从节点

sudo systemctl stop kubelet

  --cri-socket unix:///var/run/cri-dockerd.sock

sudo kubeadm reset -f \
  --cri-socket unix:///var/run/containerd/containerd.sock
  
sudo rm -rf /etc/kubernetes

sudo kubeadm join 192.168.3.60:6443 --token qwiu6c.xjwz2f2yt8i6sizk         --discovery-token-ca-cert-hash sha256:358d3c01bf77079c204e1a614ad0b98c32eae215807209669f42a6c394a   --cri-socket unix:///var/run/cri-dockerd.sock --v=5

问题

kubectl --kubeconfig=/etc/kubernetes/admin.conf \
-n kube-public get cm cluster-info -o yaml

需要有jws-kubeconfig-qwiu6c
