How do I gracefully shut down in containers in Go projects?

package main

import (
    "context"
    "fmt"
    "net/http"
    "os"
    "os/signal"
    "syscall"
    "time"
)

func main() {
    srv := &http.Server{Addr: ":8080", Handler: http.DefaultServeMux}

    // Channel to listen for interrupt signals
    stop := make(chan os.Signal, 1)
    signal.Notify(stop, syscall.SIGINT, syscall.SIGTERM)

    // Start the server in a goroutine
    go func() {
        if err := srv.ListenAndServe(); err != nil && err != http.ErrServerClosed {
            fmt.Println("ListenAndServe(): ", err)
        }
    }()

    // Wait for interrupt signal
    <-stop
    fmt.Println("Shutting down server...")

    // Create a timeout context for shutdown
    ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
    defer cancel()

    // Shutdown the server with a timeout
    if err := srv.Shutdown(ctx); err != nil {
        fmt.Println("Server forced to shutdown: ", err)
    }
    fmt.Println("Server exiting")
}
