DBIP Docker mod for Nginx based images

This mod downloads the dbip-country-lite.mmdb database under /config/geoip2db, the database is updated weekly.

This mod should not be enabled together with swag-maxmind or swag-ipinfo mods.

Follow these steps to enable the dbip mod:

1. In the container's docker arguments, set an environment variable DOCKER_MODS=linuxserver/mods:swag-dbip

   If adding multiple mods, enter them in an array separated by |, such as DOCKER_MODS=linuxserver/mods:swag-dbip|linuxserver/mods:swag-mod2

2. Recreate the container to apply the changes.

3. Add the following line to /config/nginx/nginx.conf under the http section:

   include /config/nginx/dbip.conf;
   

4. Edit /config/nginx/dbip.conf and add countries to the blocklist / whitelist according to the comments, for example:

   map $geoip2_data_country_iso_code $geo-whitelist {
       default no;
       UK yes;
   }
   
   map $geoip2_data_country_iso_code $geo-blacklist {
       default yes;
       US no;
   }
   

5. Use the definitions in the following way:

    server {
        listen 443 ssl;
        listen [::]:443 ssl;
   
        server_name some-app.*;
        include /config/nginx/ssl.conf;
        client_max_body_size 0;
   
        if ($lan-ip = yes) { set $geo-whitelist yes; }
        if ($geo-whitelist = no) { return 404; }
   
        location / {
   

   Or for blacklist with both some countries and continents:

   server {
       listen 443 ssl;
       listen [::]:443 ssl;
   
       server_name some-app.*;
       include /config/nginx/ssl.conf;
       client_max_body_size 0;
   
       if ($lan-ip = yes) { set $geo-blacklist yes; }
       if ($geo-blacklist = no) { return 404; }
       if ($continent-blacklist = no) { return 404; }
   
       location / {
   

6. Restart the container to apply the changes.
