概论
“
Kubernetes
编程”这个词对于不同的人有着不同的含义。在本章中，我们
首先定义本书的内容和关注点。同时，我们还会介绍学习过程中所需要的测
试环境，以及你要完成的准备工作。有了这些基本的环境来帮助学习，你才
能从本书中获得最大的收益。我们还将介绍什么是
Kubernetes
编程、什么
是原生
Kubernetes
应用，并通过一个实际的例子来介绍它们所具备的基本
特征。我们会介绍有关控制器和
Operator
的基本概念，以及基于事件驱动的
Kubernetes
控制平面的工作原理。准备好了吗？让我们开始吧！
1.1
什么是
Kubernetes
编程？
我们假设你可以访问一个可用的
Kubernetes
集群，比如
Amazon EKS
、
Microsoft AKS
、
Google GKE
或者
OpenShift
所提供的类似环境。
大部分情况下，你都可以在你的笔记本电脑或台式机本地完成开发工作，也
就是说，开发时所使用的
Kubernetes
环境是运行在本地，而不是运行在云端
或是数据中心。若要进行本地开发，也有多种方式。基于不同的操作系统和
个人爱好，你可以在下列方案中灵活选择：
kind
、
k3d
和
Docker Desktop
