This page explains how to add versioning information to CustomResourceDefinitions, to indicate the stability level of your CustomResourceDefinitions or advance your API to a new version with conversion between API representations. It also describes how to upgrade an object from one version to another. 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.

Configure and manage huge pages as a schedulable resource in a cluster.

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

This task shows how to scale a StatefulSet. Scaling a StatefulSet refers to increasing or decreasing the number of replicas. Before you begin StatefulSets are only available in Kubernetes version 1.5 or later. To check your version of Kubernetes, run kubectl version. Not all stateful applications scale nicely. If you are unsure about whether to scale your StatefulSets, see StatefulSet concepts or StatefulSet tutorial for further information. You should perform scaling only when you are confident that your stateful application cluster is completely healthy.

Kubernetes namespaces help different projects, teams, or customers to share a Kubernetes cluster. It does this by providing the following: A scope for Names. A mechanism to attach authorization and policy to a subsection of the cluster. Use of multiple namespaces is optional. This example demonstrates how to use Kubernetes namespaces to subdivide your 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.

This page shows how to enable and configure certificate rotation for the kubelet. FEATURE STATE: Kubernetes v1.19 [stable] Before you begin Kubernetes version 1.8.0 or later is required Overview The kubelet uses certificates for authenticating to the Kubernetes API. By default, these certificates are issued with one year expiration so that they do not need to be renewed too frequently. Kubernetes contains kubelet certificate rotation, that will automatically generate a new key and request a new certificate from the Kubernetes API as the current certificate approaches expiration.

Production-Grade Container Orchestration

FEATURE STATE: Kubernetes v1.19 [stable] Seccomp stands for secure computing mode and has been a feature of the Linux kernel since version 2.6.12. It can be used to sandbox the privileges of a process, restricting the calls it is able to make from userspace into the kernel. Kubernetes lets you automatically apply seccomp profiles loaded onto a node to your Pods and containers. Identifying the privileges required for your workloads can be difficult.

FEATURE STATE: Kubernetes v1.33 [stable](enabled by default) 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. If you do not already have a cluster, you can create one by using minikube or you can use one of these Kubernetes playgrounds:
