Azurerm_private_endpoint for redis cache standard sku

Terraform Providers
1

Dear community,

i’m deploying redis cache as “Standard” SKU and public network traffic disabled:

resource "azurerm_redis_cache" "example" {
  name                = "example-${var.env_name}"
  location            = data.azurerm_resource_group.example_rg.location
  resource_group_name = data.azurerm_resource_group.example_rg.name
  capacity            = 1
  family              = "C"
  sku_name            = "Standard"
  enable_non_ssl_port = false
  minimum_tls_version = "1.2"
  redis_version       = 6
  public_network_access_enabled = false

  redis_configuration {
  }
}

The application is running in an PaaS Kubernetes environment which is managed by local IT. For connectivity, I wanted to create a private endpoint via Terraform. I’m facing problems, when it comes to the specification of the subnet_id parameter as redis cache SKU “Standard” is deployed directly into the resource group - for subnetting, we would need to increase the SKU to “Premium”. subnet_id is a required parameter so I can’t skip it and configuring the private-endpoint as follows doesn’t do the trick:

resource "azurerm_private_endpoint" "example_privateEndpoint" {
  name                = "example-private-endpoint-${var.env_name}"
  location            = data.azurerm_resource_group.example_rg.location
  resource_group_name = data.azurerm_resource_group.example_rg.name
  subnet_id           = azurerm_redis_cache.example.subnet_id

[ -- deleted the rest of the code for private dns group etc. -- ]

}

I get the following error:

Error: Missing required argument
│
│ with azurerm_private_endpoint.example_privateEndpoint,
│ on main.tf line 66, in resource “azurerm_private_endpoint” “example_privateEndpoint”:

Did anyone of you guys encounter the same problem and solved it somehow?
