kubeadm init --kubernetes-version=v1.13.0 --pod-network-cidr=10.244.0.0/16 --service-cidr=10.96.0.0/12

执行其他安装步骤

子节点执行

kubeadm reset

systemctl daemon-reload && systemctl restart kubelet

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

kubeadm join 192.168.7.216:6443 --token 0maa49.j06ekdfhdul7p8kf \
    --discovery-token-ca-cert-hash sha256:88b6e9c3f0687260bdbb0137c8baa340fd6708563fe59a1b319864d5163289cc 

如果token当时忘记保存了，通过kubeadmin token list也可查到join验证信息
