docker pull etcd
docker run -d --name echo_etcd -p 2379:2379 etcd  

# set some example k/v paramters
docker exec -it echo_etcd /bin/sh

$ go get -u github.com/Wang-Kai/echo

go test -v -run=GetConf

import (

var AppConf echo.Config

const (
   etcdURI        = "http://127.0.0.1:2379"
   configParamDir = "my_config/"
)

// load config paramters
func init() {
   echoAgent, err := echo.New(etcdURI)
   if err != nil {
   	log.Fatal(err)
   }

   config, err := echoAgent.GetConf(configParamDir)
   if err != nil {
   	log.Fatal(err)
   }
   
   // export global configuration
   AppConf = config

   // use your config any where
   //  ...
}
