# APT 仓库配置
|
||
|
||
## Definition
|
||
APT (Advanced Package Tool) 仓库是 Ubuntu/Debian 系统的软件包来源，通过配置文件指定软件包的下载位置和签名验证方式。
|
||
|
||
## Docker 官方仓库配置流程
|
||
1. 安装 HTTPS 传输依赖：`sudo apt-get install ca-certificates curl`
|
||
2. 创建密钥目录：`sudo install -m 0755 -d /etc/apt/keyrings`
|
||
3. 下载并导入 GPG 密钥
|
||
4. 添加仓库源文件到 `/etc/apt/sources.list.d/`
|
||
|
||
## 配置文件位置
|
||
| 路径 | 作用 |
|
||
|------|------|
|
||
| `/etc/apt/sources.list` | 系统主仓库配置 |
|
||
| `/etc/apt/sources.list.d/*.list` | 第三方仓库配置 |
|
||
| `/etc/apt/keyrings/` | GPG 密钥存储目录 |
|
||
|
||
## Docker 仓库源文件示例
|
||
```bash
|
||
echo \
|
||
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
|
||
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
|
||
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
|
||
```
|
||
|
||
## Key Concepts
|
||
- **架构变量** `$(dpkg --print-architecture)`：自动适配 amd64/arm64 等架构
|
||
- **版本代号** `$VERSION_CODENAME`：Ubuntu 版本代号（如 jammy、noble）
|
||
- **签名验证** `signed-by`：指定 GPG 密钥路径
