Azure Function Apps | App Settings Update

Abhay Chandramouli 1,061

Hi

I have an Azure Function App, which has auto scaling enabled.
I have updated an app setting via TF. But intermittently I am still seeing the Function App using the older value.

Can you let me know what can be the issue ? And how much time does it take to update the app settings ?

@Abhay Chandramouli Thanks for reaching out. There might be a delay in propagating the new settings to all instances of your Function App, especially if auto-scaling is enabled and there are multiple instances running. Sometimes, a manual restart of the Function App is required for the new settings to take effect.

As for the time it takes to update the app settings, it usually happens immediately but can take a few minutes in some cases. However, as mentioned above, you might need to manually restart your Function App to ensure the new settings are picked up

do let me know incase of further queries, I would be happy to assist you.
