Using Docker is Super Easy once it's installed, you just need to run the following commands:
cd /path/to/api
docker-compose up --build
Once the API is up and running you can access a local URL via:
http://localhost:5000/v1/geolocation/zipcode/10001?apikey=7E07D864-209A-F9E4-819F-2DD7E76B6F24&pretty
The default API Key for Development is 7E07D864-209A-F9E4-819F-2DD7E76B6F24
so you can just append ?apikey=7E07D864-209A-F9E4-819F-2DD7E76B6F24
to any API endpoint for authentication.
