Troubleshooting Common Issues in Tiangolo Uvicorn-Gunicorn-FastAPI-Docker
Tiangolo Uvicorn-Gunicorn is a pre-configured setup for running web applications using the Uvicorn web server and the Gunicorn application server. Uvicorn is a high-performance, pure-Python HTTP server based on the HTTP protocol specification, and Gunicorn is a Python WSGI HTTP Server for UNIX.
Tiangolo Uvicorn-Gunicorn is intended to be used as a production-ready web server for deploying Python web applications, such as those built with the FastAPI web framework. It is designed to be lightweight and efficient, with the goal of being able to handle high loads with minimal overhead.
To use Tiangolo Uvicorn-Gunicorn, you will need to install it in your Python environment and then specify it as the server when you deploy your application. You can then start the server using a command-line interface, and your application will be available at a specified URL.

How to do logging in a FastApi container, any logging does not appear
After much hard work and dedication, success was eventually found! To make it possible to access HTTP request info when running unicorn through gunicorn making just a few minor adjustments is all that’s needed. Append the corresponding snippet to your main.py file; then everything will be ready for use!
import logging from fastapi.logger import logger as fastapi_logger gunicorn_error_logger = logging.getLogger("gunicorn.error") gunicorn_logger = logging.getLogger("gunicorn") uvicorn_access_logger = logging.getLogger("uvicorn.access") uvicorn_access_logger.handlers = gunicorn_error_logger.handlers fastapi_logger.handlers = gunicorn_error_logger.handlers if __name__ != "__main__": fastapi_logger.setLevel(gunicorn_logger.level) else: fastapi_logger.setLevel(logging.DEBUG)
It has been established that our gunicorn.error logger can now handle uvicorn.access information from HTTP requests with no extra effort!
