高級容器引擎 Docker v1.12.2-rc1發布

 

     Docker 是 PaaS 提供商 dotCloud 開源的一個基于 LXC 的高級容器引擎，源代碼托管在 Github 上, 基于go語言并遵從Apache2.0協議開源。Docker的思想來自于集裝箱，在一艘大船上，可以把貨物規整的擺放起來。并且各種各樣的貨物被集裝箱標準化了，集裝箱和集裝箱之間不會互相影響。那么我就不需要專門運送水果的船和專門運送化學品的船了。只要這些貨物在集裝箱里封裝的好好的，那我就可以用一艘大船把他們都運走。docker就是類似的理念。現在都流行云計算了，云計算就好比大貨輪。docker就是集裝箱。
