For production builds, we'll want to have a real WSGI front end instead of the built in Flask developer web server. For time's sake, Ubuntu 18.04 instructions are provided. That said, this is a pretty generic setup and should be easily replicable to other platforms.

Gunicorn Installation

Gunicorn is a WSGI server written in Python.

Install

# pip3 install gunicorn

Configure

Locate your gunicorn executable with which gunicorn.

Permissions

Gunicorn requires read/write/executable access to the entire hyperglass/hyperglass directory in order to read its configuration and execute the python code. If running gunicorn as www-data, fix permissions with:

# chown -R www-data:www-data /opt/hyperglass/hyperglass
# chmod -R 744 /opt/hyperglass/hyperglass
