  • k8s的worker node节点运行kubectl报错:The connection to the server localhost:8080 was refused

    一、现象

    [root@redis-01 kubernetes]# kubectl get pods
    The connection to the server localhost:8080 was refused - did you specify the right host or port?
    [root@redis-01 kubernetes]# 

    二、原因

    kubectl运行需要使用kubernetes-admin来运行

    三、解决

    1、将master节点的/etc/kubernetes/admin.conf复制从node节点的/etc/kubernetes目录下

    [root@master69 kubernetes]# scp -P25601 admin.conf root@172.28.5.120:/etc/kubernetes/

    2、配置环境变量KUBECONFIG

    [root@redis-01 kubernetes]# echo "export KUBECONFIG=/etc/kubernetes/admin.conf">>/etc/profile
    [root@redis-01 kubernetes]# source /etc/profile
    [root@redis-01 kubernetes]# echo $KUBECONFIG
    /etc/kuberbetes/admin.conf

    3、执行验证

    [root@redis-01 kubernetes]# kubectl get pods -n kube-system
