Despliegue ​

FastAPI se despliega normalmente con ASGI, usando Uvicorn o Gunicorn con workers Uvicorn.

Ejecucion local ​

bash
uvicorn app.main:app --reload

Produccion ​

bash
gunicorn app.main:app \
  -k uvicorn.workers.UvicornWorker \
  --bind 0.0.0.0:8000 \
  --workers 4

Dockerfile ​

dockerfile
FROM python:3.12-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
EXPOSE 8000
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8000"]

Health check ​

python
@app.get("/health")
def health():
    return {"status": "ok"}

Configuracion ​

Usa variables de entorno y pydantic-settings.

Buenas practicas ​

  • No uses --reload en produccion.
  • Configura workers segun CPU y workload.
  • Expón health checks.
  • Logs a stdout.
  • Secrets fuera del codigo.
  • Ejecuta migraciones de forma controlada.
