amazon-web-services - AWS Lambda 通过 cloudformation 安排事件源

Question

我已经在 cloudformation 中定义了 lambda/角色，并且还希望使用它来添加计划的事件源...是否有任何文档或示例？

使用Aws::Event::Rule使用 ScheduleExpression 和 AWS::Lambda::Permission

// rule to periodically call the lambda
"TagWatcherRule": {
  "Type": "AWS::Events::Rule",
  "Properties": {
    "ScheduleExpression": "rate(10 minutes)",
    "Targets": [
      {
        "Id": "TagWatcherScheduler",
        "Arn": {
          "Fn::GetAtt": [
            "TagWatcherFunction",
            "Arn"
          ]
        }
      }
    ]
  }
},
// role may call the lambda
"InvokeLambdaPermission": {
  "Type": "AWS::Lambda::Permission",
  "Properties": {
    "FunctionName": {
      "Fn::GetAtt": [
        "TagWatcherFunction",
        "Arn"
      ]
    },
    "Action": "lambda:InvokeFunction",
    "Principal": "events.amazonaws.com",
    "SourceArn": {
      "Fn::GetAtt": [
        "TagWatcherRule",
        "Arn"
      ]
    }
  }
}
