Node Problem Detector is a daemon for monitoring and reporting about a node's health. You can run Node Problem Detector as a DaemonSet or as a standalone daemon. Node Problem Detector collects information about node problems from various daemons and reports these conditions to the API server as Node Conditions or as Events. To learn how to install and use Node Problem Detector, see Node Problem Detector project documentation.

FEATURE STATE: Kubernetes v1.31 [beta] (enabled by default: false) This document shares how to extend the existing Service IP range assigned to a cluster. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts.

Synopsis kubectl controls the Kubernetes cluster manager. Find more information at: https://kubernetes.io/docs/reference/kubectl/ kubectl [flags] Options --as string Username to impersonate for the operation. User could be a regular user or a service account in a namespace. --as-group strings Group to impersonate for the operation, this flag can be repeated to specify multiple groups. --as-uid string UID to impersonate for the operation. --cache-dir string     Default: "$HOME/.kube/cache" Default cache directory --certificate-authority string Path to a cert file for the certificate authority

Synopsis Edit the latest last-applied-configuration annotations of resources from the default editor. The edit-last-applied command allows you to directly edit any API resource you can retrieve via the command-line tools. It will open the editor defined by your KUBE_EDITOR, or EDITOR environment variables, or fall back to 'vi' for Linux or 'notepad' for Windows. You can edit multiple objects, although changes are applied one at a time. The command accepts file names as well as command-line arguments, although the files you point to must be previously saved versions of resources.

This document shares how to validate IPv4/IPv6 dual-stack enabled Kubernetes clusters. Before you begin Provider support for dual-stack networking (Cloud provider or otherwise must be able to provide Kubernetes nodes with routable IPv4/IPv6 network interfaces) A network plugin that supports dual-stack networking. Dual-stack enabled cluster Your Kubernetes server must be at or later than version v1.23. To check the version, enter kubectl version. Note:While you can validate with an earlier version, the feature is only GA and officially supported since v1.

This section of the Kubernetes documentation contains tutorials. A tutorial shows how to accomplish a goal that is larger than a single task. Typically a tutorial has several sections, each of which has a sequence of steps. Before walking through each tutorial, you may want to bookmark the Standardized Glossary page for later references. Basics Kubernetes Basics is an in-depth interactive tutorial that helps you understand the Kubernetes system and try out some basic Kubernetes features.
