Python file upload service

In the response, specify clear deadlines and budget

🚀 Goal

Develop a Docker microservice that:

• Accepts files via HTTP POST requests (up to 2 GB)
• Streams files directly into a S3-compatible storage
• Returns the path to the uploaded file (S3 path)
• Runs behind NGINX with SSL (Let's Encrypt via Certbot)
• Supports multi-threaded uploads
• Supports long connections during upload

📦 Functionality

1. Upload endpoint
   • POST /upload
   • Accepts one file via multipart/form-data
   • Required request or body parameters:
     • bucket: bucket name
     • access_key, secret_key: S3 access credentials
     • region: region
     • endpoint_url: address of S3-compatible storage
   • Uploading must use multipart upload
   • The service must not store the file locally, only stream it
   • File name should be changed to uuid
   • Extension must remain original
   • Only allowed to upload: mp3, wav, mp4, mp4a
   • Response:
     { "status": "success", "path": "s3://bucket-name/uploads/uuid.ext", "original_name": "original_name.mp4" }
2. Performance
   • Support for parallel uploads
   • No need to load entire file into memory
3. Support for long connections
   • Connection must remain open during upload
   • Proper handling of timeouts at application and proxy level
   • Timeout - 180 seconds

🐳 Deployment and containerization

1. Application container
   • Use FastAPI (Python) or another async-supporting framework
   • Listen on port 8000
2. NGINX as proxy
   • Must:
     • Proxy traffic to the application
     • Support HTTPS via Let's Encrypt (Certbot)
     • Be configured to accept files up to 2 GB
     • Not buffer request bodies
3. Docker Compose
   • Include:
     • app — microservice
     • nginx — proxy with certbot support
     • certbot — automatic certificate renewal

📁 Deliverables

• Dockerfile for the application
• The application code itself with all dependencies
• NGINX configuration with certbot support
• docker-compose.yml with all services
• Sample .env file
• README.md with setup instructions
• Sample curl request
• Comments in code, readable and understandable code

       •    File upload must be implemented via multipart upload using S3 SDK (e.g., boto3)
