rancher2:cni config uninitialized

部署rancher2时踩了个坑

向集群添加主机时候主机启动报错:

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

google到了解决方法;

sudo mkdir -p /etc/cni/net.d
sudo cat > /etc/cni/net.d/10-flannel.conflist <<EOF
