Is there any recommended way to gracefully shutdown a Spring:boot 2 app in Kubernetes.

1. Catch a termination signal SIGTERM
2. Tell Tomcat to stop taking new requests. (or Jetty, Undertow or Netty/WebFlux depending on the embedded web server used). Or tell SCS to stop sending/listening for messages on Kafka.
3. Tell Actuator health endpoint to go SERVICE_UNAVAILABLE (503)
4. And then after a X seconds shutdown the application or (SIGKILL)

I'm trying to do a graceful shutdown Rest apps and SCS (kafka consumer&producer) apps
