Get the event when quarkus.shutdown.delay begins

[danieltche]

Hi everyone.

Is it possible to get the event when the quarkus.shutdown.delay countdown starts? In a Kubernetes environment, I noticed the sequence is:

• quarkus.shutdown.delay time;
• @observes ShutdownEvent
• @PreDestroy

I´m working with a Scheduler and I want to wait about 30 seconds after the shutdown event starts.

I assume you mean a CDI event? If so, then no, we don't fire a CDI event during the preShutdown phase.

However, it might be a good idea to fire a PreShutdown synchronously, i.e. register a io.quarkus.runtime.shutdown.ShutdownListener with a ShutdownListenerBuildItem.

@manovotn @Ladicek WDYT?

Agree we should fire some kind of a PreShutdown event.

I agree that having some observable event when the countdown starts seems useful.
We could even reuse ShutdownEvent with proper payload and a qualifier perhaps?

As a side note, when/if we do that, we should also document it here.

I've created #49752 to track this

This has now been implemented under #49752, closing this discussion.
