# Docker

## 自动安装方式

Docker 提供了一个自动配置与安装的脚本，支持 Debian、RHEL、SUSE 系列及衍生系统的安装。
**请注意**，Docker 官方不建议在生产环境使用此脚本安装 Docker CE。

1. 设置环境

    ```bash
    export DOWNLOAD_URL="https://mirrors.tuna.tsinghua.edu.cn/docker-ce"
    ```

2. 下载安装脚本

    使用 curl

    ```bash
    curl -fsSL https://i.sugarscat.cn/me/script/-/raw/main/docker/install.sh | sh
    ```

    使用 wget

    ```bash
    wget -O- https://i.sugarscat.cn/me/script/-/raw/main/docker/install.sh | sh
    ```

## Debian/Ubuntu/Raspbian

> 以下内容根据[官方文档](https://docs.docker.com/engine/install/debian/)修改而来。

如果你过去安装过 docker，先删掉：

```bash
for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do apt-get remove $pkg; dones
```

首先安装依赖：

```bash
apt-get update
apt-get install ca-certificates curl gnupg
```

信任 Docker 的 GPG 公钥并添加仓库：

- 发行版 Debian

  - 清华源

     ```bash
     install -m 0755 -d /etc/apt/keyrings
     curl -fsSL https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
     sudo chmod a+r /etc/apt/keyrings/docker.gpg
     echo \
       "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian \
       "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
       tee /etc/apt/sources.list.d/docker.list > /dev/null
     ```

  - 阿里云源

     ```bash
     install -m 0755 -d /etc/apt/keyrings
     curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
     sudo chmod a+r /etc/apt/keyrings/docker.gpg
     echo \
       "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/debian \
       "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
       tee /etc/apt/sources.list.d/docker.list > /dev/null
     ```

- 发行版 Ubuntu

  - 清华源

     ```bash
     install -m 0755 -d /etc/apt/keyrings
     curl -fsSL https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
     sudo chmod a+r /etc/apt/keyrings/docker.gpg
     echo \
       "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu \
       "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
       tee /etc/apt/sources.list.d/docker.list > /dev/null
     ```

  - 阿里云源
  
      ```bash
     install -m 0755 -d /etc/apt/keyrings
     curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
     sudo chmod a+r /etc/apt/keyrings/docker.gpg
     echo \
       "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \
       "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
       tee /etc/apt/sources.list.d/docker.list > /dev/null
     ```

- 发行版 Raspbian

  - 清华源

     ```bash
     install -m 0755 -d /etc/apt/keyrings
     curl -fsSL https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/raspbian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
     sudo chmod a+r /etc/apt/keyrings/docker.gpg
     echo \
       "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/raspbian \
       "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
       tee /etc/apt/sources.list.d/docker.list > /dev/null
     ```
    
  - 阿里云源

     ```bash
     install -m 0755 -d /etc/apt/keyrings
     curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/raspbian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
     sudo chmod a+r /etc/apt/keyrings/docker.gpg
     echo \
       "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/raspbian \
       "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
       tee /etc/apt/sources.list.d/docker.list > /dev/null
     ```

apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
```

## Fedora

如果你之前安装过 docker，请先删掉

```bash
dnf remove docker \
         docker-client \
         docker-client-latest \
         docker-common \
         docker-latest \
         docker-latest-logrotate \
         docker-logrotate \
         docker-selinux \
         docker-engine-selinux \
         docker-engine
```

安装依赖，下载 repo 文件，并把软件仓库地址替换为镜像站：

- 清华源

   ```bash
   dnf -y install dnf-plugins-core
   dnf config-manager --add-repo https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/fedora/docker-ce.repo
   sed -i 's+https://download.docker.com+https://mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo
   ```
  
- 阿里云源

   ```bash
   dnf -y install dnf-plugins-core
   dnf config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/fedora/docker-ce.repo
   sed -i 's+https://download.docker.com+https://mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
   ```

最后安装：

```bash
dnf install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
```
