K8S Node节点报错The connection to the server localhost:8080 was refused - did you specify the right host or port?
 

 

今天在Kubernetes的从节点上运行命令【kubectl】出现了如下错误

[root@k8snode1 kubernetes]# kubectl get pod


The connection to the server localhost:8080 was refused - did you specify the right host or port?


出现这个问题的原因是kubectl命令需要使用kubernetes-admin来运行,解决方法如下,将主节点中的【/etc/kubernetes/admin.conf】文件拷贝到从节点相同目录下,然后配置环境变量:

echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> ~/.bash_profile


立即生效

source ~/.bash_profile


在运行kubectl命令就成功了
