  order geo_ip first
}

localhost:8080 {

  geo_ip {
    db_path GeoLite2-Country.mmdb
    trust_header X-Real-IP

Configuration

account - this is the Maxmind Account, required for all download operations. Can be supplied as an ENV Variable GEO_ACCOUNT_ID.

db_path - is the path to load the database from. The filename is used to determine the edition of the file to download Valid values tested with are GeoIP2-Country | GeoLite2-Country

trust_header - this is used to determine the header to load the users ip address from, if empty it will use the requests RemoteAddr

api_key - this is a Maxmind API Key. If blank no attempt will be made to download the database. Can be supplied as an ENV Variable GEO_API_KEY.

download_frequency - this is how often to download the database from the Maxmind Server (requires an APIKey)

reload_frequency - this is how often to check for updated versions of the database on disk. This can be used when an external process is responsible for downloading the database. If the database is being managed via the api_key and download_frequency then there is no need to specify the reload_frequency

override_country_code - this setting allows for the country code to be configured for local development. It will attempt to use the database if there is one, and use the value if no record could be found.
