【问题描述】:
我正在尝试通过 VMS 设置 K8S 并成功安装主节点。
kubectl get nodes -o wide
master Ready control-plane,master 14m v1.20.1 192.168.5.13 <none> Ubuntu 18.04.5 LTS 4.15.0-124-generic docker://18.6.3
并且worker节点也准备安装ocker、kubeadm、kubectl和kubelet。防火墙已禁用,master 和 worker 上的交换也已关闭。
当我尝试在 worker 上以 root 身份运行时:
kubeadm join 192.168.5.13:6443 --token pk2b8n.i89ywir9vs7cqm7n --discovery-token-ca-cert-hash sha256:e9214f892d58196fa6608968f82965113e5dc1928c00d7cf066b52ae4d7037f0 --control-plane
得到下面的错误

我无法处理它。有什么帮助吗?我会很感激的。
