小编sam*_*ler的帖子

我正在尝试从 Node.js lambda 函数调用步骤函数。我尝试了该线程的解决方案并更新了实现。

显示错误响应的解决方案，但更新后的代码显示成功响应。但更新后的代码没有调用step函数。

我的代码：

console.log('Loading function');
const AWS = require('aws-sdk');
exports.handler = function(event, context) {
    console.log('Loading step functions');
    const stepFunctions = new AWS.StepFunctions({
    region: 'us-east-2'
});
console.log('Loading init');
module.exports.init = (event, context, callback) => {
console.log('Loading params');
const params = {
        stateMachineArn: 'ARN of My State Machine',
        // input: JSON.stringify({}), Optional if your statemachine requires an application/json input, make sure its stringified 
        name: 'TestExecution' // name can be anything you want, but it should change for …

这是一个示例cloudwatch_metric_alarm resource：

    resource "aws_cloudwatch_metric_alarm" "nlb_healthyhosts" {
  alarm_name          = "alarmname"
  comparison_operator = "LessThanThreshold"
  evaluation_periods  = "1"
  metric_name         = "HealthyHostCount"
  namespace           = "AWS/NetworkELB"
  period              = "60"
  statistic           = "Average"
  threshold           = var.logstash_servers_count
  alarm_description   = "Number of healthy nodes in Target Group"
  actions_enabled     = "true"
  alarm_actions       = [aws_sns_topic.sns.arn]
  ok_actions          = [aws_sns_topic.sns.arn]
  dimensions = {
    TargetGroup  = aws_lb_target_group.lb-tg.arn_suffix
    LoadBalancer = aws_lb.lb.arn_suffix
  }
}

我仍然不明白警报操作参数。在 terraform 文档中，我们有：

Alarm_actions -（可选）当该警报从任何其他状态转换为 ALARM 状态时要执行的操作列表。每个操作都指定为 Amazon 资源名称 (ARN)。

有人可以给我一个具体的例子吗，例如发送电子邮件/和/创建 SNS 主题（没有现有主题 ARN ）。

我预先非常感谢您的帮助。

我正在尝试使用 AWSCloudformation init在一些 ec2 实例上安装 docker 和 docker-compose。

在尝试此操作之前，我刚刚成功使用了用户数据

我正在使用这个模板
