k8s子节点加入集群中时报错

[preflight] Reading configuration from the cluster...
[preflight] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -o yaml'

　　尝试方法 https://github.com/kubernetes/kubeadm/issues/1893

sudo mkdir /etc/docker
cat <<EOF | sudo tee /etc/docker/daemon.json
{
"exec-opts": ["native.cgroupdriver=systemd"],
},
}
EOF

sudo systemctl enable docker
sudo systemctl daemon-reload
sudo systemctl restart docker

　　分析原因，服务器在安装kubelet时未先安装docker，导致了此问题
