The Kubernetes API server stores objects, relying on an etcd-compatible backing store (often, the backing storage is etcd itself). Each object is serialized using a particular version of that API type; for example, the v1 representation of a ConfigMap. Kubernetes uses the term storage version to des
The kubectl command-line tool supports several different ways to create and manage Kubernetes objects . This document provides an overview of the different approaches. Read the Kubectl book for details of managing objects by Kubectl. Management techniques Warning: A Kubernetes object should be manag
Feature state: Stable since Kubernetes v1.24 When you run a Pod on a Node, the Pod itself takes an amount of system resources. These resources are additional to the resources needed to run the container(s) inside the Pod. In Kubernetes, Pod Overhead is a way to account for the resources consumed by
Feature state: Stable since Kubernetes v1.20 This page describes the RuntimeClass resource and runtime selection mechanism. RuntimeClass is a feature for selecting the container runtime configuration. The container runtime configuration is used to run a Pod's containers. Motivation You can set a dif
This page describes device taints and tolerations in DRA, which let drivers and admins keep Pods off specific devices, or evict Pods already using them. Device taints and tolerations Feature state: Stable since Kubernetes v1.37 More information about this feature This is a stable feature in Kubernet
When you specify a Pod , you can optionally specify how much of each resource a container needs. The most common resources to specify are CPU and memory (RAM); there are others. When you specify the resource request for containers in a Pod, the kube-scheduler uses this information to decide which no
In Kubernetes, scheduling refers to making sure that Pods are matched to Nodes so that Kubelet can run them. Scheduling overview A scheduler watches for newly created Pods that have no Node assigned. For every Pod that the scheduler discovers, the scheduler becomes responsible for finding the best N
A container image represents binary data that encapsulates an application and all its software dependencies. Container images are executable software bundles that can run standalone and that make very well-defined assumptions about their runtime environment. You typically create a container image of
Kubernetes runs your workload by placing containers into Pods to run on Nodes . A node may be a virtual or physical machine, depending on the cluster. Each node is managed by the control plane and contains the services necessary to run Pods . Typically you have several nodes in a cluster; in a learn
