Feature state: Stable since Kubernetes v1.24 When you run a Pod on a Node, the Pod itself takes an amount of system resources. These resources are additional to the resources needed to run the container(s) inside the Pod. In Kubernetes, Pod Overhead is a way to account for the resources consumed by
Node-pressure eviction is the process by which the kubelet proactively terminates pods to reclaim resource on nodes. The kubelet monitors resources like memory, disk space, and filesystem inodes on your cluster's nodes. When one or more of these resources reach specific consumption levels, the kubel
Feature state: Stable since Kubernetes v1.37 More information about this feature This is a stable feature in Kubernetes, and has been since version v1.37. It was first available in the v1.35 release. You can no longer disable or opt out of this feature or behavior (it is locked); if you explicitly s
In Kubernetes, scheduling refers to making sure that Pods are matched to Nodes so that Kubelet can run them. Scheduling overview A scheduler watches for newly created Pods that have no Node assigned. For every Pod that the scheduler discovers, the scheduler becomes responsible for finding the best N
Feature state: Beta since Kubernetes v1.37; disabled by default More information about this feature To use this feature, you (or a cluster administrator) will need to enable the GenericWorkload feature gate for all relevant components in your cluster.

You can constrain a Pod so that it is restricted to run on particular node(s) , or to prefer to run on particular nodes. There are several ways to do this and the recommended approaches all use label selectors to facilitate the selection. Often, you do not need to set any such constraints; the sched
API-initiated eviction is the process by which you use the Eviction API to create an Eviction object that triggers graceful pod termination. You can request eviction by calling the Eviction API directly, or programmatically using a client of the API server , like the kubectl drain command. This crea
In order to support latency-critical and high-throughput workloads, Kubernetes offers a suite of Resource Managers. The managers aim to co-ordinate and optimize the alignment of node's resources for pods configured with a specific requirement for CPUs, devices, and memory (hugepages) resources. Topo
