k8s问题记录

# error: You must be logged in to the server (the server has asked for the client to provide credentials)

解决：
    sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
    sudo chown $(id -u):$(id -g) $HOME/.kube/config
注意：
    不能使用：
        echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> ~/.bash_profile
        source  ~/.bash_profile
    否则 ssh 远程 执行会有问题

## 交换分区开着导致 k8s 不能进行初始化

#查看现有的交换分区
root@master1:~# swapon -s
Filename				Type		Size	Used	Priority
/dev/sda2                              	partition	3906556	1036	-2

#关闭所有的交换分区
root@master1:~# swapoff -a

#再次查看  已经没有打开的交换分区了
root@master1:~# swapon -s
