k8s的node节点加入失败[ERROR FileAvailable--etc-kubernetes-kubelet.conf]: /etc/kubernetes...

问题：在第一次误操作kubeadm join …（token那条数值），再次加入后开始报错

[root@node1 docker]# kubeadm join 192.168.100.11:6443 --token ic5ini.t9zygpbu0z9                                   z7qjh     --discovery-token-ca-cert-hash sha256:92aa113eec58b64b0fc532ffbb7a7349                                   5970c52e4aa6f2a6d77b0320dda6fe00

原因：已经加入过一次，需要先清除，重置后再加入
在node节点执行kubeadm reset
