Description

I have below code: main.tf

module "naming" { source = "Azure/naming/azurerm" version = ">= 0.4.1" }

resource "azurerm_resource_group" "rg" { location = var.location name = module.naming.resource_group.name_unique }

resource "azurerm_user_assigned_identity" "user_identity" { location = azurerm_resource_group.rg.location name = var.kubernetes_cluster_name resource_group_name = azurerm_resource_group.rg.name }

module "aks" { source = "Azure/avm-ptn-aks-production/azurerm" kubernetes_version = var.kubernetes_version enable_telemetry = var.enable_telemetry name = module.naming.kubernetes_cluster.name_unique resource_group_name = azurerm_resource_group.rg.name managed_identities = { user_assigned_resource_ids = [ azurerm_user_assigned_identity.user_identity.id ] }

location = azurerm_resource_group.rg.location node_pools = { workload = { name = var.system_node_pool_name vm_size = var.vm_size orchestrator_version = var.kubernetes_version max_count = 10 min_count = 1 os_sku = var.os_sku mode = var.mode } } }

Provider.tf

terraform { required_version = ">= 1.3.0" required_providers { azurerm = { source = "hashicorp/azurerm" version = ">= 3.7.0, < 4.0.0" } } }

provider "azurerm" { features { resource_group { prevent_deletion_if_contains_resources = false } } }

Variable.tf

hello @nrv-96 . The problem is the nodepool name that is too long

│ Error: the "name" must begin with a lowercase letter, contain only lowercase letters and numbers and be between 1 and 12 characters in length, got "npnpsystmnodp3"

@zioproto , Can you please add custom option enable and disable for log analytics and ACR registry?

Sorry, this is a "pattern" module that includes ACR and Log Analytics. If you need more flexibility you should use https://github.com/Azure/terraform-azurerm-aks
