如何通过Terraform在一个Fargate配置文件中指定多个名称空间？

resource "aws_ecs_task_definition" "example" {
  family                   = "my-task"
  execution_role_arn       = aws_iam_role.example.arn
  network_mode             = "awsvpc"
  requires_compatibilities = ["FARGATE"]
  cpu                      = "256"
  memory                   = "512"
}

resource "aws_ecs_task_definition" "example" {
  # ...

  container_definitions = <<DEFINITION
  [
    {
      "name": "container-1",
      "image": "nginx:latest",
      "memoryReservation": 128,
      "namespace": "namespace-1"
    },
    {
      "name": "container-2",
      "image": "mysql:latest",
      "memoryReservation": 256,
      "namespace": "namespace-2"
    }
  ]
  DEFINITION
}
