GeoIP integration: Location-based services

The GeoIP integration allows you load Maxmind’s GeoIP2 City database (both commercial and free versions) and enrich all KrakenD calls to your backends with geo data.

To add GeoIP information to your backends, copy the Maxmind’s database file into the filesystem (it has to be a city DB) and specify its location in the configuration. Downloading the database requires signing up to MaxMind’s website.

Configuration for GeoIP

Add the following extra_config in the root to your configuration file:

{
    "version": 3,
    "plugin": {
        "pattern":".so",
        "folder": "/opt/krakend/plugins/"
    },
    "extra_config": {
        "plugin/http-server": {
            "name": ["geoip", "another-plugin-maybe" ],
            "geoip": {
                "citydb_path": "/etc/krakend/GeoIP2-City.mmdb"
            }
        }
    }
}
