Graceful Shutdown

Using http.Server#Shutdown()

server.go

package main
import (
    "context"
    "net/http"
    "os"
    "os/signal"
    "time"
    "github.com/labstack/echo"
    "github.com/labstack/gommon/log"
)
func main() {
    // Setup
    e := echo.New()
    e.Logger.SetLevel(log.INFO)
    e.GET("/", func(c echo.Context) error {
        time.Sleep(5 * time.Second)
        return c.JSON(http.StatusOK, "OK")
    })
    // Start server
    go func() {
        if err := e.Start(":1323"); err != nil {
            e.Logger.Info("shutting down the server")
        }
    }()
    // Wait for interrupt signal to gracefully shutdown the server with
    // a timeout of 10 seconds.
    quit := make(chan os.Signal)
    signal.Notify(quit, os.Interrupt)
    <-quit
    ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
    defer cancel()
    if err := e.Shutdown(ctx); err != nil {
        e.Logger.Fatal(err)
    }
}

Requires go1.8+

    })
    e.Server.Addr = ":1323"
    // Serve it like a boss
    e.Logger.Fatal(gracehttp.Serve(e.Server))
