Docker security

[matteoventuri7]

Hi, i have deployed nginx-ui on Docker like documentation but i have a problem: if I try to access to nginx-ui through nginx proxy all is ok (basic auth ask me login) but if i go direct on port 8080 then i can access to nginx-ui bypassing nginx proxy.
So, this is a summary:
nginx.mysite.com -> asking login (OK!!!)
mysite.com:8080 -> i can access to nginx-ui without login.

Any helps?
NGINX config

server { 
 listen 80;
 server_name nginx.mysite.com; 
 return 301 https://$host$request_uri; 
} 
server {
    listen 443 ssl; 
    server_name nginx.mysite.com; 
    ssl_certificate /etc/letsencrypt/live/mysite.com/fullchain.pem; 
    ssl_certificate_key /etc/letsencrypt/live/mysite.com/privkey.pem; 
    include /etc/letsencrypt/options-ssl-nginx.conf; 
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

    location / {
        proxy_pass http://127.0.0.1:8080/;
    }

    auth_basic "nginxui secured";
    auth_basic_user_file /etc/apache2/.htpasswd;
}

So, if you expose the nginx only on port 443, it wont be able to use port 8080.
If you only use this on the lan, then auth is almost obsolete
