|
|
|
| 依赖包 | 作用 | 为什么需要 |
|
|
| :-------------------------------: | :-----------------------: | :-----------------------------------: |
|
|
| **yum-utils** | 添加和管理 yum 仓库 | 用于添加 Docker 官方仓库 |
|
|
| **device-mapper-persistent-data** | devicemapper 存储驱动依赖 | 保证 Docker 底层存储驱动正常运行 |
|
|
| **lvm2** | 提供逻辑卷管理工具 | devicemapper 依赖，提供底层块存储支持 |

3. 设置存储库
|
|
|
|
- 官方源
|
|
|
|
```bash

|
```
|
|
|
|

|
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
|
|
```
|
|
|
|
- 清华 TUNA Docker 源
|
|
|
|
```bash
|
|
cat > /etc/yum.repos.d/docker-ce.repo << 'EOF'
|
|
[docker-ce-stable]
|
|
name=Docker CE Stable - $basearch
|
|
baseurl=https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/$releasever/$basearch/stable
