[reset] Deleting contents of config directories: [/etc/kubernetes/manifests /etc/kubernetes/pki]
[reset] Deleting files: [/etc/kubernetes/admin.conf /etc/kubernetes/kubelet.conf /etc/kubernetes/bootstrap-kubelet.conf /etc/kubernetes/controller-manager.conf /etc/kubernetes/scheduler.conf]

The reset process does not clean CNI configuration. To do so, you must remove /etc/cni/net.d
The reset process does not reset or clean up iptables rules or IPVS tables.
If you wish to reset iptables, you must do so manually by using the "iptables" command.
If your cluster was setup to utilize IPVS, run ipvsadm --clear (or similar)
to reset your system's IPVS tables.
The reset process does not clean your kubeconfig files and you must remove them manually.
Please, check the contents of the $HOME/.kube/config file.
手工清除:
刪除net.d
rm -rf /etc/cni/net.d
重置iptables
iptables -F && iptables -t nat -F && iptables -t mangle -F && iptables -X
sysctl net.bridge.bridge-nf-call-iptables=1
手動(dòng)執(zhí)行以下命令來清除對(duì)應(yīng)的殘余網(wǎng)卡信息:
sudo ip link del cni0
sudo ip link del flannel.1
刪除 $HOME/.kube/config
rm -rf $HOME/.kube/config
