ARM体系下如何安装kubernetes集群

docker run -d \
--name rancher-server \
--restart=unless-stopped \
-p 9443:443 \
-v /data/docker/container/rancher/data/:/var/lib/rancher/ \
 rancher/rancher:v2.4.3-linux-arm64

报错，通过以下脚本解决

# 停止服务

# 清理Iptables表
## 注意：如果节点Iptables有特殊配置，以下命令请谨慎操作
sudo iptables --flush
sudo iptables --flush --table nat
sudo iptables --flush --table filter
sudo iptables --table nat --delete-chain
sudo iptables --table filter --delete-chain
systemctl restart docker

报错和解决方案： 纳管kubernetes的时候，报了一个下面的错误。试了很久，找到了下面的解决方案。留此备忘，以待来者！惭愧！

Runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

这里有个需要注意的点的就是arm64下面不支持calico， 后来选用flannel。就解决了问题 参考文献：
