GeoIP

A simple webservice that returns the location of the user based on IP address

• Make sure pip3 is installed (https://pip.pypa.io/en/stable/installing/) and in PATH

• Add GeoLite2-City.mmdb from maxmind.com (free account required)

• Install dependencies and start the server by running make

    make run
  

Running on Amazon Lambda

• Build a deployment .zip by running

    make geoip.zip
  

• Upload the zip to an S3 bucket (it's too big to upload to Lamba directly)

• In AWS, create an empty Lamba function

• In the section for Function code, pick your S3 url, Python 3.7 or higher and set handler to lambda_function.lambda_handler (the default)

You can add a test event in the console with the following JSON, you can choose a different IP address

{"requestContext":{"http":{"sourceIp":"158.38.0.1"}}}
