Reading: Golang在Kubernetes语境下的编程范式

video: http://www.itdks.com/dakalive/detail/4020

1. Kubernetes项目为什么选择Golang？

2. Kubernetes的设计模式？

  1. controller: Level driven ,not edge driver(event driven)
  2. 「这样的Controller就是Kubernetes设计得最核心的点，无论是Kubernetes还是Scheduller，还是Controller Manager，它们可以全部简单看或简单或复杂的Controller」

这样的机制，一方面简化架构，另一方面系统通过用户自己写 controller 扩展 kubernetes 的能力

编程范式

1. Controller

2. Code generator

client-gen: generate typed kubernetes API client for type conversion-gen: seamless upgrades between API versions deepcopy-gen: deepcopy defaultrer-gen: set default values for fields go-to-protobuf: generate protobuf messag for yoour types informer-gen: generate informers that can be used to watch for updates to your types openapi-gen: generate openapi compatible API documentation
