redirect nginx from port to another port and subdirectory nginx

I have a service running on: http://localhost:49159 I created an nginx docker to forward the service from port 49 to 8080 by the following

nginx.conf:
user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include mime.types;
    sendfile on;
    upstream aspnetapp {
    server 127.0.0.1:49159;

}

    server {
    listen       8080;
    resolver 127.0.0.11;
    autoindex off;
    
    server_name localhost;
    server_tokens off;

    location / {
        
       proxy_pass http://172.17.0.1:49159;
    }
}
}

so by now, I can forward all the request from http://localhost:49159 to http://localhost:8080

Now, I want to forward all the requests from http://localhost:49159 to http://localhost:8080/service/. so all the requests will be redirected to /service/ subdirectory of 8080.

Preferably, I don't want to change my service config. I hope I can make this change by changing nginx.conf
