就我们的目的而言，可以将
Docker
容器视为一个独立的（“容器化的”）文件系统，
其中包括操作系统（例如，一个服务器版的
Ubuntu 20.04 LTS
），一个（
Python
）
运行时环境，附加系统和开发工具，以及进一步的一些（
Python
）库和程序包。这
样的一个
Docker
容器可以运行在
Windows 10 Professional 64
位的本地计算机上，
也可以运行在
Linux
操作系统的云实例上。
本节将深入介绍
Docker
容器中激动人心的细节，简要说明
Docker
技术在

镜像和容器
在继续解释之前，需要区分两个
Docker
基本术语。第一个是
Docker
镜像，可以将
其与
Python
类进行比较。第二个是
Docker
容器，可以将其与相应
Python
类的实例
进行比较。
从更技术的层面上，你将在
Docker
词汇表（

）中找到以下有
关
Docker
镜像的定义：
Docker
镜像是容器的基础。镜像是根文件系统更改和容器运行时使用的执行参
数的有序集合。镜像通常包含一个堆叠在一起的分层文件系统的并集。镜像没
有状态，并且永远不会改变。
类似地，你将在
Docker
词汇表（
https://oreil.ly/NNUiB
）中找到
Docker
容器的以下
定义，该定义使得对
Python
类和类实例的对比变得更浅显易懂：
一个容器是一个
Docker
镜像的运行时实例。
一个
Docker
容器由以下部分组成：
