Change readiness to liveness for default health check

[stephan-strate]

Is it possible to change or add liveness check to an existing readiness check?
So for example adding liveness check to DataSourceHealthCheck.

I created a "CustomHealthCheck" bean that inherits from DataSourceHealthCheck. That works just fine, but I would like to know if there is a better way to do this.

@ApplicationScoped
@Liveness
class CustomHealthCheck : DataSourceHealthCheck()

Hi @stephan-strate

you can use health registries for this but I don't think you can remove it from readiness. But you can add it to liveness like this:

@ApplicationScoped
public class StartObserver {

    @Inject
    @Readiness
    DataSourceHealthCheck healthCheck;

    public void observeStart(@Observes StartupEvent startupEvent) {
        HealthRegistries.getRegistry(HealthType.LIVENESS).register(healthCheck);
    }
}

Thanks, that works! You might be able to use HealthRegistries.getRegistry(HealthType.READINESS).remove(healthCheck) to remove the health check from readiness, but I did not try it. I am totally fine with having it as readiness and liveness check.

Unfortunately no, registries are a separate registration mechanism, so only HC registered through registry can be removed. But you can disable this check with config (don't know on top my head) but then it will probably won't work as above since that reuses the implementation :)
