Create an EventBridge rule that invokes a Lambda function
This template deploys a Lambda function that is triggered by an EventBridge rule. In this example, the rule filters for specific attributes in the event before invoking the function.
The Events section of the AWS::Serverless::Function type also sets up the required permissions for EventBridge to invoke this specific function.

Use the AWS CLI to send a test event to EventBridge and observe the event delivered to the Lambda function:
1. Send an event to EventBridge:
aws events put-events --entries file://event.json.2. Retrieve the logs from the Lambda function:
sam logs -n ENTER_YOUR_CONSUMER_FUNCTION_NAME.Cleanup
1. Delete the stack:
sam delete --stack-name STACK_NAME.2. Confirm the stack has been deleted:
aws cloudformation list-stacks --query "StackSummaries[?contains(StackName,'STACK_NAME')].StackStatus"
