容器是可移植、可执行的轻量级的镜像，包含其中的软件及其相关依赖。

Containers decouple applications from underlying host infrastructure to make deployment easier in different cloud or OS environments, and for easier scaling.
The applications that run inside containers are called containerized applications. The process of bundling these applications and their dependencies into a container image is called containerization.

容器使应用和底层的主机基础设施解耦，降低了应用在不同云环境或者操作系统上的部署难度，便于应用扩展。
在容器内运行的应用程序称为容器化应用程序。 将这些应用程序及其依赖项捆绑到容器映像中的过程称为容器化。
