K8S/Kubernetes

admin.conf文件操作:

报错信息：

[root@localhost ~]# kubectl get nodes
error: no configuration has been provided, try setting KUBERNETES_MASTER environment variable

解决：

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

解决问题后展示

[root@localhost ~]# kubectl get nodes
