Kubernetes-kubectl命令出現錯誤【The connection to the server localhost:8080 was refused - did you specif...

今天在Kubernetes的從節點上運行命令【kubectl】出現了如下錯誤

[root@k8snode1 kubernetes]# kubectl get pod
The connection to the server localhost:8080 was refused - did you specify the right host or port?

解決：

出現這個問題的原因是kubectl命令需要使用kubernetes-admin來運行，解決方法如下，將主節點中的【/etc/kubernetes/admin.conf】文件拷貝到從節點相同目錄下，

[root@k8s-node01 kubernetes]# echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> ~/.bash_profile
[root@k8s-node01 kubernetes]# source ~/.bash_profile
[root@k8s-node01 kubernetes]# kubectl get pod -o wide
