从haubxy的kubernetes-etcd检索端点

我试图从我的kubernetes-etcd-cluster使用confd检索haproxy的kubernetes端点。从haubxy的kubernetes-etcd检索端点

当执行confd它总是返回一个错误，该键“/注册表”不能找到：

$ ./confd-0.12.0-linux-amd64 -config-file confd.toml 
... 
INFO Backend nodes set to https://10.31.9.49:2379 
DEBUG Loading template resources from confdir /root/haproxy/kubernetes-endpoint-proxy/src/etc/confd/ 
DEBUG Found template: /root/haproxy/kubernetes-endpoint-proxy/src/etc/confd/conf.d/haproxy.toml 
DEBUG Loading template resource from /root/haproxy/kubernetes-endpoint-proxy/src/etc/confd/conf.d/haproxy.toml 
DEBUG Retrieving keys from store 
DEBUG Key prefix set to/
ERROR 100: Key not found (/registry) [2540]

但随着etcdctl上市在/下面“/注册表”工作正常。

$ etcdctl \ 
--cacert=/etc/kubernetes/ssl/ca.pem \ 
--cert=./admin1.pem \ 
--key=./admin1-key.pem \ 
--endpoints 10.31.9.49:2379 \ 
get/--keys-only=true --prefix \ 
| grep endpoints 
/registry/services/endpoints/default/echoheaders-x 
/registry/services/endpoints/default/echoheaders-y 
/registry/services/endpoints/default/kubernetes 
/registry/services/endpoints/kube-system/default-http-backend

/registry/services/endpoints/kube-system/kube-dns 
/registry/services/endpoints/kube-system/kube-scheduler 
/registry/services/endpoints/kube-system/kubernetes-dashboard

单个端点的作品，以及：

etcdctl \ 
--cacert=/etc/kubernetes/ssl/ca.pem \ 
--cert=./admin1.pem \ 
--key=./admin1-key.pem \ 
--endpoints 10.31.9.49:2379 get /registry/services/endpoints/default/echoheaders-x 
/registry/services/endpoints/default/echoheaders-x

清单同一端点如上，卷曲失败，但：

curl \ 
--cacert /etc/kubernetes/ssl/ca.pem \ 
--cert ./master01.pem \ 
--key ./master01-key.pem \ 
-L 'https://10.31.9.49:2379/v2/keys/registry/services/endpoints/default/echoheaders-x' 
{"errorCode":100,"message":"Key not found","cause":"/registry","index":2540}

为什么不能我列出与卷曲什么，而etcdctl作品？

任何人都可以对此有所了解吗？
