eventbridge-scheduler-cfn

This is an example implementation of building a Lambda Function that is executed periodically by EventBridge Scheduler. Scheduler resources are defined by CfnResource.

Resources

Lambda::Function

• Runtime: go1.x
• Timeout: 30 sec
• Memory: 128 MB
• Operation:

  • Just output Hello AWS CDK with Golang. with Request ID and current time to standard output.

  • If invoked as a "RequestResponse", it returns a response similar to the following:

    {
      "message": "Hello AWS CDK with Golang.",
      "requestId": "71bd4fd1-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
      "timestamp": 1658236882
    }

Scheduler::Schedule

• ScheduleExpression: cron(* * */2 * ? *)
• Target: Lambda::Function

Usage

Build the function

make build

Deploy

cdk synth

cdk deploy

Check the execution log

aws logs get-log-events \
--log-group-name '/aws/lambda/hello-aws-cdk-golang-scheduler-function' \
--log-stream-name "$(
  aws logs describe-log-streams \
  --log-group-name '/aws/lambda/hello-aws-cdk-golang-scheduler-function' \
  --query 'max_by(logStreams[], &lastEventTimestamp).logStreamName' \
  --output text)" \
--limit 20 \
--query 'events[].[join(``, [ to_string(timestamp) ,`: `,message])]' \
--output text
