Terraform无效的depends_on引用

Question

升级到0.13版本后，Terraform出现以下错误

错误:输出“config”中模块/iam/outputs.tf第10行的depends_on引用无效: 7: aws_iam_role_policy_attachment.eks_worker_node.policy_arn，

depends_on中的引用必须是对整个对象(资源等)的引用，而不是对对象的属性的引用。此错误在从7到11的所有行上持续存在。以下是IAM模块的输出文件：

output "config" {
      value = {
        service_role = aws_iam_role.eks_service_role.name
        node_role    = aws_iam_role.eks_node.name
      }
      depends_on = [
        aws_iam_role_policy_attachment.eks_worker_node.policy_arn,
        aws_iam_role_policy_attachment.eks_cni.policy_arn,
        aws_iam_role_policy_attachment.ecr.policy_arn,
        aws_iam_role_policy_attachment.eks_service_policy.policy_arn,
        aws_iam_role_policy_attachment.eks_cluster_policy.policy_arn,
      ]
    }

Answer 1

根据错误消息，depends_on参数值应该引用对象，而不是导出的属性。您可以更新为：

depends_on = [
  aws_iam_role_policy_attachment.eks_worker_node
  aws_iam_role_policy_attachment.eks_cni,
  aws_iam_role_policy_attachment.ecr,
  aws_iam_role_policy_attachment.eks_service_policy,
  aws_iam_role_policy_attachment.eks_cluster_policy
]

以符合新的用法。
