Deployment to Production

This app is containerized and intended to be deployed in a Docker. This means you can deploy it anywhere from fully managed PaaS services to container hosting services and custom self-hosted solutions.

The Dockerfile will install the dependencies from the requirements.txt in the container and will run Flask with Gunicorn. Depending on your traffic and server resources, you will want to adjust the number of workers in the Dockerfile.

For reference, the live demo website is running on a cheap VPS with CapRover installed. CapRover is a self-hosted PaaS built as a layer on Docker. It simplifies setting environment variables, routing traffic to containers nginx reverse proxy, and SSL set up. I use this GitHub Actions workflow for continuous deployment.

Here is a Medium article I wrote about configuring a server instance with CapRover.
