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

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

4eb0ce17-86fa-43ff-bff5-a9112b0ec87e

cloudflare托管域名

登录cloudflare添加站点 直接输入刚刚申请的域名

18f86492-3f92-4893-866a-28e94ee69d61

到第3部的时候会有两个NS的服务器值

9704d602-43a7-48fe-b664-f46b1281dc71

回到namesilo点击右上角的头像的My Account

8a41e033-06d2-4637-9fdf-88220fb93c95

再面板里面点击管理Manage

6ab6284e-a6e2-42e1-95ab-903e99a7f40f

点进去之后就可以看到购买的域名列表 点击购买的域名

056627e5-cb44-4b2c-9b4a-2cb2d4cc70d5

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.commemphis.ns.cloudflare.com,改完后就是下面图这样

7038282d-3053-4119-8326-33b4a464ae51

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

ea475cea-89db-4209-9f29-c80d0b95118e

创建Workers

cloudflare上点击左边的Workers 和 Pages

30d3e37b-a0e1-46e8-bc93-b38a3d65a4bf

在右边先点击创建 然后在点击创建worker

fb841094-7daa-41b6-851e-6049218e5643

起一个记得住的名字 点击保存

b9e9d173-11a8-44ac-acf8-f8e0b63ee03e

保存后到下面这里 直接点击完成

26ae987f-51c5-4490-8927-8d6dad68cd92

点击完成后就部署成功 需要修改代码 点击编辑代码

eb34fecf-51e2-4559-833d-2eebe949160f

删除默认的代码

6724f75c-c10f-4b74-af29-44bb44fc770e

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

4fc53365-392b-492f-b744-9fa00c5bfb5d

最后点击右上角的部署即可

35ef1666-5762-4357-b66c-1e909befb3da

回到设置 点击触发器 添加自定义域

df7c0436-ff26-4283-a89f-4cc3cb677e4e

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

26956331-39c6-4dbf-b344-bd981322db5a

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

安装个memos查看是否成功
