scala - How to stop gracefully the actor system for an akka-http server that must be deployed.

I just created my first rest server with akka-http. The problem is that I do not know how to deploy the server in such a way that I could gracefully shutdown the actor system.

For example I found something here: https://stackoverflow.com/a/17399574/5388513 where you could use Akka's microkernel, but it is deprecated. I tried using sbt-native-package, but I do not know how to gracefully shutdown the actor system.

Thank you!

You can add shutdown hook:

// import scala.concurrent.duration._
//shutdown Hook
scala.sys.addShutdownHook {
  logger.info("Terminating...")
  actorSystem.terminate()
  Await.result(actorSystem.whenTerminated, 30 seconds)
  logger.info("Terminated... Bye")
}
