nginx rewrite url without causing redirect and proxy to backend app

Question

I'm trying to achieve the below in nginx:

Hit nginx on http://<nginx-host>:81/admin/metrics and have nginx proxy it to http://127.0.0.1:8001 with the /admin/metrics rewritten to /metrics. The actual proxied admin app would receive http://127.0.0.1:8001/metrics.

So, http://<nginx-host>:81/admin/metrics => http://127.0.0.1:8001/metrics, and without causing a redirect.

This is what I have so far:

#admin app
upstream admin_backend {
    server 127.0.0.1:8001;
    keepalive 16;
}

#host /admin paths on another port
server {
  listen 81;

  #pass everything to backend admin app that matches /admin/* with /admin/ removed
  location ~ /admin/ {
    limit_except GET HEAD POST PUT { }

    proxy_set_header Host $host;
    proxy_http_version  1.1;
    proxy_pass http://admin_backend;

    rewrite ^/admin/(.*)$ /$1 last;
  }
}

This is not working. nginx is not proxying the request back to the admin app and keeps returning a 404.

What am I missing here?

I cross-posted this question on the nginx users forum, and got a solution from nanaya (thank you!).

Basically, all I needed to do was replace last with break in the rewrite directive:

So,

rewrite ^/admin/(.*)$ /$1 last;

became

rewrite ^/admin/(.*)$ /$1 break;

redirect api and files request to backend

location ~ /api/ {
    proxy_set_header    X-Forwarded-Host    $host;
    proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
    proxy_pass http://server:8009;
    rewrite ^/api/(.*)$ /$1 break;
}
