Node.js proxy with nginx

This might be a similar question to this one (Node.JS proxy with Nginx and Docker) but with some small difference. I want to run nginx directly on host and proxy-pass to a docker container running Nodejs.

This is the configuration block.

    location /nodejs {
            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 $scheme;
            proxy_pass http://172.17.0.2:3000;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
    }

I have nodejs container running at 172.17.0.2 with expose port on 3000. But using address "host_ip/nodejs" doesn't seem to forward correctly. Because if I do host port mapping, then "host_ip:3000" redirects to a login page "./login" which is correct. But "host_ip/nodejs" redirects only to "/".

This is the test using curl.

$ curl host_ip:3000
Found. Redirecting to ./login/

$ curl host_ip/nodejs
See Other. Redirecting to /

If I want to let "host_ip/nodejs" have the same effect as "host_ip:3000", what I have to do?

Thanks.
