# 安装 Docker

Docker 分为 CE 和 EE 两大版本。CE 即社区版（免费，支持周期 7 个月），EE 即企业版，强调安全，付费使用，支持周期 24 个月。

Docker CE 分为 `stable` `test` 和 `nightly` 三个更新频道。每六个月发布一个 `stable` 版本 (`18.09`, `19.03`, `19.09`...)。

官方网站上有各种环境下的 [安装指南](https://docs.docker.com/install/)，这里主要介绍 Docker CE 在 `Linux` 、`Windows 10` 和 `macOS` 上的安装。
