async environment and gunicorn

[davidshen84]

Hi,

import asyncio
import uvicorn

async def app(scope, receive, send):
    data = await func()
    app = FastAPI()
    return app

async def main():
    config = uvicorn.Config("main:app", port=5000, log_level="info", workers=4)
    server = uvicorn.Server(config)
    await server.serve()

if __name__ == "__main__":
    asyncio.run(main())

I can start the app with python main.py, but I cannot start it using the "uvicorn" cli app. Also, I want to us the "gunicorn" server. I also noticed, it seems I can only start one worker even though I set workers to 4.

What is the recommended way to use top level async with uvicorn/gunicorn?

Thanks
