Download geo objects

This system needs the list of streets and places of a city to have a working text parser. To download the data and parse them into the database you need to execute the ./bin/download_geo_objects.s script. It will download a couple of hundred megabytes of data.

Deployment

The server is configured using ansible with this playbook and can be updated with:

ansible-playbook ansible/playbook.yml -i ansible/hosts --extra-vars '{"username": "***********"}'

Deploy is done by running:

VERSION=`git rev-parse HEAD`
make prod-build
scp build/hierbautberlin-$VERSION.tar.gz user@server:~/hierbautberlin
ssh user@server 'bash -s' < bin/deploy.sh $VERSION
