如何使用 python 3 编辑和保存 azure function 应用程序的配置环境变量？

Question

I am working on a project where I have to edit and save azure function variable using python3 in a set of time period(Azure Timer Trigger). I use this to get the env variable,

import os
departmentid = str(os.getenv("departmentID"))

But it is able to get not to do any edit... and I got this also, https://docs.microsoft.com/en-us/azure/azure-app-configuration/quickstart-python#update-a-configuration-setting

But it is working in Azure App Config not in Azure App Function. Can anyone suggest a solution to edit and save new value to particualr env keys using python3?

Answer 1

Environment Variables are configured for the Function App in Azure Functions from portal and can be accessible by all functions within that app. They are set from the 'Configuration' tab of the left pane's Settings.

Provide a name and a value of your variable to add your own application setting by clicking on New application setting and Then click on 'Save'.

and then try the below code within your function code to access the environment variable.

import os new_db_flag = int(os.environ["NEW_DB_FLAG"])

To edit the same you can navigate to the configurations page -> click on the variable that you wanted to change -> edit the value of it and click save.

NOTE: If your Function app runs on Consumption plan then it allows only one deployment slot .
