Docker 私有倉(cāng)庫(kù)恢復(fù)
之前openstack平臺(tái)由于停電等影響，導(dǎo)致之前制作的registry 私有倉(cāng)庫(kù)的主機(jī)掛掉，還好數(shù)據(jù)掛載在nfs中，然后現(xiàn)在嘗試重新啟動(dòng)恢復(fù)。
虛機(jī)安裝nfs服務(wù)
apt-get install -y nfs-common
編輯 /etc/fstab
寫(xiě)入遠(yuǎn)程掛載地址
10.50.8.12:/export/DockerRepo /var/lib/docker/registry nfs defaults 0 0
然后進(jìn)行掛載：
mount -a -v
輸出如下結(jié)果，表明mount成功
root@docker-registry:/home/ubuntu# mount -a -vmount.nfs: timeout set for Thu Mar 26 13:12:44 2015mount.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# dfFilesystem 1K-blocks Used Available Use% Mounted on/dev/vda1 165106028 1780156 156584392 2% /none 4 0 4 0% /sys/fs/cgroupudev 8211996 12 8211984 1% /devtmpfs 1643392 348 1643044 1% /runnone 5120 0 5120 0% /run/locknone 8216952 0 8216952 0% /run/shmnone 102400 0 102400 0% /run/user10.50.8.12:/export/DockerRepo 515931136 683008 489017344 1% /var/lib/docker/registry
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:14.04Pulling repository 127.0.0.1:5000/ubuntu2103b00b3fdf: 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
然后可以通過(guò)docker images來(lái)查看存在的images：
root@docker-registry:/var/lib/docker/registry/images# docker imagesREPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZEregistry latest e33e81d7024c 5 days ago 413.7 MB127.0.0.1:5000/ubuntu latest 2103b00b3fdf 2 weeks ago 192.7 MB127.0.0.1:5000/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)。
