Eu tentei juntar nós do kubernetes com o mestre, mas ele mostra erros em todos os 3 nós. mostrado na foto

Question

Todo nó mostra este erro enquanto eu tentei juntar esses nós com o Kubernetes master. Alguma sugestão?

[root@kube-node1 ~]#  kubeadm join 10.0.0.50:6443 --token xtalee.aftgxumqvtjtcq56 --discovery-token-ca-cert-hash sha256:d0f97b9d53be798a6ab871a2fd8271ee6461b9fd6fdc6350eb89ebee98629ac6
[preflight] running pre-flight checks
        [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_rr:{} ip_vs_wrr:{} ip_vs_sh:{} nf_conntrack_ipv4:{} ip_vs:{}]
you can solve this problem with following methods:
 1. Run 'modprobe -- ' to load missing kernel modules;
2. Provide the missing builtin kernel ipvs support

[preflight] If you know what you are doing, you can make a check non-fatal with '--ignore-preflight-errors=...'
