您好，部署flannel的时候报了这个错Watch subnets: failed to retrieve subnet leases: context canceled，网上也查不到相关的解决办法

看起来是网络超时引起的。

192.168.20.177 是你的缺省路由所在的网络接口地址么？

我也遇到了这样的问题，后来发现flanneld.service中mk-docker-opts.sh的路径写错了，改正后重启竟然就解决这个问题了，我看mk-docker-opts.sh脚本并没有太多内容，只是很简单的生成Docker相关变量而已，虽然不太搭边，但你可以作为参考检查一下。

flanneld.service export IFACE=eth0 等于你的 网卡名称

可以同步一下 各个节点的时钟试试 我也遇到了 同步一下时钟就好了。

我遇到这个是因为mk-docker-opts.sh被写入了^M导致的
