1.安装Flanne（构建overlay网络）
Flannel网络原理

yum install flannel
vi /etc/sysconfig/flanneld

Flanneld configuration options
etcd url location. Point this to the server where etcd runs
FLANNELETCDENDPOINTS="http://etcd:2379"

etcd config key. This is the configuration key that flannel queries
For address range assignment
FLANNELETCDPREFIX="/atomic.io/network"

Any additional options that you want to pass
FLANNEL_OPTIONS=""

etcdctl mk /atomic.io/network/config '{ "Network": "192.168.0.0/16" }' 
{ "Network": "192.168.0.0/16" }

master

systemctl enable flanneld.service 

systemctl start flanneld.service 

service docker restart 

systemctl restart kube-apiserver.service 

systemctl restart kube-controller-manager.service 

systemctl restart kube-scheduler.service

node

systemctl enable flanneld.service 

systemctl start flanneld.service 

service docker restart 

systemctl restart kubelet.service 

systemctl restart kube-proxy.service

看获取的ip地址是否正确

kubectl get pods --all-namespaces -o wide 

vi kubernetes-dashboard.yaml
