Question

I cannot recreate a previously deleted Azure Functions and storage account resource on another subscription

Hello,

i'm encountering an issue redeploying several Azure Functions and Storage Account resources, which have been previously created on another subscription, but have been deleted via the Azure Portal prior to recreating (and we waited for a couple of days now between retries).

We are using Terraform v1.10.5 and azurerm v4.22.0 for deployment.

This is the Terraform output (I obfuscated the real resource names):

Storage Account:

Error: creating Storage Account (Subscription: "xyz")

Resource Group Name: "rg-*"

Storage Account Name: "st*": performing Create: unexpected status 409 (409 Conflict) with error: StorageAccountAlreadyTaken: The storage account named st* is already taken.

Function App:

Error: the Site Name "func-" failed the availability check: Hostname 'func-' already exists. Please select a different name.

The Function Apps are Consumption ones, and i verified that the sites cannot be reached via the default URI (*.azurewebsites.net).

I can add the actual resource names in a private conversation.

Thanks,

Torben

The errors you are encountering while trying to recreate the Azure Functions and Storage Account resources are likely due to the global uniqueness requirement for storage account names and function app hostnames in Azure.

Storage Account: The error message "StorageAccountAlreadyTaken" indicates that the storage account name you are trying to use is already in use across Azure. Storage account names must be globally unique, meaning that even if the account was deleted, the name cannot be reused for a certain period. If the name is still in use by another subscription or tenant, you will need to choose a different name.

Function App: The error message regarding the Site Name indicates that the hostname you are trying to use for your function app already exists. Similar to storage accounts, function app hostnames must also be unique across Azure. Even if the function app was deleted, the hostname may still be reserved for a period of time.

To resolve these issues:

Consider using different names for both the storage account and the function app.

Hello Khadeer,

thanks for your input. I'm aware that the global uniqueness of the names must be fulfilled. However, we have done this exercise several times before with a delta of a couple of minutes, and it worked well.

We are also using a corporate naming schema, therefore we cannot simply change the names of the resources.

Is it possible to have an in-depth look into the actual resources, i can provide technical details on the affected instances.

Thanks,
