Description

Encryption in transit for azure storage is now in preview for AKS (https://docs.microsoft.com/en-us/azure/aks/enable-host-encryption#use-host-based-encryption-on-new-clusters-preview). Please add the needed flag as an option for AKS node pools.

This feature is available many vm sku's, but not all. It may be worth delegating to the azure api when trying to set the flag. It also seems like changing the flag requires the node pool to be recreated.

New or Affected Resource(s)

• azurerm_kubernetes_cluster (default_node_pool specifically)
• azurerm_kubernetes_cluster_node_pool

Potential Terraform Configuration

resource "azurerm_kubernetes_cluster" "example" {
  name                = "example-aks1"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  dns_prefix          = "exampleaks1"

  default_node_pool {
    name       = "default"
    node_count = 1
    vm_size    = "Standard_D2s_v2"
    enable_encryption_at_host = true //Set to true to activate the preview functionality. 
  }
}

resource "azurerm_kubernetes_cluster_node_pool" "example" {
  name                  = "internal"
  kubernetes_cluster_id = azurerm_kubernetes_cluster.example.id
  vm_size               = "Standard_DS2_v2"
  node_count            = 1
  enable_encryption_at_host = true //Set to true to activate the preview functionality.

I'll take a look into this, seems like it may be available in the current Go SDK
