OpenWrt 怎么安装 Docker 并启动

1. 概述

Docker 是一种轻量级的容器化技术，允许开发者在隔离的环境中运行应用程序。OpenWrt 是一个基于 Linux 的开源路由器操作系统，通常用于嵌入式设备。虽然 OpenWrt 主要用于路由器，但通过安装 Docker，你可以在 OpenWrt 设备上运行各种容器化应用，从而扩展其功能。

本文将详细介绍如何在 OpenWrt 上安装 Docker 并启动容器。我们将从准备工作开始，逐步引导你完成整个过程。

2. 准备工作

在开始之前，请确保你的 OpenWrt 设备满足以下要求：

• 硬件要求：OpenWrt 设备需要具有足够的存储空间和内存来运行 Docker。建议至少 512MB 的 RAM 和 1GB 的存储空间。
• 软件要求：OpenWrt 版本应为 19.07 或更高版本，以确保支持 Docker。
• 网络连接：确保设备已连接到互联网，以便下载必要的软件包。

3. 安装 Docker

3.1 更新软件包列表

首先，通过 SSH 登录到你的 OpenWrt 设备。然后，更新软件包列表以确保你获取到最新的软件包信息。

opkg update

3.2 安装 Docker 依赖

Docker 依赖于一些额外的软件包。在安装 Docker 之前，需要先安装这些依赖。
