Deployment issue with Azure App Service with Terraform: 'Dynamic SKU, Linux Worker' not available in resource group

Anita A 110

Hello,
while trying to deploy App Service Plan thought terraform I get this error:
Code="BadRequest" Message="Requested features 'Dynamic SKU, Linux Worker' not available in resource group. Please try using a different resource group or create a new one." I am trying to deploy a Consumption Service Plan (Linux, Y1), and in the resource group I already have (Windows, S1) and (Linux, P0v3) service plans. The issue happens on prod environment, on dev environment it works ( with a slight difference, the (Linux, P0v3) service plan was added last). What could be the reason for this? Are there any limitations for resource groups?
Thanks!

@Anita A , thanks for posting this question. Just to clarify, in which region are you provisioning the resources (on prod)? Is both prod and dev environment on the same subscription or they different? Typically, you should be able to create Windows and Linux app service plans in same resource group. Reference thread

Hi @ajkuma, I deploy them to different subscriptions, development and prod. The region is West Europe. And the resource group was created couple months ago.

Just noticed that the error has this error code
{"ErrorEntity":{"Code":"BadRequest","ExtendedCode":"59324","Message":"Requested features 'Dynamic SKU, Linux Worker' not available in resource group**
**
which lead me to https://learn.microsoft.com/en-us/azure/azure-functions/functions-scale#limitations-for-creating-new-function-apps-in-an-existing-resource-group
"You create a function app in an existing resource group that has ever contained another function app or web app. For example, Linux Consumption apps are not supported in the same resource group as Linux Dedicated or Linux Premium plans."
^^Does this apply?
But even it does, how was I able to create the function in dev environment, with the change that first the Consumption plan was created and then the Premium one?

@Anita A , thanks for the follow-up.

Your understanding is correct, so it could be due to the condition, the webspace, stamp association with support for feature when it was initially created.

The reason this happens is due to how function app and web app plans are mapped to different pools of resources when being created. Different SKUs require a different set of infrastructure capabilities.

Apologies for any inconvenience with this limitation. Much appreciate your feedback. I'll relay this feedback internally.

I'll summarize and post an answer, please Accept my answer for other community members to find the answers quickly.

Answer 1

@Anita A , Thanks for follow-up and your update.

Scenario:

Create a app in an existing Resource Group (RG) that has ever contained another function app or web app, with both Windows and Linux workers on RG, and consumption Service Plan.

Issue:

Error encountered {"ErrorEntity":{"Code":"BadRequest","ExtendedCode":"59324","Message":"Requested features 'Dynamic SKU, Linux Worker' not available in resource group**

Possible causes:

The reason this happens is due to how function app and web app plans are mapped to different pools of resources when being created. Different SKUs require a different set of infrastructure capabilities.

Limitations for creating new function apps in an existing resource group

This can happen when the following conditions are met:

You create a function app in an existing resource group that has ever contained another function app or web app. For example, Linux Consumption apps are not supported in the same resource group as Linux Dedicated or Linux Premium plans.
Your new function app is created in the same region as the previous app.
The previous app is in some way incompatible with your new app. This can happen between SKUs, operating systems, or due to other platform-level features, such as availability zone support.

Solution:

Create your function app and hosting plan in a new RG.
