Azure Functions: How to run Linux Consumption Zip Deploy?

I am running Linux on WSL and want to publish the hello-world example to an Azure Function using the Linux consumption plan on Python 3.10.

This is not a solution for me: https://stackoverflow.com/questions/71070103/zip-deploy-azure-function-from-storage-account

My hello world example is:

import azure.functions as func
import logging

app = func.FunctionApp(auth_level=func.AuthLevel.ANONYMOUS)

@app.function_name(name="HttpTrigger1")
@app.route(route="hello")
def test_function(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = req.params.get('name')
    if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
    else:
        name = req_body.get('name')

    if name:
        return func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully.")
    else:
        return func.HttpResponse(
            "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
            status_code=200
    )

My local.settings.json is:

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "python",
    "SCM_DO_BUILD_DURING_DEPLOYMENT": true,
    "AzureWebJobsStorage": "redacted",
    "AzureWebJobsFeatureFlags": "EnableWorkerIndexing",
    "WEBSITE_CONTENTSHARE": "redacted",
    "WEBSITE_CONTENTAZUREFILECONNECTIONSTRING": "redacted",
    
  }
}

requirements.txt:

azure-functions

I am deploying by zipping my folder and then using the az cli:

az functionapp deployment source config-zip -g rg_here -n fun_name_here --src my_zip_file.zip

In fact the above nor from the terminal will work, either.

func azure functionapp publish my_fun_name

By not work, I mean that I get either this response:

No HTTP triggers found.

or

Your app is currently in read only mode because you are running from a package file. To make any changes update the content in your zip file and WEBSITE_RUN_FROM_PACKAGE app setting.

And my functions are not visible on the portal or VS Code.

I have followed the commands from the SO 71617500 and it worked for me.

As per MS document1, to enable your function app to run from a package, add a WEBSITE_RUN_FROM_PACKAGE=<URL> setting to your app settings for functions apps running on Linux in a Consumption plan.

Firstly I set the value as "SCM_DO_BUILD_DURING_DEPLOYMENT": true in function app configuration and WEBSITE_RUN_FROM_PACKAGE was automatically added during function app creation.

init.py

import  logging
import  azure.functions  as  func
def  main(req: func.HttpRequest) -> func.HttpResponse:
logging.info('Python HTTP trigger function processed a request.')
name  =  req.params.get('name')
if  not  name:
try:
req_body  =  req.get_json()
except  ValueError:
pass
else:
name  =  req_body.get('name')
if  name:
return  func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully.")
else:
return  func.HttpResponse(
"This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
status_code=200
)

local.settings.json

{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "",
"FUNCTIONS_WORKER_RUNTIME": "python"
}
}

I have only zipped the following function files

Used the below command to deploy the zip file from local cli

az functionapp deployment source config-zip -g iafrin-RG -n afreenfuncapp0123 --src "C:\Users\iafrin\Documents\functionApp\demo-file\hello-world-test-file.zip"

It got deployed successfully

I was able to see the function in the portal along with the warning and in vs code I was able to files in read-only mode as well.

Your app is currently in read only mode because you are running from a package file. To make any changes update the content in your zip file and WEBSITE_RUN_FROM_PACKAGE app setting.

Above warning says, I can't edit my files from the portal as It is running from a package and according to MS document2, portal editing is enabled only for HTTP and Timer triggers for Functions on Linux using Premium and Dedicated plans not for Consumption plan.
