amazon-web-services - 地形 | AWS ECS 服务 |每个 tf apply 所需的计数值更改

Question

当我做 terraform apply每次所需的计数从 1 -> 2 变化时。请提出建议。
但是在 variables.tf , 我声明为 desired_count=2 .

~ resource "aws_ecs_service" "ecs_service" {
         cluster                            = "arn:aws:ecs::cluster/"
         deployment_maximum_percent         = 200
         deployment_minimum_healthy_percent = 100
       ~ desired_count                      = 1 -> 2
         enable_ecs_managed_tags            = false
         force_new_deployment               = true
         health_check_grace_period_seconds  = 0
         iam_role                           = "aws-service-role"
         id                                 = "arn:aws:ecs:-ecs-service"
         launch_type                        = "FARGATE"
         name                               = "ecs-service"
         platform_version                   = "LATEST"
         propagate_tags                     = "NONE"
         scheduling_strategy                = "REPLICA"
         tags                               = {}
         task_definition                    = "arn:aws:ecs:"
         deployment_controller {
             type = "ECS"
         }
         load_balancer {
             container_name   = "abcd"
             container_port   = 80
             target_group_arn = "arn.*"
         }
         network_configuration {
             assign_public_ip = false
             security_groups  = []
             subnets          = []
         }
     }

这是main.tf:-
备注 :- 我正在使用模块来调用 main.tf。

############ ECS Service ##############
resource "aws_ecs_service" "ecs_service" {
  name                 = "${var.name}-ecs-service"
  cluster              = var.cluster_id
  task_definition      = var.task_definition_arn
  desired_count        = var.desired_count
  iam_role             = var.ecs_iam_role
  force_new_deployment = var.force_new_deployment
  launch_type          = "FARGATE"
  deployment_controller {
    type = "ECS"
  }
  deployment_maximum_percent         = "200"
  deployment_minimum_healthy_percent = "100"
  load_balancer {
    target_group_arn = var.lb_tg_arn
    container_name   = var.name
    container_port   = var.port
  }
  network_configuration {
    security_groups  = var.security_group_id
    subnets          = var.subnets
    assign_public_ip = var.assign_public_ip
  }
  depends_on = [var.aws_alb]
}

通过设置 default=null 来根据我的项目的要求分配变量

不确定是什么真正导致了更改，但如果您只想静音更改，您可以忽略 terraform docs 中所述的更改。

resource "aws_ecs_service" "example" {
  # ... other configurations ...

  # Example: Create service with 2 instances to start
  desired_count = 2

  # Optional: Allow external changes without Terraform plan difference
  lifecycle {
    ignore_changes = [desired_count]
  }
}
