How to use Docker to run app

Please stop existing mysql client running (use terminal mysqld stop OR MAC: System Preferences last row go into MySQL to turn off)

Since the Flask depends on a Mysql server, its a big overhead for users to install their own mysql servers and populate them with their own data. We created 2 containers (1 for python code, 1 for the mysqlserver) and linked them through docker-composer to be able to communicate with each other. The setup code in db/init.sql automatically populates the database with sufficient data to test and run the Flask app

1. install Docker and docker-compose for your operation system
2. cd into TradingSystem directory (one that contains docker-compose.yml)
3. Run docker-compose build then docker-compose up to set up both python and mysql containers and connect them together
4. If you make any changes to the python code, you can use ctrl-c to stop both services, run docker-compose build app to build the latest python app image docker-compose up to deploy the latest app image into a container
5. If you want to use your own python app.py which is eaiser to debug and develop in. I recommend doing only the docker-compose build db and docker-compose start db. This way you can connect to the mysql image that is in your container without having your own mysql server in your localhost. Then you can use python app.py to run your Flask app. Make sure to update your mysqlConfig.py with (host="127.0.0.1" instead)
