ProcessMySteps

Backend for GatherMySteps

Running

The server is highly parameterable, use

python server.py --help

to get all the options.

Database access is not mandatory, however some functionalities may not work. You can set DB_NAME, DB_PASS, DB_HOST, DB_PORT and DB_NAME with environment variables. All of those must be set so that ProcessMySteps can connect with the database.

The start.sh starts a docker container with a valid database setup, and starts the server connected with it.
