Atlas

Atlas is a geoip HTTP service built in Rust, designed to simplify IP GeoLocation by automatically managing MaxMind databases. It ensures that users have up-to-date IP data without the hassle of manual downloads and updates. This tool is perfect for services who need reliable and fast IP GeoLocation lookup in their applications using a very simple HTTP API.

Learn more about Atlas in my blog post here.

Features

• Automatic Database Updates: Automatically downloads and updates MaxMind's GeoIP databases.
• Dead-simple HTTP API: Atlas has a very simple HTTP API that users can use and query IP Data.
• Efficient and Low Memory Footprint: Built with Rust for safety and performance also to minimize memory footprint during database updates and normal operations.
• Configurable: Allows users to select which edition of the MaxMind databases they want to use (e.g., GeoLite2, GeoIP2, Enterprise, ISP).

Running Atlas

To run Atlas, you can choose one of the methods below.

Using Docker (Recommended)

We automatically build docker images of Atlas and push them to docker hub.

You can easily run our docker image which automatically downloads the latest MaxMind DB like this.

docker run -it --rm \
  -e "MAXMIND_ACCOUNT_ID={account id here}" \
  -e "MAXMIND_LICENSE_KEY={license_key_here}" \
  -p 8080:8080 \
  alisinabh/atlas

Same image can be used for deploying Atlas to Kubernetes or other orchestration platforms. By default, the databases will be saved at /opt/atlas/db directory. It is recommended to mount this path to a persistant storage medium to avoid downloading a new DB on every restart.

For more configuration variables, visit Configuration section.

Compiling from source

Firstly, make sure you have rustc and cargo installed. Then after cloning the repository you can simply run the following command to build a release binary to use in your service.

cargo build --release

You can find the release binaries at target/release/atlas. Then you can run atlas by running ./target/release/atlas in your terminal. Make sure that the DB_PATH directory already exists otherwise atlas crashes on startup.

API Documentation

Atlas generates OpenApi 3.0 specifications for its APIs. We host our main branch docs at https://atlas-rs.fly.dev/swagger-ui/.

You can also enable the /swagger-ui endpoint locally or in your deployments by setting SWAGGER_UI_ENABLED to true.

Configuration

Atlas uses OS environment variables for configuration. Here are the list of environment variables that atlas looks into.

• MAXMIND_ACCOUNT_ID: Your Maxmind Account ID used to download the database. Required (Get GeoLite2 databses for free at https://dev.maxmind.com/geoip/geolite2-free-geolocation-data)
• MAXMIND_LICENSE_KEY: Your Maxmind license key used to download the database. Required (Generate a License Key from maxmind portal)
• MAXMIND_DB_VARIANT: (Also called Edition ID) The database edition to used. Default is GeoLite2-City.
• MAXMIND_DB_DOWNLOAD_URL: Database download URL (only change if your download URL differs). Default is https://download.maxmind.com/geoip/databases/{VARIANT}/download?suffix=tar.gz. {VARIANT} literal will be replaced by MAXMIND_DB_VARIANT value.

• DB_PATH: Default path to save databases in. Default is /opt/atlas/db.
• DB_UPDATE_INTERVAL_SECONDS: How often to check for updates in seconds. Default is a day (86400s).
• HOST: Host to serve Atlas API on. Default is 0.0.0.0.
• PORT: Port number to serve Atlas API on. Default is 8080.
• SWAGGER_UI_ENABLED: If set to true swagger UI will be served on http://{HOST}:{PORT}/swagger-ui endpoint. Default is false.
