我正在试验集群或 生产环境 集群上的6个节点（在两个节点池中）测试集群中进行GKE集群升级 . 升级时，我只有12个副本nginx部署，nginx入口控制器和cert-manager（作为helm图表）安装每个节点池需要10分钟（3个节点） . 我很满意 . 我决定再试一次看起来更像我们设置的东西 . 我删除了nginx部署并添加了2个node.js部署，以下是头盔图：mongodb-0.4.27，mcrouter-0.1.0（作为statefulset），redis-ha-2.0.0，以及我自己的www-redirect- 0.0.1图表（进行重定向的简单nginx） . 问题似乎与mcrouter有关 . 节点开始耗尽后，该节点的状态将更改为 Ready,SchedulingDisabled （这似乎正常），但仍保留以下窗格：

• mcrouter-memcached-0

• fluentd-gcp-v2.0.9-4f87t

• kube-proxy-gke-test-upgrade-cluster-default-pool-74f8edac-wblf

我不知道为什么这两个kube系统吊舱仍然存在，但那个mcrouter是我的，并且它不会足够快 . 如果我等待足够长的时间（1小时），那么它最终会起作用，我不知道为什么 . 当前节点池（3个节点）在2h46分钟前开始升级，2个节点升级，第3个节点仍在升级，但没有任何动态......我认为它将在接下来的1-2个小时内完成...我试过了使用 --ignore-daemonsets --force 运行排水命令，但它告诉我它已经耗尽了 . 我试图删除pod，但他们只是回来了，升级不会更快 . 有什么想法吗？

mcrouter helm图表安装如下：

helm install stable/mcrouter --name mcrouter --set controller=statefulset

它为mcrouter部分创建的状态集是：
