 | `NGINX_REAL_IP_RECURSIVE` | set to `on` if docker container runs behind a reverse proxy,you may not want the IP address of the proxy to show up as the client address. `off` by default. |
 | `NGINX_REAL_IP_TRUSTED_ADDRESSES` | You can have NGINX look for a different address to use by adding your reverse proxy to the `NGINX_REAL_IP_TRUSTED_ADDRESSES`. Currently only a single entry is permitted. No defaults. |
+| `NGINX_CUSTOM_GITLAB_SERVER_CONFIG` | Advanced configuration option. You can add custom configuration for nginx as you like (e.g. custom location proxy). This is similar to setting `nginx['custom_gitlab_server_config']` to `gitlab.rb` for gitlab-omnibus. No defaults. |
