我正在尝试在Raspberry Pi集群上设置Kubernetes。安装Docker和Kubernetes之后，我尝试使用以下命令初始化主节点：
sudo kubeadm init --apiserver-advertise-address=192.168.22.10
（192.168.22.10是此Raspberry Pi的IP地址）
我遇到了错误 error http://thyrsi.com/t6/660/1548094273x2890171671.png
Docker版本为18.09。系统为Raspbian Lite（2018-11-15）。 Kubernetes版本是1.13.2。
我尝试了以下命令：
systemctl status kubelet
然后我得到以下内容：

我已经搜索了Internet，但是找不到任何解决方案。
任何见识将不胜感激。
