创建Cloudwatch事件规则以通过Terraform更改任务状态

问题描述

我想根据我的ECS集群通过terraform更改任务状态来设置Cloudwatch事件规则。每当任务进入STOPPED或RUNNING状态时，我都会收到通知。

无论任何一个事件发生，此规则都将起作用并匹配吗？然后，我将相应地创建资源“ aws_cloudwatch_event_target”：

resource "aws_cloudwatch_event_rule" "ecs-sns-rule" {
  name = "ecs task state change"
  
  event_pattern = <<PATTERN
{
  "source": [
    "aws.ecs"
    ],"detail-type": [
    "ECS Task State Change"
    ],"detail": {

    "lastStatus": [
      "STOPPED","RUNNING"
    ],"clusterarn": "arn:aws:ecs:us-west-2:XXXXXXXXX:Cluster/XXXXXXXX"
}
}
PATTERN
}

解决方法

来自docs：

匹配值总是数组。

因此，我认为您可以尝试以下操作（假设其他条件都很好）：

resource "aws_cloudwatch_event_rule" "ecs-sns-rule" {
  name = "ecs task state change"
  
  event_pattern = <<PATTERN
{
  "source": [
    "aws.ecs"
    ],"detail-type": [
    "ECS Task State Change"
    ],"detail": {

    "lastStatus": [
      "STOPPED","RUNNING"
    ],"clusterArn": ["arn:aws:ecs:us-west-2:XXXXXXXXX:Cluster/XXXXXXXX"]
}
}
PATTERN
}
