of Kubernetes (Controller, codegen etc) • Write your own Controller • gPRC based interface design in Kubernetes (CRI as example) • For Kubernetes users: • Effective pattern of programming based management project created by Google • Successor of Google Borg/Omega system • One of the most popular open source projects in this world • Written by, and heavily depends on Golang Again: Why Go? • All --token $token ${master_ip:port} • Done! But that’s only one part … • Kubernetes is also about design pattern in container world • decoupling containers • re-use images • well-designed architecture

与开发⼈员和⽤户可⽤的API相同。⽤户可以使⽤ their own API 编写⾃⼰ 的控制器，例如 scheduler ，这些API可由通⽤ command-line tool 定位。 这种 design 使得许多其他系统可以构建在Kubernetes上。 Kubernetes不是什么？ Kubernetes不是⼀个传统的，全⾯的PaaS系统。 它保留了⽤户的重要选择。 Kubernetes： 使⽤v1.2规范。OpenAPI规范在Kubernetes 1.5中，进⼊Beta 阶段。 Kubernetes为主要⽤于集群内通信的API实现了另⼀种基于Protobuf的序列化格式，在 design proposal 有记录，每个 schema的IDL⽂件都存放在定义该API对象的Go语⾔包中。 API版本 为了更容易地消除字段或重组资源表示，Kubernetes⽀持多种API版本，每种API版本都有不同的API路径，例 。按照惯例，Kubernetes资源的名称最多可达253个字符，由⼩写字⺟、数字、 - 和 . 组 成，但某些资源有更具体的限制。有关名称的精确语法规则，详⻅： identifiers design doc 。 UID UID由Kubernetes⽣成。 在Kubernetes集群的整个⽣命周期中创建的每个对象都有不同的UID（即：它们在空间和时间 上是唯⼀的）。 07-Name
