Use docker-compose

Start docker-compose

$ docker-compose up --force-recreate --build 

Will run four containers:

api  - python Flask API
postgres  - DB postgreSQL 
broker    - kafka-broker
zookeeper - zookeeper for kafka-broker

For postgres will also execute pgconfig/init_db.sql. The script contains Schema of DB recommendation with small sample data.

Produce data from Different source example

In file "api/produce_data_test.py" I add example of extract and load data into kafka-topic.

Usage API service

#### Default token auth
$ -H 'Authorization: Token tokenTest1'

#### Get 10 Recommendations for current user
$ curl http://localhost:5000/get_for_current_user -H 'Authorization: Token tokenTest1'
