Unable to connect to the server: x509: certificate signed by unknown a报错

执行查看节点出现以下报错

[root@k8s-master ~]# kubectl get node

Unable to connect to the server: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while tryingrity certificate "kubernetes")

解决方法：

  Master节点执行以下命令

  mkdir -p $HOME/.kube

  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

  sudo chown $(id -u):$(id -g) $HOME/.kube/config

重新执行

[root@k8s-master ~]# kubectl get nodes
