How to deploy a Flask application to production?

Question

Flask

Hello.
The essence of the problem - there is an application written in Flask, acting as a rest api backend for a web application written in JS. SQLite is used as a database.
Tell me the procedure for deploying a backend to production. The application itself is not complex (that's why Flask was chosen), but I would like more uptime. Initially it will be deployed on Raspberry, then, perhaps, somewhere in the cloud hosting..

Thanks in advance.

Answer 1

I use nginx + uwsgi + flask.
uwsgi with supervisor as www-data, code in /var/www/_site_name_.
To avoid unpleasant incidents, I do this using a set of simple Ansible scripts:
I check the code and scripts on a virtual machine with Vagrant.
It sounds scary, but it’s quite convenient and easy to remember after a break.
Surely there are easier ways :)
