## Overview

This repository provides a small Flask HTTP app plus a Docker Compose setup for running Flask and Nginx. The principal workflow is an HTTP client requesting `/` or `/items` from the Flask app and receiving a text or JSON response. The README documents Nginx as a separate service on the shared network, but the sampled files do not show whether its configuration forwards requests to Flask; that connection is therefore omitted.

Main entry points: [`app.py`](https://github.com/aldinkapetanovic/dockerized-flask-app/blob/main/app.py) (Flask application), [`docker-compose.yml`](https://github.com/aldinkapetanovic/dockerized-flask-app/blob/main/docker-compose.yml) (Compose services), [`nginx.conf`](https://github.com/aldinkapetanovic/dockerized-flask-app/blob/main/nginx.conf) (Nginx service)
