If you want to learn how to get started managing and operating a Kubernetes cluster, this page and the linked topics introduce you to the foundational concepts and tasks.
|
||||
This page introduces you to a Kubernetes cluster and key concepts to understand and manage it. The content focuses primarily on the cluster itself rather than the software running within the cluster.
|
||||
-->
|
||||
如果您想学习如何开始管理和操作 Kubernetes 集群，本页面和链接主题将向您介绍基础概念和任务。本页面向您介绍 Kubernetes 集群以及理解和管理它的关键概念。内容主要关注集群本身，而不是集群中运行的软件。

## Kubernetes 概要
|
||||
|
||||
<!--
|
||||
If you have not already done so, start your understanding by reading through [What is Kubernetes?](/docs/concepts/overview/what-is-kubernetes/), which introduces a number of basic concepts and terms.
|
||||
-->
|
||||
如果你还没有这样做，请通过阅读[什么是 Kubernetes?](/docs/concepts/overview/what-is-kubernetes/)开始理解，其中介绍了许多基本概念和术语。
|
||||
|
||||
<!--
|
||||
Kubernetes is quite flexible, and a cluster can be run in a wide variety of places. You can interact with Kubernetes entirely on your own laptop or local development machine with it running within a virtual machine. Kubernetes can also run on virtual machines hosted either locally or in a cloud provider, and you can run a Kubernetes cluster on bare metal.
|
||||
-->
|
||||
Kubernetes 非常灵活，集群可以在各种各样的地方运行。您可以在自己的笔记本电脑或本地开发机器上完全与 Kubernetes 交互，并在虚拟机中运行。Kubernetes 还可以在本地或云提供商托管的虚拟机上运行，并且您也可以在裸机上运行 Kubernetes 集群。
|
||||
|
||||
<!--
|
||||
A cluster is made up of one or more [Nodes](/docs/concepts/architecture/nodes/); where a node is a physical or virtual machine.
|
||||
If there is more than one node in your cluster then the nodes are connected with a [cluster network](/docs/concepts/cluster-administration/networking/).
|
||||
Regardless of how many nodes, all Kubernetes clusters generally have the same components, which are described in [Kubernetes Components](/docs/concepts/overview/components).
|
||||
-->
|
||||
集群由一个或多个[节点](/docs/concepts/architecture/nodes/)组成；节点是物理机或虚拟机的位置。
|
||||
如果集群中有多个节点，则节点将与[集群网络](/docs/concepts/cluster-administration/networking/)连接。
|
||||
无论有多少个节点，所有 Kubernetes 集群通常具有相同的组件，这些组件在[Kubernetes 组件](/docs/concepts/overview/components)中有所描述。

|
||||
A good way to become familiar with how to manage and operate a Kubernetes cluster is by setting one up.
|
||||
One of the most compact ways to experiment with a cluster is [Installing and using Minikube](/docs/tasks/tools/install-minikube/).
|
||||
Minikube is a command line tool for setting up and running a single-node cluster within a virtual machine on your local laptop or development computer. Minikube is even available through your browser at the [Katacoda Kubernetes Playground](https://www.katacoda.com/courses/kubernetes/playground).
|
||||
Katacoda provides a browser-based connection to a single-node cluster, using minikube behind the scenes, to support a number of tutorials to explore Kubernetes. You can also leverage the web-based [Play with Kubernetes](http://labs.play-with-k8s.com/) to the same ends - a temporary cluster to play with on the web.
|
||||
-->
|
||||
一个熟悉如果管理和操作 Kubernetes 集群的好方法就是设置一个。
|
||||
实验集群最紧凑的方法之一是[安装和使用 Minikube](/docs/tasks/tools/install-minikube/)。
|
||||
Minikube 是一个命令行工具，用于在笔记本电脑或开发计算机上的虚拟机中设置和运行单节点集群。甚至可以通过[Katacoda Kubernetes Playground](https://www.katacoda.com/courses/kubernetes/playground)的浏览器获取 Minikube。
|
||||
Katacoda 提供一个基于浏览器的连接到单节点集群，在幕后使用 minikube，支持一些教程来探索 Kubernetes。您还可以利用基于网络的[Play with Kubernetes](http://labs.play-with-k8s.com/)来实现相同目的——在网络上使用的临时集群。
|
||||
|
||||
<!--
|
||||
You interact with Kubernetes either through a dashboard, an API, or using a command-line tool (such as `kubectl`) that interacts with the Kubernetes API.
|
||||
Be familiar with [Organizing Cluster Access](/docs/concepts/configuration/organize-cluster-access-kubeconfig/) by using configuration files.
|
||||
The Kubernetes API exposes a number of resources that provide the building blocks and abstractions that are used to run software on Kubernetes.
|
||||
Learn more about these resources at [Understanding Kubernetes Objects](/docs/concepts/overview/working-with-objects/kubernetes-objects).
|
||||
These resources are covered in a number of articles within the Kubernetes documentation.
|
||||
-->
|
||||
您可以通过 dashboard，API 或者使用命令行工具（例如`kubectl`）与 Kubernetes API 进行交互。
|
||||
通过使用配置文件熟悉[组织群集访问](/docs/concepts/configuration/organize-cluster-access-kubeconfig/) 。
|
||||
Kubernetes API 公开了许多资源，这些资源提供了在 Kubernetes 上运行软件的构建块和抽象。
|
||||
在[Understanding Kubernetes Objects](/docs/concepts/overview/working-with-objects/kubernetes-objects)中了解有关这些资源的更多信息。
|
||||
Kubernetes 文档中的许多文章都涵盖了这些资源。

As a cluster operator you may not need to use all these resources, although you should be familiar with them to understand how the cluster is being used.
|
||||
There are a number of additional resources that you should be aware of, some listed under [Intermediate Resources](/docs/user-journeys/users/cluster-operator/intermediate#section-1).
|
||||
You should also be familiar with [how to manage kubernetes resources](/docs/concepts/cluster-administration/manage-deployment/)
|
||||
and [supported versions and version skew between cluster components](/docs/setup/release/version-skew-policy/).
|
||||
-->
|
||||
作为集群运算符，您可能不需要使用所有这些资源，尽管您应该熟悉它们以了解集群的使用方式。
|
||||
您应该了解许多其他资源，其中一些列在[中间资源](/docs/user-journeys/users/cluster-operator/intermediate#section-1)下。
|
||||
您还应该熟悉[如何管理 kubernetes 资源](/docs/concepts/cluster-administration/manage-deployment/)
|
||||
和[支持的版本和集群组件之间的版本偏差](/docs/setup/release/version-skew-policy/)。

You can [access clusters using the Kubernetes API](/docs/tasks/administer-cluster/access-cluster-api/).
|
||||
If you are not already familiar with how to do this, you can review the [introductory tutorial](/docs/tutorials/kubernetes-basics/explore-intro/).
|
||||
Using `kubectl`, you can retrieve information about your Kubernetes cluster very quickly.
|
||||
To get basic information about the nodes in your cluster run the command `kubectl get nodes`.
|
||||
You can get more detailed information for the same nodes with the command `kubectl describe nodes`.
|
||||
You can see the status of the core of kubernetes with the command `kubectl get componentstatuses`.
|
||||
-->
|
||||
您可以[使用 Kubernetes API 访问集群](/docs/tasks/administer-cluster/access-cluster-api/)。
|
||||
如果您还不熟悉如何执行此操作，可以查看[入门教程](/docs/tutorials/kubernetes-basics/explore-intro/)。
|
||||
使用`kubectl`，您可以快速检索有关 Kubernetes 集群的信息。
|
||||
要获取有关集群中节点的基本信息，请运行命令`kubectl get nodes`。
|
||||
您可以使用命令`kubectl describe nodes`获取相同节点的更多详细信息。
|
||||
您可以使用命令`kubectl get componentstatuses`查看 kubernetes 的核心状态。
