If you have enabled the Awair Local API on your compatible Awair device, note the URL you use to view the latest air data. It should look like: http://1.2.3.4/air-data/latest. You'll need to provide that as the value for the AWAIR_LOCAL_URL environment variable when you run this code.
AWAIR_LOCAL_URL=http://1.2.3.4/air-data/latest cargo rundocker build --rm . -t awair-local
docker run -e AWAIR_LOCAL_URL=http://1.2.3.4/air-data/latest -p 9185:9185 awair-local
