Synopsis The Kubernetes API server validates and configures data for the api objects which include pods, services, replicationcontrollers, and others. The API Server services REST operations and provides the frontend to the cluster's shared state through which all other components interact. kube-apiserver [flags] Options --admission-control-config-file string File with admission control configuration. --advertise-address string The IP address on which to advertise the apiserver to members of ...| Kubernetes
Synopsis The kubelet is the primary "node agent" that runs on each node. It can register the node with the apiserver using one of: the hostname; a flag to override the hostname; or specific logic for a cloud provider. The kubelet works in terms of a PodSpec. A PodSpec is a YAML or JSON object that describes a pod. The kubelet takes a set of PodSpecs that are provided through various mechanisms (primarily through the apiserver) and ensures that the containers described in those PodSpecs are ru...| Kubernetes
Synopsis The Kubernetes controller manager is a daemon that embeds the core control loops shipped with Kubernetes. In applications of robotics and automation, a control loop is a non-terminating loop that regulates the state of the system. In Kubernetes, a controller is a control loop that watches the shared state of the cluster through the apiserver and makes changes attempting to move the current state towards the desired state. Examples of controllers that ship with Kubernetes today are th...| Kubernetes
The v1.29 release of Kubernetes introduced an alpha feature to support modifying a volume by changing the volumeAttributesClassName that was specified for a PersistentVolumeClaim (PVC). With the feature enabled, Kubernetes can handle updates of volume attributes other than capacity. Allowing volume attributes to be changed without managing it through different provider's APIs directly simplifies the current flow. You can read about VolumeAttributesClass usage details in the Kubernetes documen...| Kubernetes

This page contains an overview of the various feature gates an administrator can specify on different Kubernetes components. See feature stages for an explanation of the stages for a feature. Overview Feature gates are a set of key=value pairs that describe Kubernetes features. You can turn these features on or off using the --feature-gates command line flag on each Kubernetes component. Each Kubernetes component lets you enable or disable a set of feature gates that are relevant to that comp...| Kubernetes
