我正在使用kubeadm创建一个kubernetes集群 . Kubeadm init成功了 . 但是当我尝试添加节点时，我看到了这个错误 . 任何方向都受到高度赞赏 .
kubeadm join 10.127.0.142:6443 --token ddd0 --discovery-token-ca-cert-hash sha256:ddddd

[WARNING RequiredIPVSKernelModulesAvailable]: the IPVS proxier will not be used, because the following required kernel modules are not loaded: [ip_vs_sh ip_vs ip_vs_rr ip_vs_wrr] or no builtin kernel ipvs support: map[ip_vs_sh:{} nf_conntrack_ipv4:{} ip_vs:{} ip_vs_rr:{} ip_vs_wrr:{}]
you can solve this problem with following methods:
1. Run 'modprobe -- ' to load missing kernel modules;
2. Provide the missing builtin kernel ipvs support

我很确定您的主节点和工作节点上的版本不匹配 .
按照this official说明将群集升级到相同版本 .
第二种解决方案是将工作节点降级为主节点版本
