部署

可先参考 http://blog.51cto.com/hequan/2327820 部署etcd

cd /data/ssl/etcd/

/opt/etcd/bin/etcdctl --ca-file=ca.pem --cert-file=server.pem --key-file=server-key.pem --endpoints="https://192.168.100.100:2379,https://192.168.100.101:2379,https://192.168.100.102:2379" set /coreos.com/network/config  ‘{ "Network": "172.17.0.0/16", "Backend": {"Type": "vxlan"}}‘

systemctl daemon-reload
systemctl start flanneld
systemctl enable flanneld
systemctl restart docker

检查

ps -ef |grep docker
ip addr

确保docker0与flannel.1在同一网段。
测试不同节点互通，在当前节点访问另一个Node节点docker0 IP
如果能通说明Flannel部署成功。如果不通检查下日志：journalctl -u flannel
