Feature state: Beta since Kubernetes v1.36; enabled by default Kubernetes 1.37 includes a beta feature that lets an API Server proxy resource requests to other peer API servers. It also lets clients get a holistic view of resources served across the entire cluster through discovery. This is useful w
In a Kubernetes cluster, a node can be shut down in a planned graceful way or unexpectedly because of reasons such as a power outage or something else external. A node shutdown could lead to workload failure if the node is not drained before the shutdown. A node shutdown can be either graceful or no
Understand how to gain end-to-end visibility of a Kubernetes cluster through the collection of metrics, logs, and traces. In Kubernetes, observability is the process of collecting and analyzing metrics, logs, and traces—often referred to as the three pillars of observability—in order to obtain a bet
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 PodLevelResourceManagers feature gate for all relevant components in your cluster.

This page describes how to observe the status and health of resources that are dynamically allocated with DRA. Observability of dynamic resources You can check the status of dynamically allocated resources by using any of the following methods: kubelet device metrics ResourceClaim status Device heal
Feature state: Stable since Kubernetes v1.20 Kubernetes allow you to limit the number of process IDs (PIDs) that a Pod can use. You can also reserve a number of allocatable PIDs for each node for use by the operating system and daemons (rather than by Pods). Process IDs (PIDs) are a fundamental reso
This page describes good practices when configuring a Kubernetes cluster utilizing Dynamic Resource Allocation (DRA). These instructions are for cluster administrators. Separate permissions to DRA related APIs DRA is orchestrated through a number of different APIs. Use authorization tools (like RBAC
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
Distributed systems often have a need for leases , which provide a mechanism to lock shared resources and coordinate activity between members of a set. In Kubernetes, the lease concept is represented by Lease objects in the coordination.k8s.io API Group , which are used for system-critical capabilit
