Facing Container startup issue, when deploying Quart App in Azure APP service

I'm trying to deploy a Quart application to Azure App Service using a Docker container, but I'm running into an issue where the Docker container fails to start on port 8000 and disconnects.

from quart import Quart

app = Quart(__name__)

@app.route('/')
async def hello():
    return 'Hello, World!'

if __name__ == '__main__':
    app.run()

Startup command Used : hypercorn -b 0.0.0.0:8080 app:app

Other configurations

SCM_DO_BUILD_DURING_DEPLOYMENT=1

Deployment Type : Manual Deployment from VS Code

App service Plan : Basic - Linux

Error Faced: ERROR - Container for site has exited, failing site start ERROR - Container didn't respond to HTTP pings on port: 8080, failing site start. See container logs for debugging.

Expected Outcome:

Container needs to be started and need to also verify the startup command given was correct w.r.t to Quart

Based on the error message provided, the issue is related to the startup command.

I tried configuring the startup command that you've used, but I got the same error. So, I changed the startup command to

gunicorn -w 4 -k uvicorn.workers.UvicornWorker app:app

I created a simple Quart application and successfully deployed it to Azure App Service without any issues.

This is requirements.txt:

quart
hypercon
gunicorn
uvicorn

app .py:

import  os
from  quart  import  Quart
app  =  Quart(__name__ 
@app.route('/')
async  def  hello():
return  'Hello, World!'
if  __name__  ==  '__main__':
port  =  int(os.environ.get("PORT", 8080))
app.run(host='0.0.0.0', port=port)

I deployed the app successfully via visual studio code extension.

configure the below startup command to azure app service.

Here's the output after deployment:
