go-gracedown
Package go-gracedown provides a library that makes it easy to build a HTTP server that can be shutdown gracefully (that is, without dropping any connections).
SYNOPSIS
import (
"os"
"os/signal"
"github.com/shogo82148/go-gracedown"
)
func main() {
go func() {
for {
s := <-signal_chan
if s == syscall.SIGTERM {
gracedown.Close() // trigger graceful shutdown
}
}
}()
handler := MyHTTPHandler()
gracedown.ListenAndServe(":7000", handler)
}built-in graceful shutdown support (from Go version 1.8 onward)
From Go version 1.8 onward, the HTTP Server has support for graceful shutdown. (HTTP Server Graceful Shutdown) The go-gracedown package is just a wrapper of the net/http package to maintain interface compatibility. So you should use the "net/http".Server.Shutdown method and "net/http".Server.Close method directly.
Changes
- Go version 1.7 or less: The grace.Server.Close method keeps currently-open connections.
- From Go version 1.8 onward: The grace.Server.Close method drops currently-open connections.
