WAM_server_API_template

Template repository for creating API server to dispatch simulation tasks to a queue of workers. The API typically recieves a post request with a json input file, sends this file to a parser which initiate a long simulation (like oemof). Once the simulation is done a json response is sent back. The json results can also be retrieved with the task id.

Get started

Run sudo docker-compose up -d --build to run the task queue and the webapp simulaneously.

Now the webapp is available at 127.0.0.1:5001

Run sudo docker-compose down to shut the services down.
