前言 {#前言}

本来想打算部署一个memos，结果本地用docker部署的时候发现压根拉不下来。最后网上查到被墙了，使用了国内大厂的源也是一样用不了，有些人说阿里可以用，实测不行

申请域名 {#申请域名}

在 namesilo 上随便申请一个结尾是 xyz 的域名，可以使用子域名的，可以多个地方使用。可以支付宝付款 大概10元左右,比如说下面这个

cloudflare托管域名 {#cloudflare托管域名}

登录 cloudflare 添加站点 直接输入刚刚申请的域名

到第3部的时候会有两个NS的服务器值

回到 namesilo 点击右上角的头像的 My Account

再面板里面点击管理 Manage

点进去之后就可以看到购买的域名列表 点击购买的域名

点进去可以可以看到域名目前的NS，点击右边笔 把默认的全部删除 改成上面获取到的NS也就是上面的 iris.ns.cloudflare.com 和 memphis.ns.cloudflare.com ，改完后就是下面图这样

再回到 cloudflare 点击检查服务器即可，点击检查服务器之后需要等待，可以先做下面的步骤。成功之后就会收到邮件通知

创建Workers {#创建Workers}

在 cloudflare 上点击左边的Workers 和 Pages

在右边先点击创建 然后在点击创建worker

起一个记得住的名字 点击保存

保存后到下面这里 直接点击完成

点击完成后就部署成功 需要修改代码 点击编辑代码

删除默认的代码

把下面的代码粘贴到里面

修改代码 把 workers_url 改成刚刚申请的域名,比如申请的域名是 xb0.xyz 那么这里就写 https://xb0.xyz 当然也可以使用子域名 比如 https://docker.xb0.xyz

最后点击右上角的部署即可

回到设置 点击触发器 添加自定义域

填写刚刚在代码文件里面写的域名 比如填的是 https://docker.xb0.xyz 那么这里就写 docker.xb0.xyz 填写完成点击添加自定义域。等待部署完成即可

修改Docker镜像源 {#修改Docker镜像源}

我用的不是直接的Docker桌面软件，而且更小的 orbStack 可能更改方式有点区别

打开OrbStack的设置 找到Docker 直接填写刚刚定义的域名即可 默认配置里面什么都没有 不需要刻意去格式化 点击Apply的时候会自动转义和格式化

|---------------------------------------------------------------| | { "registry-mirrors" : [ "https://docker.xb0.xyz" ] } |

验证 {#验证}

安装个memos查看是否成功
