Operator Pattern：用 Go 扩展 K8s 的最佳实践 吴学强 ApeCloud KubeBlocks Maintainer & 研发总监 目 录 认识我们 00 什么是 Operator 01 Operator 基础模型 02 Operator 最佳实践 03 我们是谁 云猿生（ApeCloud）是一家提供数据库内核与管理平台的基 础软件开发商. KubeBlocks 域的复杂有状态应用程序。 给出了用 TPR + controller- runtime 早期版本的 sample： etcd operator K8s 1.9 版本发布，CRD进入 beta 阶段并正式取代 TPR； controller-runtime 加入 K8s 社 区并正式发布； 自此，CRD + controller-runtime 逐渐成为开发 operator 的首选 Operator Operator = CRD + control loop, i.e, Declaretive API + Automation; kubebuilder + controller-runtime + helm Operator Capability Levels Installation of the workload • Operator deploys an Operand
