A quick guide to publish Python SDK Azure Bots in App Service

[Shekhar]

This article assumes that you already have created and published Python Bot using the link below:

Provision and publish a bot in Azure - Bot Service | Microsoft Learn

But you might end up facing some issues like below:

• Container pythonbot_### didn't respond to HTTP pings on port: 8000, failing site start
• Container pythonbot_### for site pythonbot has exited, failing site start
• Failed to find attribute 'app' in 'app'.

Probable causes:

App Service configured as Messaging Endpoint could have been missing one or more of the following configurations:

1. App Service --> Configuration --> Application Settings:
   1. MicrosoftAppId (Application Id of the App Registration)
   2. MicrosoftAppPassword (Secret of the App Registration if not ManagedIdentity type)
   3. SCM_DO_BUILD_DURING_DEPLOYMENT: true (build during deployment to true)
      
      
2. App Service --> Configuration --> General Settings: You need to provide a startup command that will be run as part of container startup, you can use the following : 

   gunicorn --bind 0.0.0.0 --worker-class aiohttp.worker.GunicornWebWorker --timeout 600 app:<APP​>

   
   Note : <APP> should be application's root file. By default it is APP is root file name.

I hope this helps.
