+
+**注意: 本镜像只提供 Debian/Ubuntu/Fedora/CentOS/RHEL 的 docker 软件包，非 dockerhub**
+
+
+### Debian/Ubuntu 用户
+
+以下内容根据 [官方文档](https://docs.docker.com/engine/installation/linux/docker-ce/debian/) 修改而来。
+
+如果你过去安装过 docker，先删掉:
+
+```bash
+sudo apt-get remove docker docker-engine docker.io
+```
+
+首先安装依赖:
+
+```bash
+sudo apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common
+```
+
+信任 Docker 的 GPG 公钥:
+
+```bash
+curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
+```
+
+对于 amd64 架构的计算机，添加软件仓库:
+
+```bash
+sudo add-apt-repository \
+ "deb [arch=amd64] https://download.docker.com/linux/debian \
+ $(lsb_release -cs) \
+ stable"
+```
+
+如果你是树莓派或其它ARM架构计算机，请运行:
+
+```bash
+echo "deb [arch=armhf] https://download.docker.com/linux/debian \
+ $(lsb_release -cs) stable" | \
+ sudo tee /etc/apt/sources.list.d/docker.list
+```
+
+最后安装
+
+```bash
+sudo apt-get update
+sudo apt-get install docker-ce
+```
+
+### Fedora/CentOS/RHEL
+
+以下内容根据 [官方文档](https://docs.docker.com/engine/installation/linux/docker-ce/centos/) 修改而来。
+
+如果你之前安装过 docker，请先删掉
+
+```bash
+sudo yum remove docker docker-common docker-selinux docker-engine
+```
+
+安装一些依赖
+
+```bash
+sudo yum install -y yum-utils device-mapper-persistent-data lvm2
+```
+
+
+
+
+
+
+
+
+
+把软件仓库地址替换为 TUNA:
+
+```bash
+sudo sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo
+```
+
+最后安装:
+
+```bash
+sudo yum makecache fast
+sudo yum install docker-ce
+```
