Kubernetes brought an excellent deployment platform to work on. Even monolithic applications can be run in a container. For some of these monolithic applications and for some microservices, a slow start is a problem. Even if we configure readiness and liveness probes using initialDelaySeconds, this is not an ideal way to do this. For this specific problem, startup probes are developed.
