在 Terraform v13 中创建自动缩放策略和 cloudwatch 警报资源时，它们创建得很好。然而，在对端点进行负载测试时，他们成功地扩展了实例，但当 CPU 利用率在一段时间内达到必要的百分比时，他们无法缩小实例。错误看起来像这样：

"historySummary": "无法执行 AutoScaling 操作：未找到指标值 [5.99763732496649、2.7634547331059975] 和违规增量 -4.00236267503351 的步长调整"

下面列出了地形资源：

自动缩放策略 -

resource "aws_appautoscaling_policy" "frontend_down" {
  name               = "${var.name}_frontend_scale_down"
  service_namespace  = "ecs"
  resource_id        = "service/${aws_ecs_cluster.main.name}/${aws_ecs_service.frontend.name}"
  scalable_dimension = "ecs:service:DesiredCount"

  step_scaling_policy_configuration {
    adjustment_type         = "ChangeInCapacity"
    cooldown                = 30
    metric_aggregation_type = "Maximum"

    step_adjustment {
      metric_interval_lower_bound = 0
      scaling_adjustment          = -1
    }
  }

  depends_on = [aws_appautoscaling_target.frontend_target]
}

云表警报 -

resource "aws_cloudwatch_metric_alarm" "frontend_service_cpu_low" {
  alarm_name          = "${var.name}_cpu_utilization_low_fe"
  comparison_operator = "LessThanOrEqualToThreshold"
  evaluation_periods  = "2"
  metric_name         = "CPUUtilization"
  namespace           = …

我不确定使用 React 测试库的 Render 的自定义渲染函数的返回类型，我假设它是 element 或 JSX，但这似乎不起作用。

代码：

import React, { ReactElement } from 'react'
import { render, RenderOptions } from '@testing-library/react'
import { theme } from './theme'
import { ThemeProvider } from 'styled-components'
import { Provider } from 'react-redux'
import { createStore } from 'redux'
import { searchReducer, initialState } from './store/reducer/searchReducer'

const store = createStore(searchReducer, initialState)

interface ProviderProps { 
  children?: NonNullable<React.ReactNode>
}

const TheProvider: React.FC<ProviderProps> = ({
  children,
}) => {
  return (
    <Provider store={store}>
      <ThemeProvider theme={theme}> …
