Docker - Image创建

自己创建Image会有一些好处，可以选择最新的版本，而且从国内的镜像创建时更新软件也会从该镜像获取，速度更快。

（1）安装debootstrap

zhouh1@uhome:/media/zhouh1/databak/docker$ sudo apt-get install debootstrap 
Reading package lists... Done

以下为关于这个包的介绍

Description: Bootstrap a basic Debian system
 debootstrap is used to create a Debian base system from scratch, without requiring the availability of dpkg or apt. It does this by downloading .deb files from a mirror site,
 and carefully unpacking them into a directory which can eventually be chrooted into.

 

（2）创建基础系统

zhouh1@uhome:/mnt/data/docker$ sudo debootstrap trusty trusty http://mirrors.163.com/ubuntu/

I: Retrieving Release.gpg 
I: Checking Release signature
I: Valid Release signature (key id 790BC7277767219C42C86F933B4FE6ACC0B21F32)

I: Base system installed successfully

（3）导入到docker

zhouh1@uhome:/mnt/data/docker/trusty$  sudo tar -c . | sudo docker import - trusty

（4）测试

zhouh1@uhome:/mnt/data/docker/trusty$ sudo docker run -i -t trusty /bin/bash
root@2d66c560066c:/# test
root@2d66c560066c:/# echo

root@2d66c560066c:/# exit
