cf反代Docker安装源与Docker Hub镜像源

由于GFW已将docker的安装源与镜像源屏蔽，现在国内无法使用各大厂的镜像
同时本文提供docker安装方法

CloudFalre(cf)

使用worker (opens new window)编辑反代代码，将docker的安装源与Docker Hub的镜像源反代到自定义域名上

准备工作

需要准备的东西

• Cloudfalre账户 (opens new window)
• 一个域名[广告位]
• 一个键盘用于ctrl c v
• 创建好的cf worker实例

Docker 安装源反代代码

可以创建一个自定义域或使用路由

• 域: dockerinstaller.yourdomain.com
• 路由: dockerimstaller.yourdomain.com/installer 反代代码

• docker hub的镜像源使用方法
  • 修改文件/etc/docker/daemon.json中的registry-mirrors为你的反代域或路由如https://docker.yourdomain.com
  • 如果你没有上述文件，可以创建一个并将下列内容粘贴至文件内，且修改url为自己的镜像

{
    "registry-mirrors": ["https://docker.yourdomain.com"]
}

Docker安装

如果不想听我bb，这里有原文 (opens new window)
安装以操作系统Debian为例，如果你是其他系统可以使用对应的包管理器命令安装
安装依赖

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl

赋权、写gpg,将download.docker.com改为你自己的反代域名/路由

sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

写入镜像源，请将源内的域名改为你自己的反代域名/路由

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
&& sudo apt-get update

安装docker

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