How to deploy FlexMeasures

Here you can learn how to get FlexMeasures onto a server.


It would be great to enable Dockerization of FlexMeasures, let us know if this matters to you.

WSGI configuration

On your own computer, flexmeasures run is a nice way to start FlexMeasures. On a production web server, you want it done the WSGI way. Here is an example how to serve FlexMeasures as WSGI app:

# This file contains the WSGI configuration required to serve up your
# web application.
# It works by setting the variable 'application' to a WSGI handler of some description.

import os
from dotenv import load_dotenv

project_home = u'/path/to/your/code/flexmeasures'
load_dotenv(os.path.join(project_home, '.env'))

# create flask app - need to call it "application" for WSGI to work
from import create as create_app
application = create_app()

Keep in mind that FlexMeasures is based on Flask, so almost all knowledge on the web on how to deploy a Flask app also helps with deploying FlexMeasures.

Install the linear solver on the server

To compute schedules, FlexMeasures uses the Cbc mixed integer linear optimization solver. It is used through Pyomo, so in principle supporting a different solver would be possible.

Cbc needs to be present on the server where FlexMeasures runs, under the cbc command.

You can install it on Debian like this:

apt-get install coinor-cbc

If you can’t use the package manager on your host, the solver has to be installed from source. We provide an example script to do that, where you can also pass a directory for the installation.

In case you want to install a later version, adapt the version in the script.
