preoomkiller-controller

preoomkiller-controller monitors memory usage metrics for all pods matching label selector preoomkiller-enabled=true, and when memory usage for pods go above a threshold, specified in pod annotation preoomkiller.alpha.k8s.zapier.com/memory-threshold, it attempts to evict the pods. This is a very safe operation as eviction takes into account PodDisruptionBudget and allows for a graceful termination of the pods.
