Rook operator kit
这是一个用于实现
Operator
的公共库。它起源于
Rook Operator
，但是发
展成了一个独立的项目。
ericchiang/k8s
这是
Eric Chiang
基于
Kubernetes Protocol Buffers
协议生成的精简的
Go
客户端。它的行为基本和
Kubernetes
官方的
client-go
客户端一致，只需
要额外引入两个依赖。尽管它还存在一些小缺陷（例如处理集群的设置还
存在一些问题），它仍是一个简单易用的
Go
语言的包。
kutil
AppsCode
通过
kutil
工具为
Kubernetes
提供了
client-go
的插件。
基于命令行客户端的方式
如果是为了实验或测试，也可以通过调用
kubectl
来进行基于客户端的编
程（例如
kubecuddler
库）。
尽管本书重点关注如何使用
Go
语言来开发
Operator
，但是你也可以用别的
编程语言来开发
Operator
。两个比较出名的例子是
Flant
的
Shell-operator
和
Zalando
的
Kopf
（
Kubernetes Operator Framework
），前者可以让你用美好
而古老的
Shell
脚本来编写
Operator
逻辑，后者则是一个
Python
框架和库。
正如本章开头所提到的，
Operator
领域仍处于迅速的演化当中，越来越多的
从业者以代码的形式分享他们的智慧和最佳实践，所以请持续关注最新的工
具。关注线上资源和论坛，例如
#kubernetes-operators
、
#kubebuilder ...
