az functionapp deployment fails when deploying to an app with identity based connection for storage

[paulbatum]

Describe the bug
Deploying to a function app that uses an identity based connection for AzureWebJobsStorage (e.g. AzureWebJobsStorage__accountName) fails validation when running
az functionapp deployment source config-zip.

To Reproduce
Follow the steps outlined here.

Expected behavior
Deployment should complete.

Actual behavior
Deployment fails with the error Could not find a 'AzureWebJobsStorage' application setting

Environment summary
azure-cli 2.11.0
core 2.11.0
telemetry 1.0.5

Extensions:
appservice-kube 0.1.7

Python location 'C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\python.exe'
Extensions directory 'C:\Users\pbatum.azure\cliextensions'

Python (Windows) 3.6.8 (tags/v3.6.8:3c6b436a57, Dec 23 2018, 23:31:17) [MSC v.1916 32 bit (Intel)]

Additional context

Looks like this validation logic is the problem:

azure-cli/src/azure-cli/azure/cli/command_modules/appservice/custom.py

Lines 539 to 545 in d1676f6

	storage_connection = None
	for keyval in settings:
	if keyval['name'] == 'AzureWebJobsStorage':
	storage_connection = str(keyval['value'])
	if storage_connection is None:
	raise CLIError('Could not find a \'AzureWebJobsStorage\' application setting')

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @ahmedelnably, @fabiocav.

Thanks @paulbatum, it looks like this is going to require some additional changes because we assume it's going to be a connection string here.

When not using Azure Files but using Managed Identity for AzureWebJobsStorage

az functionapp deployment should default to remote build. As the app is not using Azure Files, if using Run from package =1, content will upload to data\sitePackages - Windows Consumption, Dedicated, Linux Dedicated.

When using Azure Files but using Managed Identity for AzureWebJobsStorage

• Remote build does not work without key vault references or full connection string. This is currently blocked on Azure Files supporting mounting vis Managed Identity.

Any idea when it would be fixed ? :)

Any Estimate on the fix ? Seems the main thread is locked and being looked into?
Azure/azure-functions-core-tools#2671

In case anyone stumbles over this issue, I found a workaround. Basically setting the config setting core tools is looking for, then running core tools, then restore the original settings. I made a PS wrapper script for the core tools call to make this work until core tools get fixed. So if anyone needs a quick&dirty solution, here it is: https://github.com/ArunasFalcon/MIAzureFunctionDeployWrapper

Has there been any attention on this?
