Dockerize full service with docker-compose

[AimelHassan]

Production deployment should be a single docker-compose up.

Services to containerize:

• FastAPI middleware service
• PostgreSQL for audit logging
• Redis for caching and token mapping

Include example .env file and basic health checks.

I've implemented a solution for this issue.

Repository: https://github.com/ashike24/pii-safe-docker

What's included:

• docker-compose.yml — single command spins up FastAPI + PostgreSQL + Redis + Nginx
• Multi-stage Dockerfile (dev with hot-reload, production with gunicorn)
• .env.example with all environment variables documented
• Health checks on all three services (API, Postgres, Redis)
• Redis for session token map caching with configurable TTL
• PostgreSQL for structured audit log persistence
• Nginx reverse proxy with rate limiting (30 req/s)
• 22 integration tests passing (no live containers needed)
