Probably healthcheck[0]? And Kubernetes have a similar concept called probes[1]. These basically allow to define a custom action(s) to check whether service is healthy (in addition to the default "is PID still alive"). If it is deemed not healthy, usually the action is to automatically restart it. 0: https://docs.docker.com/reference/compose-file/services/#healthcheck 1: https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/ Tomas -- There are only two hard things in Computer Science: cache invalidation, naming things and off-by-one errors.
