root@docker-registry:/home/ubuntu# mount -a -v
mount.nfs: timeout set for Thu Mar 26 13:12:44 2015
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來(lái)查看：

root@docker-registry:/home/ubuntu# df

創(chuàng)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是與主機(jī)進(jìn)行端口映射，－v表示將主機(jī)的volume掛載到容器中，即將我們的nfs掛載到容器中，作為Docker 私有倉(cāng)庫(kù)的存儲(chǔ)使用。

查看是否創(chuàng)建成功

用curl命令來(lái)search其中的倉(cāng)庫(kù)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"}]}

測(cè)試私有倉(cāng)庫(kù)

從私有倉(cāng)庫(kù)拉取ubuntu：14.04鏡像。

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

4faa69f72743: Download complete 
Status: Downloaded newer image for 127.0.0.1:5000/ubuntu:14.04

然后可以通過(guò)docker images來(lái)查看存在的images：

root@docker-registry:/var/lib/docker/registry/images# docker images
REPOSITORY       TAG         IMAGE ID      CREATED       VIRTUAL SIZE
registry        latest       e33e81d7024c    5 days ago     413.7 MB
127.0.0.1:5000/ubuntu  latest       2103b00b3fdf    2 weeks ago     192.7 MB
127.0.0.1:5000/ubuntu  14.04        2103b00b3fdf    2 weeks ago     192.7 MB

從私有倉(cāng)庫(kù)只需要10多秒即可將ubuntu的200多m的鏡像給pull下來(lái)。
