我已经在 cloudformation 中定义了 lambda/角色,并且还想用它来添加计划的事件源...是否有任何文档或示例?
Use AWS::事件::规则 http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-events-rule.html with a ScheduleExpression
and a 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"
]
}
}
}
