k8s报错：The connection to the server localhost:8080 was refused

现象

k8s节点使用kubectl get pods --all-namespaces报错

[root@node1 ~]# kubectl get pods --all-namespaces

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

原因

该节点未对kubernetes进行配置

解决办法

拷贝master节点的/etc/kubernetes/admin.conf配置文件到/etc/kubernetes/目录下，并执行如下命令

mkdir -p $HOME/.kube

  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

  sudo chown $(id -u):$(id -g) $HOME/.kube/config
