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

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。

root@docker-registry: /var/lib/docker/registry/images # docker pull 127.0.0.1:5000/ubuntu:14.04 Pulling repository 127.0.0.1:5000 /ubuntu 2103b00b3fdf: Download complete 511136ea3c5a: Download complete f0dde87450ec: Download complete 76b658ecb564: Download complete 4faa69f72743: Download complete Status: Downloaded newer image for 127.0.0.1:5000 /ubuntu :14.04 |
然后可以通过docker images来查看存在的images:

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。
