Configuring nginx to map pgadmin to a URI - nginx

Question

I have an nginx and a pgadmin Docker container connected to each other. Only nginx container is exposed to the outside. How can I map pgadmin to a sub URI?
If the host is example.com, I want the pgadmin to be reachable at example.com/pgadmin/. So far, I have this in my nginx.conf file:
location ^~ /pgadmin/ {
proxy_set_header Host $http_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 $scheme;
proxy_pass http://pgadmin:80/;
}
A request to example.com/pgadmin/ goes through to pgadmin but when pgadmin redirects to the login page, it redirects to example.com/login?next=%2F, not to example.com/pgadmin/login?next=%2F.
How can I make pgadmin to work at example.com/pgadmin?

I understand that you want to map http://pgadmin:80/ to http://example.com/pgadmin/.
Add the below entry in your hosts file to map pgadmin to example.com
pgadmin example.com
Now to map the :80 to /pgadmin, add the following in your nginx.conf :
location /pgadmin {
proxy_set_header Host $http_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 $scheme;
proxy_pass http://pgadmin:80/;
}
