Use the AWS CLI to invoke the Lambda function. The function name is in the outputs of the AWS SAM deployment (the key is QueuePublisherFunction):
1. Invoke the Lambda function to publish a message to the SQS queue:
aws lambda invoke --function-name ENTER_YOUR_FUNCTION_NAME outfile.txt.2. Retrieve the message from the SQS queue, using the queue URL from the AWS SAM deployment outputs:
aws sqs receive-message --queue-url ENTER_YOUR_QUEUE_URLCleanup
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"Created by:
