前言
生态系统
总体来说，我们现在所处的时代仍是
Kubernetes
生态的早期。
2018
年初，
Kubernetes
逐渐成为容器（及其生命周期）管理领域的工业标准，但是仍然
缺少一些基于实践经验的指导去指引开发者编写原生
Kubernetes
应用。虽然
一些基本的组件，比如
client-go
、自定义资源（
Custom Resource
）和云原生
编程语言都已经出现了，但是相关的知识仍然十分零碎，它们存在于人们的
经验中，分散在各种
Slack
频道和
StackOverflow
的回答中。
本书写作之时，
Kubernetes
的最新版本是
1.15
。书中例子的代码是基于
1.14
的库来编写的，编译后应该可以在低版本（但不低于
1.12
）的
Kubernetes
上
运行。部分
CRD
相关的高级功能需要
1.13
或
1.14
版本的
Kubernetes
才能
正常运行，第
9
章介绍的“
CRD
转换”在
1.15
版本的
Kubernetes
上才能运行。
如果你没有足够新的集群用于测试，我们强烈推荐你在本地运行
Minikube
或
kind
来进行测试。
你需要了解的技术
本书是一本中等难度的技术书籍，阅读本书需要理解很多开发和系统管理的
概念。在深入具体内容之前，你需要先复习以下知识。
包管理
本书中用到工具常常需要你安装一些软件包才能满足其依赖。了解你所使
用的操作系统中的包管理模式是必备的技能。比如
Ubuntu/Debian
系统中
的
apt
、
CentOS/RHEL
系统中的
yum
、
macOS
上的
port
或
brew
。不管是
哪一种，你都需要了解如何使用它们对软件包进行安装、 ...
