1、简述flannel原理及实现过程
1.1 原理
#每个node分配pod网段下的独立子网，24位掩码 # cat /run/flannel/subnet.env #flannel网络模型： UDP #使用UDP封装完成报文跨主机传输，生产不使用 VXLAN #本质为一种tunnel(隧道)协议，基于3层网络实现虚拟2层网络 VXLAN_Directrouting，在同一二层网络中的node节点启用直接路由机制，类似host-gw模式 Host-gw #要求node节点处于同一局域网当中，通过在node节点创建到达目标节点的路由实现报文转发 #组件： cni0 #网桥设备，cni0连接pod内部eth0，cni0占用分配的pod网段的第一个可用地址 flannel.1 #overlay网络设备，用于VXLAN报文封装与解封装，不同node之间的pod通过flannel.1以隧道的形式通信
1.2 不同网络模型的实现过程
