kubernetes - 无法加入 VMWare 上的主节点

编程问答 2022-05-14

问题描述

我在 VMWare Workstation 上创建了 2 个 Centos 虚拟机，主节点的静态 IP 为 192.168.1.10，第一个节点的静态 IP 为 192.168.1.20。 init 在 master 上消失了，但 join 失败而没有明显的错误。 我在两台虚拟机上都使用一个以太网接口。

[root@master-node ~]# kubectl get nodes
NAME          STATUS   ROLES    AGE   VERSION
master-node   Ready    <none>   52m   v1.20.5
[root@master-node ~]# kubectl cluster-info

To further debug and diagnose cluster problems,use 'kubectl cluster-info dump'.
[root@master-node ~]# kubeadm token create --print-join-command
kubeadm join 192.168.1.10:6443 --token 9it8xw.2m37kazjusvgnjeu     --discovery-token-ca-cert-hash sha256:5d17490ab49f5a643efbe6635211466273c3dd774004eaf3db12ef7bf38bc840

和节点

root@worker-node1 ~]# kubeadm join 192.168.1.10:6443 --token 8ix113.hgprb2dp3g7e4dgp     --discovery-token-ca-cert-hash
