Docker v1.12.0-rc5 发布下载，高级容器引擎

Docker v1.12.0-rc5 发布下载，Docker 是 PaaS 提供商 dotCloud 开源的一个基于 LXC 的高级容器引擎，源代码托管在 Github 上, 基于go语言并遵从Apache2.0协议开源。

Docker的思想来自于集装箱，在一艘大船上，可以把货物规整的摆放起来。并且各种各样的货物被集装箱标准化了，集装箱和集装箱之间不会互相影响。那么我就不需要专门运送水果的船和专门运送化学品的船了。只要这些货物在集装箱里封装的好好的，那我就可以用一艘大船把他们都运走。

docker就是类似的理念。现在都流行云计算了，云计算就好比大货轮。docker就是集装箱。
