Please do not add this FUNCTIONS_EXTENSION_VERSION app setting for Flex Consumption function apps. It will eventually be blocked for Flex Consumption apps and is not required. The runtime version that this conveyed for other hosting plans is now handled automatically by the platform for Flex Consumption.

This list might not be true for all regions, and we might introduce new instance sizes in the future. The actual list per region comes from the Stacks API but that is dynamic, not sure if we can use it in terraform to validate right? So here we have to decide:

  • Do we not validate and let the user put any number (which if they put incorrectly will show a control plane exception)
  • Or do we put the current list here of all possible current instance sizes here, and then keep updating the list of values as new instance sizes are introduced?

From our perspective, we would rather have new sizes available immediately and a control plane exception kick up, rather than having to wait for the AzureRM team to fix it each time a new size is available. My vote is for option 1 (no validation).

removed the restriction.

@angel-gutierrez-accumulus

Hello,

any ETA for this to be released? We just got a meeting with one of your Azure ACE and he recommended to use Flex Consumption plans.

We can create the resources manually but we are using terraform.
