这是我的 Terraform 代码，用于创建 AKS 集群并允许它使用我的 ACR（在同一订阅中）：

resource "azurerm_kubernetes_cluster" "aks" {
  name                      = var.aks-cluster-name
  location                  = azurerm_resource_group.rg.location
  resource_group_name       = azurerm_resource_group.rg.name
  kubernetes_version        = "1.18.8"
  dns_prefix                = "${var.aks-cluster-name}-dns"

  default_node_pool {
    name                  = "default"
    vm_size               = "Standard_D2_v2"
    enable_auto_scaling   = false
    node_count            = 3
    availability_zones    = ["1", "2", "3"]
    type                  = "VirtualMachineScaleSets"
    enable_node_public_ip = false
  }

  network_profile {
    network_plugin = "azure"
    load_balancer_sku = "standard"
  }

  identity {
    type = "SystemAssigned"
  }

  addon_profile {
    oms_agent {
      enabled                    = true
      log_analytics_workspace_id = data.azurerm_log_analytics_workspace.log_workspace.id
    }
    kube_dashboard {
      enabled = false
    }
    azure_policy {
      enabled = false
    }
  }
}

data "azurerm_container_registry" "acr_name" {
  name = "myacr"
  resource_group_name = "acr_rg"
}

resource "azurerm_role_assignment" "aks_to_acr_role" {
  scope                = data.azurerm_container_registry.acr_name.id
  role_definition_name = "AcrPull"
  principal_id         = azurerm_kubernetes_cluster.aks.kubelet_identity[0].object_id
}

我收到此错误（状态 = 403 代码 =“授权失败”）：

azurerm_role_assignment.aks_to_acr_role: Creating...
Error: authorization.RoleAssignmentsClient#Create: Failure responding to request: StatusCode=403 -- Original Error: autorest/azure: Service returned an error.

    on main.tf line 91, in resource "azurerm_role_assignment" "aks_to_acr_role":
    91: resource "azurerm_role_assignment" "aks_to_acr_role" {

我为我的 AKS 使用了托管标识，而不是主体服务。

谢谢你的帮助 ..

问题是运行 terraform 代码的服务主体无权将 AcrPull 角色分配授予 AKS 托管标识。这是一个 AD 权限问题。

要么授予服务主体（执行 terraform 代码的人）一个 Owner 角色（Contributor 还不够），要么授予它一个有权执行Microsoft.Authorization/roleAssignments/write操作的自定义角色。
