已加入集群的，所有节点都要修改 /var/lib/kubelet/kubeadm-flags.env 内容 未加入集群的，执行加入命令时添加--cri-socket选项： # kubeadm join x.x.x.x:6443 --token xxxx \ --discovery-token-ca-cert-hash xxxxxxxx --cri-socket unix:///var/run/cri- systemctl enable kubelet # systemctl start kubelet 再加入K8S集群（使用 安装第一个k8s的master结点时生成的最后2行命令 kubeadm join xxx）不过这命令的token默认是2小时有效期，超时后可重新生成 token再去node结点上执行 master1结点# kubeadm token generate master1 结 点 # kubeadm token create ka8k02.9f2uowba7j21qv0g --print-join- command 再复制（kubeadm join xxxxx）命令到node结点上执行： node结点执行# kubeadm join 10.99.1.51:6443 --token ka8k02.9f2uowba7j21qv0g \ --discove
