Process Container）的轻量 级VM解决方案。 Docker Docker的初衷是将各种应用程序和他们所依赖的运行环境打包成标准的container/image，进 而发布到不同的平台上运行。 Docker Why Docker？ n 应用环境管理复杂 n 云计算时代的到来 n 虚拟化手段的变化 n LXC的便携性 Docker Docker Container和普通的 在LXC的基础上，Docker额外提供的特性包括： n 标准统一的打包部署运行方案 n 历史版本控制 n Image的重用和共享发布等 Growing Docker 例如，百度的BAE平台的PaaS服务由Docker支持。 Technologies in Docker Docker是一个操作系统级的、容器化的虚拟化方法。 隔离性 Linux Namespace (NS) pid namespace 的实现方式变成了一种可变的方案，无论是使用namespace、cgroups技术抑或是使用 systemd等其他方案，只要实现了Libcontainer定义的一组接口，Docker都可以运行。这也为 Docker实现全面的跨平台带来了可能。 Libcontainer是Docker中用于容器管理的包，基于Go语言实现，通过管理namespaces、 cgroups、capabilities以及文件系统来进行容器控制。可以使
