Python script sub directory path in Azure Functions

Question

I currently have a python project that contains python script, and azure function files. This is the structure of the project:

├── ansible-deploy-pipelines.yml
├── ansibleazurefunc
│   ├── __init__.py
│   ├── function.json
│   └── sample.dat
├── config
│   ├── env
│   │   ├── envvars
│   │   ├── extravars
│   │   ├── passwords
│   │   ├── settings
│   │   └── ssh_key
│   ├── inventory
│   │   └── hosts
│   └── project
│       ├── roles
│       │   └── linux-vms
│       │       ├── README.md
│       │       ├── defaults
│       │       │   └── main.yml
│       │       ├── handlers
│       │       │   └── main.yml
│       │       ├── meta
│       │       │   └── main.yml
│       │       ├── tasks
│       │       │   └── main.yml
│       │       ├── tests
│       │       │   ├── inventory
│       │       │   └── test.yml
│       │       └── vars
│       │           └── main.yml
│       └── test.yml
├── host.json
├── local.settings.json
├── proxies.json
├── requirements.txt
└── scripts
    ├── deploy_config.py
    ├── hosts
    └── playbook.yml

The python script:

#!/usr/bin/env python3

import os
import sys
from collections import namedtuple

from ansible.parsing.dataloader import DataLoader
from ansible.vars.manager import VariableManager
from ansible.inventory.manager import InventoryManager
from ansible.executor.playbook_executor import PlaybookExecutor


loader = DataLoader()

def main()
    inventory = InventoryManager(loader=loader, sources='hosts')
    variable_manager = VariableManager(loader=loader, inventory=inventory)
    playbook_path = 'playbook.yml'

    if not os.path.exists(playbook_path):
        print("[INFO] The playbook does not exist")
        sys.exit()

    Options = namedtuple('Options', ['listtags', 'listtasks', 'listhosts', 'syntax', 'connection','module_path', 'forks', 'remote_user', 'private_key_file', 'ssh_common_args', 'ssh_extra_args', 'sftp_extra_args', 'scp_extra_args', 'become', 'become_method', 'become_user', 'verbosity', 'check','diff'])
    options = Options(listtags=False, listtasks=False, listhosts=False, syntax=False, connection='ssh', module_path=None, forks=100, remote_user='devadmin', private_key_file='../config/env/ssh_key', ssh_common_args=None, ssh_extra_args=None, sftp_extra_args=None, scp_extra_args=None, become=True, become_method='sudo', become_user='root', verbosity=None, check=False, diff=False)


    passwords = {}

    tp = PlaybookExecutor(playbooks=[playbook_path], inventory=inventory, variable_manager=variable_manager, loader=loader, options=options, passwords=passwords)

    results = tp.run()
    

if __name__ == '__main__':
    main()

The Azure function init.py file:

import logging 
import json

import azure.functions as func
from scripts import deploy_config


def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python script for calling Ansible playbook.')

    deploy_config.main()
    
    return func.HttpResponse(f"Ansible deploy - Completed")

The entire project is deployed using azure pipelines, which successfully complete the build and release pipelines. However, the script fails to execute. I have had the script executed standalone to confirm it works.

The confusion for me is how to configure the path to the playbook.yml and hosts files within Azure function. I am unable to debug within azure functions to see any possible errors that might be helpful.

How do I set this path within Azure functions? The following paths obviously work locally:

private_key_file='../config/env/ssh_key'

inventory = InventoryManager(loader=loader, sources='hosts')

playbook_path = 'playbook.yml'

I'm quite new to Azure functions, but I believe setting the path correctly might be the solution to this issue. I am not sure what I'm missing.
