使用Terraform创建Fargate任务定义时如何指定操作系统家族？

你需要在aws_ecs_task_definition资源中新增runtime_platform配置块，AWS的operatingSystemFamily属性对应这个块下的operating_system_family参数，修改后的配置如下：

resource "aws_ecs_task_definition" "transform_service" {
  family                   = "${var.app_name}-transform-service-task"
  network_mode             = "awsvpc"
  requires_compatibilities = ["FARGATE"]
  cpu                      = 2 * 1024  #2 vCPU
  memory                   = 16 * 1024 # 16GB
  execution_role_arn       = aws_iam_role.transform_service_task_execution_role.arn

  # 新增运行时平台配置
  runtime_platform {
    operating_system_family = "WINDOWS_SERVER_2019_CORE"
    cpu_architecture        = "X86_64"
  }
  
  container_definitions = jsonencode([{
    name      = "transform-service-container-${var.environment}"
    image     = "${var.transform_service_repository_url}:latest"
    essential = true
    environment = [{
      "name" : "DOTNET_ENVIRONMENT", "value" : "Development"
    }]
  }])
}

注意事项 #

• 需要使用v3.74.0及以上版本的HashiCorp AWS Provider，更低版本不支持runtime_platform配置
• 操作系统家族的取值为AWS规定的枚举值，不能直接使用Windows Server 2019 Core字符串
• Fargate Windows容器仅支持X86_64架构，不需要修改CPU架构参数
