Epimetheus backend server

Python server that connects to database and provides data for frontend.

Database

Currently, the only supported database engine is PostgreSQL. It can be local or cloud version.

The database should also be initialized, and some results archived before the backend server can start serving data.

First make sure you have python and pip installed.

Install required pip packages:

pip install -r .\requirements.txt

Start python server with environment variables:

python .\server.py --database dbname --host dbhost --user dbuser --pw dbpasswd --port 5000

That's it. Server should be running at http://localhost:5000.

If you want to use other port than 5000, set it with --port parameter. Note that you should also tell frontend to use non-default port.

Use the provided Dockerfile to run python server in a container.

Docker environment should contain values for following parameters:

DATABASE: database name
HOST: database host
USER: database user
PASSWORD: database password
PORT: server port

Backend API has swagger documentation available, and it can be viewed at localhost:5000/data/doc/ (with direct access to backend) or proxied through frontend server localhost:3000/data/doc/. It uses tornado-swagger.

Documentation is located in server.py.

If you do modify the API, please update the related swagger documentation as well. That makes it easier for everyone to develop new features.
