Replication Controller(RC)是 Kubernetes 系统中核心概念之一,当我们定义了一个 RC 并提交到 Kubernetes 集群中以后,Master 节点上的 Controller Manager 组件就得到通知, 定期检查系统中存活的 Pod,并确保目标 Pod 实例的数量刚好等于 RC 的预期值,如果有过 多或过少的 Pod 运行,系统就会停掉或创建一些 Pod.此外...

Kubernetes 水平触发的 API 实现方式是:控制器监视资源对象的实际状态,并与对象期望的状态进行对比,然后调整实际状态,使之与期望状态相匹配。 水平触发的 API 也叫声明式 API,而监控 deployment 资源对象并确定符合预期的控制器就是 deployment controller,对应的 rs 的控制器就是 rs controller。
