用 Python 给 Kubernetes 写个控制器 主讲人： 张晋涛 个人介绍 Apache APISIX PMC Kubernetes Ingress NGINX maintainer Microsoft MVP 『 K8S 生态周报』发起人和维护者 GitHub：tao12345666333 Mail: zhangjintao@apache.org Agenda Agenda Kubernetes 中请求处理流程 什么是准入控制器 用 Python 实现准入控制器 与其他方案对比 Kubernetes 架构 kube-apiserver Kubernetes 集群的核心组件 处理集群内外的所有请求 Kubernetes 请求处理流程  API Handler 匹配处理链路（ /apis ）  认证 / 授权  Mutating 关操作的代码逻辑或者组件  （静态）准入控制器： Kubernetes 代码中携带，不可动 态调整的  动态准入控制器：利用 Kubernetes 提供的 MutatingAdmissionWebhook 和 ValidatingAdmissionWebhook 扩展点，由用户自行开发 的组件，接收 HTTP 回调。 为什么需要准入控制器  Kubernetes 中一系列复杂的校验 / 事务逻辑

such a system. It’s a task queue with focus on real-time processing, while also supporting task scheduling. Celery has a large and diverse community of users and contributors, you should come join us on can be set as a default, for a specific worker or individually for each task type. Read more…. Scheduling You can specify the time to run a task in seconds or a datetime, or you can use periodic tasks many short tasks and fewer long tasks, a compromise between throughput and fair scheduling. If you have strict fair scheduling requirements, or want to optimize for throughput then you should read the Optimizing
