I already have my lambda / roles defined in cloudformation and would love to also use it to add a scheduled eventsources ... are there any docs or examples around ?
Use Aws::Event::Rule 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"
]
}
}
}
