advancedSpring Boot on Kubernetes: Health Probes, Config, Scaling & Observability
How does server.shutdown: graceful work in Kubernetes?
When Kubernetes sends SIGTERM, Spring Boot stops accepting new HTTP requests but continues processing in-flight requests until they complete or spring.lifecycle.timeout-per-shutdown-phase is reached. Kubernetes's terminationGracePeriodSeconds must be longer than the graceful shutdown timeout, otherwise SIGKILL arrives and cuts off in-flight requests.
