root@k8s-master:~# kubectl get node The connection to the server localhost:8080 was refused - did you specify the right host or port?
原因:使用kubeadm安装的k8s集群的/etc/kubernetes/admin.conf 为设置环境变量
解决方法设置环境变量并设置系统启动生效,并设置立即生效:
root@k8s-master:~# echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> ~/.bash_profile root@k8s-master:~# source ~/.bash_profile
