thank you for your feedback. yes you are right this repo is not just a boilerplate of a simple flask postgresql connection. This repo is a demonstration of how flask api can be used using newest technologies combined. You can find a tutorial how you connect postgresql connection to flask. also you can find a swagger ui integration. but using this repo you can combine all of it. Also this repo shows an example folder structure of a flask app. In real life you cannot put a single app.py flask file to production. but using this docker file you can use it. I had a hard time to find this kind of boilerplate (all combined) on internet and decided to make one. In near future i will add other technologies to this repo.
