[root@kube-master ~]# kubectl get nodesE0813 00:09:15.710990 6600 memcache.go:265] couldn't get current server API group list: Get "http://localhost:8080/api?timeout=32s": dial tcp 127.0.0.1:8080: connect: connection refused原因 KUBECONFIG这个变量没了
解决方法：
export KUBECONFIG=/etc/kubernetes/admin.conf长期解决方法：暂无
This error primarily happens due to Kubeconfig file not present in the users $HOME/.kube/config location.
把admin.conf 复制到这个目录下
参考：

$ echo $KUBECONFIG

No resources found in default namespace.
最终的解决方法：
假设你的 kubeconfig 文件位于/root/.kube/config/admin.conf ，那么你可以按照以下步骤设置：编辑 /etc/profile:
sudo vim /etc/profile添加环境变量: 在文件末尾添加以下行：
export KUBECONFIG=/root/.kube/config/admin.conf保存并退出: 保存文件并退出编辑器。使更改生效: 重新加载 /etc/profile 文件：
source /etc/profile验证设置: 检查 KUBECONFIG 是否设置正确：
echo $KUBECONFIG现在，你已经永久设置了 KUBECONFIG 环境变量，可以在任何时候使用 kubectl 命令来管理 Kubernetes 集群。
