KubeCon + CloudNativeCon + Open Source Summit + AI_dev China 2024

Kubernetes provides StatefulSet to manage stateful services, but it is far from enough to run enterprise stateful applications in practice. For example: how does Zookeeper accomplish leader election, and how does MQ implement configuration hot loading? How to do daily operation and maintenance of the database? Many practitioners resort to operators that manages  pod directly e.g. KubeBlocks,  for specific applications e.g. database, yet  they are not general enough for  other stateful applications.   OpenKruise provides several stateful features that are missing in native StatefulSet, such as in-place resource and volume resizing, progressive Configmap & Secret hot update and container operation channel. Teams from Alibaba and Xiaohongshu will share their lessons to build operators and platforms for general stateful apps and containerize database and middleware with a scale of hundreds of thousands of pods.

Kubernetes提供了StatefulSet来管理有状态服务，但实际上要运行企业级有状态应用还远远不够。例如：Zookeeper如何完成领导者选举，MQ如何实现配置热加载？如何进行数据库的日常运维？许多从业者借助直接管理pod的运营商，例如KubeBlocks，针对特定应用程序，例如数据库，但它们并不足够通用以适用于其他有状态应用程序。 OpenKruise提供了一些在原生StatefulSet中缺失的有状态功能，例如原地资源和卷大小调整，渐进式Configmap和Secret热更新以及容器操作通道。来自阿里巴巴和小红书的团队将分享他们构建运营商和平台以适用于通用有状态应用程序，并将数据库和中间件容器化的经验，规模达数十万个pod。
