@tombuildsstuff, I don't understand your answer at 11430. Is there any solution? Thanks!

@dhabierre to disable the public_network_access_enabled or set private_static_ip_address you need specific a azurerm_virtual_network and subnet for the redis cache

resource "azurerm_resource_group" "example" {
	name     = "test"
	location = "eastus"
  }
  
  resource "azurerm_virtual_network" "example" {
	name                = "test"
	address_space       = ["10.0.0.0/16"]
	location            = azurerm_resource_group.example.location
	resource_group_name = azurerm_resource_group.example.name
  }
  
  resource "azurerm_subnet" "example" {
	name                 = "test"
	resource_group_name  = azurerm_resource_group.example.name
	virtual_network_name = azurerm_virtual_network.example.name
	address_prefixes     = ["10.0.2.0/24"]
  }
  
  
  resource "azurerm_redis_cache" "redis_cache" {
	name                          = "test"
	location                      = azurerm_resource_group.example.location
	resource_group_name           = azurerm_resource_group.example.name
	capacity                      = 1
	family                        = "P"
	sku_name                      = "Premium"
	public_network_access_enabled = false
	private_static_ip_address     = "10.0.2.19"
	enable_non_ssl_port           = false
	minimum_tls_version           = "1.2"
  
	subnet_id = azurerm_subnet.example.id
  }

Hi @xuzhang3 and thanks for your reply.

Ok, subnet_id value is required when using private_static_ip_address, right!

azurerm_redis_cache documentation says:

subnet_id - (Optional) Only available when using the Premium SKU The ID of the Subnet within which the Redis Cache should be deployed. This Subnet must only contain Azure Cache for Redis instances without any other type of resources.

Strange thing by the way: This Subnet must only contain Azure Cache for Redis instances without any other type of resources.

In my subnet there are VMs.
So according to this, I could'nt use Basic sku with static private IP?
Right?

Thanks.

@dhabierre yes, according to this doc you need upgrade the SKU to Premium if you need private_static_ip_address andsubnet_id. Also subnet can only contains Redis caches. I tried with create a VM with the same subnet, the resource can be created but I think there's some issues with the network/connection not tried that.

Hi @xuzhang3,
