启动服务是可以指定app name和port。

package main

import (
	"fmt"
	"net/http"

	"github.com/labstack/echo"
	"gopkg.in/alecthomas/kingpin.v2"
)

var (
	argAppName = kingpin.Arg("name", "Application name").Required().String()
	argPort    = kingpin.Arg("port", "Web server port").Default("9000").Int()
)

func main() {
	kingpin.Parse()

	appName := *argAppName
	port := fmt.Sprintf(":%d", *argPort)

	fmt.Printf("Starting %s at %s", appName, port)

	e := echo.New()
	e.GET("/index", func(c echo.Context) (err error) {
		return c.JSON(http.StatusOK, true)
	})
	e.Logger.Fatal(e.Start(port))
}

编译后执行

 ./main "Echo Demo part 8" 3000
