k8s主节点报错：The connection to the server localhost:8080 was refused - did you specify the right host or port?

现象：

[root@k8s-master01 ~]# kubectl get nodes
The connection to the server localhost:8080 was refused - did you specify the right host or port?

 

 

原因：

网络没有搭建，搭建网络即可（细心的小伙伴会发现集群初始化时就有这个内容提示的）

[root@k8s-master01 home]#   mkdir -p $HOME/.kube
[root@k8s-master01 home]#   sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
[root@k8s-master01 home]#   sudo chown $(id -u):$(id -g) $HOME/.kube/config
