<p class="p_Normal">Kubernetes is one of the most popular tools for managing containerized applications in modern development environments. In this article, you can find a step-by-step guide for installing and configuring Kubernetes using kubeadm.</p>
<p class="p_Normal">The main components of Kubernetes are:</p>
<p class="p_Normal">Kubernetes — один из самых популярных инструментов для управления контейнеризированными приложениями в современных средах разработки. В этой статье рассмотрим шаги по установке и настройке Kubernetes с использованием kubeadm.</p>
<p class="p_Normal">Основные компоненты Kubernetes:</p>
<ul style="list-style-type:disc">
<li class="p_Normal">A master node. It is a node that manages the entire cluster. It monitors other nodes and distributes the load using the controller manager and scheduler. To increase fault tolerance, we recommend having several master nodes.</li><li class="p_Normal">Worker nodes. These are nodes for launching containers. The more worker nodes you have, the more applications you can run. The number of nodes also affects the fault tolerance of the cluster. When one node fails, the load is redistributed to others.</li></ul>
<p class="p_Normal">Below, you can find how to deploy a standard Kubernetes cluster that consists of a master node and a worker node.</p>
<li class="p_Normal">мастер-нода (master) — узел, управляющий всем кластером. Он отслеживает другие узлы и распределяет нагрузку с помощью менеджера контроллеров и планировщика. Для повышения отказоустойчивости рекомендуем иметь несколько мастер-нод;</li><li class="p_Normal">рабочие узлы (worker) — узлы, на которых запускаются контейнеры. Чем больше рабочих узлов, тем больше приложений можно запустить. Количество узлов также влияет на отказоустойчивость кластера, так как при выходе из строя одного узла нагрузка перераспределяется на другие.</li></ul>
<p class="p_Normal">Рассмотрим, как развернуть стандартный Kubernetes-кластер, который состоит из master-узла и worker-узла.</p>

<p class="p_Normal"><span style="font-weight: bold;">Note</span></p>
<p class="p_Normal">This article helps you set up a standard Kubernetes cluster for development or testing environments. For the production environment, we recommend installing <a href="fail-safe-kubernetes-cluster.html" class="topiclink">Deckhouse</a>.</p>
<p style="margin: 14px 0 0 0;"><span style="font-weight: bold;">Примечание</span></p>
