Using SIGINT to gracefully shut down a service

signals.go

package main

import (
    "fmt"
    "os"
    "os/signal"
    "time"
)

func main() {
    ch := make(chan os.Signal, 1)
    signal.Notify(ch, os.Interrupt)
    sig := <-ch
    fmt.Println("Recieved signal:", sig)
    fmt.Println("Shutting down...")
    time.Sleep(3 * time.Second)
    fmt.Println("Shutdown complete")
}
