}flannel的配置,PS 在master和node上都配置了flannel
[root@localhost ~]# /root/local/bin/etcdctl --endpoints=${ETCD_ENDPOINTS} --ca-file=/etc/kubernetes/ssl/ca.pem --cert-file=/etc/kubernetes/ssl/kubernetes.pem --key-file=/etc/kubernetes/ssl/kubernetes-key.pem ls ${FLANNEL_ETCD_PREFIX}/subnets

{"PublicIP":"10.192.29.208","BackendType":"vxlan","BackendData":{"VtepMAC":"6a:06:02:bb:c2:21"}}但是通过 浏览器都不能访问UI， 比如dashboard UI: http://10.192.29.207:8080/api/v1/namespaces/kube-system/services/kubernetes-dashboard/proxy/
Error: 'dial tcp 172.30.38.2:9090: getsockopt: connection timed out'
Trying to reach: 'http://172.30.38.2:9090/'
由于dashboard 还暴露了NodePort
kube-system kubernetes-dashboard 10.254.172.131 <nodes> 80:8791/TCP 1h
所以我通过浏览器访问http://10.192.29.208:8791， 也是报同样的错误
ERROR
The requested URL could not be retrieved
The following error was encountered while trying to retrieve the URL: http://10.192.29.208:8791/
Connection to 10.192.29.208 failed.
The system returned: (110) Connection timed out

然后我在Node中curl http://10.192.29.208:8791, 是有返回正常页面内容的（虽然是浏览器不兼容的信息）
[root@localhost ~]# curl 10.192.29.208:8791
