This repo can build a Docker image that would run MaxMind's geoipupdate command to create a geoip file at a specified mounted directory with any given GeoIP config, e.g.
Given that you have the following config stored in ~/GeoIP.conf:
UserId your_id
LicenseKey your_key
ProductIds GeoIP2-Country
You can execute the following docker command to create/update your GeoIP2-Country MMDB file:
docker run --rm -v $(pwd):/geodata -v $(pwd)/GeoIP.conf:/etc/conf/GeoIP.conf garukun/geoipupdate /etc/conf/GeoIP.conf
This will create a GeoIP2-Country.mmdb file in your working directory.
