补充说明：
注：etcdctl -C http://****:2379 set /atomic.io/network/config '{"Network":"172.17.0.0/16"}'这个命令nodes也要执行。Master如执行不成功，则执行etcdctl set /atomic.io/network/config '{"Network":"172.17.0.0/16"}'
(http如果不加上，高版本会有问题)
/etc/kubernetes/apiserver中--service-cluster-ip-range=172.17.0.0/16（值要改成这样）
vim /etc/kubernetes/config 中KUBE_ALLOW_PRIV="--allow-privileged=true"（仅限node）
vim /etc/kubernetes/kubelet中KUBELET_ADDRESS="--address=0.0.0.0"；KUBELET_ARGS="--cluster-dns=172.16.223.13 --cluster-domain=cluster.local. --allow-privileged=true"
nodes节点添加服务
(slave:)systemctl start flanneld docker kubelet kube-proxy; systemctl enable flanneld docker kubelet kube-proxy;
master:systemctl restart etcd kube-apiserver kube-scheduler kube-controller-manager
slave:systemctl restart flanneld docker kubelet kube-proxy
nodes节点中/etc/etcd/etcd.conf的配置不用修改
说明：
1、service有clusterip和node port两个端口，一个是对内，一个是对外

如果docker0:ip地址不对的话，重装docker和kubectl node就可以解决
