main
    
    the code of the file until where you have to start completion: package main

import (
	"runtime"
	"github.com/owenliang/cronta
    
func main() {
	var (
		err error
	)

	// 初始化命令行参数
	initArgs()

	// 初始化线程
	initEnv()

	// 加载配置
	if err = master.InitConfig(confFile); err != nil {
		goto ERR
	}

	// 初始化服务发现模块
	if err = master.InitWorkerMgr(); err != nil {
		goto ERR
	}

	// 日志管理器
	if err =master.InitLogMgr(); err != nil {
		goto ERR
	}

	//  任务管理器
	if err = master.InitJobMgr(); err != nil {
		goto ERR
	}

	// 启动Api HTTP服务
	if err = master.InitApiServer(); err != nil {
		goto ERR
	}

	// 正常退出
	for {
		time.Sleep(1 * time.Second)
	}

	return

ERR:
	fmt.Println(err)
}
