k8s - slave node 无法显示node信息

问题

k8s 安装成功后，在 slave node 上无法获取 node 信息

[root@k8s-node1 ~]# kubectl get node
The connection to the server localhost:8080 was refused 
				- did you specify the right host or port?

解决方案

从master 节点将 admin.conf 复制到每个节点去

[root@k8s-master k8s]# scp -r /etc/kubernetes/admin.conf root@172.xx.xx.176:/etc/kubernetes/

[root@k8s-node1 ~]# vim /root/.bash_profile
export KUBECONFIG=/etc/kubernetes/admin.conf

[root@k8s-node1 ~]# source /root/.bash_profile 
[root@k8s-node1 ~]# kubectl get pods
No resources found in default namespace.
[root@k8s-node1 ~]# kubectl get nodes
