附录A 利用Raspberry Pi搭建Kubernetes群集 ......................................................................195
作者主要从事数据中心网络解决方案的研发与部署，技术方向包括云计算、软件定义网络（SDN）、网络安全等，是国内较早从事 SDN 和网络虚拟化相关技术的推广者，同时也是 Docke开源社区的发起人之一。
本书作者一直在Google和其他公司从事Kubernetes方面的工作，为我们解释了该系统如何融入分布式应用程序的生命周期之中的。你将学习如何使用各种工具和API来实现可扩展分布式系统管理的自动化，无论该系统用于在线服务、机器学习应用程序，还是Raspberry Pi计算机群集。本书的主要内容有：探索Kubernetes所面临的分布式系统挑战。使用Docker等容器进行容器化应用开发。使用docker镜像格式和容器运行时在Kubernetes上创建和运行容器。探索在生产中运行应用程序所必需的专门对象。在无需停机或无差错情况下可靠地推出新的软件版本。举例说明如何在Kubernetes中开发和部署真实应用程序。
