Shutdown
Wait for servers to terminate gracefully.
Example:
import (
"context"
"log"
"net/http"
"time"
"github.com/bsm/shutdown"
)
func main() {
srv := &http.Server{
Addr: ":8080",
Handler: http.FileServer(http.Dir("/usr/share/doc")),
}
// Wait for either SIGINT/SIGTERM or ListenAndServe to exit.
// Handle errors.
err := shutdown.Wait(srv.ListenAndServe)
if err != nil && err != http.ErrServerClosed {
log.Fatalln("Server error", err)
}
// Perform a graceful server shutdown.
log.Println("Shutting down ...")
timeoutCtx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()
if err := srv.Shutdown(timeoutCtx); err != nil {
log.Println("Shutdown error", err)
}
}
