通过Azure中的Terraform为VM实例创建托管系统标识

Question

尝试使用Terraform为VM创建受管系统身份。使用Status = 404 Code =“ MissingSubscription”

错误提示

尝试为VM创建受管系统身份。这是代码段：

###############################################################################
# Create Managed System Identity for VMs
###############################################################################

data "azurerm_subscription" "primary" {}

 data "azurerm_builtin_role_definition" "contributor" {
   name = "Contributor"
 }

resource "azurerm_role_assignment" "contributor" {
  name                = "[${element(azurerm_virtual_machine.consul.*.id, count.index + 1)}]"
  scope              = "${var.subscription_id}"
 #scope              = "${data.azurerm_subscription.primary.id}"
  principal_id       = "${var.tenant_object_id}"
  role_definition_id = "${var.subscription_id}${data.azurerm_builtin_role_definition.contributor.id}"
  }

运行terraform apply会产生以下错误：

错误：

Error: Error applying plan:

1 error(s) occurred:

* azurerm_role_assignment.contributor: 1 error(s) occurred:

* azurerm_role_assignment.contributor: authorization.RoleAssignmentsClient#Create: Failure responding to request: StatusCode=404 -- Original Error: autorest/azure: Service returned an error. Status=404 Code="MissingSubscription" Message="The request did not have a subscription or a valid tenant level resource provider."

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.

我尝试遵循此处描述的示例-https://www.terraform.io/docs/providers/azurerm/r/role_assignment.html，但看起来如果我将范围更改回scope = "${data.azurerm_subscription.primary.id}"，则会出现以下错误：

* azurerm_role_assignment.contributor: 1 error(s) occurred:

* azurerm_role_assignment.contributor: authorization.RoleAssignmentsClient#Create: Failure responding to request: StatusCode=405 -- Original Error: autorest/azure: Service returned an error. Status=405 Code="" Message="The requested resource does not support http method 'PUT'."

Answer 1

这里有多个问题：

1. 资源name的{​​{1}}字段必须是GUID，在您的代码中必须有方括号。
2. role_definition_id必须具有单个表达式求值，例如仅azurerm_role_assignment

创建此示例的正确方法是：

${data.azurerm_builtin_role_definition.contributor.id}

假定############################################################################### # Create Managed System Identity for VMs ############################################################################### data "azurerm_subscription" "primary" {} data "azurerm_builtin_role_definition" "contributor" { name = "Contributor" } resource "azurerm_role_assignment" "contributor" { name = "00000000-0000-0000-0000-000000000000" scope = "${data.azurerm_subscription.primary.id}" principal_id = "${var.tenant_object_id}" role_definition_id = "${data.azurerm_builtin_role_definition.contributor.id}" } 变量确实是您的主要订阅中现有的服务主体ID。
