amazon-web-services - 在 Terraform 销毁期间，terraform 在销毁 Auto-scaling 组之前尝试销毁 ECS 集群并且失败了

问题描述

我已将 ECS 与容量提供程序一起用于部署我的应用程序，并为容量提供程序使用的 ASG 启用了缩减保护。在 Terraform 销毁期间，我看到 terraform 试图销毁 ECS 集群，尝试 10 分钟后它失败并输出， 错误：删除 ECS 集群时出错：ClusterContainsContainerInstancesException：当容器实例处于活动状态或耗尽时，无法删除集群。

我在这里做错了什么，

相关的 Terraform 脚本，

对于 ECS

#ecs auto-scaling
resource "aws_appautoscaling_target" "ecs_target" {
  max_capacity       = var.ecs_max_size -- (8)
  min_capacity       = var.ecs_min_size -- (2)
  resource_id        = "service/${aws_ecs_cluster.kong.name}/${aws_ecs_service.kong.name}"
  scalable_dimension = "ecs:service:DesiredCount"
  service_namespace  = "ecs"
}

resource "aws_appautoscaling_policy" "ecs_asg_cpu_policy" {
  name               = local.name
  policy_type        = "TargetTrackingScaling"
  resource_id        = aws_appautoscaling_target.ecs_target.resource_id
  scalable_dimension = aws_appautoscaling_target.ecs_target.scalable_dimension
  service_namespace  = aws_appautoscaling_target.ecs_target.service_namespace

  target_tracking_scaling_policy_configuration {
    predefined_metric_specification {
      predefined_metric_type = "ECSServiceAverageCPUUtilization"
    }

    target_value = 70
  }
}

Terraform 版本： Terraform v0.14.7

解决方案

这是GitHub 中报告的一个长期存在的问题：

目前，似乎没有任何解决方案，除了手动干预或使用 AWS CLI 的 local-exec 临时来帮助 TF。
