Kubernetes Tutorial
Kubernetes is a tool that helps us to run and manage applications in containers. It was developed by Google Lab in 2014, and it is also known as k8s. It is an open-source container orchestration platform that automates the deployment, management, and scaling of container-based applications in different kinds of environments like physical, virtual, and cloud-native computing foundations. Containers are isolated from each other so that multiple containers can run on the same machine without interrupting anyone else. It allows us to deploy and manage container-based applications across a Kubernetes cluster of machines.
Kubernetes是一个帮助我们运行应用和管理运行在容器中的应用的一个工具，它是Google在2014年开发的，它有被称为k8s。他是一个开源的容器编排平台，它可以在物理环境或者虚拟环境，云原生计算环境环境中，自动化基于容器的应用程序的部署，管理和扩展。容器之间是相互隔离的，所以很多容器可以运行在同一台设备上，而不会彼此干扰。这就允许我们在Kubernetes集群设备上部署和管理基于容器的应用。
In this Kubernetes Tutorial you’ll learn all the basics to advanced concepts like Kubernetes service, Kubernetes cluster construction, Kubernetes deployment, Kubernetes Architecture, etc. This tutorial will provide all the essential information needed to understand and work with Kubernetes, including the use of APIs, installation, and Kubernetes cluster construction. Whether you are a beginner or an expert, this tutorial will cover all the necessary details to help you learn and understand Kubernetes.
在这个Kubernetes课程中，你可以高级概念的基础知识，比如Kubernetes 服务，Kubernetes 集群搭建，Kuberentes 调度器，Kubernetes 机构等。这个课程将提供理解和实用 Kubernetes工作的理解基础信息 ，包括使用的API接口信息，安装，和集群的搭建，不论你是新手小白还是专家，这个课程将包含所有你需要的细节，帮助你学习和理解Kubernetes。
Why do we need Kubernetes?
There are several reasons to learn Kubernetes like easy scaling of applications, self-healing, portability, and automation. It is very helpful for running microservices and distributed systems.
为什么我们需要Kubernetes？
以下几个学习Kubernetes原因比如：应用易扩展，自愈能力，轻量级，自动化，对微服务和分布式系统非常有帮助。
For example: You have a couple of applications to deploy so, you can package it into a container and run it on a server containing a Docker engine or any other container engine. You package the application into a container using a Docker file and host it on a port for the external world to access it.
But there is a drawback is that it is only running on a single server so, if at that point any failure occurs it becomes an application failure, to handle the single point of failure google introduced Kubernetes to scale applications.
举例：你有几个应用需要部署，你可以打包成镜像，可以在Docker引擎中运行，或者其他的容器引擎。你可以使用DOcker file 打包一个应用到一个容器中，映射一个端口供外接访问。
但是有个缺点，单独运行在一台服务器上，如果这个端口发生古战个，这就导致应用报错，为了处理单点故障，谷歌引入Kubernetes 来扩展应用程序。
Features of Kubernetes
- Consistent Development, management, and deployment
