出现一下问题可能是证书认证错误

重新删除掉证书并生成正确的证书即可：

rm -rf $HOME/.kube/config file
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

确定要放弃本次机会？

1.问题说明搭建完k8s集群，k8s-master节点一开始还可以正常使用kubelet命令，过会后就不能正常使用率，真是气人前一秒还能用，下一秒就不行 2.问题解决方式在网上找遍了解决问题的博客，依然无法解决问题，写的一塌糊涂，都是抄袭，真的很狗 2.1.问题复现在正常的k8s集群的master节点执行以下几个命令： mkdir -p $HOME/.kube cp -i /etc/kubernetes/admin.conf $HOME/.kube/config chown $(id

kubectl get nodes运行时出现：Unable to connect to the server: x509: certificate signed by unknown authority 原因：我们在运行kubeadm reset时，没有删除原先的$HOME/.kube文件导致新建的kubelet报错。实际上在kubeadm reset执行后，系统已经提示我们需要手动删除这个配置文件。解决方法：在运行kubeadm reset之后，接着输入rm -rf $HOME/.kube删除原配置文

运行kubeadm reset清除配置后，对集群初始化也是成功的。然而当运行 kubectl get nodes 时又报错..原因：执行kubeadm reset命令后没有删除创建的.kube目录，重新创建集群就会出现这个问题！

符号链接来配置 kubelet 自动轮换客户端证书。如果此轮换过程失败，你可能会在 kube-apiserver 日志中看到诸如。文件是否包含有效证书，并在必要时重新生成证书。在 kubeconfig 文件中的证书是 base64 编码的。指向轮换的 kubelet 客户端证书，方法是将。默认情况下，kubeadm 使用。以下错误说明证书可能不匹配。命令可以用于查看证书信息。命令可以用来解码证书，使用如下方法取消设置。或者将其设置为默认的。

问题原因：node节点执行会失败，原因为nginx代理kube-apiserver配置时，upstream后端的apiserver地址配置错误，导致没有注册到正确的master节点。K8S节点上执行kubectl get node命令报错证书问题，查看kubelet日志如下。
