Not able to publish azure python function app with external dependencies (not in index)

Question

I have an simple python module AdditionalLibrary, I do not want to publish it nowhere public. I have also an azure python serverless function app ExamplePythonServerlessFunction I want to publish on azure.

I followed official documentation:

• https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-first-function-python
• https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference-python

and an out-dated page https://prmadi.com/install-python-modules-on-azure-app-services/

Finally I have a wheelhouse directory in my azure function project containing *.whl files for every dependency I need. I try to put additional flags to my requirments.txt file to use wheelhouse directory instead of index. This is content of my requirments.txt file.

--no-index --find-links file://wheelhouse
Additional-Library==1.0
azure-functions==1.0.0b4
azure-functions-worker==1.0.0b6
grpcio==1.20.1
grpcio-tools==1.20.1
protobuf==3.6.1
six==1.11.0

During publishing the app:

$ func azure functionapp publish ${APP_NAME} --build-native-deps

I get an error:

  Url 'file://wheelhouse' is ignored: it is neither a file nor a directory.

and I am not able to install dependencies. Is that way is correct? How can I install some additional dependencies to azure function app.

Any help and advice will be appreciated.

I've been doing this:

import os
import sys
sys.path.append(os.path.abspath(os.path.join(os.path.dirname( __file__ ), '../../../az/Lib/site-packages')))
from azure.storage.cloudstorageaccount import CloudStorageAccount,AccountPermissions,Services,ResourceTypes
from azure.storage.blob import BlockBlobService

so you can just create a directory in your function and add it to path and import modules from that path.
