flanneld启动报错Container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

这个报错就是配置文件里面写错了，主要是启动脚本里面，比如我这里就是

ExecStart=/usr/local/bin/flanneld   -etcd-cafile=/etc/etcd/ssl/ca.pem   -etcd-certfile=/etc/etcd/ssl/server.pem   -etcd-keyfile=/etc/etcd/ssl/server-key.pem   -etcd-endpoints=https://192.168.50.128:2379,https://192.168.50.129:2379,https://192.168.50.130:2379   -etcd-prefix=/coreos.com/network   -iface=ens33   -ip-masq

这里面其中有一行-etcd-prefix选项，这个不能写错，不能多写。我之前是写成了/coreos.com/network/config了，多写了，结果报错了，也是找了一段时间才解决。
