Go Programming Pattern in Kubernetes Philosophy Harry Zhang @resouer Contents • What I will talk? • Kubernetes basic in 1 min • For Kubernetes developers: • The Golang programming patterns of interface design in Kubernetes (CRI as example) • For Kubernetes users: • Effective pattern of programming based on Kubernetes • ⼴广告（Don’t worry, it’s not that kind of AD） • What I will not talk? • https://github.com/google/lmctfy • Now think about a C/C++ based Kubernetes? • And, well designed programming patterns with powerful extensibility Understand Kubernetes in 1 min Container Pod Deployment

• Declarative system • Manage resource to final state continually • kube-apiserver oriented programming • CustomResourceDefinition (CRD) • Built on Kubernetes APIs • Kubernetes repo support • Agile

a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies. " (Martin Fowler) 什么是微服务架构? 单体 – 微服务

力。不同重复造轮子只是适 配不同 API 如何基于 K8s ，构建出一个既用户友好，又高可扩展，还 统一、标准化的应用管理平台？ 简单的“客户端”抽象： DCL (Data Configuration Language) 对 K8s 资源进行抽象实际上就是在操纵 YAML 数据，通过 DCL 来完成相比于 CRD + controller 更简单 CUE • 功能强大：专注于操纵数据，而不是写 代码 •
