# 删除程式檔案
sudo rm -rf /root/local/bin/etcd

# 删除TLS證書檔案
sudo rm -rf /etc/etcd/ssl/*
           

清除K8s叢集的Master節點

sudo systemctl stop kube-apiserver kube-controller-manager kube-scheduler flanneld
           

# 删除kube-apiserver工作目錄
sudo rm -rf /var/run/kubernetes

# 删除service檔案
sudo rm -rf /etc/systemd/system/{kube-apiserver,kube-controller-manager,kube-scheduler,flanneld}.service

# 删除證書檔案
sudo rm -rf /etc/flanneld/ssl /etc/kubernetes/ssl

# 删除kubelet緩存
sudo rm -rf ~/.kube/cache ~/.kube/schema
           

清除K8s叢集的Node節點

sudo systemctl stop kubelet kube-proxy flanneld docker
           

# umount kubelet 挂載的目錄
mount | grep '/var/lib/kubelet'| awk '{print $3}'|xargs sudo umount

# 删除kubelet工作目錄
sudo rm -rf /var/lib/kubelet

# 删除docker工作目錄
sudo rm -rf /var/lib/docker

# 删除flanneld寫入的網絡配置檔案
sudo rm -rf /var/run/flannel/

# 删除service檔案
sudo rm -rf /etc/systemd/system/{kubelet,docker,flanneld}.service

# 删除程式檔案
sudo rm -rf /root/local/bin/{kubelet,docker,flanneld,mk-docker-opts.sh}

# 删除證書檔案
sudo rm -rf /etc/flanneld/ssl /etc/kubernetes/ssl
