Docker 修改默认存储位置

• 首先使用 docker info 查看 docker 的基本信息

sudo docker infoContainers: 0Images: 5Storage Driver: devicemapper Pool Name: docker-253:0-679369-pool Pool Blocksize: 65.54 kB Backing Filesystem: extfs Data file:  Metadata file:  Data Space Used: 533.9 MB Data Space Total: 107.4 GB Data Space Available: 106.8 GB Metadata Space Used: 954.4 kB Metadata Space Total: 2.147 GB Metadata Space Available: 2.147 GB Udev Sync Supported: true Deferred Removal Enabled: false Library Version: 1.02.89-RHEL6 (2014-09-01)Execution Driver: native-0.2Logging Driver: json-fileKernel Version: 2.6.32-431.29.2.el6.x86_64Operating System: CPUs: 1Total Memory: 853.5 MiBName: rhel62buildID: LIO4:I43U:YFQU:SN45:YOE6:7GTF:6AGX:VSKQ:ICIV:AKWD:3OKQ:HUSC

这是一个新装的docker环境，其中看不出当前docker文件存储的路径。但是docker默认会使用 /var/lib/docker 作为默认存储位置。

• 停止 Docker 服务

sudo /etc/init.d/docker stop

• 将原来默认的/var/lib/docker备份一下，然后复制到别的位置并建立一个软链接

cd /var/libsudo cp -rf docker docker.baksudo cp -rf docker //sudo ln -s //docker docker

• 启动 Docker 服务

sudo /etc/init.d/docker start

• 最后使用 docker info 查看更新结果

sudo docker infoContainers: 0Images: 5Storage Driver: devicemapper Pool Name: docker-8:21-393695-pool Pool Blocksize: 65.54 kB Backing Filesystem: extfs Data file: /dev/loop1 Metadata file: /dev/loop2 Data Space Used: 533.9 MB Data Space Total: 107.4 GB Data Space Available: 15.33 GB Metadata Space Used: 954.4 kB Metadata Space Total: 2.147 GB Metadata Space Available: 2.147 GB Udev Sync Supported: true Deferred Removal Enabled: false Data loop file: /build/docker/devicemapper/devicemapper/data Metadata loop file: /build/docker/devicemapper/devicemapper/metadata Library Version: 1.02.89-RHEL6 (2014-09-01)Execution Driver: native-0.2Logging Driver: json-fileKernel Version: 2.6.32-431.29.2.el6.x86_64Operating System: CPUs: 1Total Memory: 853.5 MiBName: rhel62buildID: LIO4:I43U:YFQU:SN45:YOE6:7GTF:6AGX:VSKQ:ICIV:AKWD:3OKQ:HUSC
