Docker - debian 7 安装

Docker 是一个开源的应用容器引擎，让开发者可以打包他们的应用以及依赖包到一个可移植的容器中，然后发布到任何流行的Linux机器上，也可以实现虚拟化。容器是完全使用沙箱机制，相互之间不会有任何接口（类似iPhone的app）。几乎没有性能开销,可以很容易地在机器和数据中心中运行。最重要的是,他们不依赖于任何语言、框架或包装系统。

Docker安装

如果你想安装最新版本的docker，首先，检查你的APT系统能够处理https的url：如果你的主机不存在/usr/lib/apt/methods/https文件，请先安装apt-transport-https包

Done The following NEW packages will beinstalled: apt-transport-https 0 upgraded, 1 newly installed, 0 toremove and 22 not upgraded. Need to get 109 kB of archives. After this operation, 166 kB ofadditional disk space will be used. Get:1 http://http.debian.net/debian/wheezy/main apt-transport-https amd64 0.9.7.9+deb7u2 [109 kB] Fetched 109 kB in 3s (29.0 kB/s) Selecting previously unselectedpackage apt-transport-https.

然后，添加docker镜像秘钥到你的本地秘钥库.

添加Docker镜像添加你的apt软件源,更新和安装lxc-docker包。你可能会受到一个警告信息，这个包不可信，输入yes继续安装。

root@linux:/home/docker# echo debhttps://get.docker.io/ubuntu docker main >/etc/apt/sources.list.d/docker.list root@linux:/home/docker# cat/etc/apt/sources.list.d/docker.list deb https://get.docker.io/ubuntu docker main

提示：这还有一个简单的curl脚本来协助你完成这一工作。

$curl -s https://get.docker.io/ubuntu/ | sudo sh

注意：Ubuntu(和Debain)包含一个特别陈旧的KED3/GNOME2包叫docker,所以我们把这个包叫docker.io
