Description

Hi together! I am happy, that since some weeks it's possible to use infrastructure_resource_group_name on azurerm_container_app_environment. Implemented in https://github.com/hashicorp/terraform-provider-azurerm/pull/24361.

The problem is that it's necessary to set workload_profile {} and workload profiles only allows values of "["D4" "D8" "D16" "D32" "E4" "E8" "E16" "E32"]".

I want to use the consumption workload_profile and also set the change the value for infrastructure_resource_group_name. It should not be necessary to specify workload_profile to set the resource group name of the infrastructure, in my opinion.

If I want to deploy without workload_profiles {} I get the following error: │ "infrastructure_resource_group_name": all of `infrastructure_resource_group_name,workload_profile` must be specified.

}

Hi @mschwrdtnr 👋!

I've implemented it, and during my testing I noticed that it was only picked up in combination with a workload_profile.

If you have an example of it working with a consumption workload profile using az cli or portal, please let me know.

Hi @aristosvo ! Thanks for your reply.

Sorry, I don't understand what example you want me to provide with az. I want to use the following terraform code to rename the infrastructure resource group. It should not be necessary to set workload_profile to use infrastructure_resource_group_name. Like I wrote: I am getting an error if I not specify workload_profile but I dont want to because I use consumption only.

resource "azurerm_container_app_environment" "cae_test" {
  name                           = "cae-name"
  location                       = var.location
  resource_group_name            = "rg-cae-test"
  infrastructure_subnet_id       = <subnet-id>
  internal_load_balancer_enabled = true
  infrastructure_resource_group_name = "rg-cae-test-aks"
}

Hi @mschwrdtnr !

I think this is simply not possible and available as functionality in the Azure REST APIs.

The easiest to invalidate that is that you have proof that it is possible via other (azapi or non-terraform) ways to do the things you want. In that case I'll simply backtrack their interaction with the Azure REST APIs and implement it in azurerm.

[mschwrdtnr]

@aristosvo Ahh got it! Thanks for the clarification. I'll try to test it.

I was able to provision container apps environment specifying infrastructure resource group name and without workload profile via az cli:

az extension add --name containerapp
az containerapp env create -n web-platform -g web-platform --location northeurope --infrastructure-resource-group managed-container-app --infrastructure-subnet-resource-id "/subscriptions/<edited>/resourceGroups/infrastructure/providers/Microsoft.Network/virtualNetworks/dev/subnets/container_app_env"

terraform code:

resource "azurerm_container_app_environment" "web_platform" {
  name                               = "web-platform"
  location                           = azurerm_resource_group.web_platform.location
  resource_group_name                = azurerm_resource_group.web_platform.name
  infrastructure_subnet_id           = azurerm_subnet.subnets["container_app_env"].id
  infrastructure_resource_group_name = "managed-container-app"
  tags                               = local.tags
}

result:

│ Error: Unsupported argument
│ 
│   on container_app.tf line 46, in resource "azurerm_container_app_environment" "web_platform":
│   46:   infrastructure_resource_group_name = "managed-container-app"
│ 
│ An argument named "infrastructure_resource_group_name" is not expected here.
