A StatefulSet runs a group of Pods, and maintains a sticky identity for each of those Pods. This is useful for managing applications that need persistent storage or a stable, unique network identity.

Ways to provide both long-term and temporary storage to Pods in your cluster.

Before you begin You must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.33 client can communicate with v1.32, v1.33, and v1.34 control planes. Using the latest compatible version of kubectl helps avoid unforeseen issues. Install kubectl on Linux The following methods exist for installing kubectl on Linux: Install kubectl binary with curl on Linux Install using native package management Install using other package management Install kubectl binary with curl on Linux Download the latest release with the command:

FEATURE STATE: Kubernetes v1.18 [beta] This page explains how to upgrade a Windows node created with kubeadm. Before you begin You need to have shell access to all the nodes, 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. Your Kubernetes server must be at or later than version 1.

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 uses HTTPS locates apiserver adds authentication headers The apiserver proxy: is a bastion built into the apiserver connects a user outside of the cluster to cluster IPs which otherwise might not be reachable runs in the apiserver processes client to proxy uses HTTPS (or http if apiserver so configured) proxy to target may use HTTP or HTTPS as chosen by proxy using available information can be used to reach a Node, Pod, or Service does load balancing when used to reach a Service The kube proxy:

This page shows how to change the default Storage Class that is used to provision volumes for PersistentVolumeClaims that have no special requirements. 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:

Define overall memory and CPU resource limits for a namespace.
