application-specific controller that extends the Kubernetes API to create, configure and manage instances of complex stateful applications on behalf of a Kubernetes user. operator 是特殊的 controller，用来管理复杂的分布式应用 应用 ü custom resource definition(CRD) ü custom controller Operator 是什么 • Kubernetes 中一切都可视为资源 • 默认资源类型：如 Pod、Service、Volume 等 • Kubernetes 1.7 之后增加了 CRD 自定义资源 • 二次开发扩展 Kubernetes API CRD 的基本原理 API 消除差别 TestCluster app=test app=test 申请扩容 期望副本数：3 当前副本数：1 VS app=test 增加2个副本 当前副本数：3 Controller 的基本原理 1. 背景介绍 2. Operator 的基本原理 3. MySQL Operator 设计实践 4. 小结 MySQL 容器化目标 • 快速部署 MySQL 主从集群
