From Nginx subpath to root in different port

Question

I have one server with several web services exposed in different ports in docker containers.

With nginx I would like use subpaths to browse througth these servers. For example: I have Nextcloud in http://myurl:8080/ Reachable from http://myurl:80/nextcloud .

I tried different solution, probably the most closed to reach the solution is the following:

 location /nextcloud/{

    proxy_pass http://myurl:8080/;
    }

But in this way I lost the first parameter in the url: instead of proxying on http://myurl/nextcloud/a/b ; I'm proxed on http://myurl/nextcloud/b , losing /a

Answer 1

location /nagios/ {
    rewrite ^/nagios(/.*)$ $1 break;
    proxy_pass  http://10.0.21.8:80/;
    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 https;
    proxy_redirect    off;
}
