User Management System with FastAPI

This is a simple user management system built with FastAPI, PostgreSQL, and Redis. It allows you to create users, upload avatar images, and cache user data.

What it does

• Create users with names, emails, and optional avatar images
• List all users with their avatars
• Cache user data in Redis for faster access
• Store user data in PostgreSQL
• Runs in Docker containers

Tech used

• Python with FastAPI
• SQLAlchemy for ORM
• PostgreSQL
• Redis
• Docker + Docker Compose
• Jinja2 for templates

How it’s organized

• app/crud.py – contains the database operations and caching logic
• app/db.py – sets up the PostgreSQL connection
• app/models.py – defines the User model
• app/templates/users.html – contains the Jinja2 template for the user interface
• docker-compose.yml – runs everything in containers
• Dockerfile – builds the Python app container
• requirements.txt – lists the Python dependencies

How to run it

To run the app locally:

docker-compose up --build

Docker Compose sets up three services:

• The web app (FastAPI)
• PostgreSQL
• Redis

The app will be available at http://localhost:8000.

Deployment on Hostim.dev

This app is also set up for easy deployment on Hostim.dev. It shows how to spin up a full stack app with a database and cache inside containers.
