加入x509:证书已过期或尚未生效

Question

将centos 7节点加入群集1.9.0时,kubeadm join命令会显示此错误消息.

Failed to request cluster info, will try again: [Get https://10.10.10.10:6443/api/v1/namespaces/kube-public/configmaps/cluster-info: x509: certificate has expired or is not yet valid]

我昨天晚上得到了这条消息,今天早上运行这个命令时它起了作用.我今天早上删除并尝试创建群集,同样给出相同的错误消息.

kubeadm join --token f115fe.f0eea05182abe63a 10.10.10.10:6443 --discovery-token-ca-cert-hash sha256:48d4dc90a08ff73a0cfc63e30a313aaf1903fd51da8f9ce4cc79f95ce529b8d1

如何解决此错误消息？

谢谢SR

问题的根本原因是我的节点没有正确的时间.配置NTP服务节点后,能够加入主节点.
