之前openstack平台由于停电等影响，导致之前制作的registry 私有仓库的主机挂掉，还好数据挂载在nfs中，然后现在尝试重新启动恢复。
虚机安装nfs服务
apt-get install -y nfs-common
编辑 /etc/fstab
写入远程挂载地址
10.50.8.12:/export/DockerRepo /var/lib/docker/registry nfs defaults 0 0
然后进行挂载：
mount -a -v
输出如下结果，表明mount成功

mount.nfs: trying text-based options 'vers=4,addr=10.50.8.12,clientaddr=10.0.0.244'
nothing was mounted

可以用df来查看：

创建新的registry
命令如下
# docker run -d -p 5000:5000 -v /var/lib/docker/registry:/tmp/registry registry
其中 －p是与主机进行端口映射，－v表示将主机的volume挂载到容器中，即将我们的nfs挂载到容器中，作为Docker 私有仓库的存储使用。
查看是否创建成功
用curl命令来search其中的仓库文件是否存在：

root@docker-registry:/var/lib/docker/registry/images# curl http://127.0.0.1:5000/v1/search
{"num_results": 8, "query": "", "results": [{"description": null, "name": "shipyard/rethinkdb"}, {"description": null, "name": "shipyard/shipyard"}, {"description": null, "name": "shipyard/shipyard-cli"}, {"description": null, "name": "library/mysql"}, {"description": null, "name": "library/ubuntu"}, {"description": null, "name": "library/registry"}, {"description": null, "name": "library/centos"}, {"description": null, "name": "tutum/influxdb"}]}

测试私有仓库
从私有仓库拉取ubuntu：14.04镜像。

从私有仓库只需要10多秒即可将ubuntu的200多m的镜像给pull下来。
