在做任何读（get、list）操作时，不能假设读到 的是最新版本，也不能假设一次 reconcile 中始 终会读到同一个版本 避免写后读 同一个 controller，在一次 reconcile 中，避免写 （create、update、delete）完一个对象后马上去 读（get、list）最新版本，等controller-runtime 触发下一次 reconcile 遵循惯例开发模式 即 controller 用读 stale 对象。 如下图所示，某个版本为3（gen=3）的集群（Cluster）中有一个 stale 对象，即 StatefulSet (gen=2)。 Controller-runtime 的 Reconcile 过程是一个 EDA 模型，当该 stale 对象的更新到达 cache 时，controller-runtime 会发送一个事件（Event）给到 owner controller（也就是我们的 controller-type OwnerReference of the given type. // Use Owns(object, builder.MatchEveryOwner) to reconcile all owners. // // By default, this is the equivalent of calling // Watches(object, handler.Enqu

configCh的这个事件会被agent.Run监控到，然后调用agent.reconcile。 3. reconcile方法会启动协程执行agent.waitForExit从而启动envoy看reconcile方法名就知道是用来保证desired config和current config保持一致的。reconcile首先会检查desired config和current config是否一致，如果是的 在调用waitForExit之前会将desiredConfig赋值给currentConfig，表示reconcile工作完成 4. waitForExit会调用agent.proxy.Run，也就是envoy的Run方法，这里会启动envoy。 每次配置发生变化，都会调用agent.reconcile，也就会启动新的envoy，这样envoy越来越多，老的envoy进程怎么办？ agent代码的
