UI for Docker with Nginx HTTP Auth

Note: The examples/nginx-basic-auth directory contains a complete example using docker-compose.

---

First add the upstream conf to your nginx configuration :

upstream ui_for_docker {
    server 172.17.42.1:9000;
}

Then here the sample vhost configuration :

server {
        listen 80;
        server_name uifd.example.com;

        access_log /var/log/nginx/uifd.access.log main;
        error_log /var/log/nginx/uifd.error.log info;

        location / {
 

                #basic auth
                auth_basic            "UI for Docker";
                auth_basic_user_file  /somewhere.htpasswd;

                proxy_pass http://ui_for_docker;
                #http 1.1 support...
                proxy_http_version 1.1;
                proxy_set_header Connection "";

                proxy_redirect     off;
                proxy_set_header   Host $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-Host $server_name;

        }
        root /home/johndoe/www/;
}

Note the explicit proxy_http_version 1.1 and proxy_set_header Connection "";. By default nginx use http 1.0. Without these settings, you get HTTP 500 errors.
