通过 terraform 为任务状态更改创建 Cloudwatch 事件规则

Question

我想通过 terraform 根据 ECS 集群的任务状态更改设置 Cloudwatch 事件规则。当任务进入“已停止”或“正在运行”状态时，我希望收到通知。

每当任一事件发生时，这条规则都会起作用并匹配吗？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
}

来自文档：

匹配值始终位于数组中。

因此，我认为您可以尝试以下操作（假设其他一切都很好）：

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
}
