要使用重新安装我的本地集群kubeadm，我运行了以下命令：
sudo apt-get purge -y kubeadm kubectl kubelet kubernetes-cni kubelet kube-apiserver kube-scheduler kube-controller-manager kube-proxy
sudo apt-get autoremove -y
然后重新启动我的机器。
奇怪的是，我仍然使用 ps 发现许多 kube 进程：

但是以 root 身份，我无法在目录中找到这些文件（例如 kube-proxy、kubelet、kube-apiserver 和 kube-scheduler）：
(base) ➜ ~ ll /usr/bin/kubelet
ls: cannot access '/usr/bin/kubelet': No such file or directory
(base) ➜ ~ kubectl
zsh: command not found: kubectl
(base) ➜ ~
(base) ➜ ~ sudo kube-apiserver --help
sudo: kube-apiserver: command not found
(base) ➜ ~ cd /usr/bin
(base) ➜ bin ls kubelet
ls: cannot access 'kubelet': No such file or directory
(base) ➜ bin ll kube-controller-manager
ls: cannot access 'kube-controller-manager': No such file or directory
(base) ➜ bin ll kube-apiserver
ls: cannot access 'kube-apiserver': No such file or directory
有人能帮忙解释一下这些过程是如何启动的吗？谢谢。
