How to point a Cloudflare Domain to a subfolder on DigitalOcean's App Platform

Hi there,

A quick way to achieve this would be to use a $4 Droplet with Nginx and setup your proxy rules on there, eg:

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://app-name.ondigitalocean.app/website1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

That way you can point your DNS to the Droplet’s IP address and you can add as many domains as you need.

Instead of a Droplet, you might be able to achieve this with a Dockerfile and a service deployed on the App Platform:

https://docs.digitalocean.com/products/app-platform/reference/dockerfile/

But what I would personally advise you here is to just have two separate apps for each project. That way you can take advantage of the native App Platform routing and domain mapping instead of having to manage a separate reverse proxy service.

Is there a specific reason or a limitation why you need the two sites deployed under the same app instead of separate ones?

Best,

Bobby
