Nginx subdomain for different systems

I have an instance in google cloud that contains 2 systems 1 running on port 8000 and another on port 8080 and nginx already configured 8000 - > 80.

And I have a domain configured in the cloudflare with the following routes: myite.com and the subdomain subdomain.myusite.com

The miite.com entry for the service running on port 8000 is already working. I would like to point the subdomain to the service running on port 8080
