Açıklaması şöyle

Kubernetes has built-in probes for determining whether or not a Pod is alive and ready to serve incoming requests. This is known as the Health Check pattern, which is is supported in Quarkus using the SmallRye Health extension. The SmallRye Health extension is an implementation of the MicroProfile Health specification. 

Spring Boot applications can use the Kubernetes probes included in the Spring Boot Actuator starter; however, the Spring Boot Actuator only provides the endpoints and doesn't generate the necessary configuration or the required Kubernetes manifests. They will need to be created manually.
