This page explains proxies used with Kubernetes. Proxies There are several different proxies you may encounter when using Kubernetes: The kubectl proxy : runs on a user's desktop or in a pod proxies from a localhost address to the Kubernetes apiserver client to proxy uses HTTP proxy to apiserver use
Automatically provision and consolidate the Nodes in your cluster to adapt to demand and optimize cost. In order to run workloads in your cluster, you need Nodes . Nodes in your cluster can be autoscaled - dynamically provisioned , or consolidated to provide needed capacity while optimizing cost. Au
This page describes the Kubernetes API kinds that dynamic resource allocation (DRA) uses to categorize, request, and allocate devices. DRA terminology DRA uses the following Kubernetes API kinds to provide the core allocation functionality. All of these API kinds are included in the resource.k8s.io/
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.
