<p style="text-align: center;"><img alt="" src="https://simg.open-open.com/show/d2f43c169b53d4d2dcd40dd8a8099b7c.png" /></p> <p>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。<img
