🔙Reverse Proxy

Running a reverse proxy in front of pupcloud is almost mandatory if you want to expose it on the internet. More than that, there are a number of reverse proxies that allow you to protect a http connection with https, using a free certificate provided for example by Let's Encrypt or similar.

We'll show here how to integrate with two popular solutions, Caddy and NGINX.

Caddy

To access pupcloud from (e.g.) https://pupcloud.test.com:

1. Expose ports 80 and 443 of the server to which the DNS points;

2. Run pupcloud. Leave the port as 17178;

3. Launch caddy: sudo caddy reverse-proxy --from pupcloud.test.com --to localhost:17178

You'll need to launch caddy with root/admin privileges, as it must access privileged ports.

NGINX

NGINX is quite complex to configure, and it's beyond the scope of this document. Usually, we make use of LinuxServer's Swag Docker image, paired with pupcloud's own docker image. The relevant config is in nginx/site-confs/default:

server {
        listen 443 ssl http2;
        server_name pupcloud.test.com;
        include /config/nginx/proxy-confs/*.subfolder.conf;
        include /config/nginx/ssl.conf;
        location / {
                proxy_pass http://localhost:17178/;
        }
}
