在生成证书的 master_ssl.cnf
指定的 IP.1 = 10.254.0.1
etcdctl -C http://localhost:4001 set /coreos.com/network/config '{"Network":"10.254.0.0/16"}'
重起 flanneld

api server 启动参数 --service-cluster-ip-range=10.254.0.0/16
========================================================
kubelet 启动参数增加 --cluster-dns=10.254.0.100 --cluster-domain=cluster.local
测试 创建busybox pod
kubectl exec busybox -- nslookup svc

修改docker0 网桥的地址
./mk-docker-opts.sh -i （flannel 解压包里）
source /run/flannel/subnet.env
ifconfig docker0 $FLANNEL_SUBNET
systemctl restart docker
----------------------------------------------------
如果不行
centos7:
vi /usr/lib/systemd/system/docker.service
启动参数加上 --bip=${FLANNEL_SUBNET}
