I am trying to run fastapi in docker but i am getting error. I am using docker run -d -p 8080:8080 onetest to run the container. I was unable to rectify this error. When i run the application without docker locally i am not facing any problem. I am having this problem with running fastapi with docker.

gunicorn_config.py

bind = "0.0.0.0:8080"
workers = 4
timeout = 300
worker_class = "uvicorn.workers.UvicornWorker"
