Simple REST API built in Python with Django and DRF.

Gives ability to upload images, that later can be downloaded as:

• original files
• resized thumbnails
• can be converted to binary images (black/white) and served as binary data for specified time

Possibilities are depending on users tier, there are some built-in tiers. Admins can also create new tiers and specify ability to download binary/original files or choose custom thumbnail sizes.

I decided to make API available only for logged-in users and make uploaded photos available only for their owners (used X-SendFile for that). Structure of media links is also hidden behind randomly generated UUIDs. Thumbnails are generated on the upload (for performance - nginx could manage file serving).

Used containers:

• python (running API with gunicorn)
• nginx (proxy server, serving images and static files)
• postgres (DB)
• redis (caching - I decided to use caching with TTL to generate expiring links to binary images)

Creating the thing took me about 2 days(didn't count how much exactly, but I assume that it was about 15-20 hours), most of the time was consumed by coding and trying new things (3/4 of the time I would say). Rest of the time was spent on writing tests, configuring docker and nginx.

Project can be started using docker-compose up in main folder. There's ready .env file with some default data. Passwords and login data should probably be changed, but I left them to make starting project easier. Project starts at port 80, but It can be changed in docker-compose.yaml file. Admin panel is available at /admin, it's the easiest way to log-in using default credentials. Informations necessary to log in to admin panel (and to the browsable API in the browser) are SUPERUSER_NAME and SUPERUSER_PASSWORD from .env file.
