开发给定的相关参数:
--cpu-manager-policy=static、--topology-manager-policy=best-effort
相关参数说明:
--cpu-manager-policy=static:
CPU管理器策略：static 开启CPU绑定
--topology-manager-policy=best-effort
拓扑管理器策略：best-effort 尽力亲和
官方文档的参数说明:
https://kubernetes.io/zh-cn/docs/reference/command-line-tools-reference/kubelet/
如上图所示，开发给我两个参数K8S官方都已经弃用，目前版本可能还是要用的，未来版本就必须基于配置文件的方式指定方能失效哟，我的生产环境是k8s 1.33.10版本，你得看你的自己的版本是啥。

故障分析:
上面的报错关键点是"Source /tmp/releases/kubeadm-1.33.10-amd64 not found"，说白了就是找不到文件。
先下载并分发二进制软件包到各个节点
