azure-aks-private-cluster¶
Ensure that AKS enables private clusters which will further restrict access to the Kubernetes API to the internal network only.
Ensuring that your Kubernetes API server is only accessible to the private network enables you to further reduce your attack surface against accidental misconfigurations or unpatched exploits.
Examples¶
Insecure Example
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_D2_v2"
}
identity {
type = "SystemAssigned"
}
